Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will evaluate the insertion of double balloon device (DBD) for cervical ripening for 12 h vs 6 hours.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This randomized controlled study is designed to:

1. To assess and compare the Bishop score when removing the DBD 12 hours' vs 6hours' after insertion.
2. To compare the efficacy (vaginal delivery rate and time to VD) in the two arm groups

200 women are expected to be randomized in to two arms. One will be randomized to DBD removal after 12 hours and the other to DBD removal after 6 hours.

Each patient will sign an informed consent.

The following screening will be completed: medical and gynecological history, general physical and gynecological examination, ultrasonography to exclude contraindication to vaginal delivery or insertion if the DBD and non stress test (NST) for baseline. Bishop score will be assessed.

After confirming eligibility for study, randomization into the following groups will take place.

Insertion of the DBD and removal 6 hours following its insertion. Insertion of the DBD and removal 12 hours following its insertion.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

12 hours

This arm is the standard management that includes insertion of the DBD into the cervical canal according to manufacture guidelines, removal after 12 hours followed by artificial rupture of membranes and oxytocin infusion according to departments protocol. (a total of 10 units of oxytocin is infused, initiated with 10 cc/h, increased by 10cc every 20-30 min until 3-5 contractions are present, total of not more than 120 cc\\h)

Group Type OTHER

Intervention Type DEVICE

insertion of the double balloon device for 12 hours (standard care) vs 6 hours, following oxytocin IV infusion according local protocol guidelines as mentioned above

6 hours

Removal of the DBD after 6 hours, followed by artificial rupture of membranes and oxytocin infusion according to departments protocol. (a total of 10 units of oxytocin is infused, initiated with 10 cc/h, increased by 10cc every 20-30 min until 3-5 contractions are present, total of not more than 120 cc\\h)
