Background: Truncal blocks contribute to multimodal analgesia that enhances early recovery after caesarean delivery. The transversus abdominis plane (TAP) block is an established technique that offers somatic abdominal wall analgesia. The erector spinae plane (ESP) block is a fascial plane technique that may offer additional visceral analgesic effects. This study hypothesized that ESP block would offer superior analgesic efficacy to TAP block in women undergoing caesarean delivery under spinal anaesthesia., Methods: Sixty-six ASA physical status grade 1-3 (≥18 years) patients undergoing elective caesarean delivery under spinal anaesthesia were randomly allocated to receive either bilateral ultrasound-guided TAP (N = 33) or ESP blocks at the T9 vertebral level (N = 35). The primary outcome measure was 24-hour cumulative morphine consumption. The secondary outcomes included time to first analgesic request, duration of block placement, numeric rating scale (NRS) pain scores at rest and movement, effect of pain on activities of daily living (ADLs) and care for the infant, patient analgesic satisfaction, frequency and severity of opioid-related side effects., Results: There was no statistically significant difference in mean (95% CI) 24-hour cumulative morphine consumption between groups: 32.0 (27.0 to 37.0) mg with TAP versus 27.0 (19.9 to 34.0) mg with ESP (p = 0.16). The mean (SD) duration of block placement was longer for ESP than for TAP blocks (10.7 (2.2) minutes versus 9.0 (2.5) minutes; p = 0.004). There were no significant differences in the other secondary outcomes., Conclusion: This study found similar postoperative opioid use and analgesic efficacy between ESP and TAP block after caesarean delivery performed under spinal anaesthesia., Trial Registration: South African National Clinical Trial Registry (DOH-27-102022-5278): https://sanctr.samrc.ac.za/TrialDisplay.aspx?TrialID=8100, Pan African Clinical Trials Registry (PACTR202301645957324): https://pactr.samrc.ac.za/TrialDisplay.aspx?TrialID=24267., (Copyright © 2024 The Author(s).

Background: The use of general anaesthesia (GA) for caesarean delivery (CD) introduces the risk of both difficult and failed intubation. Various strategies may be utilised to reduce this risk; however, not all are supported by evidence. We analysed the rate of difficult intubation following implementation of three recommendations specific to airway management in CD., Methods: This was a retrospective single-center study of CD cases performed under GA at a tertiary care center between January 2013 and December 2022. Cases with GA induced after delivery or with incomplete airway management records were not included in the analysis. We compared outcomes for cases before (2013-2018) versus after (2019-2022) implementation of three specific recommendations: (1) video laryngoscopy (VL) for the first intubation attempt; (2) the presence of a second anesthetist; (3) use of endotracheal tube size 6.5 mm. The primary outcome was difficult intubation, defined as a composite variable (> 1 intubation attempt, use of a rescue device, SpO 2  < 90%). We conducted univariable and adjusted analyses of plausible variables associated with difficult intubation, including age, body mass index, predicted difficult airway, and each of three recommendations., Results: We identified 1462 cases, 922 before and 540 after implementation. The frequency of difficult intubation was similar with 239 (25.9%) before versus 135 (25.0%) after implementation (p = 0.71; 95% CI -0.03 to 0.05). The recommendations were not associated with a decreased likelihood of difficult intubation in the univariable and adjusted models. Adoption of all three recommendations was significantly more frequent in the post-implementation period., Conclusion: Implementation of standardised airway management recommendations had no significant impact on difficult intubation rate, though adoption of all three recommendations was not universal., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Clinical management of pregnant women with morbid obesity poses challenges in performing neuraxial anesthesia as well as positioning for cesarean delivery. Occupational injuries are also known to occur while caring for patients with morbid obesity. We describe two novel approaches to assist neuraxial anesthesia administration and positioning for cesarean delivery. With the assistance of the Institution's Safe Patient Handling and Mobility Team, a universal high-back sling can be placed to lift the patient into a sitting position before neuraxial anesthesia procedure. After placement of combined spinal epidural anesthesia, the ceiling lift is used to lift the patient into a seated position and then rotate to the appropriate location on the operating room table to facilitate supine positioning. The lifting system reduces shearing of the patient's posterior and compromising the epidural site. Team members also report reduced effort required when positioning patients from seated to supine on the operating room table. The second approach is the application of Traxi TM abdominal pannus retractor to retract fat folds encroaching on the epidural placement site in pregnant women with morbid obesity. This is particularly useful when the traditional taping of fat folds away from the site is inadequate. The pannus retractor results in a flatter surface facilitating epidural placement. We have introduced these two approaches into our clinical practice for pregnant women with morbid obesity requiring cesarean delivery under neuraxial anesthesia., (Copyright © 2024 Elsevier Ltd.

Introduction: Intraoperative and postoperative nausea and vomiting (IONV and PONV) are common during cesarean delivery (CD) with neuraxial anesthesia. Limited information exists on the antiemetic benefit of combined P6 acupoint stimulation with acupressure (P6 acupressure) and pharmacologic antiemetics on preventing IONV and PONV after CD. This study assessed the antiemetic efficacy of P6 acupressure compared to a non-P6 acupoint stimulation with acupressure (sham acupressure) in preventing IONV during CD., Methods: We performed a randomized double-blinded trial comparing the efficacy of intraprocedural P6 acupressure versus sham acupressure in preventing IONV during CD after following the Society for Obstetric Anesthesia and Perinatology enhanced recovery recommendations. Subjects were instructed to apply additional pressure at the acupressure sites when they perceived nausea. The primary outcome was the incidence of IONV, and the secondary outcome was the need for rescue antiemetic treatment., Results: Ninety-nine P6 acupressure and 100 sham acupressure subjects were studied. There was no difference in the incidence of intraoperative nausea (67%), vomiting (17%), emesis episodes, or the need for rescue antiemetics intraoperatively. There were also no differences in the incidence of PONV and antiemetic treatment from PACU to discharge. At discharge, 70% of respondents reported experiencing nausea, but only 10% reported it affected self-care. Approximately 50% of the patients in both groups were satisfied with acupressure therapy., Conclusion: P6 acupressure did not reduce the incidence of IONV or PONV when combined with antiemetic therapy per enhanced recovery recommendations. There does not appear to be sufficient evidence to support using P6 acupressure for IONV prevention., (Copyright © 2024 Elsevier Ltd. All rights reserved.)

Objective: The aim of our study was to investigate whether temporary clamping of the bilateral common iliac artery (BCIA) has a role in reducing intraoperative blood loss in patients with segmentally resected anterior placenta percreta or not., Methods: This prospective observational study included patients with anterior placenta percreta who underwent cesarean segmental resection either with BCIA temporary clamping or without clamping between October 2022 and September 2023., Results: A comparison of demographic, obstetric, and surgical parameters and the need for transfusion (except for postoperative erythrocyte suspension transfusion) between the two groups revealed no significant difference (P > 0.05). In contrast, the amount of intraoperative blood loss (P = 0.001) (1974 ± 749 mL vs 2702 ± 615 mL) and postoperative erythrocyte suspension transfusion (P = 0.046) in patients who underwent BCIA temporary clamping were significantly lower than in those who did not undergo BCIA temporary clamping., Conclusion: Temporary clamping of BCIA plays a significant favorable role both in reducing blood loss and the need for postoperative transfusion in patients with placenta percreta who underwent segmental uterine resection., (© 2024 International Federation of Gynecology and Obstetrics.)

Background: Phenylephrine infusion is recommended to prevent spinal hypotension during cesarean delivery (CD) but may be associated with dose-dependent side effects. We hypothesized that adding intermittent pneumatic compression (IPC) of the lower legs to a variable-rate phenylephrine infusion will reduce the dose of phenylephrine required during CD., Methods: Seventy-six healthy women undergoing elective CD under combined spinal-epidural anesthesia were randomly assigned to IPC or control groups (n = 38 per group). After spinal anesthesia, IPC of the lower legs was initiated in the IPC group, and all women received a phenylephrine infusion starting at 25 μg·min -1 and increasing by 16.7 μg·min -1 for systolic blood pressure (SAP) < 90% baseline. If hypotension (SAP < 80% baseline) occurred, 100 μg phenylephrine bolus was administered. The primary outcome was the dose of phenylephrine per minute., Results: The dose of phenylephrine per minute (34.4 ± 7.3 μg·min -1 vs. 40.9 ± 9.5 μg·min -1 , P = 0.001; mean difference -6.6 μg·min -1 , 95% CI -10.5 to -2.7 μg·min -1 ) and the incidence of hypotension (24% vs. 55%, P = 0.005) were lower in the IPC group than in the control group. There were no significant differences between the two groups in the total dose of phenylephrine (603.2 ± 217.1 μg vs. 706.2 ± 247.5 μg, P = 0.058; mean difference -102.9 μg, 95% CI -209.4 to 3.5 μg), maternal side effects, or neonatal outcomes., Conclusions: Intermittent pneumatic compression combined with a variable-rate phenylephrine infusion reduced the phenylephrine dose per minute and the incidence of hypotension during CD under spinal anesthesia., (Copyright © 2024.

