Primary
| Measure | Time frame |
|---|---|
| Successful induction of labour -defined as, an ability to achieve the active phase of labour corresponding to a cervical dilatation of >4 cm after one cycle of the administration of a dinoprostone vaginal pessary on the first day of induction with regular uterine contractions.(three or more moderate contractions per 10 min.) [14 hours after first prostaglandin insertion] | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Interval from start of induction by amniotomy to any type of delivery 2. Interval from time of insertion of prostaglandins to vaginal delivery 3. Need for oxytocin augmentation after amniotomy 4. Interval from time of insertion of prostaglandins to beginning of active phase 5. Number of women with spontaneous rupture of membranes and interval from time of insertion of prostaglandins to this event 6. Route of delivery 7. Number of women with cesarean section for failed induction 8. Meconium passage 9. Birth weight 10. Apgar scores 11. Number of infants admitted to neonatal intensive care unit. 12.
