Abstract
PURPOSE To determine maternal outcomes and risk factors for composite maternal morbidity following uterine rupture during pregnancy. METHODS A retrospective cohort study including all women diagnosed with uterine rupture during pregnancy, between 2011 and 2023, at a single-center. Patients with partial uterine rupture or dehiscence were excluded. We compared women who had composite maternal morbidity following uterine rupture to those without. Composite maternal morbidity was defined as any of the following: maternal death; hysterectomy; severe postpartum hemorrhage; disseminated intravascular coagulation; injury to adjacent organs; admission to the intensive care unit; or the need for relaparotomy. The primary outcome was risk factors associated with composite maternal morbidity following uterine rupture. The secondary outcome was the incidence of maternal and neonatal complications following uterine rupture. RESULTS During the study period, 147,037 women delivered. Of them, 120 were diagnosed with uterine rupture. Among these, 44 (36.7%) had composite maternal morbidity. There were no cases of maternal death and two cases of neonatal death (1.7%); packed cell transfusion was the major contributor to maternal morbidity [occurring in 36 patients (30%)]. Patients with composite maternal morbidity, compared to those without, were characterized by: increased maternal age (34.7 vs. 32.8 years, p = 0.03); lower gestational age at delivery (35 + 5 vs. 38 + 1 weeks, p = 0.01); a higher rate of unscarred uteri (22.7% vs. 2.6%, p < 0.01); and rupture occurring outside the lower uterine segment (52.3% vs. 10.5%, p < 0.01). CONCLUSION Uterine rupture entails increased risk for several adverse maternal outcomes, though possibly more favorable than previously described. Numerous risk factors for composite maternal morbidity following rupture exist and should be carefully assessed in these patients.

Int J Obstet Anesth 2024; 58:103957. [PMID: 38071128 DOI: 10.1016/j.ijoa.2023.103957] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Revised: 10/05/2023] [Accepted: 11/15/2023] [Indexed: 05/07/2024]
Abstract
BACKGROUND The Shock Index (SI), defined as heart rate divided by systolic blood pressure, is reportedly an early surrogate indicator for postpartum hemorrhage (PPH). However, most previous studies have used clinical data of women who delivered vaginally. Therefore, we aimed to evaluate the SI pattern during cesarean delivery and determine its usefulness in detecting PPH. METHODS This was a single-center retrospective study using the clinical data of women (n = 331) who underwent cesarean delivery under spinal anesthesia at term between 2018 and 2021. We assessed the SI pattern stratified by total blood loss and evaluated the predictive performance of each vital sign in detecting PPH (total blood loss ≥1000 mL) based on the area under the receiver operating characteristic curve (AUROC). RESULTS At 10-15 min after delivery, the mean SI peaked between 0.84 and 0.90 and then decreased to a level between 0.72 and 0.77, which was similar to that upon entering the operating room. Among 331 women, 91 (27.5%) were diagnosed with PPH. There was no correlation between SI and total blood loss (rs = 0.02). The SI had low ability to detect PPH (AUROC 0.54, 95% confidence interval 0.47 to 0.61), which was similar to other vital signs (AUROCs 0.53-0.56). CONCLUSION We determined the pattern of SI during cesarean delivery. We found no correlation between SI and total blood loss. Unlike in vaginal delivery, the prognostic accuracy of SI for PPH detection in cesarean delivery was low.

Front Pharmacol 2024; 15:1361953. [PMID: 38698824 PMCID: PMC11063911 DOI: 10.3389/fphar.2024.1361953] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Accepted: 04/08/2024] [Indexed: 05/05/2024] Open
Abstract
Background For cesarean delivery (CD), the 90% effective dosage (ED90) of oxytocin for a first bolus has been established. It is not yet known how much oxytocin to inject into obese women undergoing elective discectomy to keep their uterine tone (UT) appropriate. We hypothesized that patients who are overweight need a greater dose of oxytocin infusion; thus, we aimed to determine how the dose-response curve for oxytocin infusion changes following an initial 1 international unit (IU) bolus in obese women undergoing elective CD. Methods One hundred parturients with a body mass index (BMI) greater than 30 kg/m2 were randomly assigned to receive an infusion rate of 14, 18, 22, or 26 IU/h of oxytocin. When the uterine palpation is as hard as touching the forehead or tip of the nose, it is considered sufficient UT according to the criteria used by obstetricians. The median effective dose (ED50) and ED90 values were determined using probit analysis. Results We found the ED50 and ED90 values for the infusion dose of oxytocin were around 11.0 IU/h and 19.1 IU/h, respectively. Each group had a different number of parturients who needed rescued oxytocin: 14 IU/h for six, 18 IU/h for three, one for 22 IU/h, and none for 26 IU/h. The correlation between the frequency of rescued oxytocin administration and the amount of oxytocin infusion needed to avoid uterine atony was statistically significant (p = 0.02). Conclusion The present research showed that the most effective dosage of oxytocin infusion for obese parturients undergoing elective CD is 19.1 IU/h, following an initial loading dose of 1 IU. Patients with obesity should receive a greater dosage of prophylactic oxytocin, and further studies comparing patients with and without obesity (with higher BMI) are required.

Perioperative outcomes and causes of postpartum hemorrhage in patients undergoing cesarean delivery in Thailand: A comprehensive retrospective study. PLoS One 2024; 19:e0300620. [PMID: 38626161 PMCID: PMC11020384 DOI: 10.1371/journal.pone.0300620] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Accepted: 03/03/2024] [Indexed: 04/18/2024] Open
Abstract
BACKGROUND This study aimed to identify the characteristics, causes, perioperative anesthetic, and obstetric outcomes of patients experiencing postpartum hemorrhage (PPH) after cesarean delivery. METHODS We retrospectively analyzed patients who underwent cesarean delivery at the largest university hospital in Bangkok, Thailand, during a 5-year period (January 1, 2016-December 31, 2020). PPH was defined as an estimated blood loss (EBL) of ≥ 1000 ml within 24 hours postpartum. RESULTS Of 17 187 cesarean deliveries during the study period, 649 patients were included for analysis. The mean EBL was 1774.3 ± 1564.4 ml (range: 1000-26 000 ml). Among the patients, 166 (25.6%) experienced massive PPH (blood loss > 2000 ml). Intraoperative blood transfusions were necessary for 264 patients (40.7%), while 504 individuals (77.7%) needed intraoperative vasopressors. The analysis revealed uterine atony as the leading cause of PPH in 62.7% (n = 407) of the patients, with abnormal placentation following at 29.3% (n = 190). Abnormal placentation was associated with a significantly higher mean EBL of 2345.0 ± 2303.9 ml compared to uterine atony, which had a mean EBL of 1504.0 ± 820.7 ml (P < 0.001). Abnormal placentation also significantly increased the likelihood of blood transfusions and hysterectomies (P < 0.001 for both) and led to more intensive care unit admissions (P = 0.032). The risk of EBL exceeding 2000 ml was markedly higher in patients with abnormal placentation (odds ratio [OR] 5.12, 95% confidence interval [CI] 3.45-7.57, P < 0.001) and in cases involving trauma to the internal organs (OR 2.33, 95% CI 1.16-4.71, P = 0.018) than in patients with uterine atony. The study documented three instances of perioperative cardiac arrest, one of which was fatal. CONCLUSIONS These findings highlight the importance of comprehensive perioperative management strategies, including the ready availability of adequate blood and blood products, particularly in scenarios predisposed to significant hemorrhage.

Abstract
INTRODUCTION Pregnant women with a fibrinogen level <2 g/L represent a high-risk group that is associated with severe postpartum hemorrhage and other complications. Women who would qualify for fibrinogen therapy are not yet identified. MATERIAL AND METHODS A population-based cross-sectional study was conducted using the UK Obstetric Surveillance System between November 2017 and October 2018 in any UK hospital with a consultant-led maternity unit. Any woman pregnant or immediately postpartum with a fibrinogen <2 g/L was included. Our aims were to determine the incidence of fibrinogen <2 g/L in pregnancy, and to describe its causes, management and outcomes. RESULTS Over the study period 124 women with fibrinogen <2 g/L were identified (1.7 per 10 000 maternities; 95% confidence interval 1.4-2.0 per 10 000 maternities). Less than 5% of cases of low fibrinogen were due to preexisting inherited dysfibrinogenemia or hypofibrinogenemia. Sixty percent of cases were due to postpartum hemorrhage caused by placental abruption, atony, or trauma. Amniotic fluid embolism and placental causes other than abruption (previa, accreta, retention) were associated with the highest estimated blood loss (median 4400 mL) and lowest levels of fibrinogen. Mortality was high with two maternal deaths due to massive postpartum hemorrhage, 27 stillbirths, and two neonatal deaths. CONCLUSIONS Fibrinogen <2 g/L often, but not exclusively, affected women with postpartum hemorrhage due to placental abruption, atony, or trauma. Other more rare and catastrophic obstetrical events such as amniotic fluid embolism and placenta accreta also led to low levels of fibrinogen. Maternal and perinatal mortality was extremely high in our cohort.