Placenta accreta spectrum (PAS) is among the most dangerous obstetric conditions due to elevated risk of massive hemorrhage. Ultrasound is PAS's preferred screening method. This article -introduces the new topographic classification of PAS, allowing for treatment selection, whether radical or conservative. This classification enables considering the One-Step Conservative Surgery (OSCS), a technique that could potentially avoid up to 80% of cesarean -hysterectomies in cases of PAS. This article details the procedure and -eligibility criteria for the OSCS. This promising technique could significantly reduce maternal morbidity and mortality. Finally, the possibility of training in these techniques through telemedicine opens new avenues for conservative uterine treatment in the -context of PAS., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Introduction: Previously, we demonstrated that patients with full-term singletons and preterm twins require similar dose of intrathecal hyperbaric ropivacaine. However, these findings may be attributable to enrolled patients with preterm twin pregnancies. In this study, we aimed to determine the intrathecal dose requirements of hyperbaric ropivacaine for twins and singletons at equal gestational ages., Methods: We enrolled 75 patients with preterm singletons and 75 patients with preterm twins scheduled for cesarean delivery under combined spinal-epidural anesthesia in this two-arm parallel, randomized, double-blind, dose-response study. Patients with singletons and twins were randomly assigned to receive one of five different doses of hyperbaric ropivacaine: 10, 12, 14, 16, or 18 mg. A probit regression model was used to determine the dose effective in 50% of patients (ED 50 ) and dose effective in 90% of patients (ED 90 ) values. The relative median potency was calculated to compare the ED 50 between patients with twins and singletons., Results: Intrathecal ropivacaine ED 50 and ED 90 (with 95% CI) in patients with preterm singletons were 9.9 (7.2 to 11.5) mg and 16.8 (14.5 to 22.9) mg, respectively. In patients with preterm twins, these values were 9.2 (95% CI 6.4 to 10.8) mg and 15.6 (95% CI 13.6 to 20.6) mg. Between patients with preterm twins and preterm singletons, the relative potency (ED 50 ratios) was 0.933 (95% CI 0.72 to 1.15)., Conclusions: During preterm gestation, intrathecal hyperbaric ropivacaine dose requirements for scheduled cesarean delivery were not different between patients with twins and singletons., Trial Registration Number: ChiCTR2100051382., Competing Interests: Competing interests: None declared., (© American Society of Regional Anesthesia & Pain Medicine 2024.

Purpose: The purpose of our study was to determine the minimum effective dose of oxytocin maintenance infusion required to maintain adequate uterine tone in 90% of patients (ED 90 ) after administration of the initial bolus at elective Cesarean delivery (CD) under spinal anesthesia., Methods: We conducted a prospective, double-blind dose-finding study with biased coin up-down design. Immediately after delivery, a 1-IU oxytocin bolus was administered, followed by a maintenance infusion. The obstetrician assessed the uterine tone by palpation as satisfactory or unsatisfactory. In case of unsatisfactory response, the dose for the next patient was increased by 2 IU·hr -1 . For satisfactory response, the dose for the next patient was either decreased by 2 IU·hr -1 with a probability of 1/9, or remained unchanged. The primary outcome was a satisfactory uterine tone from five minutes after delivery until discharge from postanesthesia care unit. The secondary outcomes were blood loss, need for additional uterotonics, and side effects., Results: We analyzed data for 40 patients. The ED 90 of oxytocin maintenance infusion was 4.5 IU·hr -1 (95% confidence interval, 3.3 to 5.5) based on the isotonic regression estimator. The median [interquartile range] blood loss was 861 [553-1,181] mL; 18% received additional uterotonics, and 38% developed hypotension post delivery., Conclusion: Based on the results of this dose-finding study, we recommend a maintenance infusion rate of 4.5 IU·hr -1 following an oxytocin bolus of 1 IU for adequate uterine tone in pregnant patients undergoing elective CDs. This infusion rate is four-fold lower than that required without an initial bolus., Study Registration: ClinicalTrials.gov ( NCT04946006 ); first submitted 25 June 2021., (© 2024.

Background: The increase in the use of induction of labor is a worldwide phenomenon in the current management of labor and delivery in Western societies, with approximately one out of every 4 pregnancies undergoing this procedure This has led women to seek various methods for stimulation of the onset of labor. Some data suggest that the use of acupuncture for favoring spontaneous labor onset could reduce the number of inductions of labor procedures. However, good quality evidence in this respect is not yet available., Objective: The aim of this study was to evaluate the effectiveness of acupuncture using a filiform needle to induce spontaneous onset of labor in women with a scheduled induction of labor date and assess the safety and satisfaction of women undergoing acupuncture., Study Design: We conducted a multicenter, randomized, controlled, parallel-arm, unmasked trial in 3 hospitals in Spain. Eligible participants were women older than 18 years with a singleton pregnancy and a cephalic presentation, scheduled for induction of labor following center-specific protocols. Participants were randomly allocated to one of 2 groups: the intervention group, which underwent acupuncture sessions for a maximum of 4 days prior to the scheduled induction of labor, or the control group, which received no specific prelabor intervention. The primary study outcome was the proportion of women admitted because of spontaneous onset of labor or premature rupture of membranes before or the day of the scheduled induction of labor., Results: Between November 2017 and June 2023, 212 women were recruited and included in the analysis (106 in the acupuncture group and 106 in the control group). There were no significant differences between the 2 groups in the baseline demographic characteristics. Regarding the primary outcome, 65.1% (69/106) of women in the acupuncture group and 39.6% (42/106) in the control group were admitted for spontaneous onset of labor or premature rupture of membranes (P<.001). Overall, women in the intervention group were admitted 1.25 days before (SD 1.4) their scheduled induction of labor date compared to 0.67 days (SD 1.15) for those in the control group (P=.001). The median time from recruitment to hospitalization was 4.48 days for the acupuncture group and 5.33 days for the control group (HR 0.52, 95% CI 0.35-0.77, P=.001). There were no significant differences between the 2 groups regarding the time from admission to delivery or the cesarean delivery rate. Nor were there differences in the rates of maternal or neonatal outcomes, and no maternal or fetal deaths occurred in either group., Conclusion: Acupuncture with filiform needles, administered 4 days prior to scheduled induction of labor increased admission for spontaneous onset of labor and premature rupture of membranes before the induction of labor date., (Copyright © 2024 Elsevier Inc.

Background: Hospital stay after an uncomplicated delivery is typically 2 days for vaginal birth and 3 days for cesarean birth. Health maintenance organizations and third-party payers have encouraged shorter maternity stays. The safety of earlier discharge is unclear particularly when it comes to patients diagnosed with hypertensive disorders of pregnancy (HDP)., Objective: To examine whether expedited discharge amongst patients with HDP will have a negative effect on postpartum readmission rate and blood pressure related complications., Study Design: This was a single academic center retrospective cohort study of patients with HDP (gestational hypertension, preeclampsia, or chronic hypertension) for 2 epochs: 2015-2018, prior to implementation of an expedited discharge policy, and 2019-2020 after hospital wide implementation of expedited postpartum discharge. The expedited discharge policy entailed patients being discharged home as soon as day 1 after a vaginal delivery and day 2 after a cesarean delivery. The primary outcome was unplanned health care utilization postpartum, defined as emergency department (ED) visits, unscheduled clinic visits, and hospital readmission. Secondary outcomes were planned postpartum visits attendance, antihypertensive medication initiation after discharge, and blood pressure control throughout the first year. Bivariable and multivariable logistic regression analyses were run to evaluate the association between expedited discharge and primary and secondary outcomes., Results: A total of 1,441 patients were included in the analysis. There were no statistically significant differences in the rate of unplanned health care utilization (11.3% in the standard postpartum discharge group vs. 13.8% in the expedited discharge group, P=.17). Systolic and diastolic blood pressures did not differ between the groups at 1-2 weeks, six weeks, and one year postpartum. Patients in the expedited discharge group were more likely to attend the 1-2-week postpartum blood pressure check (58.7% vs. 51.7%, P=.02, adjusted OR 1.33, 95% CI 1.08-1.77). Other secondary outcomes did not differ between the two cohort groups., Conclusion: In this single academic center study, expedited discharge after delivery in patients with HDP was not associated with a higher rate of unplanned healthcare utilization postpartum., (Copyright © 2024 Elsevier Inc.

Purpose of Review: Pain management is a critical aspect of care during and following a cesarean delivery. Without proper control of pain, individuals can experience poor mobility, increased thromboembolic events, and difficulty caring for the neonate in the postpartum period. There have been multiple methods for pain management for cesarean delivery and intrathecal morphine (ITM) has emerged as a prominent option for post-operative analgesia due to its efficacy, safety, and potential benefits over other treatments. This review analyzes data on efficacy, side effects, and safety of ITM and the pain control alternatives., Recent Findings: A comprehensive literature review was conducted to compare ITM with other analgesic techniques in post-cesarean patients. ITM was found to be as effective or better than other analgesic options, including bilateral quadratus lumborum block (QLB), opioid-free epidural analgesia (CSEA-EDA), and intravenous fentanyl. One study found that both ITM and oral analgesia were effective in pain control and that ITM caused fewer breakthrough pain events but had a longer duration and a greater rate of side effects than oral opioid analgesia. Commonly observed side effects of intrathecal opioids include nausea, vomiting, pruritus, and urinary retention, and it is thought that the adverse effects from intrathecal administration of opioids are short-lived. ITM may provide a decreased risk of DVT and coagulation by decreasing lower extremity weakness and numbness, thereby decreasing recovery time and increasing mobility. ITM is a safe and effective option for post-cesarean analgesia, with comparable pain relief to alternative forms of pain control, and side effects that are generally manageable. Further research is warranted to explore beneficial combinations with other methods of pain management and optimal dosing strategies., (© 2024.

