Background: The prevalence and risk factors of posttraumatic stress disorder after cesarean delivery, outside high-risk contexts, remain unclear., Objective: This study aimed to assess posttraumatic stress disorder prevalence and risk factors at 2 months postpartum among a general population of women with cesarean delivery., Study Design: This was a prospective ancillary cohort study of the Tranexamic Acid for Preventing Postpartum Hemorrhage after Cesarean Delivery (TRAAP2) trial, conducted in 27 French hospitals from 2018 to 2020, enrolling women expected to undergo cesarean delivery before or during labor at ≥34 weeks of gestation. After randomization, characteristics of the cesarean delivery and postpartum blood loss were prospectively collected. Two months after childbirth, posttraumatic stress disorder profile (presence of posttraumatic stress disorder symptoms) and provisional diagnosis (positive screening for diagnosis consistent with a posttraumatic stress disorder) were assessed by 2 self-administered questionnaires (Impact of Event Scale - Revised and Traumatic Event Scale). The corrected posttraumatic stress disorder prevalence was estimated with inverse probability weighting to take nonresponse into account. Associations between potential risk factors and posttraumatic stress disorder were analyzed by multivariate logistic or linear regression modeling according to the type of dependent variable., Results: In total, 2785 of 4431 women returned the Impact of Event Scale - Revised questionnaire and 2792 the Traumatic Event Scale (response rates of 62.9% and 63.0%). The prevalence of posttraumatic stress disorder profile was 9.0% (95% confidence interval, 7.8%-10.3%) and of provisional diagnosis 1.7% (95% confidence interval, 1.2%-2.4%). Characteristics associated with a higher risk of posttraumatic stress disorder profile were prepregnancy vulnerability factors (young age, high body mass index, and African-born migrant) and cesarean delivery-related obstetrical factors (cesarean delivery after induced labor [adjusted odds ratio, 1.81; 95% confidence interval, 1.14-2.87], postpartum hemorrhage [adjusted odds ratio, 1.61; 95% confidence interval, 1.04-2.46] and high-intensity pain during the postpartum stay [adjusted odds ratio, 1.90; 95% confidence interval, 1.17-3.11]). Women who had immediate skin-to-skin contact with their newborn were at lower risk of posttraumatic stress disorder (adjusted odds ratio, 0.66; 95% confidence interval, 0.46-0.98), and women with bad memories of delivery on day 2 postpartum were at higher risk (adjusted odds ratio, 3.20; 95% confidence interval, 1.97-5.12). The Impact of Event Scale - Revised and the Traumatic Event Scale yielded consistent results., Conclusion: Approximately 1 in 11 women with cesarean deliveries had posttraumatic stress disorder symptoms at 2 months postpartum. Some obstetrical interventions and components of cesarean delivery management may influence this risk., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Background: The prevalence and risk factors of postpartum depression after cesarean delivery remain unclear., Objective: To assess the prevalence of postpartum depression and its risk factors 2 months after cesarean delivery., Methods: Prospective ancillary cohort study of the Tranexamic Acid for Preventing Postpartum Hemorrhage after Cesarean Delivery (TRAAP2) trial, conducted in 27 French hospitals in 2018-2020 and enrolling women undergoing cesarean delivery before or during labor at 34 or more weeks of gestation. After randomization, characteristics of the cesarean delivery, postpartum blood loss, and immediate postpartum period, including memories of delivery and postoperative pain, were prospectively collected. Women's characteristics, particularly any psychiatric history, were collected from medical records. Two months after childbirth, a postpartum depression provisional diagnosis was defined as a score of 13 or higher on the Edinburgh Postnatal Depression Scale, a validated self-administered questionnaire. The corrected prevalence of postpartum depression was calculated with the inverse probability weighting method to take nonrespondents into account. Multivariate logistic regression analyzed associations between potential risk factors and postpartum depression. A sensitivity analysis used an EPDS cutoff value of 11 or higher., Results: The questionnaire was returned by 2793/4431 women (63.0% response rate). The corrected prevalence of postpartum depression provisional diagnosis was 16.4% (95% confidence interval (CI), 14.9-18.0%) with an EPDS score of 13 or higher and 23.1% (95%CI, 21.4-24.9%) with a cutoff value of 11 or higher. Characteristics associated with a higher risk of postpartum depression were pre-pregnancy characteristics such as young age (aOR 0.83, 95%CI 0.74-0.93 for each 5-year increase in maternal age) and non-European country of birth (aOR 2.58, 95%CI 1.85-3.59 for North Africa; aOR 1.57, 95%CI 1.09-2.26 for Sub-Saharan Africa and aOR 1.99, 95%CI 1.28-3.10 for other country of birth; reference: Europe) and some aspects of the cesarean delivery, notably its timing and context, emergency before labor (aOR 1.70, 95%CI 1.15-2.50; reference: before labor without emergency) and during labor after induction of labor (aOR 1.36, 95%CI 1.03-1.84; reference: before labor without emergency). Also at higher risk were women reporting high intensity pain during the postpartum stay (aOR 1.73, 95%CI 1.32-2.26) and bad memories of delivery on day 2 postpartum (aOR 1.67, 95%CI 1.14-2.45). Conversely, women who had social support in the operating room had a lower risk of postpartum depression (aOR 0.73, 95%CI 0.53-0.97)., Conclusion: Around one woman in six had postpartum depression symptoms 2 months after cesarean delivery. Some cesarean-related obstetric factors may increase this risk: cesareans before labor for emergency situations or during labor after medically indicated induction of labor, severe postoperative pain and bad memories of delivery before discharge. Specific subgroups of at-risk women could benefit from early screening or intervention to reduce the onset of postpartum depression. Perinatal professionals should pay particular attention to postoperative pain management., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Background: Postpartum hemorrhage is the leading cause of maternal mortality worldwide. Quantitative blood loss assessment during cesarean delivery is a more accurate measure of blood loss than simple estimation. Risk factors for postpartum hemorrhage are well described. However, contemporary systematic investigations on the effect of indications for cesarean delivery on quantitative blood loss are lacking., Objective: This study aimed to investigate whether there are clinically significant differences in quantitative blood loss and postpartum hemorrhage risk based on the indication for cesarean delivery., Study Design: A total of 4881 cesarean deliveries performed at a large academic hospital between 2020 and 2022 were identified. Primary and repeat cesarean deliveries were analyzed separately and further subdivided into 7 indications: elective, labor arrest, fetal heart rate abnormalities, placenta previa, placenta accreta, malpresentation, and other. Quantitative blood loss and rates of postpartum hemorrhage (>1000 and >1500 mL) were compared among the different indications., Results: The mean quantitative blood loss estimates for primary, repeat, and total cesarean deliveries were 886, 697, and 792 mL, respectively. Excluding cases of placenta accreta, the greatest blood loss in both primary and repeat groups was observed in cesarean deliveries performed for labor arrest, with blood loss exceeding 1500 mL in 18% and 13% of all cases. Blood loss exceeding 1500 mL was noted in 1% and 2% of elective cesarean deliveries. The mean blood loss for planned repeat cesarean deliveries/hysterectomies for placenta accreta was <400 mL greater than that for primary cesarean deliveries performed for labor arrest (1442 vs 1065 mL, respectively), despite the addition of an often-complex hysterectomy to the procedure., Conclusion: Clinically and statistically significant differences in blood loss exist based on the indication for cesarean delivery. Large differences in the rates of serious postpartum hemorrhage (>1500 mL) with negligible differences in mean quantitative blood loss suggest the presence of frequent, large clinical outliers not reflected in a statistical mean. The indication for cesarean delivery and the possibility of such outliers rather than the predicted "average blood loss for cesarean delivery" should be considered when determining risk and the degree of necessary preoperative blood preparation. These data raise questions about whether current traditional techniques of cesarean delivery not associated with placenta accreta can be justified in nonemergent cases when such procedures can be performed with significantly less blood loss using techniques specific for placenta accreta., (Copyright © 2024 Elsevier Inc.