Abstract
Objective To investigate the use of a virtual reality learning environment (VRLE) to enhance medical student knowledge of postpartum hemorrhage (PPH) emergency management and insertion of a postpartum balloon. Methods A randomized control trial involving medical students from University College Dublin, Ireland. Participants were randomly allocated to the intervention group (VRLE tutorial) or control group (PowerPoint tutorial on the same topic). All participants completed pre-learning experience and post-learning experience surveys. Both groups were timed and assessed on postpartum balloon insertion technique on a model pelvis. The primary outcome was assessment of student knowledge. Secondary outcomes included confidence levels, time taken to complete the task, technique assessment, satisfaction with the learning environment, and side effects of VR. Results Both learning experiences significantly (p < 0.001) enhanced student performance on the post-learning experience multiple choice questionnaire, with no difference between the intervention and control groups. In the intervention group, time for task completion was significantly less compared to the control group (1-2 min vs. 2-3 min, p = 0.039). Both learning experiences significantly (p < 0.001) enhanced student confidence, with no significant difference between intervention and control groups. 100% of the students using the VRLE enjoyed the experience, and 82.4% were very likely to recommend use of VRLE in medical education. 94.1% of the students felt the VRLE was beneficial over didactic teaching. Conclusion Receiving formal instruction, regardless of format, enhances students' knowledge and confidence of the topic covered. Students who received instruction via the VRLE assembled the postpartum balloon faster than students who received didactic teaching. VR may be beneficial in teaching hands-on procedural skills in obstetrics and gynecology education.

Abstract
BACKGROUND Osteogenesis Imperfecta (OI) is characterised by bone fragility. Among several features, easy bruising and multiple case reports on haemorrhagic events have been reported. This paper describes the diverse manifestations of bleeding and bruising in a large cohort of 328 OI patients. The aim of this study is to provide insight in the diverse aspects and therapeutic considerations of bleedings in OI. METHODS This descriptive cohort study was conducted at the National Expert Center for adults with OI in the Netherlands. Bleeding was assessed by the validated self-bleeding assessment tool (Self-BAT) The tool was distributed among 328 adults with different clinically confirmed types of OI. RESULTS 195 of 328 invited patients (completion rate 60%) with OI type 1 (n = 144), OI type 3 (n = 17) and OI type 4 (n = 34), aged between 18 and 82 years, completed the tool. Self-BAT scores were above the normal range in 42% of all patients. For males Self-BAT scores were increased in 37% with a mean score of 3.7, ranged between 0 and 18. For females the Self-BAT scores were increased in 44% with a mean of 5.4 and a range of 0-24. No statistical differences in OI subtypes were found. CONCLUSIONS Bleeding tendency appears to be a relevant complication in OI patients as this study confirms the presumption of bleeding tendency. There are specific recommendations to clinicians who treat OI patients to consider an assessment of bleeding tendency and use potential interventions to reduce haemorrhagic complications and improve quality of life.

Abstract
Women or people with a uterus are vulnerable to both normal and abnormal bleeding. During the reproductive years, the uterus is prepared physiologically to accept an embryo and support its growth and development during pregnancy, or in the absence of implantation of an embryo, recycle through the process of menstruation and accept an embryo a month or so later. If fertilization takes place and an embryo or embryos implant in the uterus, the fetal trophoblast, or outer cell layer of the embryo, invades and dilates the maternal spiral arteries and forms the placenta. No matter when in gestation a pregnancy ends, at the conclusion of pregnancy, the placenta should separate from the wall of the uterus and be expelled. Abnormal bleeding occurs during pregnancy or after delivery when the normal uteroplacental interface has not been established or is interrupted; during miscarriage; during ectopic pregnancy; during premature separation of the placenta; or during postpartum hemorrhage. Heavy menstrual bleeding, a subset of abnormal menstrual bleeding, can be quantitatively defined as >80 mL of blood loss per cycle. Unlike postpartum hemorrhage, heavy menstrual bleeding is significantly associated with an underlying bleeding disorder. While there is other reproductive tract bleeding in women, notably bleeding at the time of ovulation or with a life-threatening ruptured ectopic pregnancy, the unique bleeding that women experience is predominantly uterine in origin. Many of the unique aspects of uterine hemostasis, however, remain unknown.

Abstract
OBJECTIVES To compare pregnancy complications in pregnancies with and without pre-gestational diabetes mellitus (DM) managed in a multidisciplinary high-risk diabetes antenatal clinic. METHODS This screening cohort study was undertaken at a large maternity unit in the United Kingdom between January 2010 and December 2022. We included singleton pregnancies that booked at our unit at 11-13 weeks' gestation. Univariate and multivariate logistic regression analysis was carried out to determine risks of complications in pregnancies with type 1 and type 2 DM after adjusting for maternal and pregnancy characteristics. Effect sizes were expressed as absolute risks (AR) and odds ratio (OR) (95 % confidence intervals [CI]). RESULTS The study population included 53,649 singleton pregnancies, including 509 (1.0 %) with pre-existing DM and 49,122 (99.0 %) without diabetes. Multivariate logistic regression analysis demonstrated that there was a significant contribution from pre-existing DM in prediction of adverse outcomes, including antenatal complications such as fetal defects, stillbirth, preterm delivery, polyhydramnios, preeclampsia and delivery of large for gestational age (LGA) neonates; intrapartum complications such as caesarean delivery (CS) and post-partum haemorrhage; and neonatal complications including admission to neonatal intensive care unit, hypoglycaemia, jaundice and hypoxic ischaemic encephalopathy (HIE). In particular, there was a 5-fold increased risk of stillbirth and HIE. CONCLUSIONS The maternal and neonatal complications in pregnancies with pre-existing DM are significantly increased compared to those without DM despite a decade of intensive multidisciplinary antenatal care. Further research is required to investigate strategies and interventions to prevent morbidity and mortality in pregnancies with pre-gestational DM.

Jin XQ, Shen YH, Fu F, Yu J, Xiao F, Huang XD. Oxytocin infusion for maintenance of uterine tone under prophylactic phenylephrine infusion for prevention of post-spinal hypotension in cesarean delivery: a prospective randomised double-blinded dose-finding study. BMC Pregnancy Childbirth 2023; 23:840. [PMID: 38057742 DOI: 10.1186/s12884-023-06165-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 11/29/2023] [Indexed: 12/08/2023] Open
Abstract
BACKGROUND Prior studies have shown that, when administered as an intravenous bolus to prevent uterine atony, prophylactic phenylephrine infusion increased the dose requirement of oxytocin and second-line uterotonics. For the prevention of uterine atony, oxytocin should be delivered by continuous infusion. Here, we aimed to determine the ED50 and ED90 parameters (the effective doses for 50 and 90% patients without uterine atony) of oxytocin for co-infusion with prophylactic phenylephrine during cesarean delivery. METHODS In this prospective randomized double-blinded dose-finding study, one hundred patients were divided into four groups to receive 2.5, 5.0, 7.5, or 10 IU/h oxytocin infusion, after the umbilical cord was clamped during the study period. The uterine tone was evaluated and defined as either adequate or inadequate. Probit regression analysis was applied to calculate the ED50 and ED90 of oxytocin infusion. Uterine tone, the percentage of patients who needed additional oxytocin bolus, second-line uterotonics, side effects, estimated blood loss, and neonatal outcomes were monitored. RESULTS The estimated ED50 and ED90 values of the oxytocin infusion doses for the prevention of uterine atony were 1.9 IU/h (95% CI -4.6-3.8) IU/h and 9.3 IU/h (95% CI 7.3-16.2) IU/h, respectively. Across groups, there was a significant linear trend between the infusion dose and the percentage of patients who required additional oxytocin (p-value = 0.002). No differences were observed in the incidence of side effects and neonatal outcomes. CONCLUSION Under the conditions of this study, the ED90 of oxytocin infusion for the prevention of uterine atony was 9.3 IU/h, which is higher than the current recommendation. This finding is helpful for clinical practice, because of the routine use of phenylephrine in cesarean delivery. Further studies are needed to determine the appropriate initial bolus of oxytocin after neonatal delivery. TRIAL REGISTRATION The study was registered on the Chinese Clinical Trial Register (register no. ChiCTR2200059556 ).

