Abstract Background The prostaglandin E1 analog “misoprostol” is a drug that has powerful ecbolic effects and can be beneficial in the prevention and treatment of postpartum hemorrhage, which is the leading cause of maternal mortality worldwide. Objectives To assess the value of adding intrauterine misoprostol together with intravenous oxytocin injection compared with sublingual misoprostol together with intravenous oxytocin injection during elective cesarean section to reduce blood loss intraoperatively and prevent postpartum hemorrhage. Methods A total of 192 pregnant women were counseled and recruited from the labor and delivery unit at Kasr Al Aini Hospital, Cairo University, and equally randomized into two groups. Group (A) included 96 women who received intrauterine misoprostol (400 mg) + oxytocin. Group (B) included 96 women who received sublingual misoprostol (400 mg) + oxytocin. The primary outcome of our study was estimation of the amount of blood loss during and after cesarean delivery. The secondary outcomes were the incidence of PPH within the first 6 h after labor, the need for blood transfusion, the need for any supplementary ecbolic drugs, the need for additional surgical intervention for PPH, changes in hematocrit and hemoglobin in both groups after delivery, and the incidence of side effects of the study medications. Results We observed a significant discrepancy between the two groups in terms of postoperative Hb and Hct, postoperative differences (pre- and post-Hb and post-Hct) and EBL favoring the intrauterine group. However, no significant difference was observed between the groups with respect to excessive blood loss > 1000 ml in the 1st six hours, the need for supplementary ecbolics, the necessity for blood or blood prod, the need for additional surgical intervention (for PPH) or side effects. Conclusion Intrauterine misoprostol combined with oxytocin intravenous infusion is more effective than sublingual misoprostol combined with oxytocin intravenous infusion in lowering intraoperative blood loss and preventing postpartum hemorrhage in elective cesarean section. Trial registration This trial was retrospectively registered with the ClinicalTrials.gov Registry on 12-April-2024 (registration number: NCT06364098).

Abstract Background Intractable postpartum hemorrhage (PPH) during cesarean section has been a significant concern for obstetricians. We aimed to explore the effectiveness and safety of a new type of uterine compression suture, the step-wise surgical technique of knapsack-like sutures for treating intractable PPH caused by uterine atony and placenta factors in cesarean section. Methods The step-wise surgical technique of knapsack-like sutures was established on the basis of the artful combination of vertical strap-like sutures and an annular suture-ligation technique. This novel surgical technique was applied to 34 patients diagnosed with PPH during cesarean section due to severe uterine atony and placental factors in our department. The hemostatic effects, clinical outcomes and follow-up visit results were all reviewed and analyzed. Results This new uterine compression suture successfully stopped bleeding in 33 patients, and the effective rate was 97.06%. Only 1 patient failed and was changed to use bilateral uterine arterial embolization and internal iliac artery embolization. The follow-up visits indicated that 33 patients restored menstruation except for 1 who was diagnosed with amenorrhea. The gynecological ultrasound tests of all the patients suggested good uterine involutions, and they had no obvious complaints such as hypogastralgia. Conclusions This step-wise surgical technique of knapsack-like uterine compression sutures can compress the uterus completely. It is a technique that can conserve the uterus and fertility function without special equipment in caesarean section for PPH, with the characteristics of being safe, simple and stable (3 S) with rapid surgery, reliable hemostasis and resident doctor to operation (3R).

Abstract Background Postpartum hemorrhage is the leading cause of maternal death and severe maternal morbidity worldwide. Previous studies have reported the importance of multidisciplinary treatment approaches for postpartum hemorrhage; however, only a few studies have shown a clear improvement in maternal outcomes. Therefore, this study aimed to investigate the efficacy of a call system for postpartum hemorrhage in a tertiary emergency facility for rapid multidisciplinary treatment and its effect on maternal outcomes. Methods This single-center retrospective cohort study included patients transferred to our hospital due to postpartum hemorrhage between April 1, 2013, and March 31, 2019. The primary outcome was mortality, and the secondary outcomes were morbidity (duration of hospital stay, duration of intensive care unit stay, admission to the intensive care unit, respirator use, duration of ventilator support, acute kidney injury, transfusion-associated circulatory overload/transfusion-related acute lung injury, hysterectomy, composite adverse events, blood transfusion initiation time, blood transfusion volume, and treatment for postpartum hemorrhage). An in-hospital call system implementation commenced on April 1, 2016. The study outcomes were compared 3 years before and after implementing the call system. Results The blood transfusion initiation time and duration of hospital stay were significantly shortened after implementing the call system for postpartum hemorrhage. No maternal deaths were observed after implementing the system. Conclusions Implementing call systems specialized for postpartum hemorrhage in tertiary emergency facilities may improve maternal outcomes.

Abstract Background In this meta-analysis, we aimed to update the clinical evidence regarding the efficacy and safety of TXA in the prevention of PPH. Methods A literature search of PubMed, Scopus, Web of Science, Google Scholar, and Cochrane Library from inception until December 2022 was conducted. We included randomized controlled trials (RCTs) comparing TXA with a placebo among pregnant women. All relevant outcomes, such as total blood loss, the occurrence of nausea and/or vomiting, and changes in hemoglobin, were combined as odds ratios (OR) or mean differences (MD) in the meta-analysis models using STATA 17 MP. Results We included 59 RCTs (18,649 patients) in this meta-analysis. For cesarean birth, TXA was favored over the placebo in reducing total blood loss (MD= -2.11 mL, 95%CI [-3.09 to -1.14], P

Abstract Objective To explore the risk factors and develop a predictive model for postpartum hemorrhage in twin pregnancies. Methods All patients who gave birth at Ningbo Women and Children’s Hospital from January 2018 to August 2022 were recruited. Patients were randomly allocated to a training cohort (n $$=$$ = 1395) validation cohort (n $$=$$ = 650) at a 7:3 ratio. In the training cohort, LASSO regression for screening variables and multifactorial logistic regression analysis were performed to identify independent risk factors for postpartum hemorrhage in twin pregnancies. A nomogram was established based on the results of multiple logistic regression analysis. Nomogram performance was quantified using the receiver operating characteristic curve, Hosmer- Lemeshow test and decision curve analysis. Results A total of 2045 patients were included in this study. Multifactorial Logistic regression analysis showed maternal age, assisted reproduction, platelet count, fibrinogen level, albumin level, hypertensive disorders of pregnancy, placenta praevia, number of previous cesarean deliveries, number of previous intrauterine manipulation, and neonatal weight were independent risk factors for postpartum hemorrhage in twin births. The area under curve (AUC) for the training cohort was 0.810 [95 $$\%$$ % CI (0.781, 0.839)], with a sensitivity of 76.5 $$\%$$ % , specificity of 71.0 $$\%$$ % , and positive and negative predictive values of 0.358 and 0.935, respectively, while the AUC for the validation cohort was 0.821 [95 $$\%$$ % CI (0.781, 0.860)], with a sensitivity of 80.9 $$\%$$ % , specificity of 69.49 $$\%$$ % , and positive predictive value and negative predictive value of 0.426 and 0.929, respectively. Conclusion The predictive model can effectively and quantitatively assess the risk of postpartum hemorrhage in twin pregnancies and help clinicians to take personalized preventive measures.

