Overview
Brief Summary
This is a prospective, randomized trial looking at the ideal method of labor induction for women with prelabor rupture of membranes and an unfavorable cervical Bishop score. The study will compare oral misoprostol and intravenous oxytocin.
Detailed Description
The purpose of this study is to look at optimal induction management of prelabor rupture of membranes (PROM) at or beyond 34 weeks gestational age. Objective 1: To determine if there is a decrease in time from initiation of induction of labor to vaginal delivery in women with an unfavorable cervix with the use of oral misoprostol versus intravenous oxytocin. Hypothesis: Cervical ripening with misoprostol will be beneficial in women with an unfavorable cervix. Sub objective 1: To determine if the use of oral misoprostol for cervical ripening decreases the rate of postpartum hemorrhage in women with PROM. Hypothesis: Misoprostol use will result in significantly lower rate of postpartum hemorrhage. Sub objective 2: To evaluate the rates of infectious morbidity in peripartum women and neonates exposed to misoprostol versus oxytocin in PROM. Hypothesis: The use of oral misoprostol will result in lower rates of infectious morbidity in mother and neonate. Sub objective 3: To analyze patient satisfaction surveys. Hypothesis: Patients in the oral misoprostol group will be more satisfied with their labor experience. Exploratory Outcome To determine if there is a difference in cost between induction of labor in women with an unfavorable cervix with the use of oral misoprostol versus intravenous oxytocin. Hypothesis: The use of oral misoprostol will be cost effective in women presenting with PROM and an unfavorable cervix.

Arms & Interventions
oral misoprostol
At time of delivery, participants randomly assigned to either oral misoprostol will receive 50 mcg of Misoprostol every 4 hours up to 6 doses, OR until simplified Bishop score \>6 (whichever is achieved first).
Intervention: Misoprostol Oral Product
intravenous oxytocin
At time of delivery, participants randomly assigned to intravenous oxytocin, will be administered the drug per standard of labor and delivery titrations.
Intervention: Intravenous Oxytocin
