About

A randomized controlled trial of mifepristone 200mg vs balloon catheter for cervical ripening.

Full description

Artificial induction of labour is currently required in 25-30% of all pregnancies, in high-resource countries. While the pharmacological modifications to the collagen matrix of the cervix, that allow it to dilate (cervical ripening) occur spontaneously in many women, allowing labour to be induced with oxytocin, in others the process needs to be triggered artificially. Cervical ripening is traditionally accomplished with prostaglandins or mechanical agents, in processes that typically require 12-24 hours of hospital stay. More recently, a limited number of hospitals have shifted towards starting the process in house, but then allowing women to return home and be re-evaluated on the following day.

The main aims this study is to compare efficacy and patient satisfaction of mifepristone vs balloon catheter for cervical ripening.
