- Primary Outcome Measures
Name Time Method Successful labor induction 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.
- Secondary Outcome Measures
Name Time Method the need for oxytocin induction After removing prostaglandin, the following day when an intravenous oxytocin infusion was started 1. the interval from start of oxytocin to the active phase of labor
2. the interval from start of oxytocin to delivery
3. vaginal delivery within 24 hours of starting induction
4. the incidence of cesarean delivery