Abstract Background Postpartum hemorrhage (PPH) is the leading cause of maternal death worldwide, particularly in low- and middle-income countries; however, the majority of these deaths could be avoided with adequate obstetric care. Analyzing severe maternal outcomes (SMO) has been a major approach for evaluating the quality of the obstetric care provided, since the morbid events that lead to maternal death generally occur in sequence. The objective of this study was to analyze the clinical profile, management, maternal outcomes and factors associated with SMO in women who developed PPH and were admitted to an obstetric intensive care unit (ICU) in northeastern Brazil. Methods This retrospective cohort study included a non-probabilistic, consecutive sample of postpartum women with a diagnosis of PPH who were admitted to the obstetric ICU of the Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) between January 2012 and March 2020. Sociodemographic, biological and obstetric characteristics and data regarding childbirth, the management of PPH and outcomes were collected and analyzed. The frequency of maternal near miss (MNM) and death was calculated. Multiple logistic regression analysis was performed to determine the adjusted odd ratios (AOR) and their 95% confidence intervals (95% CI) for a SMO. Results Overall, 136 cases of SMO were identified (37.9%), with 125 cases of MNM (34.9%) and 11 cases of maternal death (3.0%). The factors that remained associated with an SMO following multivariate analysis were gestational age ≤ 34 weeks (AOR = 2.01; 95% CI: 1.12–3.64; p

Abstract Background Retained products of conception (RPOC) often cause severe postpartum hemorrhage (PPH) but the clinical significance of RPOC in placenta previa is unclear. This study aimed to investigate the clinical significance of RPOC in women with placenta previa. The primary outcome was to evaluate risk factors of RPOC and the secondary outcome was to consider risk factors of severe PPH. Methods Singleton pregnant women with placenta previa who underwent cesarean section (CS) and placenta removal during the operation at the National Defense Medical College Hospital between January 2004 and December 2021 were identified. A retrospective analysis was performed to examine the frequency and risk factors of RPOC and the association of RPOC with severe PPH in pregnant women with placenta previa. Results This study included 335 pregnant women. Among these, 24 (7.2%) pregnant women developed RPOC. Pregnant women with prior CS (Odds Ratio (OR) 5.98; 95% Confidence Interval (CI) 2.35–15.20, p

Abstract Background Postpartum hemorrhage (PPH) is one of the important risk factors leading to maternal mortality and intervention is essential. Oxytocin therapy is widely used clinically, but the effect is unsatisfactory. The efficacy of tranexamic acid (TXA) in hemostasis is notable, whereas its use in preventing PPH warrants exploration. Aims To evaluate the effect of prophylactic administration of TXA on perioperative blood loss in women undergoing cesarean section by systematic review and meta-analysis of published studies. Methods Bibliographic databases were screened from their inception to December 2022 to retrieve relevant studies. Study outcomes including blood loss during cesarean section, 2-h postpartum blood loss, total blood loss (during cesarean section and 2-h postpartum), and 6-h postpartum, as well as hemoglobin changes were extracted and compared. Results A total of 21 studies, nine randomized clinical trials and 12 cohort studies, involving 1896 patients given TXA prophylactically and 1909 patients given placebo or no treatment, were analyzed. Compared with the control group, the preoperative prophylactic intravenous administration of TXA significantly reduced the intraoperative (RCT: P

Abstract Background Postpartum hemorrhage (PPH) is the global leading cause of maternal mortality, affecting nearly 3 to 6 percent of all women giving birth in India. The World Health Organization (WHO) has updated its guidelines to recommend the early use of intravenous (IV) tranexamic acid (TXA) in addition to standard care for all diagnosed PPH cases. This study aimed to assess the cost-effectiveness of introducing TXA for PPH management in the Indian public health system. Methods A decision analytic model was built using a decision tree to determine the cost-effectiveness of administering IV TXA to women experiencing PPH within 3 h of birth to existing management with uterotonics and supportive care. Using a disaggregated societal perspective, the costs and consequences for a hypothetical cohort of women experiencing PPH in public health facilities was estimated. The model was populated using probabilities, clinical parameters, and utilities from published literature, while cost parameters were largely derived from a primary economic costing study. The primary outcome of interest was the incremental cost-utility ratio (ICUR). Associated clinical events and net benefits were estimated. One-way and probabilistic sensitivity analysis (PSA) was undertaken. The budget impact was estimated for a national-level introduction. Results For an estimated annual cohort of 510,915 PPH cases in India, the addition of IV TXA would result in a per-patient disaggregated societal cost of INR 6607 (USD 95.15) with a discounted gain of 20.25 QALYs, as compared to a cost of INR 6486 (USD 93.41) with a discounted gain of 20.17 QALYs with standard care PPH management. At an ICUR value of INR 1470 per QALY gained (USD 21), the addition of IV TXA is cost-effective in Indian public health settings. The intervention is likely to prevent 389 maternal deaths, 177 surgeries, and 128 ICU admissions per 100,000 PPH cases. The findings are robust under uncertainty, with 94.5% of PSA simulations remaining cost-effective. A cumulative increase of 2.3% financial allocation for PPH management over five years will be incurred for TXA introduction. Conclusions Addition of tranexamic acid for primary PPH management, as recommended by WHO, is cost-effective in Indian public health settings. Policy guidelines, training manuals, and facility checklists should be updated to reflect this recommendation.

Abstract Background Postpartum hemorrhage remains a key contributor to overall maternal morbidity in the United States. Current clinical assessment methods used to predict postpartum hemorrhage are unable to prospectively identify about 40% of hemorrhage cases. Oxytocin is a first-line pharmaceutical for preventing and treating postpartum hemorrhage, which acts through oxytocin receptors on uterine myocytes. Existing research indicates that oxytocin function is subject to variation, influenced in part by differences in the DNA sequence within the oxytocin receptor gene. One variant, rs53576, has been shown to be associated with variable responses to exogenous oxytocin when administered during psychological research studies. How this variant may influence myometrial oxytocin response in the setting of third stage labor has not been studied. We tested for differences in the frequency of the oxytocin receptor genotype at rs53576 in relationship to the severity of blood loss among a sample of individuals who experienced vaginal birth. Methods A case–control prospective design was used to enroll 119 postpartum participants who underwent vaginal birth who were at least 37 weeks of gestation. Cases were defined by either a 1000 mL or greater blood loss or instances of heavier bleeding where parturients were given additional uterotonic treatment due to uterine atony. Controls were matched to cases on primiparity and labor induction status. Genotype was measured from a maternal blood sample obtained during the 2nd postpartum month from 95 participants. Statistical analysis included bivariate tests and generalized linear and Poisson regression modeling. Results The distribution of the genotype across the sample of 95 participants was 40% GG (n = 38), 50.5% AG (n = 48) and 9.5% AA (n = 9). Blood loss of 1000 mL or greater occurred at a rate of 7.9% for GG, 12.5% for AG and 55.6% for AA participants (p = 0.005). Multivariable models demonstrated A-carriers (versus GG) had 275.2 mL higher blood loss (95% CI 96.9–453.4, p

Abstract Background Postpartum hemorrhage (PPH) remains the leading cause of maternal death worldwide despite its often-preventable nature. Understanding health care providers’ knowledge of clinical protocols is imperative for improving quality of care and reducing mortality. This is especially pertinent in referral and teaching hospitals that train nursing and medical students and interns in addition to managing emergency and referral cases. Methods This study aimed to (1) measure health care providers’ knowledge of clinical protocols for risk assessment, prevention, and management of PPH in 3 referral hospitals in Kenya and (2) examine factors associated with providers’ knowledge. We developed a knowledge assessment tool based on past studies and clinical guidelines from the World Health Organization and the Kenyan Ministry of Health. We conducted in-person surveys with health care providers in three high-volume maternity facilities in Nairobi and western Kenya from October 2018-February 2019. We measured gaps in knowledge using a summative index and examined factors associated with knowledge (such as age, gender, qualification, experience, in-service training attendance, and a self-reported measure of peer-closeness) using linear regression. Results We interviewed 172 providers including consultants, medical officers, clinical officers, nurse-midwives, and students. Overall, knowledge was lowest for prevention-related protocols (an average of 0.71 out of 1.00; 95% CI 0.69–0.73) and highest for assessment-related protocols (0.81; 95% CI 0.79–0.83). Average knowledge scores did not differ significantly between qualified providers and students. Finally, we found that being a qualified nurse, having a specialization, being female, having a bachelor's degree and self-reported closer relationships with colleagues were statistically significantly associated with higher knowledge scores. Conclusion We found gaps in knowledge of PPH care clinical protocols in Kenya. There is a clear need for innovations in clinical training to ensure that providers in teaching referral hospitals are prepared to prevent, assess, and manage PPH. It is possible that training interventions focused on learning by doing and teamwork may be beneficial.

