About
The goal of this randomized control trial is to compare different doses of Misoprostol (25 mcg vs 50 mcg) in induction of labor (IOL) in morbidly obese patients with BMI >40. It is known that morbid obesity is a risk factor for failed IOL and ultimately cesarean delivery (CD.) If the rates of vaginal delivery in this population can improve, then surgical morbidity can be reduced in these patients.
Full description
The rate of IOL continues to increase, from about 10% in 1990 to 23% in 2018. Patients with BMI >40 are at increased risk for failed IOL and needing a CD. Studies show that morbidly obese patients require higher doses of pitocin and multiple agents to achieve vaginal delivery, but optimal dosing of misoprostol has not been studied as well. Increasing the rate of vaginal delivery in this population will help decrease risk of surgical morbidity.
The investigators plan to conduct a randomized controlled double blinded trial. Patients who are scheduled for induction of labor after 34 weeks gestation, have a BMI >40, and meet all study inclusion criteria will be approached by research personnel during their outpatient appointments. Participants will be randomized to either receive 25 mcg vaginal misoprostol every 4 hours or 50 mcg vaginal misoprostol every 4 hours.