Sociodemographic factors associated with immediate puerperal control: A cross-sectional study based on the Peruvian demographic and health survey, 2019. Eur J Obstet Gynecol Reprod Biol X 2023; 20:100253. [PMID: 37942026 PMCID: PMC10628648 DOI: 10.1016/j.eurox.2023.100253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 09/14/2023] [Accepted: 10/11/2023] [Indexed: 11/10/2023] Open
Abstract
Introduction Peru is the fifth country in Latin America with the highest maternal mortality. In Peru, immediate puerperal control (IPC) was established in 2013 as a measure to improve postnatal control, with a view in reducing maternal mortality. This study aimed to evaluate the frequency and sociodemographic factors associated with compliance with IPC in Peru, 2019. Methods We conducted an analytical cross-sectional study based on the Demographic and Family Health Survey (ENDES, for its acronym in Spanish) of Peru, 2019. The dependent variable was compliance with IPC (control in the first 2 h) in women aged 15-49 years who had delivered within the last five years preceding the survey. To evaluate the associated factors, Poisson family generalized linear models were used to calculate crude (cPR) and adjusted (aPR) prevalence ratios, with their respective 95% confidence intervals (95%CI). Results Data from 11,854 women were analyzed. The frequency of IPC was 59.6% (95%CI: 58.3-60.9). We found a lower proportion of IPC in urban areas (58.8%) and in the highlands (57%) and jungle (57.2%) of Peru. Residing in rural areas (aPR:1.13; 95%CI:1.08-1.19), having undergone appropriate antenatal care (ANC) (aPR:1.05; 95%CI:1.01-1.10) and having delivered a low-birth-weight newborn (aPR:1.20; 95%CI:1.12-1.29) were associated with a higher frequency of IPC, while living in the highlands (aPR:0.86; 95%CI:0.80-0.92) or jungle (aPR:0.86; 95%CI:0.80-0.92) was associated with a lower frequency of IPC. Conclusions Approximately four out of ten women did not have IPC. There was a lower proportion of IPC in urban areas and in the highland and jungle regions.

Abstract
OBJECTIVE To compare guidelines from eight high-income countries on prevention and management of postpartum haemorrhage (PPH), with a particular focus on severe PPH. DESIGN Comparative study. SETTING High-resource countries. POPULATION Women with PPH. METHODS Systematic comparison of guidance on PPH from eight high-income countries. MAIN OUTCOME MEASURES Definition of PPH, prophylactic management, measurement of blood loss, initial PPH-management, second-line uterotonics, non-pharmacological management, resuscitation/transfusion management, organisation of care, quality/methodological rigour. CONCLUSIONS Our study highlights areas where strong evidence is lacking. There is need for a universal definition of (severe) PPH. Consensus is required on how and when to quantify blood loss to identify PPH promptly. Future research may focus on timing and sequence of second-line uterotonics and non-pharmacological interventions and how these impact maternal outcome. Until more data are available, different transfusion strategies will be applied. The use of clear transfusion-protocols are nonetheless recommended to reduce delays in initiation. There is a need for a collaborative effort to develop standardised, evidence-based PPH guidelines. RESULTS Definitions of (severe) PPH varied as to the applied cut-off of blood loss and incorporation of clinical parameters. Dose and mode of administration of prophylactic uterotonics and methods of blood loss measurement were heterogeneous. Recommendations on second-line uterotonics differed as to type and dose. Obstetric management diverged particularly regarding procedures for uterine atony. Recommendations on transfusion approaches varied with different thresholds for blood transfusion and supplementation of haemostatic agents. Quality of guidelines varied considerably.

Abstract
AIM Cryoprecipitate (CRYO) is a concentrated preparation of coagulation factors formulated from fresh frozen plasma (FFP), which can replenish coagulation factors rapidly. Preeclampsia (PE) is frequently associated with postpartum hemorrhage (PPH), and the rapid replenishment of coagulation factors is vital in the management. We conducted a retrospective cohort study to determine the efficacy of administering CRYO irrespective of fibrinogen levels in patients with PE who experienced severe PPH. METHODS Patients with PPH accompanied by PE and those who required red blood cell (RBC) transfusion were included. Cases were divided into two groups: those treated with CRYO (N = 16) and those not treated with CRYO (N = 10). The total transfusion volume, blood loss before and after transfusion initiation, duration of hospitalization, presence of pulmonary edema, and performance of either interventional radiology or hysterectomy were compared. RESULTS The median fibrinogen levels before transfusion were 2.24 and 2.34 g/L in the CRYO group and the not using group, respectively. Although blood loss before transfusion was comparable between the two groups, blood loss after transfusion was significantly less in the CRYO group (median: 520 vs. 2352 mL, p = 0.015), as well as the total blood loss (median: 2285 vs. 3825 mL, p = 0.005) and total transfusion volume (median: RBC 6 vs. 16 U, p = 0.01, FFP 10 vs. 20 U, p = 0.017). CONCLUSION Prompt replenishment of coagulation factors using CRYO to patients with PE who experience severe PPH could decrease further bleeding.

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
OBJECTIVE This study aimed to measure the effect of a coleadership model on team performance compared with singular leadership model in simulated maternity emergencies. METHODS A randomized, counterbalanced, crossover trial was performed at 2 tertiary maternity hospitals. Teams of obstetric physicians and nurse/midwives responded to 2 simulated maternity emergencies in either a singular or coleadership model. The primary outcome measure was teamwork rated with the Auckland Team Behavior tool. Secondary outcome measures included clinical performance (completion of critical tasks, time to critical intervention, documentation), self-rated teamwork (TEAM tool) and workload. Participants also answered a survey assessing their views on the coleadership model. Paired t tests and mixed-effects linear regression considering team as a random effect were used to estimate the unadjusted and adjusted associations between leadership model and the outcomes of interest. RESULTS There was no difference between leadership models for the primary outcome of teamwork (5.3 vs. 5.3, P = 0.91). Clinical outcome measures and self-rated teamwork scores were also similar. Team leaders reported higher workload than other team members, but these were not different between the leadership models. Participants viewed coleadership positively despite no measured objective evidence of benefit. CONCLUSIONS A coleadership model did not lead to a difference in team performance within simulated maternity emergencies. Despite this, participants viewed coleadership positively.

Abstract
Postpartum hemorrhage (PPH) remains a significant obstetric emergency worldwide and a leading cause of maternal death. However, it is commonly underreported, which can represent a major concern for maternal morbidity and mortality. This retrospective case series study analyzed patients with red blood cell transfusion (RBCt) in the postpartum period over a four-year interval at a specific center. A total of 18,674 patients delivered between January 2018 and December 2021. Patients with postpartum RBCt were classified into two groups: those with identified PPH (i-PPH) and those without (non-i-PPH). Clinical variables, delivery details, blood loss data, and treatment information were collected. Statistical analysis involved a comparison of variables between the i-PPH and non-i-PPH groups. Univariate and multivariate analyses were performed, aiming to identify significant associations between the clinical variables and a lack of PPH identification. The incidence of RBCt was 1.26% (236 cases). Patients receiving RBCt had higher rates of cesarean delivery, twin pregnancy, labor induction, and previous cesarean section. Among patients with postpartum RBCt, 34.3% lacked an identified PPH. The rarity of postpartum RBCt contrasts with the increasing rates of PPH, highlighting the importance of diagnosing PPH and postpartum anemia. A strategy of systematic quantification of blood loss during delivery could help detect PPH and anemia before adverse consequences occur.

Abstract
BACKGROUND Because there is no consensus on the method of assessing postpartum blood loss, the comparability and relevance of the postpartum hemorrhage-related literature are questionable. Quantitative blood loss assessment using a volumetric technique with a graduated collector bag has been proposed to overcome limitations of intervention-based outcomes but remains partly subjective and potentially biased by amniotic fluid or missed out-of-bag losses. Calculated blood loss based on laboratory parameters has been studied and used as an objective method expected to reflect total blood loss. However, few studies have compared quantitative with calculated blood loss. OBJECTIVE This study aimed to compare the distribution of postpartum blood loss after vaginal delivery assessed by 2 methods-quantitative and calculated blood loss-and the incidence of abnormal blood loss with each method. STUDY DESIGN Data were obtained from the merged database of 3 multicenter, randomized controlled trials, all testing different interventions to prevent postpartum blood loss in individuals with a singleton live fetus at ≥35 weeks of gestation, born vaginally. All 3 trials measured blood loss volume by using a graduated collector bag. Hematocrit was measured in the eighth or ninth month of gestation and on day 2 postpartum. The 2 primary outcomes were: quantitative blood loss, defined by the total volume of blood loss measured in a graduated collector bag, and calculated blood loss, mathematically defined from the peripartum hematocrit change (estimated blood volume × [(antepartum hematocrit-postpartum hematocrit)/antepartum hematocrit], where estimated blood volume [mL]=booking weight [kg] × 85). We modeled the association between positive quantitative blood loss and positive calculated blood loss with polynomial regression and calculated the Spearman correlation coefficient. RESULTS Among the 8341 individuals included in this analysis, the median quantitative blood loss (100 mL; interquartile range, 50-275) was significantly lower than the median calculated blood loss (260 mL; interquartile range, 0-630) (P<.05). The incidence of abnormal blood loss was lower with quantitative blood loss than calculated blood loss for all 3 thresholds: for ≥500 mL, it was 9.6% (799/8341) and 32.3% (2691/8341), respectively; for ≥1000 mL, 2.1% (176/8341) and 11.5% (959/8341); and for ≥2000 mL, 0.1% (10/8341) and 1.4% (117/8341) (P<.05). Quantitative blood loss and calculated blood loss were significantly but moderately correlated (Spearman coefficient=0.44; P<.05). The association between them was not linear, and their difference tended to increase with blood loss. Negative calculated blood loss values occurred in 23% (1958/8341) of individuals; among them, >99% (1939/1958) had quantitative blood loss ≤500 mL. CONCLUSION Quantitative and calculated blood loss were significantly but moderately correlated after vaginal delivery. However, clinicians should be aware that quantitative blood loss is lower than calculated blood loss, with a difference that tended to rise as blood loss increased.