Objective: This study aimed (1) to assess the association between the length of the third stage of labor and adverse maternal outcome after vaginal birth and (2) to evaluate whether earlier manual placenta removal reduces the risk of adverse outcome., Data Sources: PubMed, MEDLINE, Embase, ClinicalTrials.gov, the Cochrane Library, Journals@Ovid, and the World Health Organization International Clinical Trials Registry were searched from January 1, 2000, to June 13, 2023., Study Eligibility Criteria: All studies that assessed adverse maternal outcome, defined as any maternal complication after vaginal birth, concerning the length of the third stage of labor and the timing of manual placenta removal were included., Methods: The included studies were evaluated using the Conducting Systematic Reviews and Meta-Analyses of Observational Studies of Etiology methodology. Pooled odds ratios with 95% confidence intervals were calculated. Heterogeneity (I 2 test) was assessed, subgroup analyses were performed, and 95% prediction intervals were calculated., Results: To meet the first objective, 18 cohort studies were included. The assessed cutoff values for the length of the third stage of labor were 15, 30, and 60 minutes. Women with a third stage of labor of ≥15 minutes had an increased risk of postpartum hemorrhage compared with those with a third stage of labor of <15 minutes (odds ratio, 5.55; 95% confidence interval, 1.74-17.72). For women without risk factors for postpartum hemorrhage, the odds ratio was 2.20 (95% confidence interval, 0.75-6.49). Among women with a third stage of labor of ≥60 minutes vs women with a third stage of labor of <60 minutes, the odds ratio was 3.72 (95% confidence interval, 2.36-5.89). The incidence of red blood cell transfusion was higher for a third stage of labor of ≥30 minutes than for a third stage of labor of <30 minutes (odds ratio, 3.23; 95% confidence interval, 2.26-4.61). Of note, 3 studies assessed the timing of placenta removal and the risk of adverse maternal outcome. However, the results could not be pooled because of the different outcome measures. Moreover, 1 randomized controlled trial (RCT) reported a significantly higher incidence of hemodynamic compromise in women with manual placenta removal at 15 minutes than in women with manual placenta removal at 10 minutes (30/156 [19.2%] vs 10/156 [6.4%], respectively), whereas 2 observational studies reported a lower risk of bleeding among women without manual placenta removal., Conclusion: Although the risk of adverse maternal outcome after vaginal birth increases when the third stage of labor exceeds 15 minutes, there is no convincing supporting evidence that reducing the length of the third stage of labor by earlier manual removal of the placenta can reduce the incidence of adverse maternal outcome., (Copyright © 2024 The Author(s).

ObjectiveRegulatory bodies and insurers evaluate hospital quality using obstetrical outcomes, however meaningful comparisons should take preexisting patient characteristics into account. Furthermore, if risk-adjusted outcomes are consistent within a hospital, fewer measures and resources would be needed to assess obstetrical quality. Our objective was to establish risk-adjusted models for 5 obstetric outcomes and assess hospital performance across these outcomes.Study designWe studied a cohort of 115,502 women and their neonates born in 25 hospitals in the United States from March 2008 through February 2011. Hospitals were ranked according to their unadjusted and risk-adjusted frequency of venous thromboembolism, postpartum hemorrhage, peripartum infection, severe perineal laceration, and a composite neonatal adverse outcome. Correlations between hospital risk-adjusted outcome frequencies were assessed.ResultsVenous thromboembolism occurred too infrequently (0.03%; 95% confidence interval [CI], 0.02-0.04%) for meaningful assessment. Other outcomes occurred frequently enough for assessment (postpartum hemorrhage, 2.29%; 95% CI, 2.20-2.38, peripartum infection, 5.06%; 95% CI, 4.93-5.19, severe perineal laceration at spontaneous vaginal delivery, 2.16%; 95% CI, 2.06-2.27, neonatal composite, 2.73%; 95% CI, 2.63-2.84). Although there was high concordance between unadjusted and adjusted hospital rankings, several individual hospitals had an adjusted rank that was substantially different (as much as 12 rank tiers) than their unadjusted rank. None of the correlations between hospital-adjusted outcome frequencies was significant. For example, the hospital with the lowest adjusted frequency of peripartum infection had the highest adjusted frequency of severe perineal laceration.ConclusionEvaluations based on a single risk-adjusted outcome cannot be generalized to overall hospital obstetric performance.

