Foley With Oxytocin Versus Foley no Oxytocin for Induction of Labor

This is a multi-center, open-label, randomized study. Women with a singleton, vertex
gestation between 24-42 weeks gestations presenting for labor induction will be offered
participation in this study. Patients who receive prenatal care at Christiana Care may be
approached if an induction of labor is scheduled and consented at their prenatal visit. All
indications for induction will be included except those specifically mentioned as exclusion
criteria. Any contraindication for vaginal delivery would exclude the subject. After
informed consent is obtained, the Foley catheter will be placed and the subject will be
randomized to receive oxytocin (study group) or not (control group). After Foley catheter
removal or expulsion, the remainder of the induction course was left to the discretion of
the primary provider. Prior to randomization, the subject will be placed into the
nulliparous or multiparous group.
