Risk of uterine rupture in labor induction of patients with prior cesarean section: an inner city hospital experience - 25/08/11
Abstract |
Objective |
This study was undertaken to determine the risk of uterine rupture in patients induced with oxytocin or misoprostol after 1 or more previous cesarean sections.
Study design |
Patients with 1 or more previous cesarean sections who delivered after 28 weeks' gestation between 1996 and 2002 were identified by database. Among 3533 total patients, rates of uterine rupture were compared among 4 groups: oxytocin induction (n=430), misoprostol induction (n=142), spontaneous labor (n=2523), and repeat cesarean section without labor (n=438). Statistical analysis included χ2 test, Fisher exact test, unpaired t test, and Mantel-Haenszel test.
Results |
Rate of rupture was increased in all inductions compared with that of the spontaneous labor group. Among patients with 1 prior cesarean, rupture rates with misoprostol and oxytocin induction were 0.8% and 1.1%, respectively.
Conclusion |
Induction of labor with oxytocin or misoprostol is associated with a higher rate of uterine rupture compared with those who deliver after spontaneous labor. After 1 prior cesarean, rupture rate with misoprostol induction is not increased compared with oxytocin induction.
