Objective: Puerperal uterine inversion is a rare and severe complication and is associated with short cord, uncontrolled cord traction, placenta accreta, or uterine atony. Case report: A primigravida woman gave birth a 2770 gm newborn at term at our hospital, and clinically presented postpartum hemorrhage, hypovolemic shock, postpartum preeclampsia and urinary retention. She discharged 3 days postpartum, but she complained persist vaginal bleeding and lower abdominal pain for more than 1 month. Uterine inversion was diagnosed and laparoscope surgery for reduction was done. Conclusion: The non-specific clinical presentation made diagnosis of uterine inversion more difficult. Except pelvic examination, sonographic and hysteroscopic images were record in this article. Surgical intervention was performed. A fundus incision was effective for reduction and had low risk of bladder and bowel injury.

Acute Sheehan syndrome appearing within 6 weeks postpartum is a rare form of hypopituitarism caused by postpartum hemorrhage. A 37-year-old Japanese woman experienced a vulvar hematoma after spontaneous labor at 40 weeks gestation, leading to massive postpartum hemorrhage (estimated total blood loss of 3,000 mL). Despite successful cesarean delivery and hematoma drainage, she presented 28 days postpartum with anorexia, fatigue, and hyponatremia after initial recovery. MRI revealed a swollen pituitary gland with subacute hemorrhage, confirming the diagnosis. Hormonal replacement therapy with levothyroxine, hydrocortisone, estrogen, and progesterone was initiated. This is the first reported case of acute Sheehan syndrome following a vulvar hematoma, a condition typically not considered a risk factor for this syndrome. The case highlights the importance of considering rare complications like acute Sheehan syndrome in patients with massive postpartum hemorrhage, even when the pathogenesis is clinically common, such as vulvar hematomas.

Background: Bleeding disorder of unknown cause (BDUC) is a diagnostic category encompassing patients with a clear bleeding phenotype but without identifiable abnormality on hemostatic testing. The optimal management of hemostasis in BDUC patients prior to invasive procedures and childbirth is uncertain. Objectives: Our objective was to characterize periprocedural hemostatic prophylaxis and bleeding outcomes in patients with BDUC. Methods: We conducted a retrospective cohort study of adult patients with BDUC at 2 academic medical centers. Following diagnosis of BDUC, subsequent surgical procedures and childbirths were analyzed using a combination of registry data and manual chart review. Results: We identified 127 patients with mean age of 39.9 years (SD = 16.6); the majority of patients were female (91.3%). Forty-eight major procedures, 70 minor procedures, and 19 childbirths were analyzed. Antifibrinolytic monotherapy was advised for 57% of major procedures, 59% of minor procedures, and 67% of childbirths. Perioperative platelet transfusion was recommended in 26% of major procedures and 9% of minor procedures in combination with other hemostatic agents. Major or clinically relevant nonmajor bleeding occurred in 4.1% (4/98) of procedures with prophylaxis and 10% (2/20) of procedures without prophylaxis. Postpartum hemorrhage occurred in 26% (5/19) of deliveries. Conclusion: In this multiinstitution experience, we found overall low rates of hemostatic complications in procedures completed with hemostatic prophylaxis, although preventing hemorrhage in childbirth and gynecologic procedures remain unmet needs.

Postpartum hemorrhage caused by a pseudoaneurysm of the uterine artery is suspected clinically in the case of abundant metrorrhagia. An ultrasound is performed, followed by further imaging modalities to confirm the diagnosis: CT scan, MRI, and angiography, the latter would also allow embolization. This is admittedly rare, however, since the pseudo aneurysm of the uterine artery is potentially fatal, it must be taken into account in the differential diagnosis of secondary postpartum hemorrhage, allowing adequate and rapid management. We report a case of pseudo aneurysm of the uterine artery, suspected clinically and confirmed by a CT scan, presenting as a secondary postpartum hemorrhage a few hours after delivery by cesarean section. It was eventually managed by embolization with excellent results several days after its onset when the cause was revealed. Angiographic embolization is an effective treatment for postpartum hemorrhage caused by pseudoaneurysm in stable patients. It should be considered before surgery in suitable cases.

We present a rare case of uterine artery pseudoaneurysm (UAP) following an emergency cesarean section, which led to severe vaginal bleeding and subcutaneous hematoma. The patient, a 40-year-old woman with no history of hemophilia or hemostasis disorders, presented with sudden profuse vaginal bleeding and multiple subcutaneous hematomas at the site of the cesarean scar ten days postoperation. Ultrasound and CT scan confirmed the presence of a pseudoaneurysm in the right uterine artery. Due to the unavailability of radiological embolization, surgical ligation of the right internal iliac artery was performed. Postoperative follow-up showed successful resolution of the pseudoaneurysm and cessation of bleeding. This case highlights the importance of considering UAP in the differential diagnosis of postpartum hemorrhage and demonstrates the efficacy of surgical intervention when embolization is not available.

Postpartum hemorrhage (PPH) is an obstetric complication with high associated morbidity. Recombinant activated factor VII (rFVIIa) is used to treat severe PPH when uterotonics fail to stop bleeding. However, data on the safety of rFVIIa treatment of severe PPH from adequately powered trials are lacking. We systematically reviewed published data on the incidence of thromboembolic events (TEs) in women with PPH treated or not treated with rFVIIa (PROSPERO CRD42022360736). Databases (Embase, MEDLINE, BIOSIS, Current Contents, and the Cochrane Library) were searched for peer-reviewed publications published between January 1996 and August 2022 and conference abstracts published between January 2017 and August 2022 using search terms related to thromboembolism or infarction and PPH. Data were extracted from all publications reporting on a general population of women with PPH with information on TEs. Descriptive summary statistics and the estimated proportion of TEs were analyzed using a generalized linear mixed model based on the binomial distribution. Quality assessments were based on the checklist by Downs and Black. From 1637 potentially eligible studies, 55 publications were included reporting on 611 women treated and 32,488 women not treated with rFVIIa. The global estimated proportion of TEs was 1.82% (prediction interval [PI], 0.30-10.23) and 0.72% (PI, 0.03-16.47) in women with severe PPH treated and those not treated with rFVIIa, respectively. The estimated proportions of TEs were similarly small, with wide and largely overlapping PIs. Additional well-designed trials are needed to improve understanding of TE incidence in PPH.

