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.

Further study details as provided by Columbia University:

Primary Outcome Measures:
  • Delivery rate (proportion) [ Time Frame: Within 24 hours ]

Secondary Outcome Measures:
  • vaginal delivery rate [ Time Frame: within 24 hours ]
  • use of anesthesia/analgesia [ Time Frame: during induction and labor ]
  • overall complication rate (composite)
  • duration of induction and labor

Enrollment: 200
Study Start Date: November 2003
Study Completion Date: October 2005
Detailed Description:
This is a prospective, randomized trial that aims to enroll 200 singleton pregnancies presenting for preinduction ripening. Patients will be randomized to receive either TFC alone (control) or TFC plus low-dose oxytocin (treatment). Providers will not blinded to use of oxytocin and labor was managed according to routine obstetric protocols. This study is powered to detect a 20% difference in the proportion of patients delivered within 24 hours, the primary outcome. Secondary outcomes are related to vaginal delivery rate, duration of induction, complications, and pain management.
