AbstractA prospective, randomized controlled trial was undertaken at the Department of Obstetrics and Gynecology, Faculty of Medicine, Chulalongkorn Hospital to determine whether stripping of the fetal membranes is a safe and effective method for induction of labor in uncomplicated term pregnancy. Ninety-six women were included in this study; 16 were excluded; 41 were ran- domized to a study group and 39 to a control group. Both groups had pelvic examination performed under sterile technique and a Bishop score was assessed. In the study group, membrane stripping was performed. Gentle pelvic examination for Bishop scoring was continued weekly in both groups. Thirty five of 41 women (85.4%) in the study group delivered within 7 days as compared to 22 of 39 women (56.4%) in the control group, a statistically significant difference (P = 0.004 ). A statistically significant difference was also observed with respect to the mean number of days to delivery (5.3 ± 4.9 versus 9.5 ± 5.9 days, respectively; P = 0.002). No statistically significant differences were observed in both maternal and fetal complications. In conclusion, membrane stripping is a safe and effective method for induction of labor in uncomplicated term pregnancy.