Background: Postpartum hemorrhage is difficult to predict, is associated with significant maternal morbidity, and is the leading cause of maternal mortality worldwide. The identification of maternal biomarkers that can predict increased postpartum hemorrhage risk would enhance clinical care and may uncover mechanisms that lead to postpartum hemorrhage., Objective: This retrospective case-control study employed agnostic proteomic profiling of maternal plasma samples to identify differentially abundant proteins in controls and postpartum hemorrhage cases., Study Design: Maternal plasma samples were procured from a cohort of >60,000 participants in a single institution's perinatal repository. Postpartum hemorrhage was defined as a decrease in hematocrit of ≥10% or receipt of transfusion within 24 hours after delivery. Postpartum hemorrhage cases (n=30) were matched by maternal age and delivery mode (vaginal or cesarean) with controls (n=56). Mass spectrometry was used to identify differentially abundant proteins using integrated peptide peak areas. Statistically significant differences between groups were defined as P<.05 after controlling for multiple comparisons., Results: By study design, cases and controls did not differ in race, ethnicity, gestational age at delivery, blood type, or predelivery platelet count. Cases had slightly but significantly lower predelivery and postdelivery hematocrit and hemoglobin. Mass spectrometry detected 1140 proteins, including 77 proteins for which relative abundance differed significantly between cases and controls (fold change >1.15, P<.05). Of these differentially abundant plasma proteins, most had likely liver or placental origins. Gene ontology term analysis mapped to protein clusters involved in responses to wound healing, stress response, and host immune defense. Significantly differentially abundant proteins with the highest fold change (prostaglandin D2 synthase, periostin, and several serine protease inhibitors) did not correlate with predelivery hematocrit or hemoglobin but identified postpartum hemorrhage cases with logistic regression modeling revealing good-to-excellent area under the operator receiver characteristic curves (0.802-0.874). Incorporating predelivery hemoglobin with these candidate proteins further improved the identification of postpartum hemorrhage cases., Conclusion: Agnostic analysis of maternal plasma samples identified differentially abundant proteins in controls and postpartum hemorrhage cases. Several of these proteins are known to participate in biologically plausible pathways for postpartum hemorrhage risk and have potential value for predicting postpartum hemorrhage. These findings identify candidate protein biomarkers for future validation and mechanistic studies., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Background: The optimal timing of amniotomy during labor induction is a topic of ongoing debate due to the potential risks associated with both amniotomy and prolonged labor. As such, individuals in the field of obstetrics and gynecology must carefully evaluate the associated benefits and drawbacks of this procedure. While amniotomy can expedite the labor process, it may also lead to complications such as umbilical cord prolapse, fetal distress, and infection. Therefore, a careful and thorough examination of the risks and benefits of amniotomy during labor induction is essential in making an informed decision regarding the optimal timing of this procedure., Objective: This study aimed to determine if an amniotomy within 2 hours after Foley balloon removal reduced the duration of active labor and time taken to achieve vaginal delivery when compared with an amniotomy ≥4 hours after balloon removal among term pregnant women who underwent labor induction., Study Design: This was an open-label, randomized controlled trial that was conducted at a single academic center from October 2020 to March 2023. Term participants who were eligible for preinduction cervical ripening with a Foley balloon were randomized into 2 groups, namely the early amniotomy (rupture of membranes within 2 hours after Foley balloon removal) and delayed amniotomy (rupture of membranes performed more than 4 hours after Foley balloon removal) groups. Randomization was stratified by parity. The primary outcome was time from Foley balloon insertion to active phase of labor. Secondary outcomes, including time to delivery, cesarean delivery rates, and maternal and neonatal complications, were analyzed using intention-to-treat and per-protocol analyses., Results: Of the 150 participants who consented and were enrolled, 149 were included in the analysis. In the intention-to-treat population, an early amniotomy did not significantly shorten the time between Foley balloon insertion and active labor when compared with a delayed amniotomy (885 vs 975 minutes; P=.08). An early amniotomy was associated with a significantly shorter time from Foley balloon placement to active labor in nulliparous individuals (1211; 584-2340 vs 1585; 683-2760; P=.02). When evaluating the secondary outcomes, an early amniotomy was associated with a significantly shorter time to active labor onset (312.5 vs 442.5 minutes; P=.02) and delivery (484 vs 587 minutes; P=.03) from Foley balloon removal with a higher rate of delivery within 36 hours (96% vs 85%; P=.03). Individuals in the early amniotomy group reached active labor 1.5 times faster after Foley balloon insertion than those in the delayed group (hazard ratio, 1.5; 95% confidence interval, 1.1-2.2; P=.02). Those with an early amniotomy also reached vaginal delivery 1.5 times faster after Foley balloon removal than those in the delayed group (hazard ratio, 1.5; 95% confidence interval, 1-2.2; P=.03). A delayed amniotomy was associated with a higher rate of postpartum hemorrhage (0% vs 9.5%; P=.01). No significant differences were observed in the cesarean delivery rates, length of hospital stay, maternal infection, or neonatal outcomes., Conclusion: Although an early amniotomy does not shorten the time from Foley balloon insertion to active labor, it shortens time from Foley balloon removal to active labor and delivery without increasing complications. The increased postpartum hemorrhage rate in the delayed amniotomy group suggests increased risks with delayed amniotomy., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Background: Standardization of procedures improves outcomes. Though systematic reviews have summarized the evidence-based steps (EBS) of cesarean delivery (CD), their bundled implementation has not been investigated., Objective: In this pre- and post-implementation trial, we sought to ascertain if bundled EBS of CD, compared to surgeon's preference, improves outcomes., Study Design: A StaRI (Standards for Reporting Implementation Studies) compliant, multi-center pre- and post-implementation trial at 4 teaching hospitals was conducted. The pre-implementation period consisted of CD done based on the physicians' preferences for 3 months; educational intervention (e.g., didactics, badge cards, posters, video) occurred at the 4 th month. CDs in post-implementation period employed the bundled EBS. A pre-planned 10% randomized audit of both groups assessed adherence and uptake of EBS. The primary outcome was a composite maternal morbidity (CMM), which included estimated blood loss > 1,000 mL, blood transfusion, endometritis, post-partum fever, wound complications, sepsis, thrombosis, ICU admission, hysterectomy, or death. The secondary outcome was a composite neonatal morbidity (CNM) and some of its components were 5-min Apgar score < 7, positive pressure oxygen use, hypoglycemia, or sepsis. A priori Bayesian sample size calculation indicated 700 CD in each group was needed to demonstrate 20% relative reduction (from 15% to 12%) of CMM with 75% certainty. Bayesian logistic regression with neutral priors was used to calculate likelihood of net-improvement in adjusted relative risk (aRR) with 95% credible intervals (CrI)., Results: A total of 1,425 consecutive CD (721 in pre- and 704 in post-implementation group) were examined. Audited data indicated that the baseline EBS utilization rate during the pre-implementation period was 79%; after the implementation bundled EBS of CD the audited adherence was 89%-an uptake of 10.0% of the EBS. In four aspects, the maternal characteristics differed significantly in the pre- and post-implementation periods: race/ethnicity, hypertensive disorder, and the relative contribution of the 4 centers to the cohorts and the gestational age at delivery, but the indications for CD and whether its duration was < versus > 60 min did not. The rates of CMM in the pre- and post-implementation groups were 26% and 22%, respectively (aRR, 0.88; 95% CrI, 0.73-1.04), with a 94 % Bayesian probability of a reduction in CMM. The CNM occurred in 37% of the pre- and in 41% of the post-implementation group (aRR, 1.12; 95% CrI 0.98-1.39), with a 95% Bayesian probability of worsening in CNM. When CMM were segregated by preterm (<37 wks) and term (> 37 weeks) CD, the improvement in maternal outcomes persisted; when CNM were segregated by gestational age subgroupsthe potential for worsening neonatal outcomes persisted as well., Conclusions: Standardization of the evidence-based bundled steps of cesarean delivery resulted in a modest reduction of the composite maternal outcome; however, a paradoxical increase in neonatal composite morbidity was noted. Although individual evidence-based steps may be of value, while awaiting additional intervention trials a formal bundling of such steps is currently not recommended., (Copyright © 2024.