Abstract Introduction Maternal mortality is a health problem in developing countries and is the result of several factors such as sociodemographic and economic inequalities and difficulties in accessing the health services. In addition, training strategies in obstetric emergencies targeting the non-medical personnel such as traditional midwives are scarce. The focus of this study is to develop learning and communication bridges on the management of obstetric emergencies and on policies of patients’ referral to the biomedical health system in rural areas. Methodology A Participant Action Research (PAR) study with a mixed methods approach was set up to elaborate culturally adapted flowcharts. The project lasted approximately 3,5 years, from September 2016 to January 2021. Results The study was conducted with 94 traditional midwives from southern Ecuador and is divided into 4 phases, namely: 1) Exploration: focus groups and interviews were conducted to document the management of obstetric emergencies through the presentation of “clinical case” scenarios in three important topics, namely: pre-eclampsia, shoulder dystocia and postpartum hemorrhage, 2) Planning: a number of reflective sessions were conducted between the researchers and the healers/midwives to elaborate flowcharts. 3) Action: the training was conducted in rooms dedicated to proficiency in the aforementioned topics and using the flowcharts, 4) Evaluation: 90% of the participants reported having used the flowcharts during the first year after the training. The most frequently used flowchart was that of pre-eclampsia for the recognition of warning signs during pregnancy control. Conclusion This study documents common practices of pregnancy and delivery management by traditional midwives. Furthermore, cultural flowcharts were developed for and together with midwives to improve the clinical response to obstetric emergencies. The preliminary evaluation was favorable; the most frequently used flowchart concerned preeclampsia. In this process, establishing a partnership was crucial for successful intercultural collaboration.

Abstract Background A subsequent pregnancy after uterine artery embolization (UAE) raises several concerns, one of which is placenta accreta spectrum (PAS). Placenta previa is the strongest risk factor for PAS, which is most likely to occur in the lower uterine segment. PAS without placenta previa (i.e., uterine body PAS) is considered relatively rare. Case presentation A 35-year-old woman, gravida 2 para 1, had undergone UAE for postpartum hemorrhage due to uterine atony after vaginal delivery in her previous pregnancy. She developed placenta previa during her subsequent pregnancy and was therefore evaluated for PAS in the lower uterine segment. On the basis of examination findings, we considered PAS to be unlikely. During cesarean section, we found that the placenta was not detached from the uterine body, and the patient was determined to have uterine body PAS. Ultimately, a hysterectomy was performed. Conclusions PAS can occur in a subsequent pregnancy after UAE. When a subsequent pregnancy after UAE is accompanied by placenta previa, it is important to maintain a high index of suspicion of uterine body PAS without being misled by the presence of placenta previa.

Abstract Background The third stage of labor begins with the baby’s birth and ends with the expulsion of the placenta and embryonic membranes. The prolongation of the third stage of labor, placental retention, subsequent issues such as postpartum hemorrhage, and manual removal of the placenta have adverse outcomes, which eventually affect the positive experience of delivery. The present study aimed to assess the effect of placental cord drainage on the duration of the third stage of labor and to clarify its effects on postpartum hemorrhage, retained placenta, and incidence of manual removal of placenta. Methods This study was a parallel-group randomized trial. Four hundred women in the third stage of labor after vaginal delivery were randomized into the drainage (placenta drainage, n = 200) and the control groups (no placenta drainage, n = 200). In both groups, the third stage of labor was performed with the active method, and the placenta was removed using the Brandt-Andrews maneuver with maternal pushing. The duration of the third stage was compared between the two groups as the primary outcome. Also, the incidence of postpartum hemorrhage, retained placenta, and manual removal of placenta was compared. Results In all, 175 women in the drainage group and 165 women in the control group were included in the analysis. The third stage of labor was significantly shorter after placental cord drainage. The mean duration of the third stage was 7.09 ± 1.01 minutes in the drainage group, and it was 10.43 ± 3.20 minutes in the control group (P

Abstract Postpartum hemorrhage (PPH) is an obstetric emergency instigated by excessive blood loss which occurs frequently after the delivery. The PPH can result in volume depletion, hypovolemic shock, and anemia. This is particular condition is considered a major cause of maternal deaths around the globe. Presently, physicians utilize visual examination for calculating blood and fluid loss during delivery. Since the classical methods depend on expert knowledge and are inaccurate, automated machine learning based PPH diagnosis models are essential. In regard to this aspect, this study introduces an efficient oppositional binary crow search algorithm (OBCSA) with an optimal stacked auto encoder (OSAE) model, called OBCSA-OSAE for PPH prediction. The goal of the proposed OBCSA-OSAE technique is to detect and classify the presence or absence of PPH. The OBCSA-OSAE technique involves the design of OBCSA based feature selection (FS) methods to elect an optimum feature subset. Additionally, the OSAE based classification model is developed to include an effective parameter adjustment process utilizing Equilibrium Optimizer (EO). The performance validation of the OBCSA-OSAE technique is performed using the benchmark dataset. The experimental values pointed out the benefits of the OBCSA-OSAE approach in recent methods.

Abstract Background Postpartum hemorrhage is one of the leading causes of maternal deaths worldwide. Early recovery is a performance indicator and better health outcome of patients with postpartum hemorrhage. Therefore, this study aimed to assess time to recovery from postpartum hemorrhage and its predictors in Debre Markos Comprehensive Specialized Hospital, Ethiopia, 2020. Methods A retrospective follow-up study was conducted among 302 women who were diagnosed with postpartum hemorrhage from January 1, 2016 to December 31, 2020 at Debre Markos Comprehensive Specialized Hospital. Consecutive sampling technique was employed. To show the statistical significant difference between each group of variables, log rank test was used. Kaplan Meier analysis to estimate time to recovery and cox proportional-hazard regression analysis to determine independent predictors were carried out cautiously. Adjusted hazard ratio used to determine the strength of association. Result The median recovery time from postpartum hemorrhage was 13 h with range of (10 to 17 h). Blood transfusion (AHR: 1.8, 95% CI (1.39, 2.57)), NASG utilization (AHR: 6.5, 95% CI (4.58, 9.42)) fluid resuscitation (AHR 2.9, 95% CI (1.48, 5.54)), active management of third stage of labor (AHR: 1.7, 95% CI (1.18, 2.45)) and history of antenatal care follow-up (AHR: 2.6, 95% CI (1.91, 3.56)) were the predictors, which shorten the recovery time. Comorbidities like anemia at the time of admission (AHR: 0.62 95% CI (0.44, 0.89)), retroviral infection (AHR: 0.33, 95% CI (0.16, 0.67)) and Hepatitis B-Virus infection (AHR: 0.52, 95% CI (0.32, 0.82)) delay the recovery rate from postpartum hemorrhage. Conclusion Mothers in North-West Ethiopia stays morbid from postpartum hemorrhage for more than half a day. Their recovery time was affected by Non-Pneumatic Anti-Shock Garment utilization, implementation of emergency management components like blood transfusion and fluid resuscitation, history of antenatal care follow up, and being comorbid with viral infections. Non-pneumatic anti-shock garment application to every mother with postpartum hemorrhage and implementation of proper emergency management approach are vital for rapid recovery from postpartum hemorrhage.