Abstract
BACKGROUND Postpartum hemorrhage is a major component of perinatal morbidity and mortality that affects young women worldwide and is still often unpredictable. Reducing the incidence of postpartum hemorrhage is a major health issue and identifying women at risk for postpartum hemorrhage is a key element in preventing this complication. OBJECTIVE This study aimed to estimate postpartum hemorrhage prevalence after vaginal delivery and to identify postpartum hemorrhage risk factors. STUDY DESIGN Unselected pregnant women ≥16 years of age admitted to 1 of 6 maternity wards in Brittany (France) for vaginal birth after 15 weeks of gestation were recruited in this prospective, multicenter cohort study between June 1, 2015, and January 31, 2019. Postpartum hemorrhage was defined as blood loss ≥500 mL in the 24 hours following delivery. Independent risk factors for postpartum hemorrhage were determined using logistic regression. Missing data were imputed using the Multivariate Imputation by Chained Equations method. RESULTS Among 16,382 included women, the postpartum hemorrhage prevalence was 5.37%. A first-degree family history of postpartum hemorrhage (adjusted odds ratio, 1.63; 95% confidence interval, 1.24-2.14) and a personal transfusion history (adjusted odds ratio, 1.90; 95% confidence interval, 1.23-2.92) were significantly associated with postpartum hemorrhage. The use of oxytocin during labor was also a risk factor for postpartum hemorrhage (adjusted odds ratio, 1.24; 95% confidence interval, 1.06-1.44). Inversely, smoking during pregnancy and intrauterine growth restriction were associated with a reduced risk for postpartum hemorrhage (adjusted odds ratio, 0.76; 95% confidence interval, 0.63-0.91, and 0.34; 95% confidence interval, 0.13-0.87, respectively). CONCLUSION In addition to classical risk factors, this study identified a family history of postpartum hemorrhage and personal transfusion history as new characteristics associated with postpartum hemorrhage after vaginal delivery. The association of postpartum hemorrhage with a family history of postpartum hemorrhage suggests a hereditary hemorrhagic phenotype and calls for genetic studies. Identifying women at risk for postpartum hemorrhage is a key element of being prepared for this complication.

Does antenatal cholecalciferol supplementation affect the mode or timing of delivery? Post hoc analyses of the MAVIDOS randomized controlled trial. J Public Health (Oxf) 2023; 45:738-747.

Abstract
BACKGROUND Observational studies relating maternal 25-hydroxyvitamin D status to timing and mode of delivery have reported inconsistent results. We assessed the effect of antenatal cholecalciferol supplementation on the incidence of preterm birth, delivery mode and post-partum haemorrhage (PPH). METHODS MAVIDOS was a randomized, double-blind, placebo-controlled trial of 1000 IU/day cholecalciferol from 14 weeks' gestation until delivery. Gestational age, mode of delivery [categorized as spontaneous vaginal delivery (SVD), instrumental (including forceps and vacuum extraction) or Caesarean section] and PPH (>500 ml estimated blood loss) were determined from medical records. RESULTS A total of 965 women participated in the study until delivery. Gestation at birth and incidence of preterm birth (cholecalciferol 5.7%, placebo 4.5%, P = 0.43) were similar between the two treatment groups. SVD (versus instrumental or Caesarean delivery) was more likely in women randomized to cholecalciferol [Relative Risk (RR) 1.13, 95% confidence interval (CI) 1.02,1.25] due to lower instrumental (RR 0.68, 95%CI 0.51,0.91) but similar risk of Caesarean delivery (RR 0.94, 95%CI 0.74,1.19). PPH was less common in women randomized to cholecalciferol [32.1% compared with placebo (38.1%, P = 0.054) overall], but similar when stratified by delivery mode. CONCLUSIONS Antenatal cholecalciferol supplementation did not alter timing of birth or prevalence of preterm birth but demonstrated a possible effect on the likelihood of SVD.

Abstract
OBJECTIVE This study compares the effectiveness of administering sublingual misoprostol combined with oxytocin to that of IV tranexamic acid combined with oxytocin to reduce intra and post-operative blood loss in high-risk women for postpartum haemorrhage (PPH) following cesarean section (CS). METHODS About 315 high-risk pregnant women undergoing CS participated in this trial. They were randomly assigned into three groups; tranexamic group, misoprostol group, and control group, according to the medication given in the operative theatre. All patients received oxytocin intraoperatively. They were assessed regarding intraoperative blood loss, the incidence of PPH, and the reduction in haemoglobin and hematocrit values. RESULTS Both tranexamic and misoprostol groups had similar results in reducing intra and post-operative blood loss. However, the reduction in haemoglobin and hematocrit were significantly lower in tranexamic and misoprostol groups compared to the control group (-0.78 ± 0.57 vs. -0.83 ± 0.52 vs. -1.32 ± 0.57 gm/dl, P < 0.001 and - 3.05 ± 1.28 vs. -3.06 ± 1.13 vs. -4.94 ± 1.82%, P < 0.001 respectively). In addition, the estimated blood loss was significantly lower in the tranexamic and misoprostol groups compared to the control group (641.6 ± 271.9 vs. 617.9 ± 207.4 vs. 1002.4 ± 340.7 ml, P < 0.001). CONCLUSION Both tranexamic acid and misoprostol are equally capable of reducing blood loss, but the results were significantly better compared to using oxytocin alone in high-risk patients.

Abstract
OBJECTIVES To assess the risk of complications in women undergoing termination of pregnancy (TOP) for fetal defects and to examine the impact of gestational age on the complication rate. METHODS This was a retrospective study of women with a singleton pregnancy undergoing TOP at the University Hospital of Tübingen, Germany, between 2018 and 2021. TOP was performed by experienced operators according to the national protocol; dilatation and curettage (D&C) or evacuation (D&E) was used in the first and early second trimesters and induction was used later in pregnancy. The following were considered to be significant procedure-related complications: blood loss of more than 500 mL, uterine perforation, need for blood transfusion, allergic reaction, creation of a false passage (via falsa), systemic infection, readmission to hospital, any unplanned surgical procedure, such as repeat D&C/D&E or hysterectomy, and maternal death. RESULTS The search of the hospital database identified 416 pregnancies that met the study criteria. Median maternal and gestational age at termination were 34.1 years and 17.4 weeks, respectively. In the first, second and third trimesters, respectively, 84 (20.2%), 278 (66.8%) and 54 (13.0%) pregnancies were terminated, for which D&C or D&E was used in 80 (95.2%), 21 (7.6%) and 0 (0.0%) cases. Seventy-seven (18.5%) women had at least one previous Cesarean section and 169 (40.6%) had at least one previous spontaneous delivery. Overall, 95 (22.8%) women had complications during or after TOP. A significantly higher complication rate was noted for terminations performed later in pregnancy. The median gestational age at termination was 16.6 weeks in women who did not experience complications and 20.7 weeks in those with complications (P < 0.001). The respective complication rates in the first, second and third trimesters were 6.0%, 27.0% and 27.8%. CONCLUSION In women undergoing TOP for fetal defects, the risk of complications increases with advancing gestational age. © 2023 The Authors.

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 < 0.01), major previa (OR 3.15; 95% CI 1.19-8.32, p < 0.01), and placenta accreta spectrum (PAS) (OR 92.7; 95% CI 18.39-467.22, p < 0.01) were more frequent in the RPOC group. Multivariate analysis revealed that prior CS (OR 10.70; 95% CI 3.47-33.00, p < 0.01,) and PAS (OR 140.32; 95% CI 23.84-825.79, p < 0.01) were risk factors for RPOC. In pregnant women who have placenta previa with RPOC or without RPOC, the ratio of severe PPH were 58.3% and 4.5%, respectively (p < 0.01). Furthermore, the occurrence of prior CS (OR 9.23; 95% CI 4.02-21.20, p < 0.01), major previa (OR 11.35; 95% CI 3.35-38.38, p < 0.01), placenta at the anterior wall (OR 3.44; 95% CI 1.40-8.44, p = 0.01), PAS (OR 16.47; 95% CI 4.66-58.26, p < 0.01), and RPOC (OR 29.70; 95% CI 11.23-78.55, p < 0.01) was more in pregnant women with severe PPH. In the multivariate analysis for severe PPH, prior CS (OR 4.71; 95% CI 1.29-17.13, p = 0.02), major previa (OR 7.50; 95% CI 1.98-28.43, p < 0.01), and RPOC (OR 13.26; 95% CI 3.61-48.63, p < 0.01) were identified as risk factors. CONCLUSIONS Prior CS and PAS were identified as risk factors for RPOC in placenta previa and RPOC is closely associated with severe PPH. Therefore, a new strategy for RPOC in placenta previa is needed.