Background: Caesarean section is a widely performed surgical procedure that often results in moderate-to-severe postoperative pain. If left untreated, this pain can lead to short-term and long-term consequences. Transversalis fascia plane (TFP) block and transversus abdominis plane (TAP) block are among the regional anaesthesia techniques employed for managing pain after a caesarean section., Objective: We aimed to compare the impact of these two blocks on the quality of recovery in patients undergoing elective caesarean section under spinal anaesthesia., Design: A single-centre, double-blind, randomised trial., Settings: Operating room, postanaesthesia recovery unit, and ward in a tertiary hospital., Participants: Ninety-three patients (ASA 2 to 3) were recruited. After exclusion, 79 patients were included in the final analysis: 40 in the TFP block group and 39 in the TAP block group., Interventions: After surgery, participants received either TFP block (20 ml 0.25% bupivacaine for each side) or TAP block (20 ml 0.25% bupivacaine for each side)., Main Outcome Measures: The primary outcome was the difference in obstetric quality of recovery 11-Turkish (ObsQoR-11T) scores between groups. Secondary outcomes included pain scores, opioid consumption and incidence of opioid-related complications., Results: The mean ObsQoR-11T score was higher in the TFP block group compared with the TAP block group (97.13 ± 6.67 points vs. 87.10 ± 9.84 points, respectively; P  < 0.001). The pain scores in the TFP block group were slightly lower between postoperative 4 and 24 h. The mean total morphine consumption was 15.08 ± 2.21 mg in the TFP block group and 22.21 ± 3.04 mg in the TAP block group ( P  < 0.001). More patients required rescue analgesia between 4 and 8 h in the TAP block group [2.00 (5.00%) vs. 9.00 (23.08%), P  = 0.02]. No significant differences were observed between groups in terms of opioid-related side effects., Conclusion: TFP block used for analgesic purposes yielded a better quality recovery period than TAP block and also reduced opioid consumption., Trial Registration: Clinicaltrials.gov (NCT05999981)., Visual Abstract: http://links.lww.com/EJA/B6 ., (Copyright © 2024 European Society of Anaesthesiology and Intensive Care.

Further study is needed to determine the safest mode of delivery and anesthetic management for parturients with ventriculoperitoneal shunts (VP). Prior recommendation for delivery in women with ventriculoperitoneal shunts was cesarean delivery. However, both vaginal delivery and neuraxial anesthesia have been shown to be safe in women with appropriately functioning VP shunts. We present a case series of parturients with VP shunt. Parturients with VP shunts were identified and VP shunt placement indications, neurologic symptoms during pregnancy, delivery mode, anesthetic type, and postpartum complications were reviewed. Forty patients were identified, and fifteen women with twenty deliveries were included. Two women experienced neurological symptoms during pregnancy and one required postpartum shunt revision for blurry vision and ataxia. There were ten cesarean deliveries and ten vaginal deliveries (eight normal spontaneous, one vacuum assisted, and one forceps assisted). Assisted vaginal deliveries were performed to decrease Valsalva including the patient with neurological symptoms related to shunt malfunction. Of the vaginal deliveries, six (60%) had epidural analgesia. Anesthesia for cesarean delivery included neuraxial anesthesia (n = 5) and general anesthesia (n = 5). In our cohort, women with VP shunt received neuraxial blockade without complication. Neuraxial techniques should be offered to women with appropriately functioning VP shunt., (© 2024.

Objective: This study aims to assess the efficacy of laparoscopic modified uterine incision pressure repair in treating type II-III cesarean scar pregnancy (CSP)., Methods: A total of 20 patients diagnosed with type II-III CSP and admitted to the Affiliated Hospital of Guizhou Medical University between April 2021 and May 2023 were enrolled. The patients were divided into two groups: the study group (Group A), consisting of newly treated surgical patients, and the control group (Group B), including patients with type II-III CSP treated by doctors of similar grade and surgical experience (non-novel). Various parameters, including age, menopause duration, pregnancy and delivery history, cesarean section frequency, preoperative human chorionic gonadotropin (HCG) levels, pregnancy sac size, HCG turnover time, operation duration, intraoperative blood loss, blood transfusion requirements, and hospitalization costs, were compared., Results: When comparing mean age, menopause duration, preoperative HCG levels, pregnancy and cesarean section frequencies, pregnancy sac size, and HCG turnover time, no statistically significant differences were observed (P > .05). The number of transfusions and hospitalization costs in Group A were lower than in Group B, although the differences were not statistically significant (P > .05). However, operative time, intraoperative bleeding, and hospitalization costs were significantly lower in Group A compared to Group B (P < .05)., Conclusions: The laparoscopic modified uterine incision pressure repair method demonstrated clinical value with its advantages of short operation time, reduced bleeding, lower costs, and rapid recovery for type II-III CSP.

Purpose: To compare the success rate of a trial of labor (TOL) in a cohort of patients with pelvic fractures, with and without internal fixation, in order to better counsel patients and avoid unnecessary cesarean section (CS)., Methods: A retrospective review of 35 female patients with 28 pelvic ring, five acetabular, and two combined fractures that had subsequent pregnancy; 12 patients had operative fixation and 23 did not. Fracture classification, treatment, type of fixation, mode of deliveries, and reason for CS were documented., Results: The rate of vaginal delivery, unscheduled CS, and scheduled CS across all patients was 80.0% (n = 28), 14.3% (n = 5), and 5.7% (n = 2), respectively, which was similar to institutional rates of 87.0, 12.0, and 1.0%. A TOL was attempted in 91.4% (32/35) and successful in 87.5% (28/32). Patients who failed a TOL were more likely to have Tile B/C pelvic fractures (100.0 vs. 30.4%, observed difference (OD) 69.6%, 95% confidence interval (CI) 16.4, 86.3%; p = 0.01) and more pelvic displacement (6.0 vs. 1.5 mm, OD 4.0, CI 1.0, 18.0; p = 0.01). The fixation and control groups had no observed difference in successful TOL (72.7% vs. 95.2%, OD 22.5%, - 49.7%, 5.5%; p = 0.10)., Conclusions: A majority of women had successful vaginal deliveries after pelvic fractures, with or without fixation, suggesting that these patients should consider a TOL., Level of Evidence: Diagnostic Level III., (© 2023.

Background: Hemorrhage associated with placenta accreta spectrum (PAS) is a leading cause of maternal morbidity and mortality. Estimating blood loss in these individuals is a critical component of comprehensive preoperative planning., Objective: A semiquantitative score based on transvaginal ultrasound was developed and tested to predict PAS, estimate its severity, and blood loss in individuals with clinical and ultrasound evidence suggesting PAS., Study Design: A secondary analysis was conducted of prospectively collected data from a quaternary center of patients with suspected accreta on 2D ultrasound and clinical suspicion. A predetermined scoring system was applied based on three components: (1) uterine wall (score 0: no loss of hypo-translucent uterine wall with overlying placenta in the lower uterine segment; 1: loss of hypo-translucent <3-cm defect; 2: 3-6-cm defect; and 3: >6-cm defect); (2) arterial vascularity at the uterine wall defect (score 0: no vessels observed; 1: 1-2 vessels over the defect; 2: 3-5 vessels; and 3: >5 vessels); and (3) cervical involvement (score 0: normal cervical length without previa; 1: previa with normal cervical length; 2: short cervix with previa, minimal vascularity and small lacunae; 3: short cervix with previa, increased vascularity and large lacunae). Each patient's three domain scores determined a cumulative, final score of 0-9. Patients were managed at the discretion of a multi-disciplinary team and patient's preference among the following options: cesarean delivery with placenta removal, cesarean delivery with placenta in-situ (conservative) with or without delayed hysterectomy, or cesarean hysterectomy. The frequency of different degrees of placental invasion per pathology examination per score unit was registered. Multiple linear regression analysis was performed for association of blood loss according to score adjusted by risk factors for PAS., Results: A total of 73 patients were evaluated. All 11 patients who had a score of 0 had cesarean delivery with placenta removal without evidence of intraoperative PAS, thus resulting in a 100% negative predictive value. The remaining 62 had scores between 1 and 9. Among patients with scores 0-3 (n=20), only one had intraoperative PAS, yielding a negative predictive value of 97%. Higher scores were associated with severe PAS forms (r=0.301, P=.02). Based on the associations between PAS scores, clinical correlation, and blood loss, we divided patients into four categories: Category 0: PAS score 0; Category 1: scores 1-3; Category 2: scores 4-6; and Category 3: scores 7-9. The median blood loss in Category 0=635±352 mL, Category 1=634±599 mL, Category 2=1549±1284 mL, and Category 3=1895±2106 mL (P<.001). On multivariable analysis, Category 2 (β=0.97, P<.01) and Category 3 (β=1.26, P<.003) were associated with significantly greater blood loss than Category 0, irrespective of type of surgery., Conclusion: The transvaginal ultrasound score separates groups at low risk (Category 0) and at higher risk of PAS (Categories 1-3). Categories 1-3 may provide important clinical information to estimate the risk of severe forms of PAS and of blood loss during surgery. VIDEO ABSTRACT., (Copyright © 2024 The Author(s).

Purpose: This study retrospectively assessed blood loss during cesarean deliveries for twin and singleton pregnancies using two distinct methods, quantitative estimation measured during cesarean sections and hematocrit-based calculated estimation., Methods: We included scheduled cesarean deliveries for twin or singleton pregnancies at ≥ 34 weeks of gestation. Quantitative blood loss was recorded based on the blood volume in the graduated collector bottle and by weighing the blood-soaked textiles during cesarean sections. The blood loss was calculated using the change in hematocrit levels before and after the cesarean delivery., Results: We evaluated 403 cases including 44 twins and 359 singletons. Quantitative blood loss during cesarean section was significantly higher in twin pregnancies than that in singleton pregnancies (1117 [440] vs 698 [378] mL; p < 0.001). However, no significant differences were observed in the calculated blood loss between the two groups on the day after delivery (487 mL [692 mL] vs 507 mL [522 mL]; p = 0.861). On post-delivery days 4-5, twin pregnancies were associated with a significantly higher calculated blood loss than singleton pregnancies (725 [868] mL vs 444 [565] mL, p = 0.041). Although a significant moderate correlation between quantitative and calculated blood loss was observed in singleton pregnancies (r = 0.473, p < 0.001), no significant correlation was observed between twin pregnancies (r = 0.053, p = 0.735)., Conclusion: Quantitative blood loss measurements during cesarean section may be clinically insufficient in twin pregnancies. Incorporating blood tests and continuous assessments are warranted for enhanced blood loss evaluation, especially in twin pregnancies, owing to the risk of persistent bleeding., (© 2024.