Abstract Background The Japan Society of Obstetrics and Gynecology and the Japan Association of Obstetricians and Gynecologists have issued the guidelines and recommendations on postpartum hemorrhage since 2010 and have been conducted widespread educational activities from 2012. The aim of this study was to investigate the impact of these efforts by the Societies to prevent maternal deaths due to obstetric hemorrhage on trends in epidemiology and management of severe postpartum hemorrhage in Japan. Methods A national retrospective cohort study was conducted using the national database of health insurance claims for the period 2012 and 2018. The subjects were all insured women who received a blood transfusion for postpartum hemorrhage. The primary endpoints of this study were hysterectomy and maternal mortality. The etiology of hemorrhage, treatment facility, type of procedure, and blood transfusion volume were tabulated. Results Women with postpartum hemorrhage that underwent transfusion increased from 3.5 to 5.5 per 1000 deliveries between 2012 and 2018. The most common cause of postpartum hemorrhage was atonic hemorrhage. After insurance coverage in 2013, the intrauterine balloon tamponade use increased to 20.3% of postpartum hemorrhages treated with transfusion in 2018, while the proportion of hysterectomy was decreased from 7.6% (2013–2015) to 6.4% (2016–2018) (p

Abstract Background Severe obstetric hemorrhage is a leading cause of severe maternal morbidity. A perinatal blood transfusion is the key factor in the treatment of severe obstetric hemorrhage. Our aim is to identify patients with a high risk of perinatal blood transfusions before Cesarean Section, which can promote the effectiveness of the treatment of severe obstetric hemorrhage, as well as improve obstetric preparations. Methods This study retrospectively analyzed the data of 71 perinatal blood transfusion patients and 170 controls, who were both underwent Cesarean Section from July 2018 to September 2019. These data were included in the training set to build the risk prediction model of needing blood transfusion. Additionally, the data of 148 patients with the same protocol from October 2019 to May 2020 were included in the validation set for model validation. A multivariable logistic regression model was used. A risk prediction nomogram was formulated per the results of the multivariate analysis. Results The strongest risk factors for perinatal blood transfusions included preeclampsia (OR = 6.876, 95% CI: 2.226–23.964), abnormal placentation (OR = 5.480, 95% CI: 2.478–12.591), maternal age (OR = 1.087, 95% CI: 1.016–1.166), predelivery hemoglobin (OR = 0.973, 95% CI: 0.948–0.998) and predelivery fibrinogen (OR = 0.479, 95% CI: 0.290–0.759). A risk prediction model of perinatal blood transfusions for cesarean sections was developed (AUC = 0.819; sensitivity: 0.735; specificity: 0.848; critical value: 0.287). Conclusions The risk prediction model can identify the perinatal blood transfusions before Cesarean Section. With the nomogram, the model can be further quantified and visualized, and clinical decision-making can subsequently be further simplified and promoted.

Abstract Background Objective to assess the value of preoperative tranexamic acid (TXA) in reduction of intraoperative and postoperative blood loss in high-risk cesarean delivery (CD). Methods A double blind randomized controlled trial included 160 high risk women who underwent elective lower segment CD. They were equally randomized to receive either 1 g of TXA or placebo 15 min before surgery. The primary outcome was Intraoperative blood loss. Results The estimated blood loss was significantly higher in the placebo group when compared to TXA group (896.81 ± 519.6 vs. 583.23 ± 379.62 ml, P

Abstract Background Emergency obstetric care training, using Advances in Labour and Risk Management (ALARM) International Program (AIP) was implemented in Ukraine, a country with universal access to skilled perinatal and obstetric care but restricted resources. A total of 577 providers (65.5% of total) from 28 maternal clinics attended a 5-day training session focused on the five main causes of maternal mortality, with hands-on skill workshops, pre- and post- tests, and an objective structured clinical examination. The effects of this emergency obstetric care training on maternal outcomes is the subject of this paper. Methods A non-randomized controlled trial was conducted. The pilot areas where the training was implemented consisted of 64 maternity clinics of which 28 were considered as cases and 36 non-participating clinics were the referents. Data on maternal outcomes were collected for a 2-year span (2004-2005) prior to the trainings, which took place 2006-2007 and again after implementation of the trainings, from 2008 to 2009. Information was collected from 189,852 deliveries. Outcomes for the study were incidences of operative delivery and postpartum hemorrhage. Non-parametric statistics, meta-analyses, and difference in difference (DID) estimation were used to assess the effect of the AIP on maternal indices. Results DID analysis showed that after the training, compared to the referents, the cases had significant reduction of blood transfusions (OR: 0.56; 95%CI: 0.48-0.65), plasma transfusions (OR: 0.70; 95%CI: 0.63-0.78), and uterus explorations (OR: 0.64; 95%CI: 0.59-0.69). We observed a non-significant reduction of postpartum hemorrhage ≥1000 ml (OR: 0.92; 95%CI: 0.81-1.04; P = 0.103). Utilization of vacuum extraction for vaginal delivery increased (OR: 2.86; 95%CI: 1.80-4.57), as well as forceps assisted delivery (OR: 1.80; 95%CI: 1.00-3.25) and cesarean section (OR: 1.11; 95%CI: 1.06-1.17). There was no change in the occurrence of postpartum hysterectomy and maternal mortality. Conclusions After one week of Emergency Obstetrics Care training of the obstetric staff in a setting with universal access to perinatal and obstetric care but restricted resources, an association with the reduction of postpartum hemorrhage related interventions was observed. The effects on the use of vacuum extraction and cesarean section were minimal. Trial registration Retrospectively registered 071212007807 from 07/12/2012.

Objective: The purpose of this study was to evaluate the relationship of thin endometrial thickness (EMT) on the maternal and child health outcome of frozen-thawed embryo transfer (FET) cycles with singletons., Methods: The retrospective cohort study included 1,771 live singleton deliveries, with 273 in the thin endometrium group (EMT ≤ 7.5 mm) and 1,498 in the control group (EMT > 7.5 mm). Pregnancy, perinatal complications and neonatal outcomes were compared between the two groups., Results: Women in the thinner endometrium group had higher rates of preeclampsia (7.69% vs. 7.00%), placenta previa (4.39% vs. 2.43%), postpartum haemorrhage (15.38% vs. 11.42%) than the control groups, although they were not significantly different. Significant difference was observed in the rates of placental abruption (1.09% vs. 0.07%, P = 0.001), abnormal placental cord insertion (3.66% vs. 1.74%, P = 0.011), placental adherence (15.38% vs. 7.14%, P < 0.001) between the two groups. No significant difference could be found regarding preterm labour, macrosomia, Apgar ≤ 7, large for gestational age (LGA) and appropriate for gestational age (AGA), and singletons from the thinner endometrium group had a significantly lower birthweight than those from the controls. Then after adjusting for confounders, thinner endometrium was still statistically significantly associated with placental adherence, postpartum haemorrhage and low birthweight (LBW)., Conclusion: These findings highlight the important role of endometrial thickness in influencing perinatal and obstetric-neonatal outcomes in FET cycles. The study contributes to the growing body of evidence supporting the clinical relevance of endometrial thickness in FET cycles and underscores the need for close monitoring and management of pregnancies in women with a thin endometrium. Future research should focus on elucidating the underlying mechanisms and identifying effective interventions to improve endometrial thickness and pregnancy outcomes in this patient population., Competing Interests: Declarations Ethics approval and consent to participate This study was conducted in accordance with the approved guidelines and approved by the Ethics Committee of Nanjing Maternity and Child Health Care Hospital (NJFY-2021KY-111).

