Study Arms (2)

cervical ripening balloon for 1 hour

EXPERIMENTAL

Eligible women will undergo the usual procedure of CRB insertion using a double lumen Cook cervical ripening balloon (CCRB). The CRB will be removed approximately after an hour in the intervention group and thereafter, the women will proceed amniotomy or Pitocin use at the discretion of the labor and delivery physician

Device: cervical ripening balloon for one hour

cervical ripening balloon for 12 hours

ACTIVE COMPARATOR

Eligible women will undergo the usual procedure of CRB insertion using a double lumen Cook cervical ripening balloon (CCRB). The CRB will be removed approximately after 12 hours in the control group and thereafter, the women will proceed amniotomy or Pitocin use at the discretion of the labor and delivery physician

Device: cervical ripening balloon for twelve hours

Interventions

The cervical ripening balloon will be left in place for one hour and after balloon removal the induction of labor will proceed at the discretion of the attending physician at labor and delivery room

cervical ripening balloon for 1 hour

The cervical ripening balloon will be left in place for for twelve hours and after balloon removal the induction of labor will proceed at the discretion of the attending physician at labor and delivery room

cervical ripening balloon for 12 hours