Background: Between 2002 and 2011, the incidence of severe primary postpartum hemorrhage (PPH) in Dutch women with von Willebrand disease (VWD) and hemophilia carriers (HCs) was 8% vs 4.5% in the general population. Objectives: To determine the contemporary incidence of severe primary PPH in women with VWD and HCs. Methods: All women with VWD or HCs who delivered between 2012 and 2017 were selected from all 6 Dutch hemophilia treatment centers. Data on patient and disease characteristics, peripartum hematologic and obstetric management, and outcomes were retrospectively collected. Incidence of severe primary (≥1000 mL of blood loss ≤24 hours after childbirth) and primary (≥500 mL within ≤24 hours after childbirth) PPH was compared with the (1) previous cohort and (2) general Dutch population and between (3) women with VWD and HCs with third-trimester coagulation activity levels

Summary: Background: To assess the equivalence of tranexamic acid (TRAN) versus synthetic oxytocin (OXY) in reducing post-partum blood loss, in full-term patients (37–42 weeks), at low risk of post-partum hemorrhage, with vaginal childbirth. Methods: Phase III, randomized (1:1), open-label, longitudinal, multi-center, prospective clinical trial (Prot. n 63209, ClinicalTrials.gov Identifier: NCT02775773). From January 7, 2020, to June 30, 2023, a total of 256 women were enrolled at two general urban community hospitals in Italy, serving a multi-ethnic patient population with National Health Insurance. The primary outcome was to explore a potential equivalence between the two treatments (OXY and TRAN) in preventing total blood loss. Therefore, we randomized 231 women into two groups: Group A (OXY), 127 women who were administered 10UI intramuscularly within 5 min from childbirth; Group B (TRAN), 104 women to whom 1-g slow intravenous infusion was administered within 5 min from childbirth. Findings: At the time of delivery, mean blood loss for OXY group versus TRAN group was 269.12 mL versus 263.88 mL, respectively, with equivalence between the two groups. Similarly, there was equivalence in total blood loss between the OXY and the TRAN group (397.66 mL versus 405.64 mL, respectively. No statistical differences between Hb levels at admission and discharge in the two groups were reported. No difference was found in terms of additional uterotonic and surgical therapies between the two groups of patients. Neither group showed thrombotic complications at check-up performed after 7 days or after a questionnaire regarding adverse effects, subjected after 40 days. Interpretation: The study shows the equivalence of tranexamic acid versus synthetic oxytocin in post-partum blood loss prophylaxis in term patients at low risk of PPH with vaginal childbirth. The safety profiles of OXY and TRAN were similar. Funding: None.

BACKGROUND: Postpartum hemorrhage is a significant cause of both maternal morbidity and mortality worldwide and is increasing in incidence. This study aimed to assess improvement and identify shortcomings in trainee performance in different simulation systems in the management of postpartum hemorrhage. OBJECTIVE: To perform a pilot study evaluating and comparing high- and low-fidelity simulation models, assessing improvement in repeated performance with high-fidelity mode and identifying mistakes made assessed using Objective Structured Assessment of Technical Skills and thereby exploring what aspects of emergency management of postpartum hemorrhage should be prioritized in teaching settings and assessing what simulation setup is most effective in achieving competence. STUDY DESIGN: This was a prospective randomized, single-blinded, single-institution trial in a population of 17 junior obstetrical trainees at the Charité University Hospital Obstetric Simulation Center in Berlin. Trainees were randomized into 2 groups, with either initial low-fidelity simulation or high-fidelity simulation, followed by repeated assessment of performance, using the high-fidelity model simulation system. Individual simulation sessions were video-recorded and transcribed, and the timing of interventions was documented. Strandardized Objective Structured Assessment of Technical Skills forms were used as a checklist for performance. RESULTS: There was a statistically significant general improvement in performance (P=.02; 24.7–27.2 of 31.0 points; average of 8.7%) in the second cycle of simulation assessment and a statistically significant training effect (P=.043; 24.4–28.4 of 31.0 points; average of 12.9%) in the group that underwent repeat simulation assessment from the initial low-fidelity system to the high-fidelity system compared with the group using the same high-fidelity setup (P=.276; 25.0–25.8 of 31.0; average of 2.4%). CONCLUSION: There was an improvement in the performance when trainees underwent a repeated cycle of simulation assessment changing from a low-fidelity system to a high-fidelity system. Simulation assessment can identify mistakes and learning gaps that are important for obstetrical trainees. This study found that trainees make the same mistakes, regardless of which simulation model was initially used.

Background: Remimazolam has recently been introduced as a maintenance agent for general anesthesia. However, the effect of remimazolam on peripartum prognosis has not been reported. Therefore, this study aimed to compare the effects of remimazolam and propofol for uterotonic drugs following cesarean section. Methods: The electronic medical records of 51 adult women who underwent elective cesarean sections by single obstetrician under general anesthesia were collected. Participants were categorized into two groups: the propofol group and the remimazolam group. General anesthesia was maintained by continuous infusion of propofol or remimazolam after delivery. The number of uterotonic drugs administered during the cesarean section, the estimated blood loss (EBL), and length of hospital stay (LOS) after delivery were assessed. Results: Of the 51 patients included in the study, 35 were in the propofol group and 16 in the remimazolam group. In the remimazolam group, five patients (31.3%, 5/16) received more uterotonics than the standard regimen. Conversely, in the propofol group, 19 patients (54.3%, 19/35) were injected with more uterotonics than the standard regimen. Logistic regression analysis showed that abnormal positioning of the placenta (P = 0.079) and not using remimazolam (P = 0.100) were the most relevant factors associated with the increased use of uterotonics. There was no significant difference in EBL between the two groups. The use of remimazolam was clinically relevant with a shorter LOS (P = 0.059). Conclusions: The use of remimazolam as a maintenance agent did not result in significantly higher use of intrapartum uterotonics compared to the use of propofol. These results cannot exclude all adverse effects of remimazolam during cesarean delivery. Further randomized controlled trials must be conducted to obtain high-quality evidence.

Objectives: To investigate the feasibility, safety, and efficiency after application of a cervical tourniquet during caesarian hysterectomy owing to placenta accreta Study design: It was a monocentric prospective observational study for 3 years. Patients were allocated into two group: Group Tourniquet: (TG) in which a cervical tourniquet was systematically applied during hysterectomy, control group (CG) when the caesarian hysterectomy was performed without. Results: 20 patients in the TG and 23 patients in the CG. Tourniquet application significantly reduced per operative estimated blood loss volume (TG: 530 ± 135 vs 940 ± 120 ml in the CG, p = 0.0074), ΔHB (0.6 [0.3–1.9] vs 2.5[2.5–3.6] g/dl in the CG, p = 0.006) RBC transfusion requirements’ (TG: 2 ± 1.7 vs 4.3 ± 2.1 units in the CG, p = 0.046) procedure duration (TG: 98 ± 21 vs 137 ± 33 min in the CG, p = 0.015), clotting disorders (TG: 1 (5%) vs 6 (26,1%) in the CG, p = 0.013) and the incidence of bladder wounds (TG: 1 (5%) vs 5 (21,7%) in the CG, p = 0.048). There was no significant difference regarding ICU transfer rate (TG: 16 (80%) vs 20 (86.9%) in the CG, p = 0.53) or length of stay (TG: 1.4 [2,3] vs 2.3 [1–4] days in the CG, p = 0.615) and digestive wound (TG: 0 vs 2 (8,7%) in the CG, p = 0.641). Conclusion: In case of a radical management of placenta accreta. A strategy that involves the application of a cervical Tourniquet should be considered as a feasible, safe and above all efficient alternative to prevent blood spoliation.

