Cervical Ripening With Cook Catheter Plus Low Dose Oxytocin
A study testing Cook catheter and Oxytocin in people with Cervical Ripening, run by Henry Ford Health System.
Trial summary
The purpose of this study is to compare if using a Cook Cervical Ripening Balloon in conjunction with low dose oxytocin is more effective at shortening labor induction times than the Cook Cervical Ripening Balloon alone. Read more about this study

About this study
The purpose of this study is to compare if using a Cook Cervical Ripening Balloon in conjunction with low dose oxytocin is more effective at shortening labor induction times than the Cook Cervical Ripening Balloon alone. After obtaining consent, patients will be randomly divided into a Balloon with oxytocin or Balloon only group. The Balloon will be placed by either Resident or Attending Physicians and left in place for 12 hours (protocol) in both groups or until it falls out. After either 12 hours or the Balloon falls out, oxytocin will be used for the remainder of the induction per current hospital protocol. Time to delivery, mode of delivery, average number of hours Balloon remained in place, non-reassuring fetal heart tracings, adverse outcomes (ie fetal malpresentation, postpartum hemorrhage) will be recorded.