Purpose: To compare patient-controlled epidural analgesia (PCEA) and epidural morphine (EM) for post-cesarean section analgesia in real-world experience from China., Methods: Parturients receiving one dose of EM (1-2 mg), PCEA, or both EM and PCEA from Peking Union Medical College Hospital were retrospectively recruited. Logistic models were used to identify risk factors., Results: Of 1079 parturients enrolled, 919 (85.2%) parturients received only EM, 105 (9.7%) parturients received PCEA, and 55 (5.1%) parturients received both EM and PCEA. Significantly more parturients from EM group requested supplementary analgesia than those from PCEA and PCEA + EM group (583, 63.4% vs 52, 49.5% vs 25, 45.5%, P = 0.001) with more times of supplementary analgesia (1, IQR: 0-2 vs 0, IQR: 0-1 vs 0, IQR: 0-1 times, P < 0.001) and larger amounts of nonsteroidal anti-inflammatory drugs (NSAIDs) (50, IQR: 0-100 mg vs 0, IQR: 0-50 mg vs 0, IQR: 0-50 mg, P < 0.001). In multivariable Logistic regression for the supplementary analgesia risk, the application of PCEA (OR: 0.557, 95%CI 0.396-0.783, P = 0.001) and the use of NSAIDs intraoperatively (OR: 2.996, 95%CI 1.811-4.957, P < 0.001) were identified as independent predictors. A total of 1040 (96.4%) patients received prophylactic antiemetic therapy during surgery. Only 13 (1.2%) and 7 (0.6%) patients in our cohort requested antiemetic and antipruritic drugs, respectively., Conclusion: The use of PCEA was an independent protective factor for supplementary analgesia during the post-cesarean section. Prophylactic antiemetic therapy may reduce the side effects of post-cesarean analgesia., (© 2024. The Author(s) under exclusive licence to Japanese Society of Anesthesiologists.)

Background: Placenta accreta spectrum disorders are associated with a high risk of maternal morbidity, particularly when surgery is performed under emergency conditions. This study aimed to investigate the incidence of emergency cesarean delivery in patients with a high probability of placenta accreta spectrum disorders on prenatal imaging and to compare the maternal and neonatal outcomes between patients requiring emergency cesarean delivery and those not requiring emergency cesarean delivery., Data Sources: MEDLINE, Embase, Cochrane, and ClinicalTrials.gov databases were searched., Study Eligibility Criteria: This study included case-control studies reporting the outcomes of pregnancies with a high probability of placenta accreta spectrum on prenatal imaging confirmed at birth delivered via unplanned emergency cesarean delivery vs those delivered via planned elective cesarean delivery for maternal or fetal indications. The outcomes observed were the occurrence of emergency cesarean delivery; incidence of placenta accreta and placenta increta/placenta percreta; preterm birth at <34 weeks of gestation; and indications for emergency delivery. This study analyzed and compared the outcomes between patients who underwent emergency cesarean delivery and those who underwent elective cesarean delivery, including estimated blood loss; number of packed red blood cell units transfused and blood products transfused; transfusion of more than 4 units of packed red blood cell; ureteral, bladder, or bowel injury; disseminated intravascular coagulation; relaparotomy after the primary surgery; maternal infection or fever; wound infection; vesicouterine or vesicovaginal fistula; admission to the neonatal intensive care unit; maternal death; composite neonatal morbidity; fetal or neonatal loss; Apgar score of <7 at 5 minutes; and neonatal birthweight., Methods: Quality assessment of the included studies was performed using the Newcastle-Ottawa Scale for case-control and cohort studies. Random-effect meta-analyses of proportions, risks, and mean differences were used to combine the data., Results: A total of 11 studies with 1290 pregnancies complicated by placenta accreta spectrum were included in the systematic review. Emergency cesarean delivery was reported in 36.2% of pregnancies (95% confidence interval, 28.1-44.9) with placenta accreta spectrum at birth, of which 80.3% of cases (95% confidence interval, 36.5-100.0) occurred before 34 weeks of gestation. The main indication for emergency cesarean delivery was antepartum bleeding, which complicated 61.8% of the cases (95% confidence interval, 32.1-87.4). Patients who underwent emergent cesarean delivery had higher estimated blood loss during surgery (pooled mean difference, 595 mL; 95% confidence interval, 116.10-1073.90; P<.001), higher number of packed red blood cells transfused (pooled mean difference, 2.3 units; 95% confidence interval, 0.99-3.60; P<.001), and higher number of blood products transfused (pooled mean difference, 3.0; 95% confidence interval, 1.10-4.90; P=.002) than patients who underwent scheduled cesarean delivery. Patients who underwent emergency cesarean delivery had a higher risk of requiring transfusion of more than 4 units of packed red blood cell (odds ratio, 3.8; 95% confidence interval, 1.7-4.9; P=.002), bladder injury (odds ratio, 2.1; 95% confidence interval, 1.1-4.0; P=.003), disseminated intravascular coagulation (odds ratio, 6.1; 95% confidence interval, 3.1-13.1; P<.001), and admission to the intensive care unit (odds ratio, 2.1; 95% confidence interval, 1.4-3.3; P<.001). Newborns delivered via emergency cesarean delivery had a higher risk of adverse composite neonatal outcomes (odds ratio, 2.6; 95% confidence interval, 1.4-4.7; P=.019), admission to the neonatal intensive care unit (odds ratio, 2.5; 95% confidence interval, 1.1-5.6; P=.029), Apgar score of <7 at 5 minutes (odds ratio, 2.7; 95% confidence interval, 1.5-4.9; P=.002), and fetal or neonatal loss (odds ratio, 8.2; 95% confidence interval, 2.5-27.4; P<.001)., Conclusion: Emergency cesarean delivery complicates approximately 35% of pregnancies affected by placenta accreta spectrum disorders and is associated with a higher risk of adverse maternal and neonatal outcomes. Large prospective studies are needed to evaluate the clinical and imaging signs that can identify patients with a high probability of placenta accreta spectrum at birth, patients at risk of requiring emergency cesarean delivery or peripartum hysterectomy, and patients at high risk of experiencing intrapartum hemorrhage., (Copyright © 2024 Elsevier Inc.

Purpose of the Review: With the increasing prevalence of cesarean section globally, the importance of perioperative analgesia for cesarean section is becoming increasingly evident. This article provides an overview and update on the current status of cesarean section worldwide and associated analgesic regimens., Recent Findings: Some recent studies unveiled potential association of neuraxial analgesia might be associated with children's autism, pharmacologic analgesia in obstetric will potentially gain some more attention. Various commonly used techniques and medications for analgesia in cesarean section are highlighted. While neuraxial administration of opioid remains the most classic method, the use of multimodal analgesia, particularly integration of nonsteroidal anti-inflammatory drugs, acetaminophen, peripheral nerve blocks has provided additional and better options for patients who are not suitable for intrathecal and neuraxial techniques and those experiencing severe pain postoperatively. Optimal pain management is crucial for achieving better clinical outcomes and optimal recovery, and with the continuous development of medications, more and better pharmacologic regimen will be available in the future., (© 2024.

Background: Intraoperative hypothermia is a common complication during cesarean section (C-section) and associated with the high maternal mortality and morbidity. This study aimed to explore the risk factors associated with the incidence of intraoperative hypothermia in women who underwent emergency C-section deliveries., Methods: We retrospectively enrolled women who underwent emergency cesarean deliveries from August 2022 to Dec 2023 at Suzhou Municipal Hospital of Anhui Province. Baseline characteristics, thermal status, and perioperative information were extracted. Hypothermia was defined as the onset of a core temperature below 36 °C. Data were compared between patients with and without a hypothermia during surgery. Logistic regression analyses were performed to determine the risk factors for low-temperature-status., Results: Overall, 87 patients were included, and 30 underwent hypothermia during surgery. For women with a normal temperature status, women in the hypothermia group had a lower incidence of receiving active warming methods (52.6% vs. 30%, P = 0.044). In the logistic regression model involving core temperature, a pre-surgery core temperature < 36.5 °C (OR 4.22, 95% CI 1.13-15.63, p = 0.032) and a long surgery duration (per 10 min, OR 1.97, 95% CI 1.24-3.11, p = 0.004) were associated with a high probability of hypothermia. Administering active warming methods to women can reduce the risk of experiencing a hypothermia during emergency C-sections (OR 0.19, 95% CI 0.05-0.63; p = 0.007)., Conclusions: Hypothermia is common in emergency C-section deliveries. It is recommended that active warming methods should be applied to parturient undergoing emergency C-sections more proactively, especially for women who have a low baseline core temperature (< 36.5 °C) and are expected to have a long surgery duration., (© 2024.

Background: Cesarean sections are the most common abdominal surgical interventions worldwide, with increasing rates in both developed and developing countries. Postpartum (hemorrhage PPH) during cesarean sections can lead to maternal morbidity, prolonged hospital stays, and increased mortality rates. Although various non-surgical measures have been recommended for PPH prevention, surgical techniques such as uterine artery ligation and embolization have been used to manage PPH effectively., Objective: This study aimed to evaluate the effectiveness of a surgical technique based on the temporary bilateral clamping of uterine arteries to reduce blood loss during cesarean sections., Methods: A longitudinal prospective, randomized, controlled study was conducted with a preliminary population group of 180 patients at the University Hospital Regional de Málaga from November 2023 to January 2024. The study protocol was approved by the Ethics Committee of the Regional University Hospital of Malaga (protocol 1729-N-23 and registred with ISRCTN15307819|| http://www.isrctn.org/ , Date submitted 12 June 2023 ISRCTN 15307819). The patients were divided into two groups based on whether the clamping technique was applied during their cesarean sections. The study assessed hemoglobin levels before and after surgery, hospitalization durations, and the prevalence of anemia at discharge as the primary outcomes., Results: The patients who underwent the clamping technique demonstrated significant reductions in hemoglobin differences (0.80 g/dL) compared to the control group (1.42 g/dL). The technique also resulted in shorter hospital stays (3.02 days vs. 3.90 days) and a lower prevalence of anemia at discharge (76.2% vs. 60%)., Conclusion: Temporary clamping of uterine arteries during cesarean sections appears to be an effective measure for preventing postpartum hemorrhaging, reducing hospital stays, and decreasing the prevalence of anemia at discharge. Further research with larger sample sizes and standardized indications is warranted to confirm the benefits and potential broader applications of this technique., Trial Registration: ISRCTN 15,307,819., (© 2024.