Comparative study between oxytocin and combination of tranexamic acid and ethamsylate in reducing intra-operative bleeding during emergency and elective cesarean section after 38 weeks of normal pregnancy. BMC Pregnancy Childbirth 2023; 23:433.

Abstract
OBJECTIVE Cesarean Section (CS) is associated with an increased risk of hemorrhage. Many drugs are used to decrease this risk. We aim to compare the combination of ethamsylate and tranexamic acid, oxytocin, and placebo in women undergoing CS. METHODS We conducted a double-blinded, randomized, placebo-controlled trial between October and December 2020 in four university hospitals in Egypt. The study included all pregnant women in labor without any complications who accepted to participate in the study between October and December 2020. The participants were divided into three groups. The subjects were randomly allocated to receive either oxytocin (30 IU in 500 ml normal saline during cesarean section), combined one gram of tranexamic acid with 250 mg of ethamsylate once before skin incision, or distilled water. Our main outcome was the amount of blood loss during the operation. The secondary outcomes were the need for blood transfusion, hemoglobin and hematocrit changes, hospital stay, operative complications, and the need for a hysterectomy. The one-way ANCOVA test was used to compare the quantitative variables between the three groups while the Chi-square test was used to compare the qualitative variables. Post hoc analysis then was performed to compare the difference between every two groups regarding the quantitative variables. RESULTS Our study included 300 patients who were divided equally into three groups. Tranexamic acid with ethamsylate showed the least intra-operative blood loss (605.34 ± 158.8 ml) compared to oxytocin (625.26 ± 144.06) and placebo (669.73 ± 170.69), P = 0.015. In post hoc analysis, only tranexamic acid with ethamsylate was effective in decreasing the blood loss compared to placebo (P = 0.013); however, oxytocin did not reduce blood loss compared to saline (P = 0.211) nor to tranexamic acid with ethamsylate (P = 1). Other outcomes and CS complications showed no significant difference between the three groups except for post-operative thrombosis which was significantly higher in the tranexamic and ethamsylate group, P < 0.00001 and the need for a hysterectomy which was significantly increased in the placebo group, P = 0.017. CONCLUSION The combination of tranexamic acid and ethamsylate was significantly associated with the least amount of blood loss. However, in pairwise comparisons, only tranexamic acid with ethamsylate was significantly better than saline but not with oxytocin. Both oxytocin and tranexamic acid with ethamsylate were equally effective in reducing intra-operative blood loss and the risk of hysterectomy; however, tranexamic acid with ethamsylate increased the risk of thrombotic events. Further research with a larger number of participants is needed. TRIAL REGISTRATION The study was registered on Pan African Clinical Trials Registry with the following number: PACTR202009736186159 and was approved on 04/09/2020.

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 < 0.00001, cohort studies: P < 0.00001), 2-h postpartum (RCT: P = 0.02, cohort studies: P < 0.00001) and total blood loss (RCT: P < 0.00001, cohort studies: P = 0.0002), and reduced the decline in hemoglobin (RCT: P < 0.00001, cohort studies: P = 0.0001), but did not significantly affect blood loss at 6-h postpartum (P = 0.05). CONCLUSION Prophylactic intravenous TXA before cesarean section is helpful in preventing perioperative bleeding in women.

Abstract
PURPOSE OF REVIEW Excessive bleeding during and following childbirth remains one of the leading causes of maternal mortality. RECENT FINDINGS Current guidelines differ in definitions and recommendations on managing transfusion and hemostasis in massive postpartum hemorrhage (PPH). Insights gained from trauma-induced coagulopathy are not directly transferable to the obstetric population due to gestational alterations and a differing pathophysiology. SUMMARY Factor deficiency is uncommon at the beginning of most etiologies of PPH but will eventually develop from consumption and depletion in the absence of bleeding control. The sensitivity of point-of-care tests for fibrinolysis is too low and may delay treatment, therefore tranexamic acid should be started early at diagnosis even without signs for hyperfibrinolysis. Transfusion management may be initiated empirically, but is best to be guided by laboratory and viscoelastic assay results as soon as possible. Hypofibrinogenemia is well detected by point-of-care tests, thus substitution may be tailored to individual needs, while reliable thresholds for fresh frozen plasma (FFP) and specific components are yet to be defined. In case of factor deficiency, prothrombin complex concentrate or lyophilized plasma allow for a more rapid restoration of coagulation than FFP. If bleeding and hemostasis are under control, a timely anticoagulation may be necessary.

Abstract
BACKGROUND Clinical practice guidelines for postpartum hemorrhage (PPH) are available worldwide, but no review has assessed the quality of these guidelines. Poor-quality guidelines for PPH may lead clinicians to follow incorrect approaches. OBJECTIVES High-quality guidelines for PPH are important in guiding the clinical diagnosis and treatment of PPH and decreasing maternal mortality. The aim of this study was to assess the quality of clinical guidelines for PPH. METHODS We collected studies from different countries through a literature search including PubMed (MEDLINE), Web of Science, the Cochrane library, websites of health institutions from multiple countries, and search sites, according to the criterion of clinical guidelines for treatment of PPH published between inception and October 2022. Four independent reviewers assessed the eligible guidelines by using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. Agreement among reviewers of the guidelines was measured with the intra-class correlation coefficient (ICC). The number of recommendations, strength of recommendations, and level of evidence were determined. RESULTS Seven sets of PPH guidelines published from 2007 to 2022 were identified. An overall high agreement among reviewers in each domain was observed (ICC 0.74 to 0.95). The median scores and ranges for each AGREE II domain were as follows: (i) scope and purpose (median = 86.51%, range: 61.11%-94.44%); (ii) stakeholder involvement (median = 73.02%, range: 52.78%-90.28%); (iii) rigor of development (median = 76.49%, range: 66.15%-97.92%); (iv) clarity and presentation (median = 88.49%, range: 68.06%-100.00%); (v) applicability (median = 73.36%, range: 53.13%-93.75%); and (vi) editorial independence (median = 84.52%, range: 60.42%-95.83%). Three sets of PPH guidelines scored high in all domains and were classified as recommended for clinical practice. The other guidelines were classified as recommended with modifications. CONCLUSION The methodological and reporting quality of the guidelines for PPH included in this review was generally good, but the strength of the recommendations and the quality of the evidence varied, thus potentially leading to confusion among clinicians applying the guidelines. An urgent need exists for rigorous studies to close important evidence gaps to support the development of guidelines for PPH.

Front Med (Lausanne) 2023; 10:1139430. [PMID: 37144027 PMCID: PMC10151667 DOI: 10.3389/fmed.2023.1139430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2023] [Accepted: 03/28/2023] [Indexed: 05/06/2023] Open
Abstract
Background Postpartum hemorrhage (PPH) is the most common cause of maternal morbidity and mortality worldwide. A reliable risk assessment tool for PPH could optimize available interventions to reduce adverse maternal outcomes. Objective The objective of this study was to explore a nomogram predicting the risk of postpartum hemorrhage after cesarean delivery for twin pregnancies. Methods This single-center retrospective cohort study conducted twin pregnancies who underwent cesarean delivery between January 2014 and July 2021. Propensity score matching at baseline was used to match PPH (blood loss ≥1000 mL) and non-PPH group (blood loss <1000 mL). A nomogram was developed to predict the risk of PPH in cesarean delivery for twin pregnancies. The receiver operating characteristic curve (ROC), calibration plot, and decision curve analysis (DCA) were, respectively, used to evaluate the discrimination, calibration, and clinical utility of the prediction models. Results After propensity score matching, 186 twin pregnancies in the PPH group were matched with 186 controls in the non-PPH group. Seven independent prognostic variables, including antepartum albumin, assisted reproductive technology, hypertensive disorders of pregnancy, placenta previa, placenta accrete spectrum, intrapartum cesarean delivered, and estimated weights of twins, were used to build the nomogram. Based on the performance of the model, it appears that a good calibration (Hosmer-Lemeshow χ2 = 4.84, P > 0.05), an excellent predictive ability (area under the curve: 0.778, 95% CI: 0.732-0.825), and a good positive net benefit in the predictive model have been achieved. Conclusion The nomogram was first generated to predict PPH in cesarean delivery for twin pregnancies, which could help clinicians to provide a reference for the preoperative surgical plan, choose optimal treatments, optimize healthcare resources, and thereby reduce the associated adverse maternal outcomes.

