Study of the Effectiveness of Cervical Ripening Balloon With and Without Oxytocin

Randomized Controlled Trial: Cervical Ripening Balloon With and Without Oxytocin for Cervical Ripening in Multiparas

Study Purpose: The purpose of this study is to determine the optimal method for induction of labor in multiparous women who present with an unfavorable cervix.

Hypothesis: Our hypothesis is that using oxytocin while the cervical ripening balloon is in place will result in more rapid labor courses, without increasing morbidity or increasing the need for operative delivery.

Inclusion Criteria:

• Age > 18 years
• Gestational age > 34 + 0/7 weeks

Exclusion Criteria:

• Any contraindication to cervical ripening balloon, pitocin, or vaginal delivery
• Placenta within 2 cm of cervical os
• Placental abruption, chorioamninoitis, or systemic infection prior to induction
• Rupture of membranes prior to induction ->1 prior C/S
