High Volume Foleys Increasing Vaginal Birth Pilot Trial

Summary

It is currently unknown if there is a way to decrease the risk of cesarean delivery when undergoing cervical ripening and induction of labour. Some research suggests a Foley catheter placed through the cervix and filled to 80cc may decrease this risk. We wish to run a large scale trial to see if Foleys filled to 80cc decrease the risk of Cesarean section compared to the commonly used medication for cervical ripening, prostaglandins. Before we can undertake a large trial, we need to do a pilot to see if women will agree to participate in this type of study. As well, a pilot will help with trouble shooting prior to a large trail, to improve the chances of successfully answering this clinically important question.