Background: Postpartum Hemorrhage (PPH) is one of the main causes of maternal mortality, mainly in the poorest regions of the world, drawing attention to the need for strategies for preventing it. This study aims to evaluate the efficacy of prophylactic administration of Tranexamic Acid (TXA) in decreasing blood loss in pregnant women in delivery, preventing PPH. Methods: Systematic review of randomized clinical trials. We searched for publications in PubMed, EMBASE and Cochrane Library databases, with the uniterms “postpartum, puerperal hemorrhage” and “tranexamic acid”, published between January of 2004 and January of 2020. The eligibility criteria were trials published in English with pregnant women assessed during and after vaginal or cesarean delivery about the effect of prophylactic use of TXA on bleeding volume. The random-effects model was applied with the DerSimonian-Laird test and the Mean Difference (MD) was calculated for continuous variables together with each 95% CI. This systematic review was previously registered in the PROSPERO platform under the registration n° CRD42020187393. Results: Of the 630 results, 16 trials were selected, including one with two different doses, performing a total of 6731 patients. The intervention group received a TXA dose that varied between 10 mg.kg−1 and 1g (no weight calculation). The TXA use was considered a protective factor for bleeding (MD: -131.07; 95% CI: -170.00 to -92.78; p = 0.000) and hemoglobin variation (MD: -0.417; 95% CI: -0.633 to -0.202; p = 0.000). In the subgroup analysis related to the cesarean pathway, the effect of TXA was even greater. Conclusion: The prophylactic use of tranexamic acid is effective in reducing the post-partum bleeding volume. PROSPERO registration ID: CRD42020187393.

Objectives: Postpartum hemorrhage (PPH) is a common cause of maternal death worldwide, but data on PPH incidence and influencing factors for nulliparous and multiparous women is scarce. So, the study aimed to assess the differences in PPH incidence and influencing factors between nulliparous and multiparous women. Methods: A multicenter retrospective cohort study was conducted among women who gave birth at ≥ 28 weeks of gestation in Hunan Province, China, from January 2017 to December 2018. Logistic regression assessed PPH-influencing factors, and the receiver operating characteristic curve (ROC curve) assessed the predictive performance of identified factors. Results: A total of 144,845 postpartum women were included in the study. The incidence of PPH (blood loss ≥ 500 ml) was 2.1 % and 1.7 % for nulliparous and multiparous women, respectively. Among the nulliparous and multiparous women, similar influencing factors of PPH included erythrocyte suspension transfusion before childbirth, anemia, soft-birth canal avulsion, Cesarean-section, placenta abruption, and general anesthesia administration before birth. Thrombophlebitis was associated [aOR 18.46(1.67–20.31)] with PPH among only the nulliparous women, while instrument-assisted birth [aOR 1.95(1.16–3.28)] and gestational hypertension [aOR 1.57(1.13–2.19)] were associated with PPH among only the multiparous women. The areas under the ROC-curve for the overall-cohort, nulliparous, and multiparous groups were [0.829(0.821–0.838)], [0.828(0.815–0.840)] and [0.833(0.822–0.844)], respectively. Conclusion: PPH incidence is higher among nulliparous women than among multiparous women, but influencing factors vary relatively by parity. The study findings provide new insights into the use of different approaches to PPH prevention for nulliparous and multiparous women in clinical practice.

Introduction: Postpartum hemorrhage (PPH) is responsible for half of all maternal deaths during childbirth. Despite being preventable and curable, PPH remains the leading cause of maternal death in Ethiopia. Therefore, the aim of this study was to identify the determinants of PPH among women delivered at public hospitals in Addis Ababa, Ethiopia, in 2022. Methods: A facility-based, unmatched case control study with 378 study participants was carried out in selected public hospitals in Addis Ababa, Ethiopia. Women who gave birth and developed PPH were considered cases, while women who gave birth in public hospitals in Addis Ababa and did not develop PPH were controls. Binary and multivariable logistic regression analyses were used to identify independent predictors of PPH. Variables was considered statistically significant in the final model if their p-value was less than 0.05. Results: The result of this study identified that antenatal care follow-up (AOR: 2.58; 95% CI: 1.12, 5.96), history of cesarean delivery (AOR: 3.47; 95% CI: 1.40, 8.58), prolonged labor (AOR: 5.14; CI: 2.07, 12.75), and genital trauma apart from episiotomy (AOR: 4.39; CI: 1.51, 12.81) were determinants of PPH. Conclusion: According to the finding of this study duration of labor, history of cesarean section, antenatal care follow-up, and genital trauma other than episiotomy were independent determinants of PPH. Therefore, it is crucial to screen and closely monitor high-risk mothers during antepartum care visit, including those who have a history of cesarean delivery.

BACKGROUND: Postpartum hemorrhage is a leading cause of maternal morbidity and mortality. Tranexamic acid has proven to be useful in treating hemorrhage from acute blood loss. However, its role in preventing blood loss in women at high risk of postpartum hemorrhage undergoing cesarean delivery is not well studied. OBJECTIVE: This study aimed to assess the role of tranexamic acid in reducing blood loss during elective and unscheduled cesarean deliveries in women at high risk of postpartum hemorrhage. STUDY DESIGN: This was a prospective, placebo-controlled, randomized controlled trial from March 2021 to February 2022 at the Karnatak Lingayat Education Society Dr. Prabhakar Kore Hospital and Medical Research Centre, Belagavi, India. Women at a high risk of postpartum hemorrhage undergoing cesarean delivery were recruited and randomized to receive either tranexamic acid or placebo (1:1) at least 10 minutes before skin incision. High-risk factors for postpartum hemorrhage included obesity, hypertension, multiparity, previous cesarean delivery, multiple pregnancy, abnormally implanted placenta, placenta previa, abruption, uterine leiomyomas, polyhydramnios, and fetal macrosomia. The primary outcome was blood loss, calculated by a formula using pre- and postoperative hematocrit levels. In addition, gravimetrically measured blood loss was measured and compared between the 2 groups. RESULTS: A total of 212 women met the inclusion criteria and were randomized (tranexamic acid [n=106] and placebo [n=106]). The mean blood loss estimates were 400.9 mL in the tranexamic acid group and 597.9 mL in the placebo group (P

Objective: To determine pre-delivery fibrinogen levels in predicting adverse maternal or neonatal outcomes in patients with placental abruption. Materials and method: We conducted a retrospective study of all women admitted for placental abruption between January 2012 and May 2018. Postpartum hemorrhage (PPH), disseminated intravascular coagulation (DIC), massive blood transfusion and hospitalization in intensive care unit parameters were evaluated for maternal outcomes. For the neonatal outcomes, the 5th minute APGAR score, umbilical artery pH and stillbirth were evaluated. Results: The mean predelivery fibrinogen levels were 221.3 ± 111.6 mg/dL. In multivariate logistic regression analysis, fibrinogen level was determined as an independent indicator for PPH, red cell concentrate (RCC) and fresh frozen plasma (FFP) transfusion. When fibrinogen levels decreased below 130 mg/dL, the risk of PPH increased and when fibrinogen levels decreased below 100 mg/dL, the risk of overt DİC and also the risk of red cell concentrate and fresh frozen plasma transfusion increased. In terms of the fetal results, there may be adverse neonatal outcomes when fibrinogen levels are below 250 mg/dL. Conclusion: Predelivery fibrinogen levels are good indicators for predicting adverse maternal outcomes in placental abruption cases. In addition, fibrinogen levels might be a guide for management of placental abruption cases.