General anesthesia (GA) is typically recommended for category 1 emergency cesarean delivery (CD). For categories 2-4 emergencies, either regional or GA can be used. The factors influencing the choice of anesthetic technique in these categories remain poorly understood. We analyzed the association between the type of labor analgesia and subsequent anesthetic techniques employed for intrapartum categories 2 and 3 CD. In a prospective longitudinal cohort study, 300 women were consequently enrolled and categorized according to Lucas's classification of CD urgency. The techniques of anesthesia (GA, spinal, and epidural anesthesia [EA]) employed for CD were analyzed with respect to labor analgesia methods (remifentanil patient-controlled analgesia [remifentanil-PCA], EA, and nitrous oxide [N2O]). EA was the most frequent analgesic option (43.8%), followed by remifentanil-PCA (20.7%) and N2O (5.1%), while 30.4% of parturient women received no analgesia. All anesthetic methods showed a significant relationship with analgesic modalities (P < 0.001). Remifentanil-PCA was associated with a higher incidence of GA. Contraindication to EA was the primary factor related to the transition from remifentanil-PCA to GA. Most parturients who received EA were successfully converted to EA. Spinal anesthesia was the most common technique in women using N2O and those without labor analgesia. GA was associated with lower 5-min Apgar scores. The method of labor analgesia was associated with the anesthesia technique employed for categories 2 and 3 CD. This finding may guide patient counseling and intrapartum anesthetic planning. However, the analysis should be cautiously interpreted as the selection of anesthesia is a complex decision influenced by several clinical considerations.

Background and Objectives: This study aimed to assess the impact of monopolar electrocautery on the fetus during cesarean section. Materials and methods: A retrospective analysis was conducted with 552 patients delivered by cesarean section. Patients were grouped based on usage of monopolar electrocautery. In 272 patients, monopolar electrocautery was used to separate the tissues before the delivery. In 280 patients, no electrocautery was used. Newborn vital signs, Apgar scores, umbilical cord blood parameters, newborn serum parameters collected within 6th postpartum hour, and rate of newborn intensive care unit admission were compared. Results: The 1st and 5th minute Apgar scores were significantly higher in the electrocautery group; however, this difference lost its significance at the 10th minute. The median newborn pulse rate (148 (7) vs. 146 (6) beats per minute, p = 0.026), umbilical cord blood pH, and partial oxygen pressure were significantly higher in the electrocautery group compared to the no-electrocautery group (7.34 ± 0.06 vs. 7.31 ± 0.06, p < 0.001, and 25.5 (14.77) vs. 23 (16.08) mmHg, p = 0.025, respectively). The median umbilical cord blood serum calcium level was 1.51 (0.64) mmol/L in the electrocautery group, which was significantly lower than 1.9 (0.82) mmol/L in the no-electrocautery group ( p = 0.002). The incidence of hypoglycemia was significantly lower in the electrocautery group than in the no-electrocautery group (2.2% vs. 5.7%, p = 0.035). Conclusions: Monopolar electrocautery during cesarean section affects the fetus, but it is safe to use it. Electrocautery is independently associated with umbilical cord blood pH and calcium level. Electrocautery may be associated with a lower incidence of hypoglycemia.

Background: Post-dural puncture headache (PDPH) is the most common complication following spinal anesthesia among parturients undergoing cesarean section surgery. The purpose of this study was to evaluate the effectiveness of acetaminophen and caffeine in preventing PDPH., Methods: This double-blind, randomized clinical trial was conducted on 96 obstetric women, who were candidates for elective cesarean section. Following the randomization of participants into two groups, participants in the intervention group received tablets of acetaminophen (500 mg)+caffeine (65 mg), and participants in the control group received placebo tablets orally 2 hours before spinal anesthesia induction and then every 6 hours after surgery up to 24 hours. All parturients were evaluated for frequency and intensity of PDPH every 6 hours until 24 hours after surgery and then 48 and 72 hours after surgery. Overall satisfaction during the first 72 hours of postpartum was evaluated. The data were analyzed using SPSS software. P<0.05 was considered statistically significant., Results: Participants in the intervention group were 70% less likely to experience PDPH after spinal anesthesia (OR=0.31 P=0.01, 95% CI [0.12-0.77]). They also experienced significantly milder headaches 18 hours, 48 hours, and 72 hours later. Participants in the intervention group reported higher levels of satisfaction at the end of the study (P=0.01). No side effects related to the intervention were reported., Conclusion: Prophylactic administration of acetaminophen+caffeine decreases 70% the risk of PDPH and significantly attenuates pain intensity in obstetric patients who underwent spinal anesthesia for cesarean section., Competing Interests: Mohammad Ali Sahmeddini and Naeimehossadat Asmarian, as the Editorial Board Members, were not involved in any stage of handling this manuscript. A team of independent experts was formed by the Editorial Board to review the article without their knowledge., (Copyright: © Iranian Journal of Medical Sciences.)

Objective: To compare the maternal and neonatal morbidity in patients with transvaginal (TVC) versus transabdominal (TAC) cerclage., Materials and Methods: Retrospective analysis of patients who received cervical cerclage and terminated the pregnancy in the second trimester or third trimester in two tertiary hospitals. Data on basic clinical characteristics, predelivery maternal morbidity, intrapartum morbidity, postpartum morbidity and neonatal morbidity of TVC patients and TAC patients were analysed and compared., Results: Seventy-two TVC patients and 120 TAC patients were included. The rates of abnormal fetal presentation and placental disorders were significantly higher in TAC patients than that in TVC patients (21.67% vs 5.56% and 18.33% vs 4.17%, respectively). The rates of premature rupture of membranes and intrauterine infection were significantly higher in TVC patients than that in TAC patients (25.00% vs 2.50% and 11.23% vs 3.33%, respectively). Compared with TVC patients, the rates of estimated intrapartum hemorrhage ≥500 ml, uterine rupture and cesarean delivery in the third trimester were significantly higher in TAC patients than in TVC patients. Gestational age at delivery and neonatal morbidity were comparable between TVC patients and TAC patients., Conclusion: Compared with TVC patients, TAC patients were associated with a significantly higher incidence of maternal morbidity in placental disorders, abnormal fetal presentation, intrapartum hemorrhage ≥500 ml and uterine rupture., Competing Interests: Declaration of competing interest We declare that there are no potential conflicts of interest., (Copyright © 2024.

Background: The role of barbed sutures in preventing myometrial defects and enhancing postpartum outcomes after cesarean section (C-section) is uncertain., Objective: This study compared clinical and ultrasonographic outcomes of uterine scar defects after C-section with barbed and conventional smooth thread sutures., Study Design: This was a multicenter, parallel-group, randomized, controlled clinical trial. Four obstetrics and gynecology departments across three Japanese healthcare regions were included. The participants were women requiring their first cesarean delivery between May 2020 and March 2023. Of the 1211 participants enrolled, 298 underwent C-section and 253 were followed up until July 2023. Participants with singleton pregnancies were randomly assigned (1:1 ratio) to receive either conventional or spiral thread sutures with a double-layer continuous suture. The study period comprised the time of consent to the 6- to 7-month examination. The primary endpoint was the rate of scar niches >2 mm evaluated using transvaginal ultrasonography at 6 to 7 months after surgery. Additional metrics included the total operative time, suture application time, operative blood loss, number of additional sutures required for hemostasis, maternal surgical complications, postoperative infections, surgeon's years of experience, and individual subscale scores., Results: All data of the 220 participants (barbed suture group: 110; conventional suture group: 110) were available, thus enabling a full analysis set. A comparison of the barbed and conventional suture groups, respectively, revealed the following: niche length, 2.45±1.65 mm (range: 1.0-6.7) vs 3.79±1.84 mm (range: 1.0-11.0) (P<.001); niche depth, 1.78±1.07 mm (range: 1.0-5.7) vs 2.70±1.34 mm (range: 1.0-7.3) (P<.001); residual myometrial thickness (RMT), 8.46±1.74 mm (range: 4.8-13.0) vs 7.07±2.186 mm (range: 2.2-16.2) (P<.001); and niche width, 1.58±2.73 mm (range: 0.0-14.0) vs 2.88±2.36 mm (range: 0.0-11.0) (P<.001), respectively. The barbed suture group exhibited no defects and an RMT <3 mm. Furthermore, the barbed suture group had a lower rate of uterine niches (29.1%; n=32/110) than the conventional suture group (68.2%; n=75/110). Secondary outcomes showed no significant differences in operative times, maternal surgical complications, or postoperative complications., Conclusion: Double-layer barbed sutures during cesarean delivery may prevent C-section scar defects and postoperative complications.

In the case of placenta previa-accreta when the placenta covers the entire anterior uterine wall, it is difficult to avoid transecting the placenta by traditional low-transverse cesarean section (CS), resulting in catastrophic hemorrhage and fetal anemia. To prevent this critical risk, we developed the CS with transverse uterine fundal incision (TUFI) and this technique has been widely used as a beneficial surgical method in clinical practice owing to its safety advantages for the mother and neonate since our first report. However, the risk of uterine rupture during a subsequent pregnancy remains unclear. Based on our 17 years of experience, patients who require TUFI do not need to avoid this beneficial operative method simply because of their desire to conceive again, as long as certain conditions can be met. To approve a post-TUFI pregnancy, an appropriate suture method, delay in conception for at least 12 months with evaluation of the TUFI scar, and cautious postoperative management are at a minimum essential. In this article, we showed our recommendation for operative procedure and discuss the current status of the management of post-TUFI pregnancies based on the evaluation of the TUFI wound scar and experience with postoperative pregnancies., (© 2024 Japan Society of Obstetrics and Gynecology.)

