Comparison of Side Effects of Misoprostol by Oral and Rectal Routes in Active Management of Third Stage of Labour

Background Postpartum haemorrhage (PPH) is the leading cause of maternal mortality worldwide. Prophylactic uterotonic agents can prevent PPH, and are routinely recommended. The current World Health Organization (WHO) recommendation for preventing PPH is 10 IU (international units) of intramuscular or intravenous oxytocin. There are several uterotonic agents for preventing PPH but there is still uncertainty about which agent is most effective with the least side effects. This is an update of a Cochrane Review which was first published in April 2018 and was updated to incorporate results from a recent large WHO trial. Objectives To identify the most effective uterotonic agent(s) to prevent PPH with the least side effects, and generate a ranking according to their effectiveness and side‐effect profile. Search methods We searched the Cochrane Pregnancy and Childbirth’s Trials Register, , the World Health Organization (WHO) International Clinical Trials Registry Platform ( ) (24 May 2018), and reference lists of retrieved studies. Selection criteria All randomised controlled trials or cluster‐randomised trials comparing the effectiveness and side effects of uterotonic agents with other uterotonic agents, placebo or no treatment for preventing PPH were eligible for inclusion. Quasi‐randomised trials were excluded. Randomised trials published only as abstracts were eligible if sufficient information could be retrieved. Data collection and analysis At least three review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. We estimated the relative effects and rankings for preventing PPH ≥ 500 mL and PPH ≥ 1000 mL as primary outcomes. Secondary outcomes included blood loss and related outcomes, morbidity outcomes, maternal well‐being and satisfaction and side effects. Primary outcomes were also reported for pre‐specified subgroups, stratifying by mode of birth, prior risk of PPH, healthcare setting, dosage, regimen and route of administration. We performed pairwise meta‐analyses and network meta‐analysis to determine the relative effects and rankings of all available agents. Main results The network meta‐analysis included 196 trials (135,559 women) involving seven uterotonic agents and placebo or no treatment, conducted across 53 countries (including high‐, middle‐ and low‐income countries). Most trials were performed in a hospital setting (187/196, 95.4%) with women undergoing a vaginal birth (71.5%, 140/196). Relative effects from the network meta‐analysis suggested that all agents were effective for preventing PPH ≥ 500 mL when compared with placebo or no treatment. The three highest ranked uterotonic agents for prevention of PPH ≥ 500 mL were ergometrine plus oxytocin combination, misoprostol plus oxytocin combination and carbetocin. There ...