Abstract Background Since the effectiveness of low-dose aspirin (LDA) in twin pregnancies is uncertain, we aimed to preliminarily assess whether LDA is beneficial in preventing preeclampsia in twin pregnancies. Methods This study is an observational study in two hospitals in China. Among 932 women, 277 in the First Affiliated Hospital of Chongqing Medical University were routinely treated with aspirin (100 mg daily) from 12 to 16 weeks to 35 weeks of gestational age, while 655 in Chongqing Health Center for Women and Children were not taking aspirin during pregnancy. We followed each subject and the individual details were recorded. Results LDA significantly reduced the risk of preeclampsia (RR 0.48; 95% CI 0.24–0.95) and preterm birth 34 weeks (RR 0.50; 95% CI 0.29–0.86) and showed possible benefits to lower the rate of SGA babies (RR 0.74; 95% CI 0.55–1.00). Moreover, the risk of postpartum hemorrhage was not increased by LDA (RR 0.89; 95% CI 0.35–2.26). Conclusions Treatment with low-dose aspirin in twin pregnancies could offer some protection against adverse pregnancy outcomes in the absence of significantly increased risk of postpartum hemorrhage.

Abstract Background Postpartum hemorrhage (PPH) is a potentially fatal condition requiring urgent and appropriate intervention. Uterine artery embolization (UAE) has a high hemostatic capacity for PPH, but it may fail. Disseminated intravascular coagulation (DIC) has been reported as a risk factor associated with the failure of UAE. Case presentation A 37-year-old primigravida with dichorionic diamniotic twins and placenta previa underwent cesarean section. The blood loss during surgery was 4950 mL. Hemostasis was achieved using an intrauterine balloon tamponade device. However, she lost a further 2400 mL of blood 5 h after surgery. We embolized both uterine arteries using gelatin sponges and confirmed hemostasis. She was suffering from DIC and received ample blood transfusions. However, a further 1300 mL of blood was lost 18 h after surgery and we performed repeated UAE, with complete recanalization of the uterine arteries on both sides and re-embolization with gelatin sponges. Her DIC was treated successfully by blood transfusions at this time, and she showed no further bleeding after the repeated UAE. Conclusions DIC is a risk factor for the failure of UAE. Repeated UAE may be effective after sufficient improvement of the hematological status in patients with PPH and DIC.

Abstract Background D-dimer and fibrinogen were verified to be altered in preeclampsia. This study was to evaluate the associations of D-dimer and fibrinogen plasma levels with postpartum hemorrhage or intrauterine growth restriction in preeclamptic women. Methods This was a retrospective study that recruited 278 preeclamptic women with singleton pregnancy from January 2016 to December 2019. Patients were allocated into five groups: mild preeclampsia (mPE) (n=68), mild preeclampsia with postpartum hemorrhage (mPE+PPH) (n=13), severe preeclampsia (sPE) (n=112), severe preeclampsia with postpartum hemorrhage (sPE+PPH) (n=17) and severe preeclampsia with intrauterine growth restriction (sPE+IUGR) (n=68). The antenatal D-dimer and fibrinogen plasma levels were analyzed among the groups. Logistic regression was used to determine the correlation between serum indexes and PPH or IUGR in preeclampsia. Results The antenatal D-dimer plasma levels were significantly higher in the sPE+PPH group than that in the sPE group (2.02 μg/ml versus 1.37 μg/ml, P = 0.001), but there was no difference in fibrinogen. Elevated D-dimer was associated with PPH among severe preeclamptic women (adjusted odds ratio (aOR) [95% CI]: 3.093 [1.527-6.264], P = 0.002). No differences in D-dimer and fibrinogen were found between the mPE and mPE+PPH groups or between the sPE and sPE+IUGR groups. Conclusions Elevated antenatal plasma D-dimer level may be associated with postpartum hemorrhage in severe preeclampsia, but not with intrauterine growth restriction. Future prospective clinical trials are needed to investigate the predictive value of D-dimer in postpartum hemorrhage in severe preeclampsia.

Abstract Background Postpartum hemorrhage (PPH) is the leading cause of maternal mortality in low-income countries, and is the most common direct cause of maternal deaths in Madagascar. Studies in Madagascar and other low-income countries observe low provider adherence to recommended practices for PPH prevention and treatment. Our study addresses gaps in the literature by applying a behavioral science lens to identify barriers inhibiting facility-based providers’ consistent following of PPH best practices in Madagascar. Methods In June 2019, we undertook a cross-sectional qualitative research study in peri-urban and rural areas of the Vatovavy-Fitovinany region of Madagascar. We conducted 47 in-depth interviews in 19 facilities and five communities, with facility-based healthcare providers, postpartum women, medical supervisors, community health volunteers, and traditional birth attendants, and conducted thematic analysis of the transcripts. Results We identified seven key behavioral insights representing a range of factors that may contribute to delays in appropriate PPH management in these settings. Findings suggest providers’ perceived low risk of PPH may influence their compliance with best practices, subconsciously or explicitly, and lead them to undervalue the importance of PPH prevention and monitoring measures. Providers lack clear feedback on specific components of their performance, which ultimately inhibits continuous improvement of compliance with best practices. Providers demonstrate great resourcefulness while operating in a challenging context with limited equipment, supplies, and support; however, overcoming these challenges remains their foremost concern. This response to chronic scarcity is cognitively taxing and may ultimately affect clinical decision-making. Conclusions Our study reveals how perception of low risk of PPH, limited feedback on compliance with best practices and consequences of current practices, and a context of scarcity may negatively affect provider decision-making and clinical practices. Behaviorally informed interventions, designed for specific contexts that care providers operate in, can help improve quality of care and health outcomes for women in labor and childbirth.

Abstract Background Although maternal deaths are rare in developed regions, the morbidity associated with severe postpartum hemorrhage (SPPH) remains a major problem. To determine the prevalence and risk factors of SPPH, we analyzed data of women who gave birth in Guangzhou Medical Centre for Critical Pregnant Women, which received a large quantity of critically ill obstetric patients who were transferred from other hospitals in Southern China. Methods In this study, we conducted a retrospective case-control study to determine the prevalence and risk factors for SPPH among a cohort of women who gave birth after 28 weeks of gestation between January 2015 and August 2019. SPPH was defined as an estimated blood loss ≥1000 mL and total blood transfusion≥4 units. Logistic regression analysis was used to identify independent risk factors for SPPH. Results SPPH was observed in 532 mothers (1.56%) among the total population of 34,178 mothers. Placenta-related problems (55.83%) were the major identified causes of SPPH, while uterine atony without associated retention of placental tissues accounted for 38.91%. The risk factors for SPPH were maternal age

Abstract Background To assess the efficacy and safety of bilateral-contralateral cervix clamp firstly applied in postpartum hemorrhage caused by uterine tony of lower segment. Methods Totally 47 pregnant women with postpartum hemorrhage secondary to lower uterine segment atony in vaginal delivery or after caesarean delivery were included from March 1, 2020 to May 31, 2020. According to patient’s informed consent, 22 women accepted cervical clamp to treat and 25 only used uterotonics in control group. Then hemostatic efficacy and safety of bilateral-contralateral cervix clamp were assessed by retrospective analysis. Results It was found that mean blood loss in clamp group was much less during vaginal delivery (656.2±72.79 g vs 811.8±86.07 g, p = 0.001) or after caesarean delivery (42.8±6.60 g vs 126.3±86.97 g, p = 0.007), and incidence of uterotonic repeated usage (81.8% vs 36, 18.2% vs 64%, p = 0.001) or side effect (18.2% vs 48.0%, p = 0.031) appeared less than control group, but there was no statistical differences on hospital stay (4.1±1.57 days vs 3.8±1.61 days, p = 0.535), hemoglobin (119±4.10 g vs 121.4±4.19 g, p = 0.058), blood transfusion (9.1% vs 12%,p = 0.746), surgical procedures (4.5% vs 4.0%, p = 0.93), also no clamp complications occurred. Conclusions The bilateral-contralateral cervix clamp was effective and safe, this new technique could be a complementary treatment for postpartum hemorrhage.

