ObjectiveTo describe the incidence, indications, risk factors, outcomes, and management of emergency peripartum hysterectomy globally and to compare outcomes among different income settings.Data sourcesPubMed, MEDLINE, EMBASE, ClinicalTrials.gov, Cochrane Library, Web of Science, and Emcare databases up to December 10, 2021.Methods of study selectionUpdate of a systematic review and meta-analysis (2016). Studies were eligible if they reported the incidence of emergency peripartum hysterectomy, defined as surgical removal of the uterus for severe obstetric complications up to 6 weeks postpartum. Title and abstract screening and full-text review were performed using Endnote data-management software. Of 8,775 articles screened, 26 were included that were published after 2015, making the total number of included studies 154. A subanalysis was performed for the outcomes of interest per income setting.Tabulation, integration, and resultsThe meta-analysis included 154 studies: 14,409 emergency peripartum hysterectomies were performed in 17,127,499 births in 42 countries. Overall pooled incidence of hysterectomy was 1.1 per 1,000 births (95% CI 1.0-1.3). The highest incidence was observed in lower middle-income settings (3/1,000 births, 95% CI 2.5-3.5), and the lowest incidence was observed in high-income settings (0.7/1,000 births, 95% CI 0.5-0.8). The most common indications were placental pathology (38.0%, 95% CI 33.9-42.4), uterine atony (27.0%, 95% CI 24.6-29.5), and uterine rupture (21.2%, 95% CI 17.8-25.0). In lower middle-income countries, uterine rupture (44.5%, 95% CI 36.6-52.7) was the most common indication; placental pathology (48.4%, 95% CI 43.5-53.4) was most frequent in high-income settings. To prevent hysterectomy, uterotonic medication was used in 2,706 women (17%): 53.2% received oxytocin, 44.6% prostaglandins, and 17.3% ergometrine. Surgical measures to prevent hysterectomy were taken in 80.5% of women, the most common being compressive techniques performed in 62.6% (95% CI 38.3-81.9). The most common complications were febrile (29.7%, 95% CI 25.4-34.3) and hematologic (27.5%, 95% CI 20.4-35.9). The overall maternal case fatality rate was 3.2 per 100 emergency peripartum hysterectomies (95% CI 2.5-4.2) and was higher in lower middle-income settings (11.2/100 emergency peripartum hysterectomies 95% CI 8.9-14.1) and lower in high-income settings (1.0/100 emergency peripartum hysterectomies 95% CI 0.6-1.6).ConclusionSubstantial differences across income settings exist in the incidence of emergency peripartum hysterectomy. Women in lower-income settings have a higher risk of undergoing emergency peripartum hysterectomy and suffer more procedure-related morbidity and mortality. The frequency of emergency peripartum hysterectomy is likely to increase in light of increasing cesarean delivery rates.

1.ObjectiveTo perform a network meta-analysis to specify the route of administration that maximises the effectiveness of each of the available prophylactic uterotonics without increasing the risk for side effects. 2.Data sourcesLiterature searches on 12th September 2022 included: CENTRAL, MEDLINE, Embase, CINAHL, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform. The reference lists of the retrieved study records were also searched. 3.Study eligibility criteriaPopulation: Randomized controlled trials involving women in the third stage of labour after a vaginal or caesarean delivery in hospital or community settings.InterventionsSystemically administered prophylactic uterotonics of any route and dose for primary postpartum hemorrhage prevention. Comparison: Any other prophylactic uterotonic, or a different route or dose of a given uterotonic, or placebo, or no treatment. Outcomes (primary): postpartum hemorrhage ≥ 500 mL and ≥ 1000 mL. 4.Study appraisal and synthesis methodsRisk of bias and trustworthiness assessments were performed, according to Cochrane's guidance. Direct, indirect and network meta-analyses were conducted, and results were summarized either as risk ratio or mean difference with 95% confidence intervals for dichotomous and continuous outcomes, respectively. The certainty of generated evidence was assessed according to the GRADE approach. Cumulative probabilities were calculated and the surface under the cumulative ranking curve was used to create a ranking of the available drugs. 5.ResultsOne hundred eighty-one studies involving 122,867 randomised women were included. Most studies were conducted in hospital settings in lower-middle income countries and involved women delivering vaginally. When compared with intramuscular oxytocin, carbetocin (RR 0.58, 95 % CI 0.40-0.84) and oxytocin (RR 0.75, 95 % CI 0.59-0.97) by an intravenous bolus, and intramuscular ergometrine plus oxytocin combination (RR 0.71, 95 % CI 0.56-0.91) are probably more effective in preventing primary postpartum hemorrhage. Intramuscularly administered oxytocin and carbetocin by an intravenous bolus have a favourable side effects profile. 6.ConclusionsGenerated evidence was generally moderate and global inconsistency was low. Carbetocin and oxytocin by an intravenous bolus, and intramuscular ergometrine plus oxytocin combination are probably the top uterotonics for primary postpartum hemorrhage prevention. Large scale studies exploring different routes of administration for available prophylactic uterotonics, and women's views should be conducted.

Postpartum haemorrhage (PPH) is a leading cause of maternal death. Preventing PPH can spare women from experiencing the trauma and risks of PPH, reduce the strain on overstretched health systems, and probably produce better outcomes than a strategy solely focused on PPH treatment. Prevention of PPH is often interpreted as provision of uterotonic drugs to contract the uterus at the time of childbirth. Although uterotonics are a central strategy for PPH prevention, several other approaches can prevent PPH or ameliorate its severity. These approaches include addressing the unmet need for contraception, remedying anaemia and other modifiable risk factors for PPH, optimising medical conditions that predispose to PPH, and tackling the rise in caesarean births in many countries. Effective delivery of preventive care requires early and regular antenatal care and planned birth at appropriately resourced health facilities. Social and behavioural change interventions for improving contraceptive provision and uptake, targeting adolescents, postpartum women, geographically remote communities, and families on low income, are a priority. Effective interventions to tackle anaemia include the management of heavy menstrual bleeding, pre-pregnancy or antenatal haemoglobin testing and oral or intravenous iron treatment, dietary improvements, and-on rare occasions-blood transfusion. Risk factors for PPH that need attention include high BMI, multiple pregnancy, gestational diabetes, pre-eclampsia, macrosomia, and several medical conditions. Caesarean births are associated with a substantial increase in PPH risk and should therefore only be done when medically indicated. A Cochrane network meta-analysis of 122 trials, with 121 931 women, found that the combinations of oxytocin plus misoprostol, or oxytocin plus ergometrine, were the most effective prophylaxis for PPH when given at the time of childbirth; however, these combinations had a higher risk of side-effects compared with single-drug prophylaxis. Oxytocin and carbetocin were the most effective single drugs for PPH prophylaxis, with minimal side-effects. Single uterotonic prophylaxis with either oxytocin or carbetocin is, therefore, recommended for routine prophylaxis. However, if oxytocin or carbetocin is not accessible, misoprostol is an alternative. Combination prophylaxis with oxytocin plus misoprostol can be considered for women at high risk of PPH. Ergometrine alone and oxytocin plus ergometrine combination are no longer recommended due to hypertension-related safety concerns. A robust implementation approach that engages various stakeholders to promote change, ensures the supply of quality-assured medicines and devices, provides training and support, and secures ongoing political and financial commitment is necessary to translate evidence into global impact.
