A Comparative Study of Membrane Stripping and Nonstripping for Induction of Labor in Umbomplicated Term Pregnancy
Tannirandom Y Mail, Jumrustanasan T

A 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 randomized
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.
