INTRODUCTION

A recent retrospective review of hospital discharge data found what appeared to be a marked increase in uterine rupture rates when prostaglandins were used for cervical ripening in vaginal birth after cesarean (VBAC) patients.1 However, the study had serious limitations that were appropriately acknowledged by its authors and subsequently reviewed in a published critique.2 In spite of the study’s limitations, the American College of Obstetrics and Gynecology (ACOG) responded by publishing a Committee Opinion stating that, “The purpose of this document is to discourage the use of prostaglandins for cervical ripening or the induction of labor in women attempting VBAC.3 This opinion will no doubt be controversial because both a large multicenter study and a review of many smaller studies did not find any increased risk with prostaglandin use in VBAC patients.4,5
