Title: A Prospective, Randomized Trial of Transcervical Foley Catheter With or Without Oxytocin for Preinduction Cervical Ripening
Brief Summary: The transcervical Foley catheter (TFC) is a proven and effective mode of cervical ripening. It is common practice to use TFC with simultaneous low-dose oxytocin under the assumption that the combination results in a more successful labor induction. Scientific validation of this practice is lacking. We seek to determine if the addition of oxytocin to TFC improves induction success.
