RHL Commentary by A. Metin Gülmezoglu
EVIDENCE SUMMARY
The review evaluated the benefits and potential harms of administering antibiotics to women with prelabour rupture of the membranes at or near term.
Two trials with a total of 838 women were included. Both trials showed potential benefits in terms of reducing maternal infectious morbidity defined as chorioamnionitis and/or endometritis (relative risk [RR]: 0.43; 95% confidence interval [CI]: 0.23–0.82). There was inadequate evidence to reliably assess the effects on newborn outcomes particularly perinatal mortality (RR: 0.98; 95% CI: 0.14–6.89).
The trials used different parenteral antibiotic regimens (ampicillin + gentamycin and cefuroxime + clindamycin) and had different time thresholds for labour induction (12 hours and 24 hours).
Neither trial had allocation concealment. Newborn outcome assessment was blinded in one. The trials and the meta-analysis did not have sufficient statistical power to evaluate substantive outcomes reliably. The reviewers were appropriately cautious in their interpretation of the results and recommended more research.
