Induction of labor at 38 to 39 weeks of gestation reduces the incidence of shoulder dystocia in gestational diabetic patients class A2.
The purpose of this study was to test the hypothesis that the incidence of shoulder dystocia could be reduced in insulin-requiring diabetic women by elective induction of labor at 38 to 39 weeks of gestation. A prospective study protocol in which labor was induced at 38 to 39 weeks of gestation in insulin-requiring diabetic women was executed between January 1, 1990, and July 31, 1994 (n = 96). The outcome was compared to the results of a previous protocol (years 1983 to 1989) in which the pregnancies were allowed to progress to spontaneous labor, unless fetal health became compromised (n = 164). The incidence of shoulder dystocia in patients in whom labor was electively induced at 38 to 39 weeks of gestation was 1.4% as compared to 10.2% in patients who delivered beyond 40 weeks' gestation (p < 0.05). No increase in cesarean section rate was demonstrated. We conclude that elective induction of labor is suggested for insulin-requiring diabetic women in order to reduce the incidence of shoulder dystocia.