The third stage of labor is defined as the time period between delivery of the fetus through delivery of the placenta. During a normal third stage, uterine contractions lead to separation and expulsion of the placenta from the uterus. Postpartum hemorrhage is a relatively common complication of the third stage of labor. Strategies have been studied to mitigate the risk of postpartum hemorrhage, leading to the widespread implementation of active management of the third stage of labor. Initially, active management of the third stage of labor consisted of a bundle of interventions including administration of a uterotonic agent, early cord clamping, controlled cord traction, and external uterine massage. However, the effectiveness of these interventions as a bundle has been questioned, leading to abandonment of some components in recent years. Despite this, upon review of selected international guidelines, we found that the term "active management of the third stage of labor" was still used, but recommendations for and against individual interventions were variable and not necessarily supported by current evidence. In this review, we: (1) examine the physiology of the third stage of labor, (2) present evidence related to interventions that prevent postpartum hemorrhage and promote maternal and neonatal health, (3) review current global guidelines and recommendations for practice, and (4) propose future areas of investigation. The interventions in this review include pharmacologic agents to prevent postpartum hemorrhage, cord clamping, cord milking, cord traction, cord drainage, early skin-to-skin contact, and nipple stimulation. Treatment of complications of the third stage of labor is outside of the scope of this review. We conclude that current evidence supports the use of effective pharmacologic postpartum hemorrhage prophylaxis, delayed cord clamping, early skin-to-skin contact, and controlled cord traction at delivery when feasible. The most effective uterotonic regimens for preventing postpartum hemorrhage after vaginal delivery include oxytocin plus ergometrine; oxytocin plus misoprostol; or carbetocin. After cesarean delivery, carbetocin or oxytocin as a bolus are the most effective regimens. There is inconsistent evidence regarding the use of tranexamic acid in addition to a uterotonic compared with a uterotonic alone for postpartum hemorrhage prevention after all deliveries. Because of differences in patient comorbidities, costs, and availability of resources and staff, decisions to use specific prevention strategies are dependent on patient- and system-level factors. We recommend that the term "active management of the third stage of labor" as a combined intervention no longer be used. Instead, we recommend that "third stage care" be adopted, which promotes the implementation of evidence-based interventions that incorporate practices that are safe and beneficial for both the woman and neonate., (Copyright © 2022 Elsevier Inc.

Clinical chorioamnionitis, the most common infection-related diagnosis in labor and delivery units, is an antecedent of puerperal infection and neonatal sepsis. The condition is suspected when intrapartum fever is associated with two other maternal and fetal signs of local or systemic inflammation (eg, maternal tachycardia, uterine tenderness, maternal leukocytosis, malodorous vaginal discharge or amniotic fluid, and fetal tachycardia). Clinical chorioamnionitis is a syndrome caused by intraamniotic infection, sterile intraamniotic inflammation (inflammation without bacteria), or systemic maternal inflammation induced by epidural analgesia. In cases of uncertainty, a definitive diagnosis can be made by analyzing amniotic fluid with methods to detect bacteria (Gram stain, culture, or microbial nucleic acid) and inflammation (white blood cell count, glucose concentration, interleukin-6, interleukin-8, matrix metalloproteinase-8). The most common microorganisms are Ureaplasma species, and polymicrobial infections occur in 70% of cases. The fetal attack rate is low, and the rate of positive neonatal blood cultures ranges between 0.2% and 4%. Intrapartum antibiotic administration is the standard treatment to reduce neonatal sepsis. Treatment with ampicillin and gentamicin have been recommended by professional societies, although other antibiotic regimens, eg, cephalosporins, have been used. Given the importance of Ureaplasma species as a cause of intraamniotic infection, consideration needs to be given to the administration of antimicrobial agents effective against these microorganisms such as azithromycin or clarithromycin. We have used the combination of ceftriaxone, clarithromycin, and metronidazole, which has been shown to eradicate intraamniotic infection with microbiologic studies. Routine testing of neonates born to affected mothers for genital mycoplasmas could improve the detection of neonatal sepsis. Clinical chorioamnionitis is associated with decreased uterine activity, failure to progress in labor, and postpartum hemorrhage; however, clinical chorioamnionitis by itself is not an indication for cesarean delivery. Oxytocin is often administered for labor augmentation, and it is prudent to have uterotonic agents at hand to manage postpartum hemorrhage. Infants born to mothers with clinical chorioamnionitis near term are at risk for early-onset neonatal sepsis and for long-term disability such as cerebral palsy. A frontier is the noninvasive assessment of amniotic fluid to diagnose intraamniotic inflammation with a transcervical amniotic fluid collector and a rapid bedside test for IL-8 for patients with ruptured membranes. This approach promises to improve diagnostic accuracy and to provide a basis for antimicrobial administration., (Published by Elsevier Inc.)