Abstract
BACKGROUND We evaluated the safety, efficacy, and acceptability of a new device designed to facilitate uterine compression in women with postpartum haemorrhage (PPH). METHODS A prospective, phase two clinical device trial with concurrent qualitative study, conducted in a UK consultant obstetric unit. The device was used in addition to standard care in women unresponsive to initial oxytocin therapy. The primary effectiveness outcome was additional blood loss of over 1000mls, whilst safety was assessed through adverse events. Interviews assessed device feasibility and acceptability, and were analysed using framework analysis. RESULTS We recruited 57 women with clinical PPH after vaginal birth; 67% were primiparous and 47% had undergone operative birth. All but two (96%) had atony as a cause of the haemorrhage; in addition, 30% also had bleeding from lacerations and 11% had retained tissue. After device use, only one woman had additional blood loss over 1000mls, although 3 women (7%) needed a Bakri balloon and 14% received a blood transfusion. All but one clinician felt that the device was easy to use. Clinicians stated that the device assisted management in 85% of cases. All 56 women who responded stated that if they bled in a future birth they would want the device to be used again. There were no serious adverse events related to the device. However, 3 events were judged as 'possibly' being caused by the device - 2 minor vaginal grazes and one postnatal episiotomy infection and breakdown. Lax vaginal tissue complicated the use of the device in three women. In 47 interviews, participants, birth partners, clinician users and attending midwives viewed the device positively. Clinicians found it useful as a way of stopping blood loss and as an aid to diagnose the source of bleeding. CONCLUSIONS The PPH Butterfly may provide a rapid, acceptable and effective treatment for postpartum haemorrhage.

Abstract
Hypofibrinogenemia is often associated with excessive bleeding and requires immediate treatment. The qLabs FIB® is a handheld and easy-to-use point-of-care (POC) device designed for the rapid measurement of functional fibrinogen concentration from a single drop of citrated whole blood. The aim of this study was to evaluate the analytical performances of the qLabs FIB system. Fibrinogen concentrations from 110 citrated whole blood specimen were measured by both the qLabs FIB and the Clauss laboratory reference methods (STA®-Liquid Fib assay on STA-R® Max from Stago). A three-laboratories comparison study was conducted to assess reproducibility and repeatability of the qLabs FIB using plasma quality control material. In addition, single-site assays were conducted to assess the repeatability from citrated whole blood specimen covering the qLabs FIB reportable range. A very strong correlation between the qLabs FIB and the Clauss laboratory reference method was observed (r = 0.95). Using a clinical cut-off value of 2.0 g/L, the area under the receiver operating characteristic curve (ROC) of citrated whole blood was 0.99 and sensibility and specificity were 100 % and 93.5 %, respectively. Percent CVs for reproducibility and repeatability assessed from quality control material, were both <5 %. Repeatability assessed from citrated whole blood specimen showed a CV of 2.6 to 6.5 %. In conclusion, the qLabs FIB system enables a rapid and reliable measurement of functional fibrinogen levels from citrated whole blood and exhibits a strong prediction power at the 2 g/L clinical cut-off when compared to the Clauss laboratory reference. Further clinical studies should demonstrate its ability to quickly confirm the diagnosis of acquired hypofibrinogenemia and help identify patients who may benefit from targeted hemostatic treatment.

Abstract
Translating evidence-based guidelines into clinical practice is a complex challenge. This observational study aimed to assess the adherence to the Italian national guidelines on postpartum haemorrhage (PPH) and describe the clinical management of haemorrhagic events in a selection of maternity units (MUs) in six Italian regions, between January 2019 and October 2020. A twofold study design was adopted: (i) a before-after observational study was used to assess the adherence to national clinical and organisational key recommendations on PPH management, and (ii) a cross-sectional study enrolling prospectively 1100 women with PPH ≥ 1000 mL was used to verify the results of the before-after study. The post-test detected an improved adherence to 16/17 key recommendations of the guidelines, with clinical governance and communication with family members emerging as critical areas. Overall, PPH management emerged as appropriate except for three recommended procedures that emphasise different results between the practices adopted and the difference between what is considered acquired and what is actually practised in daily care. The methodology adopted by the MOVIE project and the adopted training materials and tools have proved effective in improving adherence to the recommended procedures for appropriate PPH management and could be adopted in similar care settings in order to move evidence into practice.

Abstract
BACKGROUND Secondary postpartum haemorrhage (PPH) is a condition which affects 0.2-3.0% of women. Despite its impact on maternal morbidity, there is a lack of understanding of the cost burden of disease. AIMS To determine the economic cost of secondary PPH in the postpartum period, compared to the costs for women without this diagnosis. MATERIALS AND METHODS Data were prospectively collected on a cohort of 97 women who presented with secondary PPH to the emergency department (ED) between July 2020 and February 2021. A case-control design was then used to compare postpartum cost data from these patients to a group of 97 controls who were matched to maternal demographics, and who did not present with secondary PPH. RESULTS For women with secondary PPH, there were significantly more hospital attendances, and postpartum costs were higher for all cost subcategories across ED, admissions, and outpatient attendances (P < 0.0001), compared to controls. The total cost of postpartum care for 97 patients with secondary PPH was $254 377.62 with an average cost per patient of $2622.45, compared to $26 670.46 for 97 controls with an average cost of $274.95 per patient (P < 0.0001). This demonstrates a 9.5-fold increase in postpartum costs per woman with secondary PPH. CONCLUSIONS Secondary PPH is an under-researched condition which presents a significant cost burden for the health system. Evidence-based guidelines addressing the prevention and management of secondary PPH may assist in minimising this cost burden for both the health service and the patient.

Abstract
Objective The aim was to determine whether follow-up in the intensive care unit (ICU) for the postoperative first eight hours was beneficial for early intervention in postpartum hemorrhage. Material and Methods In our hospital, all patients are admitted to the ICU for the first eight hours after cesarean section. Patients with postpartum hemorrhage after cesarean delivery who received medical and/or surgical treatment between 2016 and 2020 were reviewed in the presented study retrospectively. Results All cases (n=36,396) who underwent cesarean delivery were reviewed. Three hundred and fifty-nine patients with postpartum hemorrhage were identified and included. In the study group the time between cesarean section and diagnosis of postpartum hemorrhage was 10.1±19.1 hours, and the time between cesarean section and re-laparotomy was 9.26±23.1 hours. A total of three maternal deaths occurred after cesarean section in our hospital. In the last five years, the mortality rate in patients delivering by cesarean section was 3.9 per 100,000. The incidence of postpartum hemorrhage in cesarean deliveries at our hospital was calculated to be 1.0%, and the rate of obstetric near-miss events was calculated to be 0.6 per 1000 live births. Conclusion Follow-up of patients in the ICU in the first eight postoperative hours after cesarean section may result in a lower number of re-laparotomies due to postpartum hemorrhage, a shortened interval between cesarean section and re-laparotomy, and a lower maternal mortality rate.

Evaluation of the effect of dinoprostone vaginal ovule for cervical maturation and labor induction in term pregnancies on the duration of the third stage of labor and amount of postpartum bleeding. JOURNAL OF SURGERY AND MEDICINE 2023. [DOI: 10.28982/josam.7738] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 03/11/2023] Open
Abstract
Background/Aim: Postpartum bleeding is a leading preventable cause of maternal death. Prolonged 3rd stage duration of labor and induction agents can increase postpartum bleeding. This study evaluated the effect of using a dinoprostone (PGE2) vaginal insert, a cervical ripening and labor induction agent, on the 3rd stage duration of labor and the amount of postpartum bleeding.
Methods: This prospective cross-sectional study involved 301 patients with vaginal delivery between 01.10.2020 and 30.06.2021. Patients were separated into two groups: PGE2+oxytocin (Group A) and only oxytocin (Group B). They were compared in terms of prepartum and postpartum data, 3rd stage duration of labor, and the amount of blood loss in the first 18 h postpartum.
Results: The median 3rd stage duration of labor was 8 min in Group A and 7 min in Group B (P=0.009). No significant differences were found between the groups in the amount of postpartum blood loss, percentage changes in hemoglobin and hematocrit values, or when patients were analyzed based on 3rd stage duration of labor (≤10 vs. >10 min). Severe postpartum hemorrhage (≥1000 ml) was associated with decreased gravida, increased body mass index, longer oxytocin use, and prolonged 3rd stage duration of labor in all patients. In Group A, severe postpartum hemorrhage was associated with decreased gravida, increased body mass index, and longer duration of PGE2 use.
Conclusion: PGE2 prolonged the 3rd stage duration of labor, but this did not increase postpartum bleeding compared to oxytocin. However, an increase in the duration of PGE2 use was associated with postpartum hemorrhage. Therefore, shortening the duration may be considered in patients with additional risk for postpartum hemorrhage.