Objective: Placenta previa is a health issue during pregnancy when the placenta wholly or partially covers the opening of the uterus. It can result in bleeding during pregnancy or after delivery, and preterm delivery. This study aimed to investigate the risk factors correlated with poorer childbirth outcomes of placenta previa. Materials and methods: Between May 2019 and January 2021, pregnant women diagnosed with placenta previa in our hospital were enrolled. Outcomes were postpartum hemorrhage after childbirth, and lower Apgar score and preterm delivery of the neonate. Laboratory blood examination data preoperatively were collected from medical records. Results: A total of 131 subjects were included, with a median age 31 years. Multivariate analysis showed that fibrinogen reduced risk for postpartum hemorrhage (adjusted odds ratio (aOR): 0.45, 95% confidence interval (CI): 0.26–0.79, p = 0.005). Homocysteine (aOR: 0.73, 95% CI: 0.54–0.99, p = 0.04) reduced the risk while D-dimer (aOR: 1.19, 95% CI: 1.02–1.37, p = 0.02) increased the risk for low Apgar score. Age (aOR: 0.86, 95% CI: 0.77–0.96, p = 0.005) decreased the risk but history of full-term pregnancy more than twice (aOR: 8.58, 95% CI: 2.32–31.71, p = 0.001) increased the risk for preterm delivery. Conclusion: The findings suggest that poorer childbirth outcomes in pregnant women with placenta previa are associated with young age, history of full-term pregnancy, and preoperative concentrations of low fibrinogen, low homocysteine and high D-dimer. This provides obstetricians adjunctive information for early screening of high-risk population and relevant treatment arrangement in advance.

BACKGROUND: Amniotic fluid embolism is an unpredictable and sometimes lethal complication of childbirth. Fibrinogen γ-chain peptide-coated, ADP-encapsulated Liposomes (H12-(ADP)-liposomes), which were developed as a platelet substitute, may be useful to control postpartum hemorrhage with consumptive coagulopathy. OBJECTIVE: This study aimed to establish a hemodynamically stable amniotic fluid embolism animal model and evaluate the efficacy of H12-ADP-liposome infusion in the initial management of postpartum hemorrhage complicated with amniotic fluid embolism–involved coagulopathy. STUDY DESIGN: Pregnant New Zealand white rabbits (28th day of pregnancy or normal gestation period of 29–35 days) underwent cesarean delivery, followed by intravenous administration of amniotic fluid (a total of 3.0 mL administered in 4 doses over 9 minutes). Thereafter, uncontrolled postpartum hemorrhage was induced by transecting the right midartery and concomitant vein in the myometrium. After initial bleeding for 5 minutes, rabbits received isovolemic fluid resuscitation through the femoral vein with an equivalent volume of blood loss every 5 minutes for 60 minutes. The transfusion regimens included platelet-rich plasma, platelet-poor plasma, and a bolus administration of H12-ADP-liposomes followed by platelet-poor plasma transfusion (8 rabbits per group). Moreover, 60 minutes after initiation of bleeding, rabbits received surgical hemostasis by ligation of bleeding vessels, except in cases with spontaneous hemostasis. RESULTS: The administration of amniotic fluid caused thrombocytopenia (56±3 × 103/μL) and prolonged both clotting time (before administration: 130.0±3.0 to 171.0±5.0 seconds) and prothrombin time (4.5±0.1 to 4.7±0.1 seconds). After the initial 5-minute bleeding in the rabbits, the mean arterial pressure fell to 43±2 mm Hg. Platelet-poor plasma transfusion alone further prolonged clotting time and prothrombin time at 60 minutes (192.0±10.0 and 5.2±0.1 seconds, respectively) with decreasing mean arterial pressure to 45 mm Hg throughout the experiment. H12-ADP-liposome infusion and platelet-poor plasma transfusion and platelet-rich plasma transfusion yielded spontaneous hemostasis in 4 of 8 rabbits, whereas platelet-poor plasma transfusion did not stop bleeding in any of the rabbits. The total blood loss was 59±17 mL in the H12-ADP-liposomes and platelet-poor plasma group, which was half of that in the platelet-poor plasma group (124±10 mL). CONCLUSION: H12-ADP-liposome infusion may be effective in the initial management of postpartum hemorrhage complicated with amniotic fluid embolism, resulting in mitigation of consumptive coagulopathy.

The current standard treatment for placenta accreta is a hysterectomy, which carries a significant risk of hemorrhage. Although prophylactic uterine artery embolization (UAE) is established as an effective means of minimizing perioperative bleeding, there are few reports of its use early in pregnancy with invasive placenta.A 45-year-old woman, gravida 6, para 1, at 11 weeks of gestation presented with heavy, painless uterine bleeding and was diagnosed with a spontaneous abortion complicated by cervical pregnancy and placenta accreta. The patient underwent bilateral UAE followed by gravid hysterectomy.This case report encourages prophylactic UAE prior to abdominal hysterectomy in patients with early gestational cervical pregnancy and placenta accreta to minimize blood loss during surgery.

BACKGROUND: Rates of maternal morbidity and mortality experienced by women in the United States have been shown to vary significantly by race, most commonly attributed to differences in access to healthcare and socioeconomic status. Recent data showed that Asian Pacific Islanders have the highest rate of maternal morbidity despite having a higher socioeconomic status. In the military, women of all races are granted equal access to healthcare, irrespective of socioeconomic class. We hypothesized that within the military, there would be no racial disparities in maternal outcomes because of universal healthcare. OBJECTIVE: This study aimed to evaluate if universal access to healthcare, as seen in the military healthcare system, leads to similar rates of maternal morbidity regardless of racial or ethnic background. STUDY DESIGN: This was a retrospective cohort study of data from the National Perinatal Information Center reports obtained from participating military treatment facilities from April 2019 to March 2020 and included 34,025 deliveries. We compared racial differences in the incidence of each of the following 3 outcomes: postpartum hemorrhage, severe maternal morbidity among women with postpartum hemorrhage including transfusion, and severe maternal morbidity among women with postpartum hemorrhage excluding transfusion. RESULTS: A total of 41 military treatment facilities (a list of participating military treatment facilities are provided in the Appendix) provided data that were included. There was an increased rate of postpartum hemorrhage (relative risk, 1.73; 95% confidence interval, 1.45–2.07), severe maternal morbidity including transfusion (relative risk, 1.22; 95% confidence interval, 0.93–1.61), and severe maternal morbidity excluding transfusion (relative risk, 1.97; 95% confidence interval, 1.02–3.8) among Asian Pacific Islander women when compared with Black or White women. CONCLUSION: Even with equal access to healthcare in the military, Asian Pacific Islander women experience statistically significant increased rates of postpartum hemorrhage and severe maternal morbidity excluding transfusion when compared with Black or White women. The increased rates of severe maternal morbidity including transfusion were not statistically significant.

BACKGROUND: Newer research comparing routes of medication administration has extended beyond efficacy as a primary endpoint to incorporate patient preference. However, little is known about the preferences of pregnant women in terms of routes of medication administration, specifically with regards to hemorrhage prevention and control. OBJECTIVE: This study aimed to understand the preferences of pregnant women in terms of medical interventions to prevent hemorrhage at the time of delivery. STUDY DESIGN: Surveys were distributed from April 2022 to September 2022 using electronic tablets at a single urban center with an annual delivery volume of 3000 women per year to women >18 years of age who were either currently pregnant or have been pregnant in the past. Subjects were asked to choose their preferred route of administration from the following options: intravenous, intramuscular, or subcutaneous. The primary outcome was patient preference on the route of medication administration during a hemorrhage event. RESULTS: The study cohort included 300 patients, mostly African American (39.8%) followed by White (32.1%), and the majority of the participants ranged from 30 to 34 years of age (31.7%). When asked which method of administration they would prefer to prevent hemorrhage before birth, the results were as follows: 31.1% would prefer intravenous, 23.0% had no preference, 21.2% were unsure, 15.9% preferred subcutaneous, and 8.8% preferred intramuscular administration. In addition, 69.4% of respondents reported that they have never declined or avoided intramuscular administration of medication if recommended by their physician. CONCLUSION: Although some survey participants preferred an intravenous route of administration, 68.9% of subjects were unsure, had no preference, or preferred nonintravenous routes. This information is helpful particularly in low-resource settings where intravenous treatments are not readily available or in urgent clinical situations in which intravenous administration routes are not easily obtainable in high-risk patients.