Background: The effect on obstetrical outcomes of closed- or open-glottis pushing is uncertain among both nulliparous and parous women., Objective: This study aimed to assess the association between open- or closed-glottis pushing and mode of delivery after an attempted singleton vaginal birth at or near term., Study Design: This was an ancillary planned cohort study of the TRAAP (TRAnexamic Acid for Preventing postpartum hemorrhage after vaginal delivery) randomized controlled trial, conducted in 15 French maternity units from 2015 to 2016 that enrolled women with an attempted singleton vaginal delivery after 35 weeks' gestation. After randomization, characteristics of labor and delivery were prospectively collected, with special attention to active second-stage pushing and a specific planned questionnaire completed immediately after birth by the attending care provider. The exposure was the mode of pushing, classified into 2 groups: closed- or open-glottis. The main endpoint was operative vaginal delivery. Secondary endpoints were items of maternal morbidity, including severe perineal laceration, episiotomy, postpartum hemorrhage, duration of the second stage of labor, and a composite severe neonatal morbidity outcome. We also assessed immediate maternal satisfaction, experience of delivery, and psychological status 2 months after delivery. The associations between mode of pushing and outcome were analyzed by multivariate logistic regression to control for confounding bias, with multilevel mixed-effects analysis, and a random intercept for center., Results: Among 3041 women included in our main analysis, 2463 (81.0%) used closed-glottis pushing and 578 (19.0%) open-glottis pushing; their respective operative vaginal delivery rates were 19.1% (n=471; 95% confidence interval, 17.6-20.7) and 12.5% (n=72; 95% confidence interval, 9.9-15.4; P<.001). In an analysis stratified according to parity and after controlling for available confounders, the rate of operative vaginal delivery did not differ between the groups among nulliparous women: 28.7% (n=399) for the closed-glottis and 27.5% (n=64) for the open-glottis group (adjusted odds ratio, 0.93; 95% confidence interval, 0.65-1.33; P=.7). The operative vaginal delivery rate was significantly lower for women using open- compared with closed-glottis pushing in the parous population: 2.3% (n=8) for the open- and 6.7% (n=72) for the closed-glottis groups (adjusted odds ratio, 0.43; 95% confidence interval, 0.19-0.90; P=.03). Other maternal and neonatal outcomes did not differ between the 2 modes of pushing among either the nulliparous or parous groups., Conclusion: Among nulliparous women with singleton pregnancies at term, the risk of operative vaginal birth did not differ according to mode of pushing. These results will inform shared decision-making about the mode of pushing during the second stage of labor., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Postpartum hemorrhage remains a major cause of maternal mortality and morbidity worldwide with higher rates found in resource-challenged countries. Conventional use of uterotonics such as oxytocin, prostaglandins, and medications to support coagulation, such as fibrinogen and tranexamic acid, are helpful but may not be sufficient to arrest life-threatening postpartum hemorrhage. Severe postpartum hemorrhage leads to an increased need for blood transfusions and the use of invasive techniques, such as intrauterine balloon tamponade, compression sutures, and arterial ligation, as advanced steps in the management cascade. In extreme cases where hemorrhage is resistant to these therapies, a hysterectomy may be necessary to avoid possible maternal death. Uterine packing with a chitosan-covered tamponade is an emerging tool in the armamentarium of the obstetrical team, especially when resources for advance surgical and other invasive options may be limited. Modified chitosan-impregnated gauze was originally described in the management of acute hemorrhage in the field of military medicine, combining the physiological antihemorrhaging effect of modified chitosan with a compression tamponade for the acute treatment of wound bleeding. The first described use in obstetrics was in 2012, showing that the chitosan-covered tamponade is an effective intervention to arrest ongoing therapy-resistant postpartum hemorrhage. Further studies showed a reduction in hysterectomies and blood transfusions. The method is, however, underreported and is not yet an established method used worldwide. To demonstrate the step-by-step application of the intrauterine chitosan-covered tamponade in the management of therapy-resistant postpartum hemorrhage, we have produced a teaching video to illustrate the important steps and techniques to optimize the effectiveness and safety of this novel intervention., (Copyright © 2022 Elsevier Inc.

Background: Very little is known about the prevalence and risk factors of postpartum depression among women with vaginal births without major pregnancy complications., Objective: This study aimed to assess the prevalence of postpartum depression and identify its characteristics 2 months after singleton vaginal delivery at or near term., Study Design: This was an ancillary cohort study of the TRanexamic Acid for Preventing Postpartum Hemorrhage After Vaginal Delivery randomized controlled trial, which was conducted in 15 French hospitals in 2015-2016 and enrolled women with singleton vaginal deliveries after 35 weeks of gestation. After randomization, the characteristics of labor, delivery, and the immediate postpartum experience, including the experience of childbirth, were prospectively collected. Medical records provided women's other characteristics, particularly any psychiatric history. Of note, 2 months after childbirth, provisional postpartum depression diagnosis was defined as a score of ≥13 on the Edinburgh Postnatal Depression Scale, a validated self-administered questionnaire. The corrected prevalence of postpartum depression was calculated with the inverse probability weighting method to take nonrespondents into account. Associations between potential risk factors and postpartum depression were analyzed by multivariate logistic regression. Moreover, an Edinburgh Postnatal Depression Scale cutoff value of ≥11 was selected to perform a sensitivity analysis., Results: The questionnaire was returned by 2811 of 3891 women (72.2% response rate). The prevalence rates of the provisional diagnosis were 9.9% (95% confidence interval, 8.6%-11.3%) defined by an Edinburgh Postnatal Depression Scale score of ≥13 and 15.5% (95% confidence interval, 14.0%-17.1%) with a cutoff value of ≥11. The characteristics associated with higher risks of postpartum depression in multivariate analysis were mostly related to prepregnancy characteristics, specifically age of <25 years (adjusted odds ratio, 1.8; 95% confidence interval, 1.1-2.9) and advanced age (adjusted odds ratio, 1.8; 95% confidence interval, 1.2-2.6), migration from North Africa (adjusted odds ratio, 2.9; 95% confidence interval, 1.9-4.4), previous abortion (adjusted odds ratio, 1.4; 95% confidence interval, 1.0-2.0), and psychiatric history (adjusted odds ratio, 2.9; 95% confidence interval, 1.8-4.8). Some characteristics of labor and delivery, such as induced labor (adjusted odds ratio, 1.5; 95% confidence interval, 1.1-2.0) and operative vaginal delivery (adjusted odds ratio, 1.4; 95% confidence interval, 1.0-2.0), seemed to be associated with postpartum depression. In addition, bad memories of childbirth in the immediate postpartum were strongly associated with postpartum depression symptoms at 2 months after giving birth (adjusted odds ratio, 2.4; 95% confidence interval, 1.3-4.2)., Conclusion: Approximately 10% of women with vaginal deliveries have postpartum depression symptoms, assessed by a score of ≥13 on the depression scale that was used at 2 months. Prepregnancy vulnerability factors; obstetrical characteristics, such as induced labor and operative vaginal delivery; and bad memories of childbirth 2 days after delivery were the main factors associated with this provisional diagnosis. A screening approach that targets risk factors may help to identify women at risk of postpartum depression who could benefit from early intervention., (Copyright © 2023 Elsevier Inc.

