The role of membrane stripping in prevention of post-term pregnancy: a randomised clinical trial in Ile-lfe, Nigeria.

This study was carried out to evaluate the efficacy and safety of membrane stripping at term in reducing the incidence of post-term (41 weeks or greater) pregnancies. One hundred and thirty-seven pregnant women at 38 weeks gestation were randomised to receive either membrane stripping (69) or gentle cervical examination (68). Women who received stripping had earlier delivery (4.8 vs. 12.1 days; P<0.001) and less incidence of delivery at 41 weeks or greater (3% vs. 16%; P=0.009). No statistically significant difference was noted in incidence of premature rupture of membranes, clinical evidence of chorioamnionitis, intrapartum characteristics and perinatal outcome. We conclude that membrane stripping is a safe method to reduce the incidence of post-term pregnancy.