BACKGROUND: Early detection of postpartum hemorrhage risk factors by healthcare providers during pregnancy and the postpartum period may allow healthcare providers to act to prevent it. Developing a prediction model that incorporates several risk factors and accurately calculates the overall risk for postpartum hemorrhage is necessary. OBJECTIVE: This study used a traditional analytical approach and a machine learning model to predict postpartum hemorrhage. STUDY DESIGN: Women who gave birth at the Khaleej-e-Fars Hospital in Bandar Abbas, Iran, were evaluated retrospectively between January 1, 2020, and January 1, 2022. These pregnant women were divided into 2 groups, namely those who had postpartum hemorrhage and those who did not. We used 2 approaches for the analysis. At the first level, we used the traditional analysis methods. Demographic factors, maternal comorbidities, and obstetrical factors were compared between the 2 groups. A bivariate logistic regression analysis of the risk factors for postpartum hemorrhage was done to estimate the crude odds ratios and their 95% confidence intervals. In the second level, we used machine learning approaches to predict postpartum hemorrhage. RESULTS: Of the 8888 deliveries, we identified 163 women with recorded postpartum hemorrhage, giving a frequency of 1.8%. According to a traditional analysis, factors associated with an increased risk for postpartum hemorrhage in a bivariate logistic regression analysis were living in a rural area (odds ratio, 1.41; 95% confidence interval, 1.08–1.98); primiparity (odds ratio, 3.16; 95% confidence interval, 1.90–4.75); mild to moderate anemia (odds ratio, 5.94; 95% confidence interval 2.81–8.34); severe anemia (odds ratio, 6.01; 95% confidence interval 3.89–11.09); abnormal placentation (odds ratio, 7.66; 95% confidence interval, 2.81–17.34); fetal macrosomia (odds ratio, 8.14; 95% confidence interval, 1.02–14.47); shoulder dystocia (odds ratio, 7.88; 95% confidence interval, 1.07–13.99); vacuum delivery (odds ratio, 2.01; 95% confidence interval, 1.15–5.98); cesarean delivery (odds ratio, 1.86; 95% confidence interval, 1.12–3.79); and general anesthesia during cesarean delivery (odds ratio, 7.66; 95 % confidence interval, 3.11–9.36). According to machine learning analysis, the top 5 algorithms were XGBoost regression (area under the receiver operating characteristic curve of 99%), XGBoost classification (area under the receiver operating characteristic curve of 98%), LightGBM (area under the receiver operating characteristic curve of 94%), random forest regression (area under the receiver operating characteristic curve of 86%), and linear regression (area under the receiver operating characteristic curve of 78%). However, after considering all performance parameters, the XGBoost classification was found to be the best model to predict postpartum hemorrhage. The importance of the variables in the linear regression model, similar to traditional analysis methods, revealed that macrosomia, general anesthesia, anemia, shoulder dystocia, and abnormal placentation were considered to be weighted factors, whereas XGBoost classification considered living residency, parity, cesarean delivery, education, and induced labor to be weighted factors. CONCLUSION: Risk factors for postpartum hemorrhage can be identified using traditional statistical analysis and a machine learning model. Machine learning models were a credible approach for improving postpartum hemorrhage prediction with high accuracy. More research should be conducted to analyze appropriate variables and prepare big data to determine the best model.

Background and objective: During the past few years, an increased number of postpartum hemorrhages have been noticed, even in high-income countries. It has been suggested that this escalation could be associated with increased obstetric interventions. Among such interventions, anesthesia is one of the most prevalent. The present study aimed to investigate the influence of peripartum anesthesia on total blood loss during the 24 hours after delivery. Methods: We performed a complementary analysis from a prospective cohort study that evaluated postpartum bleeding within 24 hours after birth. The study was performed between February 1st, 2015 and March 31st, 2016 at the Women’s Hospital at the Universidade Estadual de Campinas, Brazil. Postpartum bleeding was measured using a calibrated drape and summing the blood contained in the compresses and pads used for 24 hours. We calculated means, percentages, and standard deviation and performed Mann-Whitney analysis for the relation of anesthesia with Postpartum Hemorrhage (PPH) and logistic regression for drugs used in the anesthesia with PPH, using SAS 9.4 software. Results: We included 270 women in the study; of these, 168 received anesthesia for delivery and almost 50% of them had spinal and epidural anesthesia. The mean blood loss within 24 hours after delivery did not show differences between those who did and those who did not receive obstetrical anesthesia (579.0 ± 361.6 vs. 556.6 ± 360.6; p = 0.57). Logistic regression showed that anesthesia, the type of anesthesia, and the drug used did not influence the PPH above 500 mL and above 1000 mL within 2 hours (p > 0.05). Conclusion: Anesthesia did not influence postpartum bleeding after vaginal delivery.

Background: The rotational thromboelastogram (ROTEM) has been used in the management of massive bleeding and transfusion strategy. This study investigated ROTEM parameters measured during Cesarean section as predictors for the progression of persistent postpartum hemorrhage (PPH) in parturients with placenta previa. Methods: This prospective observational study recruited 100 women scheduled for elective Cesarean section after being diagnosed with placenta previa. Recruited women were divided into two groups according to the amount of estimated blood loss: the PPH group (PPH > 1500 ml) vs. the non-PPH group. ROTEM with laboratory tests was performed three times, preoperative, intraoperative, and postoperative time, which were compared between the two groups. Results: The PPH and non-PPH groups included 57 and 41 women, respectively. The area under the receiver-operating characteristic curve of postoperative FIBTEM A5 to detect PPH was 0.76 (95% CI = 0.64 to 0.87; P

Background: Postpartum hemorrhage is the major cause of maternal deaths due to childbirth and also responsible for maternal morbidity. Objectives: In this study we set out to look the incidence of postpartum hemorrhage in our population, to identify the most important risk factors for postpartum hemorrhage and thus develop a predictive risk calculator for postpartum hemorrhage and transfusion. Study design: data was taken from patients who presented vaginal delivery or cesarean section from January 1 to December 31, 2016, the variables taken into account as risk factors were as follows: Gestational age, history of chronic or gestational hypertension, preeclampsia, previous abortions, parity, previous cesarean section, placenta previa, labor time, and postpartum hemorrhage as the event of interest. An objective quantification was performed on a weight scale in grams for the estimation of bleeding, considering postpartum hemorrhage those with >500 ml in vaginal delivery and >1000 ml of blood loss in cesarean section. Subsequently, a predictive risk calculator was developed using the Naïve Bayes algorithm. Results: A success rate of 58% was obtained in the identification of patients at high risk of hemorrhage, and 36% for transfusion, with a sensitivity of 50.7% and specificity of 64.06%, identifying as risk factors for postpartum hemorrhage gestational age between 35 and 40 weeks, hypertension and preeclampsia, previous cesarean section, duration of labor