Objective: This systematic review and meta-analysis aimed to conduct a thorough and contemporary assessment of maternal and neonatal outcomes associated with water birth in comparison with land-based birth., Data Sources: We conducted a comprehensive search of PubMed, EMBASE, CINAHL, and gray literature sources, from inception to February 28, 2023., Study Eligibility Criteria: We included randomized and nonrandomized studies that assessed maternal and neonatal outcomes in patients who delivered either conventionally or while submerged in water., Methods: Pooled unadjusted odds ratios with 95% confidence intervals were calculated using a random-effects model (restricted maximum likelihood method). We assessed the 95% prediction intervals to estimate the likely range of future study results. To evaluate the robustness of the results, we calculated fragility indices. Maternal infection was designated as the primary outcome, whereas postpartum hemorrhage, perineal lacerations, obstetrical anal sphincter injury, umbilical cord avulsion, low Apgar scores, neonatal aspiration requiring resuscitation, neonatal infection, neonatal mortality within 30 days of birth, and neonatal intensive care unit admission were considered secondary outcomes., Results: Of the 20,642 articles identified, 52 were included in the meta-analyses. Based on data from observational studies, water birth was not associated with increased probability of maternal infection compared with land birth (10 articles, 113,395 pregnancies; odds ratio, 0.93; 95% confidence interval, 0.76-1.14). Patients undergoing water birth had decreased odds of postpartum hemorrhage (21 articles, 149,732 pregnancies; odds ratio, 0.80; 95% confidence interval, 0.68-0.94). Neonates delivered while submerged in water had increased odds of cord avulsion (10 articles, 91,504 pregnancies; odds ratio, 1.75; 95% confidence interval, 1.38-2.24) and decreased odds of low Apgar scores (21 articles, 165,917 pregnancies; odds ratio, 0.69; 95% confidence interval, 0.58-0.82), neonatal infection (15 articles, 53,635 pregnancies; odds ratio, 0.64; 95% confidence interval, 0.42-0.97), neonatal aspiration requiring resuscitation (19 articles, 181,001 pregnancies; odds ratio, 0.60; 95% confidence interval, 0.43-0.84), and neonatal intensive care unit admission (30 articles, 287,698 pregnancies; odds ratio, 0.56; 95% confidence interval, 0.45-0.70)., Conclusion: When compared with land birth, water birth does not appear to increase the risk of most maternal and neonatal complications. Like any other delivery method, water birth has its unique considerations and potential risks, which health care providers and expectant parents should evaluate thoroughly. However, with proper precautions in place, water birth can be a reasonable choice for mothers and newborns, in facilities equipped to conduct water births safely., (Copyright © 2023 Elsevier Inc.

Postpartum hemorrhage remains one of the principal causes of maternal mortality in the United States and throughout the world. Its management, which must be multidisciplinary (obstetrics, midwifery, anesthesiology, interventional radiology, and nursing), depends on the speed of both diagnosis and implementation of medical and surgical treatment to control the hemorrhage. The aim of this work is to describe the various techniques of vessel ligation and of uterine compression for controlling and treating severe hemorrhage, and to present the advantages and disadvantages of each. It is not difficult to perform vessel ligation of the uterine arteries: O'Leary's bilateral ligation of the uterine artery, Tsirulnikov's triple ligation, and AbdRabbo's stepwise uterine devascularization (that is, stepwise triple ligation). These procedures are associated with a high success rate (approximately 90%) and a low complication rate. Bilateral ligation of the internal iliac (hypogastric) arteries is more difficult to perform and potentially less effective (approximately 70% effectiveness) than the previously mentioned procedures. Its complication rate is low, but the complications are most often serious. There is no evidence that future fertility or subsequent obstetrical outcomes are impaired by ligation of either the uterine or internal iliac arteries. There are many techniques used for uterine compression sutures, and none has shown clear superiority to another. Uterine compression suture has an effectiveness rate of approximately 75% after failure of medical treatment and approximately 80% as a second-line procedure after unsuccessful vessel ligation. The risk of synechiae after uterine compression suture has not yet been adequately evaluated, but is probably around 5%. The risk of synechiae after uterine compression suture has not yet been adequately evaluated, but probably ranges between 5% and 10%. The methodologic quality of the studies assessing uterine-sparing surgical procedures remains limited, with no comparative studies. Accordingly, no evidence suggests that any one of these methods is better than any other. Accordingly, the choice of surgical technique to control hemorrhage must be guided firstly by the operator's experience. If the hemorrhage continues after a first-line uterine-sparing surgical procedure and the patient remains hemodynamically stable, a second-line procedure can be chosen. Nonetheless, the application of these procedures must not delay the performance of a peripartum hysterectomy in cases of hemodynamic instability., (Copyright © 2022 Elsevier Inc.

Oxytocin is a peptide hormone that plays a key role in regulating the female reproductive system, including during labor and lactation. It is produced primarily in the hypothalamus and secreted by the posterior pituitary gland. Oxytocin can also be administered as a medication to initiate or augment uterine contractions. To study the effectiveness and safety of oxytocin, previous studies have randomized patients to low- and high-dose oxytocin infusion protocols either alone or as part of an active management of labor strategy along with other interventions. These randomized trials demonstrated that active management of labor and high-dose oxytocin regimens can shorten the length of labor and reduce the incidence of clinical chorioamnionitis. The safety of high-dose oxytocin regimens is also supported by no associated differences in fetal heart rate abnormalities, postpartum hemorrhage, low Apgar scores, neonatal intensive care unit admissions, and umbilical artery acidemia. Most studies reported no differences in the cesarean delivery rates with active management of labor or high-dose oxytocin regimens, thereby further validating its safety. Oxytocin does not have a predictable dose response, thus the pharmacologic effects and the amplitude and frequency of uterine contractions are used as physiological parameters for oxytocin infusion titration to achieve adequate contractions at appropriate intervals. Used in error, oxytocin can cause patient harm, highlighting the importance of precise administration using infusion pumps, institutional safety checklists, and trained nursing staff to closely monitor uterine activity and fetal heart rate changes. In this review, we summarize the physiology, pharmacology, infusion regimens, and associated risks of oxytocin., (Copyright © 2023. Published by Elsevier Inc.)

Obstetrical hemorrhage is a relatively frequent obstetrical complication and a common cause of maternal morbidity and mortality worldwide. The majority of maternal deaths attributable to hemorrhage are preventable, thus, developing rapid and effective means of treating postpartum hemorrhage is of critical public health importance. Intrauterine devices are one option for managing refractory hemorrhage, with rapid expansion of available devices in recent years. Intrauterine packing was historically used for this purpose, with historical cohorts documenting high rates of success. Modern packing materials, including chitosan-covered gauze, have recently been explored with success rates comparable to uterine balloon tamponade in small trials. There are a variety of balloon tamponade devices, both commercial and improvised, available for use. Efficacy of 85.9% was cited in a recent meta-analysis in resolution of hemorrhage with the use of uterine balloon devices, with greatest success in the setting of atony. However, recent randomized trials have demonstrated potential harm associated with improvised balloon tamponade use In low resource settings and the World Health Organization recommends use be restricted to settings where monitoring is available and care escalation is possible. Recently, intrauterine vacuum devices have been introduced, which offer a new mechanism for achieving hemorrhage control by mechanically restoring uterine tone via vacuum suction. The Jada device, which is is FDA-cleared and commercially available in the US, found successful bleeding control in 94% of cases in an initial single-arm trial, with recent post marketing registry study described treatment success following hemorrhage in 95.8% of vaginal and 88.2% of cesarean births. Successful use of improvised vacuum devices has been described in several studies, including suction tube uterine tamponade via Levin tubing, and use of a modified Bakri balloon. Further research is needed with head-to-head comparisons of efficacy of devices and assessment of cost within the context of both device pricing and overall healthcare resource utilization., (Copyright © 2023 Elsevier Inc.