Abstract Background A bicornuate uterus often results in infertility. While reconstructive procedures may facilitate pregnancy, spontaneous abortion or serious pregnancy complications may occur. We present a case of a bicornuate uterus with spontaneous conception after Strassman metroplasty; however, life-threatening complications during pregnancy occurred. Case presentation : A 38-year-old woman with a history of infertility presented for prenatal care at 6 weeks of gestation. She had conceived spontaneously after four failed in vitro fertilization and embryo transfer (IVF-ET) procedures, Strassman metroplasty for a complete bicornuate uterus, and two postoperative IVF-ET pregnancies that ended in embryo arrest. This pregnancy was uneventful until the patient presented with massive vaginal bleeding at 28 weeks of gestation and was diagnosed with placenta previa and placenta percreta. Bleeding was controlled after emergency Caesarean section and delivery of a healthy neonate. However, severe adhesions were noted as well as a rupture along the metroplasty scar. Two days later, on removal of the intrauterine gauze packing, severe hemorrhage resumed, and the uterus did not respond to oxytocin, hemabate, or carbetocin. Emergency hysterectomy was required. Conclusions Reconstructive surgical procedures for complete bicornuate uterus may allow patients to achieve spontaneous pregnancies. However, potential intrapartum complications include placenta implantation and postpartum hemorrhage, and the latter may be exacerbated as the uterus does not contract or respond to oxytocin or prostaglandin drugs. Patients should be counseled on the risks associated with pregnancy after Strassman metroplasty, and clinicians must be aware of potential severe complications.

Abstract Background Reduction of maternal mortality and morbidity is a major global health priority. However, much remains unknown regarding factors associated with postpartum hemorrhage (PPH) among childbearing women in the Rwandan context. The aim of this study is to explore the influencing factors for prevention of PPH and early detection of childbearing women at risk as perceived by beneficiaries and health workers in the Northern Province of Rwanda. Methods A qualitative descriptive exploratory study was drawn from a larger sequential exploratory-mixed methods study. Semi‐structured interviews were conducted with 11 women who experienced PPH within the 6 months prior to interview. In addition, focus group discussions were conducted with: women’s partners or close relatives (2 focus groups), community health workers (CHWs) in charge of maternal health (2 focus groups) and health care providers (3 focus groups). A socio ecological model was used to develop interview guides describing factors related to early detection and prevention of PPH in consideration of individual attributes, interpersonal, family and peer influences, intermediary determinants of health and structural determinants. The research protocol was approved by the University of Rwanda, College of Medicine and Health Sciences Institutional Ethics Review Board. Results We generated four interrelated themes: (1) Meaning of PPH: beliefs, knowledge and understanding of PPH: (2) Organizational factors; (3) Caring and family involvement and (4) Perceived risk factors and barriers to PPH prevention. The findings from this study indicate that PPH was poorly understood by women and their partners. Family members and CHWs feel that their role for the prevention of PPH is to get the woman to the health facility on time. The main factors associated with PPH as described by participants were multiparty and retained placenta. Low socioeconomic status and delays to access health care were identified as the main barriers for the prevention of PPH. Conclusions Addressing the identified factors could enhance early prevention of PPH among childbearing women. Placing emphasis on developing strategies for early detection of women at higher risk of developing PPH, continuous professional development of health care providers, developing educational materials for CHWs and family members could improve the prevention of PPH. Involvement of all levels of the health system was recommended for a proactive prevention of PPH. Further quantitative research, using case control design is warranted to develop a screening tool for early detection of PPH risk factors for a proactive prevention.

Abstract Background Delivery methods are associated with postpartum hemorrhage (PPH) both in nulliparous and multiparous women. However, few studies have examined the difference in this association between nulliparous and multiparous women. This study aimed to explore the difference of maternal and neonatal characteristics and delivery methods between Chinese nulliparous and multiparous women, and then examine the differential effects of different delivery methods on PPH between these two-type women. Methods Totally 151,333 medical records of women who gave birth between April 2013 to May 2016 were obtained from the electronic health records (EHR) in a northern province, China. The severity of PPH was estimated and classified into blood loss at the level of 2100 ml. Neonatal and maternal characteristics related to PPH were derived from the same database. Multiple ordinal logistic regression was used to estimate associations. Results Medical comorbidities, placenta previa and accreta were higher in the nulliparous group and the episiotomy rate was higher in the multiparous group. Compared with spontaneous vaginal delivery (SVD), the adjusted odds (aOR) for progression to severe PPH due to the forceps-assisted delivery was much higher in multiparous women (aOR: 9.32; 95% CI: 3.66–23.71) than in nulliparous women (aOR: 1.70; 95% CI: 0.91–3.18). The (aOR) for progression to severe PPH due to cesarean section (CS) compared to SVD was twice as high in the multiparous women (aOR: 4.32; 95% CI: 3.03–6.14) as in the nulliparous women (aOR: 2.04; 95% CI: 1.40–2.97). However, the (aOR) for progression to severe PPH due to episiotomy compared to SVD between multiparous (aOR: 1.24; 95% CI: 0.96–1.62) and nulliparous women (aOR: 1.55; 95% CI: 0.92–2.60) was not significantly different. The (aOR) for progression to severe PPH due to vacuum-assisted delivery compared to SVD in multiparous women (aOR: 2.41; 95% CI: 0.36–16.29) was not significantly different from the nulliparous women (aOR: 1.05; 95% CI: 0.40–2.73). Conclusions Forceps-assisted delivery and CS methods were found to increase the risk of severity of the PPH. The adverse effects were even greater for multiparous women. Episiotomy and the vacuum-assisted delivery, and SVD were similar to the risk of progression to severe PPH in either nulliparous or multiparous women. Our findings have implications for the obstetric decision on the choice of delivery methods, maternal and neonatal health care, and obstetric quality control.