Abstract
Postpartum hemorrhage (PPH) is a common cause of significant maternal morbidity and mortality that can be associated with coagulopathy, especially hypofibrinogenemia. There is interest in point-of-care viscoelastic hemostatic assays (POC-VHA) in PPH because prompt knowledge of coagulation status can aid diagnosis, identify cases of severe coagulopathy, and allow ongoing monitoring during rapid bleeding. The incidence of coagulopathy in most cases of PPH is low because of the procoagulant state of pregnancy, including raised fibrinogen levels of around 4 to 6 g/L. A Clauss fibrinogen of >2 g/L or POC-VHA equivalent has been found to be adequate for hemostasis during PPH. POC-VHA has been used successfully to diagnose hypofibrinogenemia (Clauss fibrinogen of ≤2 g/L) and guide fibrinogen treatment which has reduced bleed size and complications of massive transfusion. There are uncertainties about the use of POC-VHA to direct fresh frozen plasma and platelet administration during PPH. Several POC-VHA algorithms have been used successfully incorporated in the management of many thousands of PPHs and clinicians report that they are easy to use, interpret, and aid decision making. Due to the relative cost of POC-VHA and lack of definitive data on improving outcomes, these devices have not been universally adopted during PPH.

Abstract
OBJECTIVE To examine women and their partners' experience of major postpartum haemorrhage (PPH). DESIGN A qualitative interview study. SETTING Two Labour and Delivery Units in Denmark. POPULATION Women who experienced major PPH (≥1 litre within 2 hours after vaginal birth). METHODS Semi-structured interviews were conducted with 15 women and nine partners (nine joint interviews, six individual interviews). Interviews were analysed using thematic analysis. MAIN OUTCOME MEASURES A qualitative description of women and their partners' experiences. RESULTS Three major themes were identified. (1) 'From birth to emergency' included factors that increased concern in women and their partners, such as 'incomprehensible' medical terminology, a tense atmosphere, and alarm call. Transfer to the operating theatre was experienced as the most devastating part of major PPH. (2) 'Feeling safe during an emergency' described factors that supported the women and their partners' management of the situation such as brief explanations from a few healthcare professionals and reassurance that the healthcare professionals were in control of the situation. The pain was experienced as severe, but acceptable. (3) 'Family unity challenged' described how family bonding was supported by positioning the partner at the head of the bed and by keeping the baby on the woman's chest. CONCLUSIONS Several factors such as small gestures from healthcare professionals and appropriate organisation of the PPH can make a difference to the woman and her partner's experience of major PPH. Particularly, efforts that support family bonding are greatly valued by women and their partners.

Abstract
Postpartum haemorrhage remains a significant cause of maternal morbidity and mortality with the commonest reason being uterine atony. For prevention of uterine atony during caesarean delivery, oxytocin is advocated as a first line drug. There is however no published data regarding utility of a weight-based oxytocin infusion. The present study evaluated dose-response relationship for oxytocin infusion when used as weight-based regimen. A total of 55 non-labouring patients without risk factors for uterine atony and scheduled for caesarean delivery under spinal anaesthesia were enrolled. Randomization was done to receive oxytocin infusion in a dose of 0.1, 0.15, 0.2, 0.25 or 0.3 IU kg-1 h-1 (n = 11 each), initiated at the time of cord clamping and continued until the end of surgery. Successful outcome was defined as attaining an adequate uterine response at 4 min of initiation of infusion and maintained till end of surgery. Oxytocin associated hypotension, tachycardia, ST-T changes, nausea/vomiting, flushing and chest pain were also observed. A significant linear trend for adequate intraoperative uterine tone was seen with increasing dose of weight-based oxytocin infusion (P < 0.001). The effective dose in 90% population (ED90) was 0.29 IU kg-1 h-1 (95% CI = 0.25-0.42). Amongst the oxytocin associated side effects, a significant linear trend was seen between increasing dose of oxytocin infusion and hypotension as well as nausea/vomiting (p = 0.016 and 0.023 respectively). Thus, oxytocin infusion during caesarean delivery may be used as per the patient's body weight.

Abstract
Although the maternal mortality rate has decreased and significant improvements have been made in maternal care, maternal death remains one of the substantial problems of our society. The leading causes of maternal death are postpartum hemorrhage, the most important cause of death in developing countries, and preeclampsia and venous thromboembolism, which are more prevalent in developed countries. To treat these conditions, a variety of therapeutic approaches, including pharmacologic agents and surgical techniques, have been adopted. However, a certain number of pregnant women do not respond to any of these options. That is the main reason for developing new therapeutic approaches. Biological medications are isolated from natural sources or produced by biotechnology methods. Heparin is already successfully used in the therapy of deep venous thrombosis and pulmonary embolism. Blood derivatives, used in an autologous or allogenic manner, have proven to be efficacious in achieving hemostasis in postpartum hemorrhage. Mesenchymal stem cells, alpha-1-microglobulin, and antithrombin exhibit promising results in the treatment of preeclampsia in experimental models. However, it is essential to evaluate these novel approaches' efficacy and safety profile throughout clinical trials before they can become a standard part of patient care.

Abstract
OBJECTIVES To determine whether the maternal plasma concentrations of cytokines are higher in pregnant women with postpartum hemorrhage (PPH) compared to pregnant women without PPH. METHODS A retrospective case-control study included 36 women with PPH and 72 matched controls. Cases and controls were matched for gestational age at delivery, labor status, delivery route, parity, and year of sample collection. Maternal plasma samples were collected up to 3 days prior to delivery. Comparison of the plasma concentrations of 29 cytokines was performed by using linear mixed-effects models and included adjustment for covariates and multiple testing. A false discovery rate adjusted p-value <0.1 was used to infer significance. Random forest models with evaluation by leave-one-out and 9-fold cross-validation were used to assess the combined value of the proteins in predicting PPH. RESULTS Concentrations of interleukin (IL)-16, IL-6, IL-12/IL-23p40, monocyte chemotactic protein 1 (MCP-1), and IL-1β were significantly higher in PPH than in the control group. This difference remained significant after adjustment for maternal age, clinical chorioamnionitis, and preeclampsia. Multi-protein random forest proteomics models had moderate cross-validated accuracy for prediction of PPH [area under the ROC curve, 0.69 (0.58-0.81) by leave-one-out cross validation and 0.73 (0.65-0.81) by 9-fold cross-validation], and the inclusion of clinical and demographic information did not increase the prediction performance. CONCLUSIONS Pregnant women with severe PPH had higher median maternal plasma concentrations of IL-16, IL-6, IL-12/IL-23p40, MCP-1, and IL-1β than patients without PPH. These cytokines could serve as biomarkers or their pathways may be therapeutic targets.

Hospital case volume and maternal adverse events following abnormal deliveries: Analysis using a Japanese national in-patient database. Int J Gynaecol Obstet 2023. [PMID: 36808733 DOI: 10.1002/ijgo.14725] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 02/06/2023] [Accepted: 02/11/2023] [Indexed: 02/20/2023]
Abstract
OBJECTIVE To clarify the relationship between the number of deliveries and maternal outcomes in Japan, considering the declining birth rate and the evidence that hospitals with few deliveries have medical safety issues. METHODS Hospitalizations for deliveries were analyzed using the Diagnosis Procedure Combination database from April 2014 to March 2019, after which maternal comorbidities, maternal end-organ injury, medical treatment during hospitalization, and hemorrhage volume during delivery were compared. Hospitals were divided into four groups based on the number of deliveries per month. RESULTS A total of 792 379 women were included in the analysis, among whom 35 152 (4.4%) received blood transfusions, with a median blood loss of 1450 mL during delivery. Regarding complications, pulmonary embolism was significantly more frequent in hospitals with the lowest number of deliveries. CONCLUSION Using a Japanese administrative database, this study suggests an association between hospital case volume and the occurrence of preventable complications, such as pulmonary embolisms.

Abstract
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 <1 h or more than 10 h, placenta previa and previous history of postpartum hemorrhage. Conclusion A postpartum hemorrhage risk calculator has been designed, which due to its improved accuracy after incorporation of data becomes a useful tool that will require a larger study population to improve its performance in clinical practice and more similar studies to validate it.