BACKGROUND: There is debate on whether uterine gauze packing or intrauterine balloon tamponade is safer and more effective as a surgical management option for treating postpartum hemorrhage. OBJECTIVE: This study aimed to compare intra- and postoperative outcomes of intrauterine balloon tamponade and uterine gauze packing in patients with postpartum hemorrhage. STUDY DESIGN: A range of databases such as Cochrane and PubMed were searched using terms including “post-partum haemorrhage,” “uterine balloon tamponade,” and “uterine gauze packing.” All observational studies comparing intrauterine balloon tamponade with uterine gauze packing were included. Five studies were identified enrolling 821 adult patients diagnosed with postpartum hemorrhage. Primary outcomes included blood loss volume, success rates, and maternal mortality. Secondary outcomes comprised requiring additional interventions, postoperative hemoglobin levels, and requiring blood transfusions. Fixed and random models were used for analysis. RESULTS: Intrauterine balloon tamponade seemed to be a superior option to uterine gauze packing. Intrauterine balloon tamponade was better in reducing intraoperative blood loss, with a statistically significant improvement (P

Background: Tranexamic acid is one component of a complex management algorithm for postpartum hemorrhage. In Japan, the 2010 obstetric hemorrhage management guidelines was revised in 2017, adding the recommendation for the administration of tranexamic acid for postpartum hemorrhage. This research aims to delineate the temporal trends in tranexamic acid administration in patients undergoing cesarean deliveries and to examine the impact of the obstetric hemorrhage management guidelines implementation., Methods: An interrupted time series analysis was conducted on data from patients who underwent cesarean deliveries from April 2012 to August 2021, sourced from Japan's nationwide health insurance claims database. We examined the trends of tranexamic acid usage and blood transfusion use before and after the implementation of the revised guidelines in 2017., Results: The study cohort comprised 91 166 cesarean deliveries. Prior to the guideline implementation, the rate of tranexamic acid usage decreased. Post-guidelines implementation, there was a statistically significant increase in the rate of tranexamic acid use, with a quarterly percentage change of 0.48% (95% confidence interval: 0.36 to 0.60; P < 0.001). The guidelines implementation in 2017 was not significantly associated with a change in the rate of transfusions., Conclusions: This interrupted time series analysis demonstrated a significant increase in the rate of tranexamic acid administration following the implementation of the revised guidelines, reversing the previously observed downward trend. Our findings could reflect the impact of the revised guideline on the use of tranexamic acid for postpartum hemorrhage, but this did not translate to fewer blood transfusions., (Copyright © 2024 Elsevier Ltd.

Background: Advances in medicine have enabled more patients with congenital heart disease (CHD) to become pregnant. However, these patients face significant challenges during the peripartum period. Current peripartum anesthesia guidelines for CHD patients mainly rely on case reports and small series., Methods: In this retrospective study at a high-volume tertiary care center, we analyzed peripartum anesthetic approaches, postpartum hemorrhage (PPH) incidence, and maternal outcomes in CHD patients stratified by the modified World Health Organization (mWHO) classification., Results: Among 85 473 deliveries between 2009 and 2023, 409 occurred in 282 patients with CHD. Cesarean deliveries were significantly more frequent in mWHO class III, p=0.005. Labor epidural analgesia was the most common analgesic modality for vaginal deliveries (epidural rate was 71.1% with no differences between mWHO classes). Anesthesia management for cesarean deliveries varied significantly by class p<0.001. While spinal anesthesia was predominant in classes I and II, combined spinal-epidural anesthesia was more common in class III. PPH incidence was 6.4%, with no significant difference across classes, and no association was found between mWHO class severity and PPH risk (OR 0.97; 95% CI; 0.93 to 1.02, p=0.2). Higher mWHO classes correlated with significantly higher intensive care unit (ICU) admission rates, longer hospital stays, and one-year cardiac hospitalizations., Conclusion: In this retrospective study on the peripartum anesthetic management and outcomes of CHD patients stratified by mWHO class, cases with greater mWHO class were more likely to deliver preterm, by cesarean delivery, with a combined spinal-epidural anesthetic and an arterial line placement for that cesarean delivery. They overall had a longer hospital stay and were more likely to be admitted to the ICU. However, the overall risk of PPH did not increase with mWHO class severity., (Copyright © 2024 Elsevier Ltd.

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.

Background: Females with von Willebrand disease (VWD) do not show the same increases in von Willebrand factor and factor (F)VIII levels during pregnancy as females without VWD and are at higher risk of excessive bleeding associated with childbirth. Data on hemostatic management for childbirth in VWD patients are limited., Objectives: To evaluate the dosing, efficacy, and safety of plasma-derived von Willebrand factor/FVIII (wilate) for prevention of excessive bleeding associated with childbirth in females with any type of VWD., Methods: Data for females with VWD who received wilate for hemostatic coverage for childbirth during 2 prospective clinical studies were analyzed., Results: Ten females with VWD and a mean age at enrolment of 29.6 years were treated with wilate to prevent excessive bleeding associated with childbirth. Two patients had type 1, 4 had type 2 (2 2A, 1 2B, and 1 2M), and 4 had type 3 VWD. Of the 10 deliveries, 5 were by cesarean section. Patients received a mean of 9.5 infusions of wilate over 6.8 exposure days, with a mean total dose of 234 IU/kg per delivery and 25 IU/kg per infusion. Hemostatic management for all deliveries was rated excellent or good, with no excessive bleeding during delivery and no postpartum bleeding during the period of wilate treatment in any patient. Two patients experienced 8 possible or probable treatment-related adverse events; all were mild or moderate and resolved. No thromboembolic events were observed., Conclusion: The results of this case series indicate that wilate provided effective hemostatic cover for childbirth in females with VWD during delivery and postpartum., Competing Interests: Declaration of competing interests A.I.’s institution has received grant/research support from Bayer, Novo Nordisk, Pfizer, Roche, Sanofi, and Takeda.

Background: Bleeding disorder of unknown cause (BDUC) is a diagnostic category encompassing patients with a clear bleeding phenotype but without identifiable abnormality on hemostatic testing. The optimal management of hemostasis in BDUC patients prior to invasive procedures and childbirth is uncertain., Objectives: Our objective was to characterize periprocedural hemostatic prophylaxis and bleeding outcomes in patients with BDUC., Methods: We conducted a retrospective cohort study of adult patients with BDUC at 2 academic medical centers. Following diagnosis of BDUC, subsequent surgical procedures and childbirths were analyzed using a combination of registry data and manual chart review., Results: We identified 127 patients with mean age of 39.9 years (SD = 16.6); the majority of patients were female (91.3%). Forty-eight major procedures, 70 minor procedures, and 19 childbirths were analyzed. Antifibrinolytic monotherapy was advised for 57% of major procedures, 59% of minor procedures, and 67% of childbirths. Perioperative platelet transfusion was recommended in 26% of major procedures and 9% of minor procedures in combination with other hemostatic agents. Major or clinically relevant nonmajor bleeding occurred in 4.1% (4/98) of procedures with prophylaxis and 10% (2/20) of procedures without prophylaxis. Postpartum hemorrhage occurred in 26% (5/19) of deliveries., Conclusion: In this multiinstitution experience, we found overall low rates of hemostatic complications in procedures completed with hemostatic prophylaxis, although preventing hemorrhage in childbirth and gynecologic procedures remain unmet needs., (© 2024 The Authors.)

