    Induction of Labor in Morbidly Obese Patients

    Comparing different misoprostol doses to induce labor in people with severe obesity

    📍 University of Maryland Medical Center · Baltimore, MD · Get directions →

    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.