Background: The rising rate of cesarean deliveries has led to an increased incidence of long long-term complications, including niche formation in the uterine scar. Niche development is associated with various gynecologic complaints and complications in subsequent pregnancies, such as uterine rupture and placenta accreta spectrum disorders. Although uterine closure technique is considered a potential risk factor for niche development, consensus on the optimal technique remains elusive., Objective: We aimed to evaluate the effect of single-layer vs double-layer closure of the uterine incision on live birth rate at a 3-year follow-up with secondary objectives focusing on gynecologic, fertility, and obstetrical outcomes at the same follow-up., Study Design: A multicenter, double-blind, randomized controlled trial was performed at 32 hospitals in the Netherlands. Women ≥18 years old undergoing a first cesarean delivery were randomly assigned (1:1) to receive either single-layer or double-layer closure of the uterine incision. The primary outcome of the long-term follow-up was the live birth rate; with secondary outcomes, including pregnancy rate, the need for fertility treatment, mode of delivery, and obstetrical and gynecologic complications. This trial is registered on the International Clinical Trials Registry Platform www.who.int (NTR5480; trial finished)., Results: Between 2016 and 2018, the 2Close study randomly assigned 2292 women, with 830 of 1144 and 818 of 1148 responding to the 3-year questionnaire in the single-layer and double-layer closure. No differences were observed in live birth rates; also there were no differences in pregnancy rate, need for fertility treatments, mode of delivery, or uterine ruptures in subsequent pregnancies. High rates of gynecologic symptoms, including spotting (30%-32%), dysmenorrhea (47%-49%), and sexual dysfunction (Female Sexual Function Index score, 23) are reported in both groups., Conclusion: The study did not demonstrate the superiority of double-layer closure over single-layer closure in terms of reproductive outcomes after a first cesarean delivery. This challenges the current recommendation favoring double-layer closure, and we propose that surgeons can choose their preferred technique. Furthermore, the high risk of gynecologic symptoms after a cesarean delivery should be discussed with patients., (Copyright © 2023 The Author(s). Published by Elsevier Inc. All rights reserved.)

Background: The resolution of factors linked to the recurrence of cesarean section defects can be accomplished through a comprehensive technique that effectively addresses the dehiscent area, eliminates associated intraluminal fibrosis, and establishes a vascularized anterior wall by creating a sliding myometrial flap., Objective: Propose a comprehensive surgical repair for recurrent and large low hysterotomy defects in women seeking pregnancy or recurrent spotting., Study Design: A retrospective cohort analysis included 54 patients aged 25-41 with recurrent large cesarean scar defects treated at Otamendi, CEMIC, and Valle de Lili hospitals. Comprehensive surgical repair was performed by suprapubic laparotomy, involving a wide opening of the vesicouterine space, removal of the dehiscent cesarean scar and all intrauterine abnormal fibrous tissues, using a glide myometrial flap, and intramyometrial injection of autologous platelet-rich plasma. Qualitative variables were determined, and descriptive statistics were employed to analyze the data in absolute frequencies or percentages. The data obtained were processed using the Infostat TM statistic program., Results: Following the repair, all women experienced normal menstrual cycles and demonstrated an adequate lower uterine segment thickness, with no evidence of healing defects. All patients experienced early ambulation and were discharged within 24 h. Uterine hemostasis was achieved at specific points, minimizing the use of electrocautery. The standard duration of the procedure was 60 min (skin-to-skin), and the average bleeding was 80-100 ml. No perioperative complications were recorded. A control T2-weighted MRI was performed six months after surgery. All patients displayed a clean, unobstructed endometrial cavity with a thick anterior wall (Median: 14.98 mm, IQR 13-17). Twelve patients became pregnant again, all delivered by cesarean between 36.1 and 38.0 weeks, with a mean of 37.17 weeks. The thickness of the uterine segment before cesarean ranged between 3 and 7 mm, with a mean of 3.91 mm. No cases of placenta previa, dehiscence, placenta accreta spectrum (PAS), or postpartum hemorrhage were reported., Conclusions: The comprehensive repair of recurrent low-large defects offers a holistic solution for addressing recurrent hysterotomy defects. Innovative repair concepts effectively address the wound defect and associated fibrosis, ensuring an appropriate myometrial thickness through a gliding myometrial flap.

Objective: This study aimed to evaluate if placement of transverse cesarean skin incision above or below the overhanging pannus is associated with wound morbidity in morbidly obese patients., Study Design: We identified a cohort of patients with body mass index (BMI) ≥40 kg/m 2 undergoing cesarean delivery at a single center from 2017-2020 with complete postpartum records. Data was abstracted after institutional review board exemption, and patients were grouped by low transverse or high transverse skin incision. The primary outcome was a composite of wound infection, fascial dehiscence, incisional hernia, therapeutic wound vacuum, and reoperation. Secondary outcomes included the individual components of the composite, blood transfusion, operative time, and immediate neonatal outcome. T test and χ 2 were used for continuous and categorical comparisons. Logistic regression was used to compute adjusted odds ratios for categorical outcomes and linear regression to compare operative times adjusting for factors associated with wound complications and surgical duration respectively., Results: 328 patients met inclusion criteria: 65 with high transverse (infraumbilical and supraumbilical) and 263 with low transverse (Pfannenstiel) incision. 11% of patients had wound morbidity; high transverse incision was associated with 3.64-fold increased odds of composite wound morbidity (23.1% vs 8%, aOR 3.64, 95% CI 1.52-8.70) and 5.73-fold increased odds of wound infection (13.8% vs. 4.9%, aOR 5.73, 95% CI 1.83-17.96). Time from skin incision to delivery was 1.87 min longer (11.09 vs 14.98 min, β = 1.87, 95% CI 0.17-4.61). There was no significant difference in neonatal outcomes, non-low transverse hysterotomy, or total operative time., Conclusion: High transverse skin incision for cesarean delivery was strongly associated with increased wound morbidity in morbidly obese patients.

Objective: The purpose of this study was to determine the factors that influence physician preference for type of hysterotomy incisions in gravidas with a singleton or twin pregnancy undergoing cesarean section under 28 weeks, and to assess factors that result in delivery complications, defined as either intraoperative dystocia or hysterotomy extension. We hypothesized that compared to those with non-cephalic presentations, gravidas with a presenting fetus in cephalic presentation would have higher rates of low-transverse cesarean section, and reduced rates of delivery complications with low-transverse hysterotomy., Methods: This was a retrospective cohort chart analysis of 128 gravidas between 23 0/7 and 27 6/7 weeks undergoing cesarean section at a single academic institution between August 2010 and December 2022. Data was abstracted for factors that might influence the decision for hysterotomy incision type, as well as for documentation of difficulty with delivery of the fetus or need for hysterotomy extension to affect delivery., Results: There was a total of 128 subjects, 113 with a singleton gestation and 15 with twins. The presenting fetus was in cephalic presentation in 43 (33.6%), breech presentation in 71 (55.5%), transverse/oblique lie in 13 (10.2%), and not documented in 1 (0.8%). Sixty-eight (53.1%) had a low-transverse cesarean section (LTCS), 53 (41.4%) had a Classical, 5 (3.9%) had a low-vertical hysterotomy and 2 (1.6%) had a mid-transverse incision. There was a significantly higher rate of LTCS among gravidas with the presenting fetus in cephalic presentation (30/43, 69.8%) compared to those with breech (31/71, 43.7%) or transverse/oblique presentations (7/13, 53.8%), p = .03. No other significant associations were related to hysterotomy incision, including nulliparity, racially or ethnically minoritized status, plurality, indication for cesarean delivery, or pre-cesarean labor. Twenty (15.6%) subjects experienced either an intraoperative dystocia or hysterotomy extension. For the entire cohort, there was a greater median cervical dilatation in those with delivery complications (4.0 cm, IQR .5 - 10 cm) compared to those without complications (1.5, IQR 0 - 4.0), p = .03, but no significant association between delivery complications and fetal presentation, hysterotomy type, plurality, or other demographic/obstetrical factors. However, among gravidas undergoing low-transverse cesarean section, only 2/30 (6.7%) with cephalic presentations had a delivery complication, compared to 9/31 (29.0%) with breech presentations and 3/7 (42.9%) with a transverse/oblique lie, p = .03., Conclusion: In pregnancies under 28 weeks, the performance of a low-transverse cesarean section was significantly associated only with presentation of the presenting fetus. Among those with cephalic presentations, the rate of intrapartum dystocia or hysterotomy extension was low after a low-transverse hysterotomy, suggesting that in this subgroup, a low-transverse cesarean section should be considered.