Objective: Puerperal uterine inversion is a rare and severe complication and is associated with short cord, uncontrolled cord traction, placenta accreta, or uterine atony., Case Report: A primigravida woman gave birth a 2770 gm newborn at term at our hospital, and clinically presented postpartum hemorrhage, hypovolemic shock, postpartum preeclampsia and urinary retention. She discharged 3 days postpartum, but she complained persist vaginal bleeding and lower abdominal pain for more than 1 month. Uterine inversion was diagnosed and laparoscope surgery for reduction was done., Conclusion: The non-specific clinical presentation made diagnosis of uterine inversion more difficult. Except pelvic examination, sonographic and hysteroscopic images were record in this article. Surgical intervention was performed. A fundus incision was effective for reduction and had low risk of bladder and bowel injury., (Copyright © 2024. Published by Elsevier B.V.)

Objective: PPH is usually unpredictable; and such fast, urgent and sudden massive life-threating hemorrhage. This study is to assess the efficacy of transarterial embolization (TAE) in treating severe PPH in a single institution over a period of 20 years. Materials and methods: From January 2000 to October 2019, all women with acute PPH more than 1500 cc and/or DIC were enrolled in this retrospective study. These women were divided into two groups according to whether they have received TAE as the second-line treatment. Group 1 (n = 27) included women without receiving TAE from January 1, 2000 to October 31, 2009, and group 2 (n = 30) included those who receiving TAE from November 1, 2009 to October 31, 2019. Results: The overall success rate of TAE in control the PPH and preserved the uterus is 80%. The hemoglobin 12 h after PPH in group 2 is significantly lower than in group 1 (7.64 ± 1.6 vs. 8.58 ± 1.9, respectively. P = 0.05). Total unit of packed red blood cell (pRBC) transfusion is significantly higher in the group 2 than group 1 (9.8 ± 5.7 vs. 6.8 ± 3.9; p = 0.03). The rate of hysterectomy is significantly higher in group 1 than group 2 (46.7 vs. 20%; p

Precipitous delivery is associated with rapid cervical dilation and fetal descent. Complications of precipitous delivery can include vascular trauma, uterine rupture, and uterine artery laceration. Uterine artery laceration is a rare complication that can lead to significant postpartum hemorrhage and injury. Careful evaluation for trauma and aggressive resuscitation are critical to prevent maternal morbidity and mortality. This is a case report of a 39-year-old woman, gravida 2 para 1, at 39 weeks of gestation who delivered after induction of labor due to chronic hypertension. Her labor course was precipitous and complicated by uterine rupture and uterine artery laceration with postpartum hemorrhage that required massive transfusion, exploratory laparotomy with a supracervical hysterectomy, and interventional radiology for uterine and cervical artery embolization. This seems to be the first published case report of precipitous delivery associated with uterine artery laceration and uterine rupture. Thorough evaluation after precipitous delivery is critical to decrease maternal morbidity and mortality secondary to uterine artery injury.

Purpose: To evaluate the effectiveness of adding carbetocin to regular uterotonic agents for prevention of postpartum hemorrhage (PPH) after cesarean section for twin pregnancies. Methods: This is a retrospective uncontrolled before-after study done in a tertiary center in Taiwan, 2010–2017. Women with twin pregnancies that underwent cesarean section were enrolled. The control group (n = 114) received oxytocin infusion and direct uterine injection. In addition to these, the study group (n = 127) received 100ug of intravenous carbetocin. Primary endpoint was the change in hemoglobin. Secondary endpoints included risk of PPH and undiagnosed PPH (Hb dropped more than 2 g/dL), blood loss, the need for additional uterotonic maneuvers, and blood transfusion. Hemodynamic changes were also investigated. Results: After adjusting for confounding factors, the change in Hb (0.35 g/dL, 95% CI: −0.03∼0.74) and incidence of PPH (OR 0.30, 95% CI: 0.03∼3.28) were comparable in both groups. However, women with undiagnosed PPH decreased (OR 0.43, 95% CI:0.22∼0.85). Total blood loss in 24 h after delivery also decreased (−40.33 mL, 95%CI: −80.32∼ −0.34). The use of extra uterotonic medications and the need for blood transfusion did not differ. The systolic blood pressure 4 h after childbirth was higher in the carbetocin group (6.71, 95% CI: 2.27∼11.15). Conclusion: The use of carbetocin in addition to regular uterotonic agents decreased total blood loss and undiagnosed PPH. Also, systolic blood pressure 4 h after childbirth is higher in the carbetocin group. There was no significant difference in hemoglobin change and risk of PPH.

Objective: Incarcerated gravid uterus is a condition in which uterine myoma and intraperitoneal adhesion lead to persistent uterine retroversion. Accurate diagnosis before cesarean section is crucial so that the procedure can be planned with regard to the spatial relationship between the uterine incision and other organs. This study investigated the effects of well-planned management on the outcome of cesarean sections. Materials and methods: Four patients with incarcerated gravid uterus who received well-planned management and preoperative magnetic resonance imaging were compared with three unexpected patients who were operated without preoperative diagnosis. Results: In the preoperatively diagnosed group, compared with the non-preoperatively diagnosed group, the frequency of cervical canal damage tended to be lower (0% vs. 100%), blood loss tended to be less (1171 ± 290 mL vs. 2000 ± 300 mL), and surgery duration tended to be shorter (82 ± 17 min vs. 147 ± 84 min). None of the preoperatively diagnosed cases required allogeneic blood transfusion, and no organ damage was observed. Conclusion: The early detection of a suspected incarcerated uterus, and a thorough understanding of diagnostic methods and the use of preoperative magnetic resonance imaging and ultrasonography facilitate the safe performance of a cesarean section.

Objective: To analyze the correlation between placenta related disease of pregnant women with antecedent hysteroscopic adhesiolysis due to intrauterine adhesions (IUA). Materials and methods: This is a single center, non-randomized, open-label, retrospective cohort Study. 74 patients who had adhesiolysis and hormone therapy for IUA and progressed into the third trimester were group A and 296 without IUA were group B. The main outcome measure is the incidence of placenta related disease including placenta accreta spectrum, placenta previa, placental abruption, intrauterine growth restriction (IUGR), and pregnancy-induced hypertension (PIH). The second outcome is the perinatal, and intrapartum complications. Results: Patients in group A had a higher frequency of prior pregnancy times (2.51 ± 1.56 vs.1.84 ± 1.06, p = 0.001) and lower frequency of prior delivery times (0.20 ± 0.41 vs. 1.30 ± 0.51, p

