oxytocin and Maternal-Death

Prevention of deaths from obstetric haemorrhage requires effective health systems including family planning, commodities, personnel, infrastructure and ultimately universal access to comprehensive obstetric care for women giving birth. The main causes of death associated with antepartum haemorrhage are placental abruption, placenta praevia and uterine rupture. Preventive measures include preconceptual folate supplementation, management of hypertensive disorders, early diagnosis of placenta praevia and use of uterine stimulants cautiously, particularly misoprostol. Preventive measures for post-partum haemorrhage include routine active management of the third stage of labour. Treatment involves a cascade of increasingly invasive interventions in rapid sequence until the bleeding is stopped. These interventions include fluid resuscitation, removal of the placenta, bimanual uterine compression, uterotonics, tranexamic acid, suturing of lower genital tract injury, blood product replacement, balloon tamponade, laparotomy, stepwise uterine devascularization, uterine compression sutures and hysterectomy. Emergency temporizing measures include application of the non-pneumatic anti-shock garment, and at laparotomy, aortic compression and uterine tourniquet application. The effectiveness of treatment methods and the optimal dosage of misoprostol are research priorities. Interesting new approaches include transvaginal uterine artery clamping and suction uterine tamponade.

Maternal deaths due to haemorrhage continue to increase in South Africa (SA). It appears that oxytocin and other uterotonics are not being used optimally, even though they are an essential part of managing maternal haemorrhage. Oxytocin should be administered to every mother delivering in SA. Awareness is required of the side-effects that can occur and the appropriate measures to avoid harm from these. Second-line uterotonics should also be available and utilised in conjunction with mechanical and surgical means to arrest haemorrhage in women who continue to bleed after the appropriate administration of oxytocin.

Postpartum hemorrhage (PPH) is a major cause of maternal morbidity, and oxytocin is the first-line uterotonic agent for PPH prevention. Clinical findings have reported carbetocin to reduce PPH risk without increasing risk of important side effects. Hong Kong is a low PPH burden and high-resource city in China. We aimed to examine the cost-effectiveness of PPH prevention with carbetocin from the perspective of Hong Kong public healthcare provider.. A decision-analytic model was developed to simulate clinical and economic outcomes of carbetocin and oxytocin for PPH prevention in a hypothetical cohort of women at the third stage of labor following vaginal birth or Caesarean section (C-section). The model inputs were retrieved from literature and public data. Base-case analysis and sensitivity analysis were performed. The model time horizon was the postpartum hospitalization period. Primary model outcomes included PPH-related direct medical cost, PPH, hysterectomy, maternal death, and quality-adjusted life-year (QALY) loss.. In base-case analysis, carbetocin (versus oxytocin) reduced PPH-related cost (by USD29 per birth), PPH ≥500 mL and ≥1,500 mL (by 13.7 and 1.9 per 1,000 births), hysterectomy (by 0.15 per 1,000 births), maternal death (by 0.02 per 1,000 births), and saved 0.00059 QALY per birth. Relative risk of PPH ≥500 mL with carbetocin versus oxytocin, and proportion of child births by C-section were two influential parameters identified in deterministic sensitivity analysis. In probabilistic sensitivity analysis, carbetocin was accepted as cost-effective in >99.7% of the 10,000 Monte Carlo simulations at a willingness-to-pay threshold of zero USD/QALY.. PPH prevention with carbetocin appeared to reduce major unfavorable outcomes, and save cost and QALYs.

A descriptive study was conducted to investigate the epidemiology and the outcome of uterine rupture at Hajjah Hospital, Yemen, during September 2014-August 2016. There were 110 cases of ruptured uterus and 3457 deliveries (31.8 per 1000 delivery). The majority (82, 74.5%) of these patients were illiterate. One hundred and four (96.3%) of them had no antenatal care. Seventy-eight of these women (70.9%) delivered at home and 32 (29.1%) delivered at hospital. Out of these 110 cases, 74 (67.3%) and 36 (32.7%) had unscarred uterus and scarred uterus, respectively. The causes of ruptured uterus were as follows: obstructed labour 59 (53.6%), previous caesarean delivery 36 (32.7%), use of oxytocin 10 (9.1%) and misoprostol 5 (4.6%). Hysterectomy was carried out in 50 (45.4%) %), repair in 39 (35.4%), repair with tubal ligation in 18 (16.4%) patients and 3 (2.7%) patients died before operation. There was 8 (7.2%) and 101 (91.8%) maternal and perinatal mortality, respectively. Nineteen (17.3%), 6 (5.4%) and 2 (1.8%) women developed sepsis, had urinary bladder injury and developed vesicovaginal fistulae, respectively.

Postpartum haemorrhage (PPH) is a major cause of maternal mortality. Prevention and adequate treatment are therefore important. However, most births in low-resource settings are not attended by skilled providers, and knowledge and skills of healthcare workers that are available are low. Simulation-based training effectively improves knowledge and simulated skills, but the effectiveness of training on clinical behaviour and patient outcome is not yet fully understood. The aim of this study was to assess the effect of obstetric simulation-based training on the incidence of PPH and clinical performance of basic delivery skills and management of PPH.. A prospective educational intervention study was performed in a rural referral hospital in Tanzania. Sixteen research assistants observed all births with a gestational age of more than 28 weeks from May 2011 to June 2013. In March 2012 a half-day obstetric simulation-based training in management of PPH was introduced. Observations before and after training were compared. The main outcome measures were incidence of PPH (500-1000 ml and >1000 ml), use and timing of administration of uterotonic drugs, removal of placenta by controlled cord traction, uterine massage, examination of the placenta, management of PPH (>500 ml), and maternal and neonatal mortality at 24 h.. Three thousand six hundred twenty two births before and 5824 births after intervention were included. The incidence of PPH (500-1000 ml) significantly reduced from 2.1% to 1.3% after training (effect size Cohen's d = 0.07). The proportion of women that received oxytocin (87.8%), removal of placenta by controlled cord traction (96.5%), and uterine massage after birth (93.0%) significantly increased after training (to 91.7%, 98.8%, 99.0% respectively). The proportion of women who received oxytocin as part of management of PPH increased significantly (before training 43.0%, after training 61.2%). Other skills in management of PPH improved (uterine massage, examination of birth canal, bimanual uterine compression), but these were not statistically significant.. The introduction of obstetric simulation-based training was associated with a 38% reduction in incidence of PPH and improved clinical performance of basic delivery skills and management of PPH.

PATH, an international nonprofit organization, assessed nearly 40 technologies for their potential to reduce maternal mortality from postpartum hemorrhage and preeclampsia and eclampsia in low-resource settings. The evaluation used a new Excel-based prioritization tool covering 22 criteria developed by PATH, the Maternal and Neonatal Directed Assessment of Technology (MANDATE) model, and consultations with experts. It identified five innovations with especially high potential: technologies to improve use of oxytocin, a uterine balloon tamponade, simplified dosing of magnesium sulfate, an improved proteinuria test, and better blood pressure measurement devices. Investments are needed to realize the potential of these technologies to reduce mortality.