Introduction: It is still no consensus on the use of ropivacaine or bupivacaine in epidural anesthesia for cesarean section (CS), because their anesthetic potency and relative complications remains controversial. This system review and meta-analysis aimed to compare the efficacy of epidural ropivacaine and bupivacaine for elective CSs and investigate relative complications for parturients and neonates., Methods: We searched PubMed, MEDLINE, Embase, Cochrane Library, Science-Direct, and Google Scholar to June 30, 2023 for randomized controlled trials (RCTs), which compared epidural ropivacaine with bupivacaine for elective CSs. The success rate of epidural anesthesia (EA) was primary outcome. The secondary outcomes included onset times of sensory block, maternal side effects, neonatal Apgar scores and umbilical artery pH., Results: We analyzed 8 RCTs with 532 parturients. 0.75% ropivacaine is associated with a shorter onset time of sensory block than 0.5% bupivacaine (SMD = -0.43, 95% CI: -0.70 to -0.17; p  = .001). 0.5% ropivacaine resulted in a reduced nausea than 0.5% bupivacaine (RR = 0.49, 95% CI: 0.28 to 0.83; p  = .008). In addition, there were no significant difference between ropivacaine and bupivacaine groups in terms of success rate of epidural anesthesia, maternal side effects (hypotension, bradycardia, shivering), and neonatal Apgar scores and umbilical artery pH., Conclusions: The findings suggest that there were no significant difference between epidural ropivacaine and bupivacaine for elective CSs in terms of the success rate (85.9% vs. 83.5), maternal side effects (hypotension, bradycardia, shivering), and neonatal Apgar scores and umbilical artery pH. But compared with 0.5% bupivacaine, epidural 0.75% ropivacaine was mildly effective for reducing onset time of sensory block and 0.5% ropivacaine reduced the incidence of maternal nausea.

Introduction: Transversus abdominis plane (TAP) blocks are commonly performed for postoperative analgesia in elective cesarean section. Ropivacaine is the most commonly used local anesthetic for TAP blocks. Currently, the concentration of ropivacaine for TAP blocks is various, and increasing number of randomized controlled trials (RCTs) have compared the effects of different concentration of ropivacaine for TAP blocks in cesarean section. This protocol of a systematic review and meta-analysis aims to identify the optimal concentration of ropivacaine for TAP blocks in elective cesarean section., Methods and Analysis: Databases including PubMed, Web of science, the Cochrane library, and EMBASE will be searched from their inception to May 1, 2024. RCTs that investigated the analgesia of different concentrations of ropivacaine for TAP blocks in elective cesarean section will be identified. The analgesia duration will be the primary outcome. Secondary outcomes will include the analgesics consumption over postoperative 24 hours, postoperative pain scores at rest and movement, and the incidence of adverse effects. RevMan 5.4 software will used for statistical analysis. The evidence quality of synthesized results will be evaluated by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach., Ethics and Dissemination: Ethical approval is not applicable. The results of this study will be published on completion., Trial Registration: PROSPERO registration number: CRD42024496907., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Zhang et al.

Background: Respiratory functions may be impaired in cesarean section (C/S) delivery performed under spinal anesthesia (SA) and oxygen supplementation may be required. Therefore, we conducted a randomized controlled study aimed to evaluate the effects of different oxygen administrations in pregnant women on the lungs during C/S under SA using ultrasound and oxygen reserve index (ORI)., Methods: We conducted a randomized, controlled, single-center study from May 1, 2021, to March 31, 2022. A total of 90 patients scheduled for C/S under SA were randomly divided into 3 groups. Following the SA, patients in group 0 were treated with room air, in Group 3 were administered 3 L/min O₂ with a nasal cannula (NC), in Group 6 were administered 6 L/min O₂ with a simple face mask. In addition to routine monitoring, ORI values were measured. Lung aeration was evaluated through the modified lung ultrasound score (LUS) before the procedure (T0), at minute 0 (T1), 20 (T2), and hour 6 (T3) after the procedure, and ∆LUS values were recorded., Results: After SA, the ORI values of Group 3 were higher than Group 0 at all times (p < 0.05), while the intraoperative 1st minute and the 10th, 25th and 40th minutes after delivery (p = 0.001, p = 0.027, p = 0.001, p = 0.019) was higher than Group 6. When the LUS values of each group were compared with the T0 values a decrease was observed in Group 3 and Group 6 (p < 0.001, p = 0.016). While ∆LUS values were always higher in Group 3 than in Group 0, they were higher only in T1 and T2 in Group 6., Conclusion: We determined that it would be appropriate to prefer 3 L/min supplemental oxygen therapy with NC in C/S to be performed under SA., (© 2024.

Background and objectives : The frontal QRS-T angle is a novel parameter of myocardial repolarization. Weight gain during pregnancy and physiological changes during a cesarian section may affect the frontal QRS-T angle. We aimed to assess the effect of body mass index (BMI) on the frontal QRS-T angle in pregnant women undergoing cesarean section with spinal anesthesia. Method and materials : This study included 90 pregnant women. BMI was calculated for all pregnant women. The study population was divided into two groups: BMI < 30 (n = 66) and BMI ≥ 30 (n = 24). QT interval measurements and the frontal QRS-T angle were obtained from the report of an electrocardiography machine. Results : It was found that the pre-operative and post-operative frontal QRS-T angle ( p = 0.045 and p = 0.007) and QTc interval ( p = 0.037 and p < 0.001) were higher in pregnant women with a BMI ≥ 30 than in pregnant women with a BMI < 30. In addition, when compared to pre-operative values, the post-operative frontal QRS-T angle (from 24.0 [20.0-41.5] to 34.5 [19.5-50.0], p = 0.031) and QTc interval (from 420.6 ± 13.3 to 431.7 ± 18.3, p = 0.010) were increased in the BMI ≥ 30 group, whereas no significant post-operative increase was observed in the BMI < 30 group. In correlation analysis, BMI was positively correlated with the frontal QRS-T angle and QTc interval. Conclusions : The frontal QRS-T angle and QTc interval were importantly increased in pregnant women with a BMI ≥ 30 than in pregnant women with a BMI < 30. Also, after cesarean section operation with spinal anesthesia, the frontal QRS-T angle and QTc were increased significantly in the BMI ≥ 30 group, whereas no significant change was observed in the BMI < 30 group. Therefore, it is suggested to perform close post-operative monitoring in pregnant women with a BMI ≥ 30 undergoing cesarean section with spinal anesthesia.

Background: Cesarean deliveries (CD) are commonly performed using neuraxial anesthesia. The use of neuraxial morphine has proven beneficial in terms of postoperative pain management; however, its effect on postoperative urine retention remains unclear., Objectives: To determine whether morphine injection into the neuraxis during CD influences postoperative urinary retention rate., Methods: We conducted a retrospective case-control observational study of patients undergoing CD. We compared patients using morphine injected into the intrathecal or epidural spaces (November 2020 to October 2021) to a historical cohort of patients undergoing CD without morphine (November 2019 to October 2020). The primary outcome was the rate of postoperative overt urinary retention necessitating bladder catheterization., Results: The study group comprised 283 patients, and 313 patients in the control group were eligible for analysis. No differences were found with respect to the baseline demographic and indication for CD. The number of postpartum urinary bladder catheterizations due to urine retention was higher in the study group (5% vs. 1%, P-value = 0.003). No cases of 30-day readmission were recorded. Moreover, patients treated with neuraxial morphine required fewer repeat doses of postoperative anesthesia (oral analgesia 7.4 vs. 10.1, intravenous analgesia 0.29 vs. 0.31, oral opioids 0.06 vs. 3.70, intravenous opioids 0.01 vs. 0.45, P-value < 0.001 for all)., Conclusions: While neuraxial morphine used during CD appears to be safe and effective, the risk of postoperative urinary retention seems to be increased due to its use. Cases of overt urinary retention treated by bladder catheterization does not lead to short-term complications.

Objective: Second-stage cesarean delivery (CD) is associated with subsequent preterm birth (PTB). It has been suggested that an increased risk of PTB after second-stage cesarean delivery could be linked to a higher chance of cervical injury due to the extension of the uterine incision. Previous studies have shown that reverse breech extraction is associated with lower rates of uterine incision extensions compared to the "push" method. We aimed to investigate the association between the method of fetal extraction during second-stage CD and the rate of spontaneous PTB (sPTB), as well as other maternal and neonatal outcomes during the subsequent pregnancy., Methods: This was a multicenter retrospective cohort study. The study population included women in their first subsequent singleton delivery following a second-stage CD between 2004 and 2021. The main exposure of interest was the method of fetal extraction in the index CD ("push" method vs. reverse breech extraction). The primary outcome of this study was sPTB <37 weeks in the subsequent pregnancy. Secondary outcomes were overall PTB, trial of labor, and other adverse maternal and neonatal outcomes. Univariate analysis was followed by multiple logistic regression modeling., Results: During the study period, 2969 index CD during second stage were performed, of those 583 met the inclusion criteria, of whom 234 (40.1%) had fetal extraction using the reverse breech extraction method, while 349 (59.9%) had the "push" method for extraction. In univariate analysis, women in those two groups had statistically similar rates of sPTB (3.7% vs. 3.0%; odds ratio [OR] 1.25, 95% CI: 0.49-3.19) and overall PTB (<37, <34 and <32 weeks), as well as other maternal, neonatal, and trial of labor outcomes. This was confirmed by multivariate analyses with an adjusted OR of 1.27 (95% CI: 0.43-3.71) for sPTB., Conclusion: Among women with a previous second-stage CD, no significant difference was observed in PTB rates in the subsequent pregnancies following the "push" method compared to the reverse breech extraction method., (© 2024 The Authors.