Background: Previous studies reported conflicting results on the relationship between oxytocin use for labor augmentation and the risk of postpartum hemorrhage, probably because it is rather challenging to disentangle oxytocin use from labor dystocia., Objective: This study aimed to investigate the independent association between oxytocin use for augmentation and the risk of postpartum hemorrhage by using advanced statistical modeling to control for labor patterns and other covariates., Study Design: We used data from 20,899 term, cephalic, singleton pregnancies of patients with spontaneous onset of labor and no previous cesarean delivery from Intermountain Healthcare in Utah in the Consortium on Safe Labor. Presence of postpartum hemorrhage was identified on the basis of a clinical diagnosis. Propensity scores were calculated using a generalized linear mixed model for oxytocin use for augmentation, and covariate balancing generalized propensity score was applied to obtain propensity scores for the duration and total dosage of oxytocin augmentation. A weighted generalized additive mixed model was used to depict dose-response curves between the duration and total dosage of oxytocin augmentation and the outcomes. The average treatment effects of oxytocin use for augmentation on postpartum hemorrhage and estimated blood loss (mL) were assessed by inverse probability weighting of propensity scores., Results: The odds of both postpartum hemorrhage and estimated blood loss increased modestly when the duration and/or total dosage of oxytocin used for augmentation increased. However, in comparison with women for whom oxytocin was not used, oxytocin augmentation was not clinically or statistically significantly associated with estimated blood loss (6.5 mL; 95% confidence interval, 2.5-10.3) or postpartum hemorrhage (adjusted odds ratio, 1.02; 95% confidence interval, 0.82-1.24) when rigorously controlling for labor pattern and potential confounders. The results remained consistent regardless of inclusion of women with an intrapartum cesarean delivery., Conclusion: The odds of postpartum hemorrhage and estimated blood loss increased modestly with increasing duration and total dosage of oxytocin augmentation. However, in comparison with women for whom oxytocin was not used and after controlling for potential confounders, there was no clinically significant association between oxytocin use for augmentation and estimated blood loss or the risk of postpartum hemorrhage., (Copyright © 2023 Elsevier Inc.

Placenta accreta spectrum is a life-threatening complication of pregnancy that is underdiagnosed and can result in massive hemorrhage, disseminated intravascular coagulation, massive transfusion, surgical injury, multisystem organ failure, and even death. Given the rarity and complexity, most obstetrical hospitals and providers do not have comprehensive expertise in the diagnosis and management of placenta accreta spectrum. Emergency management, antenatal interdisciplinary planning, and system preparedness are key pillars of care for this life-threatening disorder. We present an updated sample checklist for emergent and unplanned cases, an antenatal planning worksheet for known or suspected cases, and a bundle of activities to improve system and team preparedness for placenta accreta spectrum., (Copyright © 2023.

Background: Many questions remain about the appropriate use of intrauterine balloon devices in postpartum hemorrhage after vaginal delivery refractory to first-line uterotonics. Available data suggest that early use of intrauterine balloon tamponade might be beneficial., Objective: This study aimed to compare the effect of intrauterine balloon tamponade used in combination with second-line uterotonics vs intrauterine balloon tamponade used after the failure of second-line uterotonic treatment on the rate of severe postpartum hemorrhage in women with postpartum hemorrhage after vaginal delivery refractory to first-line uterotonics., Study Design: This multicenter, randomized, controlled, parallel-group, nonblinded trial was conducted at 18 hospitals and enrolled 403 women who had just given birth vaginally at 35 to 42 weeks of gestation. The inclusion criteria were a postpartum hemorrhage refractory to first-line uterotonics (oxytocin) and requiring a second-line uterotonic treatment with sulprostone (E1 prostaglandin). In the study group, the sulprostone infusion was combined with intrauterine tamponade by an ebb balloon performed within 15 minutes of randomization. In the control group, the sulprostone infusion was started alone within 15 minutes of randomization, and if bleeding persisted 30 minutes after the start of sulprostone infusion, intrauterine tamponade using the ebb balloon was performed. In both groups, if the bleeding persisted 30 minutes after the insertion of the balloon, an emergency radiological or surgical invasive procedure was performed. The primary outcome was the proportion of women who either received ≥3 units of packed red blood cells or had a calculated peripartum blood loss of >1000 mL. The prespecified secondary outcomes were the proportions of women who had a calculated blood loss of ≥1500 mL, any transfusion, an invasive procedure and women who were transferred to the intensive care unit. The analysis of the primary outcome with the triangular test was performed sequentially throughout the trial period., Results: At the eighth interim analysis, the independent data monitoring committee concluded that the incidence of the primary outcome did not differ between the 2 groups and stopped inclusions. After 11 women were excluded because they met an exclusion criterion or withdrew their consent, 199 and 193 women remained in the study and control groups, respectively, for the intention-to-treat analysis. The women's baseline characteristics were similar in both groups. Peripartum hematocrit level change, which was needed for the calculation of the primary outcome, was missing for 4 women in the study group and 2 women in the control group. The primary outcome occurred in 131 of 195 women (67.2%) in the study group and 142 of 191 women (74.3%) in the control group (risk ratio, 0.90; 95% confidence interval, 0.79-1.03). The groups did not differ substantially for rates of calculated peripartum blood loss pf ≥1500 mL, any transfusion, invasive procedure, and admission to an intensive care unit. Endometritis occurred in 5 women (2.7%) in the study group and none in the control group (P=.06)., Conclusion: The early use of intrauterine balloon tamponade did not reduce the incidence of severe postpartum hemorrhage compared with its use after the failure of second-line uterotonic treatment and before recourse to invasive procedures., (Copyright © 2023 Elsevier Inc.

Background: Placenta accreta spectrum disorders are a continuum of placental pathologies with significant maternal morbidity and mortality. Morbidity is related to the overall degree of placental adherence, and thus patients with placenta increta or percreta represent a high-risk category of patients. Hemorrhage and transfusion of blood products represent 90% of placenta accreta spectrum morbidity. Both tranexamic acid and uterine artery embolization independently decrease obstetrical hemorrhage., Objective: This study aimed to provide an evidence-based intraoperative protocol for placenta accreta spectrum management., Study Design: This study was a pre- and postimplementation analysis of concomitant uterine artery embolization and tranexamic acid in cases of patients with antenatally suspected placenta increta and percreta over a 5-year period (2018-2022). For comparison, a 5-year (2013-2017) preimplementation group was used to assess the impact of the uterine artery embolization and tranexamic acid protocol for placenta accreta spectrum. Patient demographics and clinically relevant outcomes were obtained from electronic medical records., Results: A total of 126 cases were managed by the placenta accreta spectrum team, of which 66 had suspected placenta increta/percreta over the 10-year time period. Two patients were excluded from the postimplementation cohort because they did not undergo both interventions. Thus, 30 (30/64; 47%) were treated after implementation of the uterine artery embolization and tranexamic acid protocol for placenta accreta spectrum, and 34 (34/64; 53%) preimplementation patients did not undergo uterine artery embolization or tranexamic acid infusion. With the uterine artery embolization and tranexamic acid protocol, operative times were longer (416 vs 187 minutes; P<.01), and patients were more likely to receive general anesthesia (80% vs 47%; P<.01). However, blood loss was reduced by 33% (2000 vs 3000 cc; P=.03), overall blood transfusion rates decreased by 51% (odds ratio, 0.05 [95% confidence interval, 0.001-0.20]; P<.01), and massive blood transfusion (>10 units transfused) was reduced 5-fold (odds ratio, 0.17 [95% confidence interval, 0.02-0.17]; P=.02). Postoperative complication rates remained unchanged (4 vs 10 events; P=.14). Neonatal outcomes were equivalent., Conclusion: The uterine artery embolization and tranexamic acid protocol for placenta accreta spectrum is an effective approach to the standardization of complex placenta accreta spectrum cases that results in optimal perioperative outcomes and reduced maternal morbidity., (Copyright © 2023 Elsevier Inc.