Abstract
BACKGROUND Adverse late health outcomes after multimodal treatment for pediatric cancer are diverse and of prime interest. Currently available evidence and survivorship care guidelines are largely based on studies addressing side-effects of two dimensional planned radiotherapy. AIMS The Dutch pediatric 3D-planned radiotherapy (3D-RT) study aims to gain insight in the long-term health outcomes among children who had radiotherapy in the 3D era. Here, we describe the study design, data-collection methods, and baseline cohort characteristics. METHODS AND RESULTS The 3D-RT study represents an expansion of the Dutch Childhood Cancer Survivor study (DCCSS) LATER cohort, including pediatric cancer patients diagnosed during 2000-2012, who survived at least 5 years after initial diagnosis and 2 years post external beam radiotherapy. Individual cancer treatment parameters were obtained from medical files. A national infrastructure for uniform collection and archival of digital radiotherapy files (Computed Tomography [CT]-scans, delineations, plan, and dose files) was established. Health outcome information, including subsequent tumors, originated from medical records at the LATER outpatient clinics, and national registry-linkage. With a median follow-up of 10.9 (interquartile range [IQR]: 7.9-14.3) years after childhood cancer diagnosis, 711 eligible survivors were identified. The most common cancer types were Hodgkin lymphoma, medulloblastoma, and nephroblastoma. Most survivors received radiotherapy directed to the head/cranium only, the craniospinal axis, or the abdominopelvic region. CONCLUSION The 3D-RT study will provide knowledge on the risk of adverse late health outcomes and radiation-associated dose-effect relationships. This information is valuable to guide follow-up care of childhood cancer survivors and to refine future treatment protocols.

Abstract
Iron deficiency anemia during pregnancy is a common concern, affecting 38% of women worldwide and up to 50% in developing countries. It is defined differently throughout all 3 trimesters. It has several detrimental effects on pregnancy outcomes for both the mother and the fetus, such as increasing the risk for postpartum depression, preterm delivery, cesarean delivery, preeclampsia, and low birthweight. Management of iron deficiency anemia is done classically via oral iron supplementation. However, recent evidence has shown that intravenous iron is a good alternative to oral iron if patients are unable to tolerate it, not responding, or present with a new diagnosis very late in pregnancy. Management of iron deficiency anemia was demonstrated to be protective against postpartum hemorrhage. Other ways to prevent postpartum hemorrhage include improving prediction tools that can identify those at risk. Several risk assessment kits have been developed to estimate the risk for postpartum hemorrhage among patients and have been proven useful in the prediction of patients at high risk for postpartum hemorrhage despite limitations among low-risk groups. More comprehensive tools are also being explored by determining clinically relevant factors through nomograms, with some proving their efficacy after implementation. Machine learning is also being used to develop more complete tools by including risk factors previously not accounted for. These newer tools, however, still require external validation before being adopted despite promising results under testing conditions.

Abstract
Despite advances in hemorrhage detection and management, postpartum hemorrhage remains the single leading cause of maternal death worldwide. Within the United States, hemorrhage is the leading cause of maternal death on the day of delivery and within the first week after delivery. Blood transfusion after hemorrhage represents a large proportion of severe maternal morbidity during and after delivery. Blood loss during delivery has historically been assessed visually by inspecting soiled pads, linens, and laparotomy sponges. These methods underestimate the volume of blood loss by as much as 40%, becoming increasingly inaccurate as blood loss increases. Young, healthy obstetrical patients compensate for blood loss via peripheral vasoconstriction, maintaining heart rate and blood pressure in a normal range until over 1 L of blood has been lost. A significant decrease in blood pressure along with marked tachycardia (>120 bpm) may not be seen until 30% to 40% of blood volume has been lost, or 2.0 to 2.6 L in a healthy term pregnant patient, after which the patient may rapidly decompensate. In resource-poor settings especially, the narrow window between the emergence of significant vital sign abnormalities and clinical decompensation may prove catastrophic. Once hemorrhage is detected, decisions regarding blood product transfusion are routinely made on the basis of inaccurate estimates of blood loss, placing patients at risk of underresuscitation (increasing the risk of hemorrhagic shock and end-organ damage) or overresuscitation (increasing the risk of transfusion reaction, fluid overload, and alloimmunization). We will review novel technologies that have emerged to assist both in the early and accurate detection of postpartum hemorrhage and in decisions regarding blood product transfusion.

Investigation of The Effects of Oxytocin Administration Timing on Postpartum Hemorrhage during Cesarean Section. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59020222.

Abstract
Background and Objectives: To determine and compare the effects of the timing of oxytocin administration (routinely used for intraoperative uterotonic purposes in cesarean section (CS) deliveries in our clinic) on the severity of postpartum hemorrhage following CS. Materials and Methods: All study participants (n = 216) had previous cesarean deliveries, were 38-40 weeks pregnant, and had CS planned under elective conditions. The cases were randomly divided into two groups: one group (n = 108) receiving oxytocin administration before the removal of the placenta (AOBRP) and another group (n = 108) receiving oxytocin administration after the removal of the placenta (AOARP). In all cases, the placenta was removed using the manual traction method. The standard dose of oxytocin is administered as an intravenous (IV) push of 3 international units (IU); simultaneously, 10 IU of oxytocin is added to 1000 cc isotonic fluid and given as an IV infusion at a rate of 250 cc/h. All methods and procedures applied to both groups were identical, except for the timing of administration of the standard oxytocin dose. Age, body mass index (BMI), parity, gestational week, preoperative hemoglobin (HB) and hematocrit (HTC), postoperative 6th and 24th hour HB-HTC, intraoperative hemorrhage, additional uterotonic need during cesarean section, postoperative hemorrhage (number of pads), need for blood transfusion during or after cesarean section, cesarean section time, and postpartum newborn baby weight were evaluated. Results: Age (year), BMI (kg/m2), parity, gestational week, surgical time, and newborn weight (g) did not differ between the groups (p > 0.05). The AOBRP group had significantly higher postoperative 6th hour HB and HTC and postoperative 24th hour HB and HTC values (p < 0.05). The intraoperative hemorrhage level was higher in the AOARP group (p = 0.000). Conclusions: The administration of oxytocin before placenta removal did not change the volume of bleeding in the postoperative period but significantly reduced the volume of bleeding in the intraoperative period. Therefore, in the postoperative period, the HB and HTC values of the AOBRP group were higher than those of the AOARP group.

Abstract
Background We aimed to describe the characteristics and the pregnancy outcomes of women with rare inherited coagulation factor disorders managed at a tertiary obstetric-haematology unit in the United Kingdom. Methods A retrospective service evaluation was conducted using routinely collected medical records. Descriptive analyses were applied to investigate pregnancy, childbirth and neonatal management and outcomes. Results Overall, 20 patients with rare inherited coagulation disorders were included who birthed 30 live infants from 29 pregnancies. Regarding maternal bleeding outcomes, 3% experienced antepartum haemorrhage, 38% of pregnancies experienced primary post-partum haemorrhage, and none experienced secondary post-partum haemorrhage. Five (17%) neonates had cranial ultrasound scans for imaging to investigate for a neonatal haemorrhage, which were all normal. Conclusions Although women with rare inherited coagulation disorders may be more susceptible to complications in pregnancy, within this cohort there was no evidence that the condition led to increased morbidity or mortality when best practices were observed.

Abstract
INTRODUCTION Women and girls with bleeding disorders face multiple bleeding challenges throughout their life. The most significant morbidity and mortality are due to heavy menstrual bleeding and postpartum hemorrhage in their reproductive years. The ASH/ISTH/NHF/WFH 2021 guidelines on diagnosing and managing von Willebrand disease (VWD) provide several new updates. AREAS COVERED Women with VWD have a higher prevalence of heavy menstrual bleeding. The subpopulation of adolescents is particularly vulnerable, as the diagnosis is often delayed with increased comorbidity of iron deficiency anemia and associated symptoms. A detailed review is done on the prevalence of bleeding-related complications, especially heavy menstrual bleeding (HMB) and post-partum hemorrhage (PPH). The management strategies are also reviewed in detail, with a specific focus on the target factor levels and the use of antifibrinolytics. EXPERT OPINION The 2021 ASH/ISTH/NHF/WFH diagnostic and management recommendations are reviewed with a specific focus on hormonal methods of HMB management and antifibrinolytics in this situation. The reviewed topics include neuraxial anesthesia, factor cutoff, and tranexamic acid use in the postpartum period.

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
Major haemorrhage is a leading cause of morbidity and mortality worldwide. Successful treatment requires early recognition, planned responses, readily available resources (such as blood products) and rapid access to surgery or interventional radiology. Major haemorrhage is often accompanied by volume loss, haemodilution, acidaemia, hypothermia and coagulopathy (factor consumption and fibrinolysis). Management of major haemorrhage over the past decade has evolved to now deliver a 'package' of haemostatic resuscitation including: surgical or radiological control of bleeding; regular monitoring of haemostasis; advanced critical care support; and avoidance of the lethal triad of hypothermia, acidaemia and coagulopathy. Recent trial data advocate for a more personalised approach depending on the clinical scenario. Fresh frozen plasma should be given as early as possible in major trauma in a 1:1 ratio with red blood cells until the results of coagulation tests are available. Tranexamic acid is a cheap, life-saving drug and is advocated in major trauma, postpartum haemorrhage and surgery, but not in patients with gastrointestinal bleeding. Fibrinogen levels should be maintained > 2 g.l-1 in postpartum haemorrhage and > 1.5 g.l-1 in other haemorrhage. Improving outcomes after major traumatic haemorrhage is now driving research to include extending blood-product resuscitation into prehospital care.
