- Successful labor induction [ Time Frame: Eleven hours of initiating oxytocin on the fist day of induction ]Induction success was defined as an ability to achieve the active phase of labor corresponding to a cervical dilatation of ≥ 4 cm within 11 hours of initiating oxytocin (i.e., within 22 hours of the administration of a dinoprostone vaginal insert) on the first day of induction.
- the need for oxytocin induction [ Time Frame: After removing prostaglandin, the following day when an intravenous oxytocin infusion was started ]
- the interval from start of oxytocin to the active phase of labor
- the interval from start of oxytocin to delivery
- vaginal delivery within 24 hours of starting induction
- the incidence of cesarean delivery
