BackgroundAmniotomy (the deliberate rupture of membranes) was described almost two centuries ago and since then has been used both for induction and augmentation of labour - which are common obstetric practices. Trends have shown a rise in the induction rates over the last decade and data suggest that the rate of labour inductions is increasing faster than the rate of pregnancy complications. Recent years have seen the emergence of a variety of other methods of induction of labour but amniotomy combined with oxytocin infusion remains the most commonly used method of augmentation of labour. The newer agents for induction are expensive and in resource-poor settings amniotomy is still the chosen method for both induction and augmentation.As with any invasive procedure amniotomy can lead to infection, ascending from the vagina into the uterine cavity and can contribute significantly to both maternal and neonatal infectious morbidity.ObjectivesThe objective of this review was to evaluate the prophylactic use of antibiotics versus placebo or no treatment prior to amniotomy on maternal and neonatal infectious morbidity and mortality.Search MethodsWe searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 August 2014), the International Clinical Trials Registry Platform (ICTRP) and ClinicalTrials.gov (12 September 2014).Selection CriteriaRandomised controlled trials or cluster-randomised trials comparing antibiotics prior to amniotomy versus placebo (or no treatment) were eligible for inclusion in this review but none were identified. Quasi-randomised trials or cross-over trials were not eligible for inclusion.Data Collection And AnalysisTwo review authors independently assessed one trial report for inclusion. In future updates of this review, two review authors will independently assess risk of bias and carry out data extraction. Data will be checked for accuracy.Main ResultsWe identified one trial report but this was excluded. No studies met the inclusion criteria for this review.Authors' ConclusionsHigh-quality trials are needed to justify or refute the routine use of antibiotics at amniotomy for prevention of infection in the mother and infant.Future studies should be conducted, especially in resource-constrained settings where amniotomy is still used as a means of induction of labour, in order to evaluate the routine use of antibiotics at amniotomy in these settings. Future research in this area should include important maternal and infant outcomes listed in this review and also consider cost effectiveness and side effects of antibiotic use, including the emergence of antibiotic-resistant strains.