Abstract Background Limited data exists regarding the pregnancy and infant outcomes of Acute Fatty Liver of Pregnancy (AFLP). Methods Retrospectively collected mothers with AFLP and mothers without AFLP in our center from 1/2008 to 6/2018. The primary assessment was to analyze and compare the frequency of negative maternal and fetal outcomes. The secondary assessment was to investigate the role of intrauterine balloon tamponade in reducing negative maternal outcomes. Results Compared to 220 matched mothers, 55 AFLP mothers were younger (P

Abstract Background Previous community-based research shows that secondary prevention of postpartum hemorrhage (PPH) with misoprostol only given to women with above-average measured blood loss produces similar clinical outcomes compared to routine administration of misoprostol for prevention of PPH. Given the difficulty of routinely measuring blood loss for all deliveries, more operational models of secondary prevention are needed. Methods This cluster-randomized, non-inferiority trial included women giving birth with nurse-midwives at home or in Primary Health Units (PHUs) in rural Egypt. Two PPH management approaches were compared: 1) 600mcg oral misoprostol given to all women after delivery (i.e. primary prevention, current standard of care); 2) 800mcg sublingual misoprostol given only to women with 350-500 ml postpartum blood loss estimated using an underpad (i.e. secondary prevention). The primary outcome was mean change in pre- and post-delivery hemoglobin. Secondary outcomes included hemoglobin ≥2 g/dL and other PPH interventions. Results Misoprostol was administered after delivery to 100% (1555/1555) and 10.7% (117/1099) of women in primary and secondary prevention clusters, respectively. The mean drop in pre- to post-delivery hemoglobin was 0.37 (SD: 0.91) and 0.45 (SD: 0.76) among women in primary and secondary prevention clusters, respectively (difference adjusted for clustering = 0.01, one-sided 95% CI:

Abstract Background Postpartum haemorrhage from vaginal lacerations can occasionally be refractory to suturing and vaginal packing. Bakri uterine balloon has been widely adopted to stop uterine bleeding, but its use to stop bleeding in vaginal lacerations and its possible complications have seldom been reported. Case presentation We report a patient who had vacuum delivery for fetal distress and subsequently had postpartum hemorrhage due to previous caesarean uterine scar rupture and multiple vaginal lacerations. The severe bleeding persisted despite total abdominal hysterectomy, pelvic embolization and vaginal gauze packing, but was finally controlled by a Bakri balloon tamponade inserted into the vagina. The patient suffered from severe stress incontinence after delivery. The possible use of balloon tamponade in vaginal lacerations and the different types of vaginal balloons that are available in the market for this purpose are reviewed. The possible causes leading to stress incontinence is reported to alert the obstetrician that such management is not free of complications. Conclusion The use of Bakri balloon can help to control bleeding in severe vaginal lacerations that are unresponsive to traditional vaginal gauze packing. Further studies are needed to evaluate the risks of stress incontinence as a possible complication of vaginal balloon tamponade.

Abstract Background Postpartum hemorrhage (PPH) is a preventable complication, however, it remains being the leading cause of maternal mortality and morbidity worldwide including Thailand. Methods A case-control study to examine the risk factors associated with PPH across the hospitals under the Ministry of Public Health in Thailand, was conducted. A total of 1833 patient birth records and hospital profiles including human and physical resources from 14 hospitals were obtained. A multiple logistic regression was used identifing the factors that are significantly associated with PPH. Results The results show that the rate of PPH varied across the hospitals ranging from 1.4 to 10.6%. Women with past history of PPH were more likely to have increased risk of having PPH by 10.97 times (95% CI 2.27,53.05) compared to those who did not. The odds of PPH was higher in district and general hospitals by 14 (95% CI 3.95,50.04) and 7 (95% CI 2.27,23.27) times respectively, compared to regional hospitals. The hospitals which had inadequate nurse midwife to patient ratio (OR 2.31,95% CI 1.08,4.92), lacked nurse midwives with working experience of 6–10 years (OR 2.35, 95% CI 1.41,3.92), as well as inadequate equipment and supplies for emergency obstetric care (OR 6.47, 95% CI 1.93,21.63), had significantly higher incidence of having PPH, respectively. Conclusions This study provides interesting information that the rate of PPH varies across the hospitals in Thailand, in particular where essential nurse midwives, equipment, and supplies are limited. Therefore, improving health care services by allocating sufficient human and physical resources would contribute to significantly reduce this complication.

Abstract Background Gestational diabetes mellitus is a leading medical condition woman encounter during pregnancy with serious short- and long-term consequences for maternal morbidity. However, limited evidence was available on potential impacts of gestational diabetes mellitus using updated international diagnostic criteria on adverse maternal outcomes. Therefore, this study aimed to assess the effects of gestational diabetes mellitus on the risk of adverse maternal outcomes in Northwest Ethiopia. Methods A prospective cohort study was conducted among pregnant women followed from pregnancy to delivery. Gestational diabetes mellitus status was determined by using a two-hour 75 g oral glucose tolerance test and based on updated international diagnostic criteria. Multivariable log-binomial model was used to examine the effects of gestational diabetes mellitus on the risk of adverse maternal outcomes. Results A total of 694 women completed the follow-up and included in the analysis. Women with gestational diabetes mellitus had a higher risk of composite adverse maternal outcome (ARR=1.58, 95% CI: 1.22, 2.04), caesarean delivery (ARR=1.67; 95%: 1.15, 2.44), pregnancy induced hypertension (ARR= 3.32; 95%: 1.55, 7.11), premature rupture of membranes (ARR= 1.83; 95%: 1.02, 3.27), antepartum hemorrhage (ARR= 2.10; 95%: 1.11, 3.98) and postpartum hemorrhage (ARR= 4.85; 95%:2.28, 10.30) compared to women without gestational diabetes mellitus. Conclusions Gestational diabetes mellitus increased the risk of adverse maternal outcomes. This implies that maternal care and intervention strategies relating to women with gestational diabetes mellitus should be strengthened.

Abstract Background Twin pregnancy has a high risk for developing uterine atony (UA). This study aimed to evaluate efficacy and clinical outcomes of prophylactic compression sutures to treat UA during twin cesarean section (CS). Methods All patient records of twin deliveries by CS after gestational age of 24 weeks in a large maternity hospital in South Korea between January 2013 and June 2018 were reviewed. Patients with monochorionic monoamniotic twins were excluded from data analysis. In total, 953 women were eligible for data analysis. Results Of the 953 patients, compression sutures were applied to 147 cases with postpartum bleeding that were refractory to uterine massage and uterotonics. Out of the 147, two patients (1.4%) proceeded to additional uterine artery ligation to achieve hemostasis, yielding a success rate of 98.6%. The rate of transfusion after the first 24 h of delivery in the suture group was not significantly different from that in the non-suture group, suggesting that both groups achieved hemostasis at an equal rate after the first 24 h of delivery. The difference in the operation time between the two groups was only 8.5 min. The rate of subsequent pregnancy among the patients who received compression sutures was 44.4%. Conclusions Overall, our findings suggest that with early and fast implementation of compression sutures, UA can be treated in the setting of twin cesarean delivery without significantly increasing maternal morbidity.

Abstract Background Postpartum hemorrhage (PPH) is the leading cause of maternal death in Tanzania. The Every Second Matters for Mothers and Babies- Uterine Balloon Tamponade (ESM-UBT) device was developed to address this problem in women with atonic uterus. The objective of this study was to understand the barriers and facilitators to optimal use of the device, in Dar es Salaam Tanzania 1 year after implementation. Methods Semi-structured interviews of skilled-birth attendants were conducted between May and July 2017. Interviews were recorded, coded and analyzed for emergent themes. Results Among the participants, overall there was a positive perception of the ESM-UBT device. More than half of participants reported the device was readily available and more than 1/3 described ease and success with initial use. Barriers included fear and lack of refresher training. Finally, participants expressed a need for training and device availability at peripheral hospitals. Conclusion The implementation and progression to optimal use of the ESM-UBT device in Tanzania is quite complex. Ease of use and the prospect of saving a life/preserving fertility strongly promoted use while fear and lack of high-level buy-in hindered utilization of the device. A thorough understanding and investigation of these facilitators and barriers are required to increase uptake of the ESM-UBT device.