Background: Induction of labor (IOL) is recommended following prelabor rupture of membranes (PROM). The optimal method for IOL and need for cervical ripening in those with PROM and an unfavorable cervical examination is unclear., Objective: To determine if oxytocin or oral misoprostol results in a shorter time to delivery among nulliparous patients with an unfavorable cervical examination and PROM diagnosis and to evaluate patient satisfaction with both methods., Study Design: This is a randomized clinical trial conducted at an urban tertiary care center from 2019 to 2023. Subjects were nulliparas ≥36 weeks with an unfavorable starting cervical exam (≤2 cm and Bishop <8). The primary outcome was time from IOL to delivery in hours compared between oxytocin vs oral misoprostol. Secondary outcomes included suspected intraamniotic infection, cesarean delivery, composite maternal and neonatal morbidity, and patient satisfaction (assessed by Birth Satisfaction Scale-Revised). Sub-group analyses for those with BMI ≥ 30 kg/m 2 and cervical dilation ≥1 cm were performed. We required 148 subjects to have 80% power to detect a 2-hour difference in time to delivery. The study was stopped early by the data safety monitoring board due to feasibility concerns in recruiting desired sample size., Results: A total of 108 subjects were randomized: 56 oxytocin; 52 oral miso. The median gestational age at induction was 39.5 weeks; the mean starting cervical dilation was 1.1 cm. There was no statistical difference in time to delivery between groups overall: 14.9 hours oxytocin vs 18.1 hours oral misoprostol (P=.06). In sub-group analyses, there was a 5 hours shorter time to delivery with oxytocin for those with a BMI ≥ 30 kg/m 2 (16.6 hours oxytocin vs 21.8 hours oral misoprostol, P .04) and 4.5 hours shorter time to delivery with oxytocin for those with cervix ≥1 cm (12.9 hours oxytocin vs 17.3 hours oral misoprostol, P .04). There were no differences in intraamniotic infection, cesarean delivery, maternal or neonatal morbidity between the groups. Patient satisfaction was higher for those receiving oxytocin compared to misoprostol (29.0 vs 26.3, P=.03)., Conclusion: Among nulliparas with PROM and an unfavorable cervix, there was no difference in overall time to delivery between oxytocin and oral misoprostol. This result should be interpreted with caution given early study discontinuation and inadequate power. However, a shorter time to delivery with oxytocin was noted in obese patients and those with cervical dilation of at least 1 cm. Furthermore, patient satisfaction was higher in the oxytocin group, and there was no increased risk of neonatal or maternal morbidity with oxytocin., (Copyright © 2024 Elsevier Inc.

Objectives: Parturients are at increased risk for difficult airway management with subsequent fetal complications. Videolaryngoscopy was opined to be the new standard of airway care to facilitate orotracheal intubation under urgent care conditions. We examined in parturients requiring general anesthesia for urgent cesarean delivery the association of the type of laryngoscopy technique and time required to facilitate orotracheal intubation with the incidence of subsequent neonatal intensive care unit (NICU) admission., Methods: Following institutional review board approval, 431 parturients aged 18 years and older who underwent urgent cesarean section requiring general anesthesia were entered into this study. Patient characteristics, maternal comorbidities, and indications for urgent cesarean delivery were collected from the electronic medical records from January 2013 to November 2018. Orotracheal intubation times by type of laryngoscopy (video or direct) and NICU admission rates also were collected. A measure of effect size, risk differences with 95% confidence intervals (CIs), were calculated for the likelihood of NICU admission by difficult orotracheal intubation and by type of laryngoscopy used to secure the airway., Results: Videolaryngoscopy as the primary type of laryngoscopy was used in 24.1% (95% CI 20.3%-28.3%) of general anesthetics. The incidence of difficult orotracheal intubation was 4.4% (95% CI 2.8%-6.7%), with a higher incidence observed with videolaryngoscopy (8.7%) than with direct laryngoscopy (3.1%) and a risk difference of 5.6% (95% CI 0.001%-11.3%). The incidence of NICU admission was 38.4% (95% CI 34.0%-43.1%). Times for successful orotracheal intubation were longer with videolaryngoscopy. Videolaryngoscopy had a higher association for NICU admission (47%) than for direct laryngoscopy (36%), with a risk difference of 11.4% (95% CI 0.01%-22.3%)., Conclusions: Videolaryngoscopy did not decrease the incidence of difficult orotracheal intubation, and it did not decrease the time associated with orotracheal intubation. Videolaryngoscopy was associated with a higher association of NICU admission. These results suggest that videolaryngoscopy does not supplant direct laryngoscopy as the standard of care for orotracheal intubation under urgent care conditions of general anesthesia for cesarean section.

Objectives: To systematically review randomized controlled trials (RCTs) and perform a meta-analysis comparing early amniotomy with delayed amniotomy in individuals undergoing pre-induction cervical ripening by Foley balloon. The primary outcome was the rate of cesarean delivery. Understanding the impact of the timing of amniotomy on the rate of cesarean delivery is crucial for obstetricians and healthcare providers when making decisions about the management of labor induction., Data Sources: Data were sourced from electronic databases, including PubMed, OVID, Cochrane Library, Web of Science, and ClinicalTrials.gov through February 2024. The review adhered to Preferred Reporting Item for Systematic Reviews guidelines and registered with PROSPERO (ID CRD42023454520)., Study Eligibility Criteria: Inclusion criteria comprised RCTs comparing early amniotomy with delayed amniotomy in individuals undergoing cervical ripening by Foley balloon. Early amniotomy was defined as amniotomy soon after cervical ripening. Delayed amniotomy was defined as withholding amniotomy until after the onset of the active phase of labor, until at least 4 hours from either initiation of oxytocin or Foley balloon removal/expulsion, or until achieving >4 cm of dilation. Participants included nulliparous or multiparous individuals with singleton pregnancies undergoing labor induction at 37 weeks or later., Study Appraisal and Synthesis: A systematic literature search was conducted using defined search terms including "early amniotomy," "delayed amniotomy," "induction of labor," "cervical ripening," and "Foley balloon," and "Foley catheter." The quality of the included trials was assessed using the Cochrane Risk of Bias Tool for randomized controlled trials. The primary outcome was cesarean delivery. Secondary outcomes included outcomes related to labor duration and neonatal outcomes. Pooled relative risks (RR) and weighted mean differences (WMD) with 95% confidence intervals were calculated., Results: Five trials involving 849 participants undergoing induction and cervical ripening by Foley balloon were included. The rate of cesarean delivery did not differ between individuals randomly assigned to the early amniotomy group compared with those assigned to the delayed amniotomy group (22.9% vs. 23.3%; RR 1.00; 95% CI 0.65-1.55). Early amniotomy compared to delayed amniotomy was associated with a higher proportion of delivery within 24 hours (79.9% vs. 67.1%; RR 1.19; 95% CI 1.04-1.36). Early amniotomy compared with delayed amniotomy was associated with a shorter interval from oxytocin to delivery (WMD -1.5 hours; 95% CI -2.1 to -0.8), from Foley expulsion to vaginal delivery (WMD -2.5 hours; 95% CI -4.8 to -0.1), and from the start of oxytocin to vaginal delivery (WMD -1.8 hours; 95% CI -3.2 to -0.4). Other outcomes were not significantly different., Conclusion: Early amniotomy following cervical ripening by Foley balloon in individuals with singleton pregnancies did not impact rates of cesarean delivery compared with delayed amniotomy but led to shorter duration for various labor progress outcomes., (Copyright © 2024 Elsevier Inc.

Background: Cricoid pressure has been surrounded with controversies regarding its effectiveness. Application of ultrasound-guided para-laryngeal (PL) force has been shown to occlude the esophagus effectively compared with cricoid pressure (CP) in awake patients. We hypothesized that there would be no meaningful difference in the change in antero-posterior esophageal diameter from with application of cricoid or para-laryngeal pressure in parturients undergoing cesarean delivery under general anesthesia., Methods: In this prospective, randomized, non-inferiority trial, 40 parturients scheduled for elective cesarean delivery under general anesthesia were randomized to receive rapid sequence induction with either cricoid pressure (n = 20) or para-laryngeal pressure (n = 20). The antero-posterior diameter of the esophagus, measured by sonography, was the primary outcome. Visualization of the esophagus, its position in relation to the glottic aperture, esophageal occlusion, percentage of glottic opening (POGO), time to intubation, first pass success rate, overall success rate and adverse events like desaturation or bronchospasm were secondary outcomes., Results: The mean change in anterior-posterior diameter in the CP group was 0.17 ±0.1 cm vs. 0.28 ±0.1 cm in the PL group. The mean difference (CP-para-laryngeal pressure) between the groups was -0.11 (95% CI -0.17 to -0.1) cm. As the upper limit of the 95% CI was lower than the prespecified non-inferiority margin (δ = -0.2), non-inferiority was established (P <0.001]. There was no significant difference in the POGO score (P = 0.818), time to intubation (P =0.55), or intubation attempts (P = 0.99)., Conclusions: Para-laryngeal pressure was non-inferior to CP in occluding the esophagus in parturients undergoing cesarean delivery under general anesthesia and furthermore, no significant deterioration in intubation parameters was seen., (Copyright © 2024 Elsevier Ltd.

Objective: To compare the efficacy of foot reflexology and Benson's relaxation on anxiety and physiologic parameters after cesarean surgery., Design: Randomized controlled trial with three parallel arms., Setting: Gynecologic ward of the Persian Gulf Martyrs Hospital in Bushehr, Iran, in 2020., Participants and Interventions: Women undergoing cesarean surgery (n = 135) were selected by convenience sampling and divided via block randomization into three groups of foot reflexology, Benson's relaxation interventions, and control group (n = 45 in each group). Interventions were performed 2 hours after cesarean surgery., Measurements: Spielberger's State-Trait Anxiety Inventory, mercury sphygmomanometer, and pulse oximeter were used to collect the data. Anxiety was measured before and 30 minutes after the intervention. Physiologic parameters were measured before the intervention and immediately, 30 minutes, and 60 minutes after the intervention. Data were analyzed using inferential statistics., Results: The mean score of situational anxiety after the intervention was significantly lower than before the intervention in the reflexology (t = 6.171; 95% confidence interval [CI] [5.66, 11.14]) and Benson's relaxation groups (t = 7.362; 95% CI [5.91, 9.85]). However, changes in the control group were not significant (t = 1.674; 95% CI [-0.24, 2.55]). Decreases in anxiety scores were similar in the two intervention groups. After intervention, in most measurement times, respiratory rate and pulse rate decreased in the two intervention groups compared to the control group, and arterial oxygen saturation and systolic blood pressure increased., Conclusion: Considering the effect of both interventions on decreasing anxiety and improving most physiologic parameters, it seems that foot reflexology and Benson's relaxation can be recommended after cesarean surgery., (Copyright © 2024 AWHONN.
