Treatment and study plan

Assessment of cervical status

Other

Assessment of cervical status based on Bishop score versus sonographically measured cervical length

Primary outcomes

  1. 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.

Secondary outcomes

  1. 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
