Not Applicable
Completed
Conditions
Pre-induction Cervical Ripening
Interventions
Device: mechanical pre-induction cervical ripening
Registration Number
NCT02344459
Lead Sponsor

Brief Summary

The purpose of this study is to perform a randomized controlled trial to compare the efficacy of 80mL double balloon catheter versus a 30mL single catheter balloon for pre-induction cervical ripening by evaluating the change in Bishop score.
