Balloon + Oxytocin Versus Oral Misoprostol to Induce Labor in Case of PROM (RUBAPRO2)

Balloon catheter is inserted by a resident or a physician under visual control. The expected volume injected in the balloon probe is 60 mL. No traction is performed on the catheter. The catheter is left in place for a maximum of 12 hours.

Intravenous oxytocin addition (preceded or followed by epidural analgesia on patient's request) will be performed 6 hours after insertion of balloon catheter. Oxytocin is administered as an intravenous infusion (5 IU of oxytocin in 49 mL of 5% glucose\*) at the lowest possible dose with the aim of achieving a maximum of three to four contractions per ten minutes. After appropriate uterine activity has been achieved, the rate of the oxytocin infusion is decreased or stopped.

Patients will receive misoprostol 25 micrograms given orally (oral prostaglandin E1). The same dose will be given every 2 hours until beginning of labor with a maximum of 8 administrations.