Abstract Background Maternal mortality in sub‐Saharan Africa is approximately 500 to 1000 per 100 000 births (vs. approximately 5‐20 in developed countries). Postpartum hemorrhage (PPH) is deemed responsible for 30% to 50% of the deaths. Objective To study PPH, risk factors, and mortality in metropolitan Mozambique to inform future studies and intervention strategies. Materials/Methods Retrospective cross‐sectional data extraction from all charts available to us (n = 495) recording deliveries between January and June 2018 at Maputo Central Hospital. Data included age, maternal survival, HIV status, parity, delivery mode, complications, vital signs, laboratory values, and maternal/fetal data. PPH was determined by charted diagnosis, interventions for hemorrhaging, placental abruption, transfusion, or blood loss. Autopsy reports from all deceased patients (n = 35) were examined. Results Median age was 29 years with 17% HIV prevalence. Risk factors for PPH (frequency, 12%) included parity (adjusted odds ratios (AORs) for 3+ versus nulliparity, 7.20 (95% confidence interval [CI], 2.46‐21.10), gestation length (AOR, 0.86; CI, 0.81‐0.92 per week), and body temperature (AOR, 1.10; CI, 1.04‐1.16 per 0.1°C). Maternal mortality was strongly associated with PPH (AOR, 5.22; 95% CI, 2.26‐12.08) and HIV (AOR, 11.66; 95% CI, 4.72‐28.78). Laboratory values (n = 241) were available from mothers experiencing complications (approximately 50%). Anemia (prevalence 54%) was a strong predictor of PPH with an inverse relationship between hemoglobin levels on admission (AOR, 0.62; 95% CI, 0.50‐0.77 per g/dL higher hemoglobin) and the probability of later suffering from PPH. Mothers who died following PPH had lower median hemoglobin (6.2 g/dL) than mothers who survived (9.2 g/dL). Protocols to estimate peripartum blood loss were not used; antifibrinolytics and/or cryoprecipitate were unavailable. Conclusion Postpartum hemorrhage is a serious problem even in metropolitan areas of sub‐Saharan Africa, and anemia influenced bleeding and death substantially. To address this problem, it is critical to raise awareness and region‐specific prevention and intervention protocols.

Obstetric tetanus is defined as a C. tetani infection that occurs during pregnancy or within six weeks of delivery. In Peru, there are no reports of obstetric tetanus cases. Here we report a sixth case of obstetric tetanus in a puerperal woman who underwent curettage for postpartum hemorrhage, despite immunization against tetanus.

Acute obstetric coagulopathy secondary to postpartum hemorrhage (PPH) is associated with poor outcome. There is evidence that Tranexamic Acid (TA), an antifibrinolytic drug, is an efficient tool of patient blood management in association with uterotonics to reduce mortality due to postpartum hemorrhage (PPH). Recent trials investigated its preventive administration before PPH. This review summarizes their major results and introduces the ongoing debate on a systematic prophylaxis of coagulopathy before PPH occurs.

Postpartum hemorrhage (PPH) is an obstetric complication with high associated morbidity. Recombinant activated factor VII (rFVIIa) is used to treat severe PPH when uterotonics fail to stop bleeding. However, data on the safety of rFVIIa treatment of severe PPH from adequately powered trials are lacking. We systematically reviewed published data on the incidence of thromboembolic events (TEs) in women with PPH treated or not treated with rFVIIa (PROSPERO CRD42022360736). Databases (Embase, MEDLINE, BIOSIS, Current Contents, and the Cochrane Library) were searched for peer-reviewed publications published between January 1996 and August 2022 and conference abstracts published between January 2017 and August 2022 using search terms related to thromboembolism or infarction and PPH. Data were extracted from all publications reporting on a general population of women with PPH with information on TEs. Descriptive summary statistics and the estimated proportion of TEs were analyzed using a generalized linear mixed model based on the binomial distribution. Quality assessments were based on the checklist by Downs and Black. From 1637 potentially eligible studies, 55 publications were included reporting on 611 women treated and 32,488 women not treated with rFVIIa. The global estimated proportion of TEs was 1.82% (prediction interval [PI], 0.30-10.23) and 0.72% (PI, 0.03-16.47) in women with severe PPH treated and those not treated with rFVIIa, respectively. The estimated proportions of TEs were similarly small, with wide and largely overlapping PIs. Additional well-designed trials are needed to improve understanding of TE incidence in PPH., (© 2024 The Authors.)

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).

Background: Between 2002 and 2011, the incidence of severe primary postpartum hemorrhage (PPH) in Dutch women with von Willebrand disease (VWD) and hemophilia carriers (HCs) was 8% vs 4.5% in the general population., Objectives: To determine the contemporary incidence of severe primary PPH in women with VWD and HCs., Methods: All women with VWD or HCs who delivered between 2012 and 2017 were selected from all 6 Dutch hemophilia treatment centers. Data on patient and disease characteristics, peripartum hematologic and obstetric management, and outcomes were retrospectively collected. Incidence of severe primary (≥1000 mL of blood loss ≤24 hours after childbirth) and primary (≥500 mL within ≤24 hours after childbirth) PPH was compared with the (1) previous cohort and (2) general Dutch population and between (3) women with VWD and HCs with third-trimester coagulation activity levels <50 international units (IU)/dL vs ≥50 IU/dL and (4) women treated with vs without peripartum hemostatic prophylaxis., Results: Three-hundred forty-eight deliveries (151 VWD, 167 hemophilia A, and 30 hemophilia B carriers) were included. The severe primary PPH incidence was 10% (36/348) and remained stable over time, whereas this incidence has increased in the general population (to 8%), leading to a similar risk ( P  = .17). Severe primary PPH risk was comparable between women with coagulation activity levels <50 and ≥50 IU/dL (11% [7/66] vs 10% [29/279]; odds ratio, 1.02; 95% CI, 0.43-2.44) and comparable between those with and those without prophylaxis (12% [11/91] vs 10% [25/254]; odds ratio, 1.26; 95% CI, 0.59-2.68)., Conclusion: Severe primary PPH in women with VWD and HCs remained stable and is comparable with the increasing prevalence in the general population. More research is needed to find the optimal pregnancy management strategy for safe delivery in VWD and HC., (© 2024 The Author(s).)

Objectives: To compare whether the clinical features of preeclampsia (PE) or gestational hypertension (GH) were different in pregnancies after a frozen embryo transfer (FET), depending on the FET regimen used., Study Design: A retrospective study including 58 pregnancies with PE and 64 pregnancies with GH, all with singleton live births. Pregnancies were stratified according to the presence or absence of a corpus luteum (CL)., Main Outcome Measures: Clinical characteristics of PE and GH, maternal background factors, postpartum hemorrhage (PPH), key perinatal outcomes., Results: Among PE patients, no difference was found in the clinical characteristics and in the maternal background factors, when comparing women with a CL to women without a CL. PE patients in the group without a CL had a hemorrhage of > 500 mL or > 1000 mL significantly more often than patients with a CL. Multivariable analyses confirmed this risk. Perinatal outcomes were similar. Among GH patients, there was no difference in the clinical features and maternal background factors, when comparing CL cycles to cycles without a CL. The amount of PPH was higher among the patients without a CL, but the frequency of a > 500 mL or > 1000 mL hemorrhage was similar between groups. No risk increase was seen in multivariable analyses., Conclusions: Among FET patients with PE, the risk of PPH wasincreased in pregnancies after cycles without a CL, compared to cycles with a CL. The presence or absence of a CL did noteffectthe severity of PE and GH, the duration of pregnancy or blood pressure levels., 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 The Authors.
