A Cochrane review [Abstract] 1 included 44 trials and 6 940 women. Compared with no treatment/sham, membrane sweeping increased spontaneous onset of labour (average risk ratio [aRR] 1.21, 95% CI 1.08 to 1.34, 17 studies, n=3170). Risk of caesarean section (aRR 0.94, 95% CI 0.85 to 1.04, 32 studies, n=5499), spontaneous vaginal birth (aRR 1.03, 95% CI 0.99 to 1.07, 26 studies, n=4538), maternal death or serious morbidity (aRR 0.83, 95% CI 0.57 to 1.20, 17 studies, n=2749), and neonatal perinatal death or serious morbidity (aRR 0.83, 95% CI 0.59 to 1.17, 18 studies, n=3696) were similar between groups. There were little or no difference fot those outcomes when sweeping of the membranes were compared with with vaginal/intracervical prostaglandins (4 trials, n= 480).
A meta-analysis 3 included 7 studies with a total of 2252 participants. The meta-analysis assessed efficacy and the safety of membrane sweeping in promoting spontaneous labour and reducing a formal induction of labour for postmaturity. Membrane sweeping was advantageous in promoting spontaneous labour (RR 1.20, 95% CI 1.133 to 1.282, p = <.001), and reducing the formal induction of labour for postmaturity (RR 0.523, 95% CI:0.409- to .669, p = <.001).
