![]() The studies reported several varying outcomes for both maternal and foetal morbidities meta-analyses. There was no difference in rates of cesarean delivery or serious maternal-fetal events compared with no intervention, prostaglandin administration, or oxytocin administration, although patients who underwent membrane sweeping had more minor bleeding and irregular contractions. The results revealed that membrane sweeping is advantageous in promoting spontaneous labour (RR 1.205, 95 CI: 1.133-1.282, p <.001), and reducing the formal induction of labour for postmaturity (RR 0.523, 95 CI: 0.409-0.669, p <.001). Time to spontaneous delivery was 2.5 days shorter in the intervention group (10 trials N = 1,580 mean difference = −2.5 95% confidence interval, −3.0 to −2.0), and there was a decreased need for formal labor induction (12 trials N = 1,493 risk ratio = 0.28 95% CI, 0.15 to 0.5). 1 Sweeping was primarily compared with no intervention, although several small trials compared it with prostaglandin or oxytocin (Pitocin) administration. ![]() A 2005 Cochrane review evaluated membrane sweeping for induction of labor in 22 RCTs with a total of 2,797 pregnant women at term. It involves inserting a finger into the cervical os and sweeping it circumferentially to separate the fetal membranes from the uterus. Membrane sweeping or stripping is routinely used in late pregnancy.