Abstract Background An antifibrinolytic agent that blocks lysine-binding sites on plasminogen molecules, tranexamic acid reduces bleeding-related mortality in women with postpartum hemorrhage (PPH), especially administered fairly soon after delivery. According to the randomized controlled trials thus far reported for PPH prevention after cesarean deliveries (n = 16), women who received tranexamic acid had significantly less postpartum blood loss and no increase in severe adverse effects. These were, however, primarily small single-center studies that had fundamental methodological flaws. Multicenter randomized controlled trials with adequate power are necessary to demonstrate its value persuasively before tranexamic acid goes into widespread use for the prevention of PPH after cesarean deliveries. Methods/design This study will be a multicenter, double-blind, randomized controlled trial with two parallel groups including 4524 women with cesarean deliveries before or during labor, at a term ≥34 weeks, modeled on our previous study of tranexamic acid administered after vaginal deliveries. Treatment (either tranexamic acid 1 g or placebo) will be administered intravenously just after birth. All women will also receive a prophylactic uterotonic agent. The primary outcome will be the incidence of PPH, defined by a calculated estimated blood loss > 1000 mL or a red blood cell transfusion before day 2 postpartum. This study will have 80% power to show a 20% reduction in the incidence of PPH, from 15.0 to 12.0%. Discussion As an, inexpensive, easy to administer drug that can be add to the routine management of cesarean births in delivery rooms, tranexamic acid is a promising candidate for preventing PPH after these births. This large, adequately powered, multicenter randomized placebo-controlled trial seeks to determine if the benefits of the routine prophylactic use of tranexamic acid after cesarean delivery significantly outweigh its risks. Trial registration ClinicalTrials.gov NCT03431805 (February 12, 2018).

Abstract Background Obstetric hemorrhage is one of the most common causes of obstetrical morbidity and mortality, and transfusion is the most important management for hemorrhage. The aim of our study was to investigate the pre-pregnancy and pregnancy risk factors for peripartum transfusion. Methods Women who delivered a baby from 2010 to 2014 in Korea and participated in the Korean National Health Screening Program for Infants and Children were included. To analyze pre-pregnant risk factors for peripartum transfusion, an additional analysis was done for women who underwent a National Health Screening Examination within 1 year before pregnancy, including maternal waist circumference, body mass index, blood pressure, laboratory tests and history of smoking. Multivariable logistic regression analysis was used to estimate the risk factors for peripartum transfusion. Results Of the total 1,980,126 women who met the inclusion criteria, 36,868 (1.86%) were transfused at peripartum. In a multivariable regression model, the pregnancy risk factors for peripartum transfusion included maternal age above 35 years [odds ratio (OR): 1.41; 95% confidence interval (CI): 1.32–1.50], preterm birth (OR: 2.39; 95% CI: 2.15–2.65), and maternal hypertension (OR: 2.49; 95% CI: 2.24–2.77). Pre-pregnancy risk factors including fasting glucose level of more than 126 mg/dL (OR: 1.11; 95% CI: 1.02–1.20), current-smoker status (OR: 1.20; 95% CI: 1.06–1.37), and waist-circumference less than 80 cm (OR: 1.18; 95% CI: 1.06–1.30) were independently associated with peripartum blood transfusion. Conclusions Several pre-pregnancy and pregnancy risk factors were associated with peripartum blood transfusion. Some identified factors are modifiable before conception, and our study validated peripartum blood transfusion as a form of triage.

BackgroundHemorrhage is the leading cause of maternal mortality in Bangladesh, the majority of which is due to postpartum hemorrhage (PPH), blood loss of 500 mL or more. Many deaths due to PPH occur at home where approximately 77% of births take place. This paper aims to determine whether the attendant at home delivery (i.e. traditional birth attendant (TBA) trained on PPH interventions, TBA not trained on interventions, or lay attendant) is associated with the use of interventions to prevent PPH at home births.MethodsData come from operations research to determine the safety, feasibility, and acceptability of scaling-up community-based provision of misoprostol and an absorbent delivery mat in rural Bangladesh. Analyses were done using data from antenatal care (ANC) cards of women who delivered at home without a skilled attendant (N =66,489). Multivariate logistic regression was used to assess the likelihood of using the interventions.ResultsOverall, 67% of women who delivered at home without a skilled provider used misoprostol and the delivery mat (the interventions). Women who delivered at home and had a trained TBA present had 2.72 (95% confidence interval, 2.15-3.43) times the odds of using the interventions compared to those who had a lay person present. With each additional ANC visit (maximum of 4) a woman attended, the odds of using the interventions increased 2.76 times (95% confidence interval, 2.71-2.81). Other sociodemographic variables positively associated with use of the interventions were age, secondary or higher education, and having had a previous birth.ConclusionFindings indicate that trained TBAs can have a significant impact on utilization of interventions to prevent PPH in home births. ANC visits can be an important point of contact for knowledge transfer and message reinforcement about PPH prevention.

BackgroundBangladesh is one of the few countries that may actually achieve the fifth Millennium Development Goal (MDG) in time, despite skilled birth attendance remaining low. The purpose of this paper is to examine the potential role misoprostol can play in the decline of maternal deaths attributed to postpartum hemorrhage (PPH) in Bangladesh.MethodsUsing data from a misoprostol and blood loss measurement tool feasibility study in Bangladesh, observed cause specific maternal mortality ratios (MMRs) were estimated and contrasted with expected ratios using estimates from the Bangladesh Maternal Mortality Survey (BMMS) data. Using Crystal Ball 7 we employ Monte Carlo simulation techniques to estimate maternal deaths in four scenarios, each with different levels of misoprostol coverage. These scenarios include project level misoprostol coverage (69%), no (0%), low (40%), and high (80%) misoprostol coverage. Data on receipt of clean delivery kit, use of misoprostol, experience of PPH, and cause of death were used in model assumptions.ResultsUsing project level misoprostol coverage (69%), the mean number of PPH deaths expected was 40 (standard deviation = 8.01) per 100,000 live births. Assuming no misoprostol coverage (0%), the mean number of PPH deaths expected was 51 (standard deviation = 9.30) per 100,000 live births. For low misoprostol coverage (40%), the mean number of PPH deaths expected was 45 (standard deviation = 8.26) per 100,000 live births, and for high misoprostol coverage (80%), the mean number of PPH deaths expected was 38 (standard deviation = 7.04) per 100,000 live births.ConclusionThis theoretical exercise hypothesizes that prophylactic use of misoprostol at home births may contribute to a reduction in the risk of death due to PPH, in addition to reducing the incidence of PPH. If findings from this modeling exercise are accurate and uterotonics can prevent maternal death, misoprostol could be the tool countries need to further reduce maternal mortality at home births.

Abstract Background Primary postpartum hemorrhage (PPH) is an obstetric emergency caused by excessive blood loss that occurs most commonly after the placenta is delivered. PPH can lead to volume depletion, hypovolemic shock, anemia, and it is the leading cause of maternal mortality worldwide. With 470 deaths per 100,000 live births, the maternal mortality ratio in Ethiopia is one of the highest in the world. It is estimated that 94% of births occur at home in Ethiopia and that 10% of maternal deaths are attributed to PPH. Currently, physicians use visual estimation to calculate blood loss and provide fluid during delivery. This traditional method is subjective and generally inaccurate. Method In this project, after delivery blood loss measurement system integrated with fluid delivery and vital sign monitoring method is proposed. The collection and measurement system collects blood loss after delivery and measures the amount of blood loss. The management system continuously monitors the mother’s heart rate and blood pressure. These vital sign values are integrated with the measured blood loss to estimate the amount of IV fluid required to be delivered for the mother. The rate of IV fluid delivery is regulated by a flow rate sensor and solenoid valve. Results The prototype was built and undergone through different tests and iterations. The proposed device was tested for accuracy, cost effectiveness and ease to use. 91.28% accuracy has been achieved and the prototype was built with less than 210 USD. Conclusion The proposed design allows physicians, especially those in low resource setting, to estimate blood loss and deliver fluid accurately. This helps to reduce maternal mortality rate that may occur due to postpartum hemorrhage.
