A Comparison of Oral Misoprostol and Vaginal Misoprostol for Cervical Ripening and Induction of Labor
Study Details
Study Description
Brief Summary
The purpose of this study is to study if misoprostol administered orally is at least as effective as misoprostol administered vaginally for cervical ripening and the induction of labor. The main purpose is to show that oral misoprostol administration is non-inferior to vaginal misoprostol administration with respect to the time interval from misoprostol administration to onset of active phase of labor. The study is a non-inferiority, prospective randomized controlled trial comparing oral misoprostol given as 25 mcg every 2 hours versus vaginal misoprostol given as 25 mcg every 4 hours.

composite outcome of Apgar score < 7, cord blood gases (pH of less than 7 or base deficit great than 12), and neonatal intensive care unit admission within 4 hours of delivery
- rate of anti-emetic use [from enrollment until delivery]
- rate of diarrhea [from enrollment until delivery]
- rate of vaginal delivery within 24 hours [24 hours from start of induction of labor (first misoprostol administration)]
- rate of abandoning misoprostol for cervical ripening and switching to mechanical dilation for cervical ripening [from enrollment until delivery]
- rate of development of preeclampsia requiring magnesium sulfate administration [from enrollment until delivery]
