title: Stripping membranes at term: can it safely reduce the incidence of post-term pregnancies?
abstract: Membrane stripping has been used clinically for many years but has not been well studied. An investigation was undertaken to determine whether weekly membrane stripping beginning at 38 weeks could safely reduce post-term pregnancies. One hundred eighty patients with firm gestational dates were randomized to either a treatment or control group. Control subjects received a gentle cervicovaginal examination each week to assess Bishop scores, whereas the treatment group also underwent weekly stripping of membranes. Women who received treatment had earlier delivery (mean +/- SEM 8.60 +/- 0.74 versus 15.14 +/- 0.83 days; P less than .0001) and fewer post-term deliveries than those in the control group (three versus 14; P less than .004). The reduction of post-term pregnancies was most notable in nulliparous women with unfavorable Bishop scores. Complications were similar in both groups. Membrane stripping was safe and was associated with earlier delivery and a decreased incidence of post-term gestation.