Background: The second stage of labor requires active patient engagement. Previous studies suggest that coaching can influence the second stage of labor duration. However, a standardized education tool has not been established, and patients face many barriers to accessing childbirth education before delivery., Objective: This study aimed to investigate the effect of an intrapartum video pushing education tool on the second stage of labor duration., Study Design: This was a randomized controlled trial of nulliparous patients with singleton pregnancies ≥37 weeks of gestation admitted for induction of labor or spontaneous labor with neuraxial anesthesia. Patients were consented on admission and block randomized in active labor to 1 of 2 arms in a 1:1 ratio. The study arm viewed a 4-minute video before the second stage of labor on what to anticipate in the second stage of labor and pushing techniques. The control arm received the standard of care: bedside coaching at 10 cm dilation from a nurse or physician. The primary outcome was second stage of labor duration. The secondary outcomes were birth satisfaction (using the Modified Mackey Childbirth Satisfaction Rating Scale), mode of delivery, postpartum hemorrhage, clinical chorioamnionitis, neonatal intensive care unit admission, and umbilical artery gases. Of note, 156 patients were needed to detect a 20% decrease in the second stage of labor duration with 80% power, 2-sided alpha level of .05, and 10% loss after randomization. Funding was provided by the Lucy Anarcha Betsy award from the division of clinical research at Washington University., Results: Of 161 patients, 81 were randomized to standard of care, and 80 were randomized to intrapartum video education. Among these patients, 149 progressed to the second stage of labor and were included in the intention-to-treat analysis: 69 in the video group and 78 in the control group. Maternal demographics and labor characteristics were similar between groups. The second stage of labor duration was statistically similar between the video arm (61 minutes [interquartile range, 20-140]) and the control arm (49 minutes [interquartile range, 27-131]) (P=.77). There was no difference in mode of delivery, postpartum hemorrhage, clinical chorioamnionitis, neonatal intensive care unit admission, or umbilical artery gases between groups. Although the overall birth satisfaction score on the Modified Mackey Childbirth Satisfaction Rating Scale was similar between groups, patients in the video group rated their "level of comfort during birth" and "attitude of the doctors in birth" significantly higher or more positively than patients in the control group (P<.05 for both)., Conclusion: Intrapartum video education was not associated with a shorter second stage of labor duration. However, patients who received video education reported a higher level of comfort and a more favorable perception of their physician, suggesting that video education may be a helpful tool to improve the birth experience., (Copyright © 2023 Elsevier Inc.

The use of tranexamic acid for postpartum hemorrhage has entered obstetrical practice globally with the evidence-based expectation of saving lives. This improvement in the care of women with postpartum hemorrhage has come at a price. For the anesthetist, having tranexamic acid ampoules close at hand would seem an obvious strategy to facilitate its use during cesarean delivery, an important setting for severe hemorrhage. Tragically, we have identified a number of recent instances of inadvertent intrathecal administration of tranexamic acid instead of local anesthetic for spinal anesthesia. Reported cases of this catastrophic error seem to be increasing. The profound neurotoxicity of tranexamic acid causes rapid-onset convulsions, with mortality of 50%. How can these tragic errors be averted? Drug safety alerts have been issued by the US Food and Drug Administration and the World Health Organization, but that is not enough. We recommend extensive dissemination of information to raise awareness of this potential hazard, and local hospital protocols to ensure that tranexamic acid is stored separately from anesthetic drugs, preferably outside the operating room and with an auxiliary warning label. Implementation of safety strategies on a very large scale will be needed to ensure that the life-saving potential of tranexamic acid is not eclipsed by drug-error mortality., (Copyright © 2022 The Author(s).

Background: Although prophylactic tranexamic acid administration after cesarean delivery resulted in a lower incidence of calculated estimated blood loss of >1000 mL or red cell transfusion by day 2, its failure to reduce the incidence of hemorrhage-related secondary clinical outcomes (TRAnexamic Acid for Preventing Postpartum Hemorrhage Following a Cesarean Delivery trial) makes its use questionable. The magnitude of its effect may differ in women at higher risk of blood loss, including those with multiple pregnancies., Objective: This study aimed to compare the effect of tranexamic acid vs placebo to prevent blood loss after cesarean delivery among women with multiple pregnancies., Study Design: This was a secondary analysis of the TRAnexamic Acid for Preventing Postpartum Hemorrhage Following a Cesarean Delivery trial data, a double-blind, randomized controlled trial from March 2018 to January 2020 in 27 French maternity hospitals, that included 319 women with multiple pregnancies. Women with a cesarean delivery before or during labor at ≥34 weeks of gestation were randomized to receive intravenously 1 g of tranexamic acid (n=160) or placebo (n=159), both with prophylactic uterotonics. The primary outcome was a calculated estimated blood loss of >1000 mL or a red blood cell transfusion by 2 days after delivery. The secondary outcomes included clinical and laboratory blood loss measurements., Results: Of the 4551 women randomized in this trial, 319 had a multiple pregnancy and cesarean delivery, and 298 (93.4%) had primary outcome data available. This outcome occurred in 62 of 147 women (42.2%) in the tranexamic acid group and 67 of 152 (44.1%) receiving placebo (adjusted risk ratio, 0.97; 95% confidence interval, 0.68-1.38; P=.86). No significant between-group differences occurred for any hemorrhage-related clinical outcomes: gravimetrically estimated blood loss, provider-assessed clinically significant hemorrhage, additional uterotonics, postpartum blood transfusion, arterial embolization, and emergency surgery (P>.05 for all comparisons)., Conclusion: Among women with a multiple pregnancy and cesarean delivery, prophylactic tranexamic acid did not reduce the incidence of any blood loss-related outcomes., (Copyright © 2022 Elsevier Inc.
