Women with singleton pregnancy in cephalic presentation at term (37-41 6/7 weeks gestational age) will be randomised 4 to 12 hours after PROM when a sterile vaginal exam will be completed to assign Bishop score. When Bishop score at presentation will be ≤5, the study will be presented to the patient. Once the patient will be consented and randomized, women will receive dinoprostone vaginal delivery system (for up to 24 hours after randomisation) or will be managed expectantly (for up to 24 hours after randomisation).~Patients randomized to the expectant management group will be admitted to the maternity ward, where they will wait up to a maximum of 24 hours for labor to start spontaneously.~Patients in the induction group will also be admitted to the maternity ward and induced with a dinoprostone vaginal delivery system. If not removed sooner, the vaginal delivery system will be removed after 24h.~If patients in both groups will not be in active labor 24 hours after randomisation they will be admitted to the delivery room and health care providers will manage active labor per usual practice. The need for cesarean section or operative delivery or will be at the discretion of the healthcare provider.~In the days following birth, woman in both groups, will be asked to fill in a questionnaire about their satisfaction with the labour experience.
Prelabour rupture of membranes (PROM) is associated with intrauterine infection and maternal and neonatal consequences. This risk increases with the length of time from PROM to delivery. Induction of labor has been shown to reduce the rates of those complications, however the optimal time interval has not yet been determined.~The main purpose of this single-center randomized prospective study is to assess the differences between two approaches of managing PROM at term-expectant management and induction with a dinoprostone vaginal delivery system.
