Comparison Between Two Medical Devices for Labor Induction After Previous C-section

"Cook double balloon will be introduced transcervically. The double balloon will be inflated with sterile 0-9% saline solution (maximum 80 ml in each balloon of the double device), then the catheter will be fixed with a tape at the women's thigh without traction. The catheter will remain in place until spontaneously expelled or start of active labour.~If neither happens, the device will be removed after 12-24 hours and oxytocin will be administered and amniotomy as soon as feasible. If the cervix remains unfavorable after two cycles of 6 hours of oxytocin infusion, the induction will be classified as unsuccessful and C-section will be performed."

"A maximum number of 5 hygroscopic cervical dilator rods will be inserted transcervically, after humidification with sterile 0.9% saline solution. They will be fixed in this position by inserting a humidified compress into the vagina. They will remain in place until spontaneously expelled or until start of active labour.~In neither happens, the devices will be removed after 12-24 hours and oxytocin will be administered and amniotomy as soon as feasible. If the cervix remains unfavorable after two cycles of 6 hours of oxytocin infusion, the induction will be classified as unsuccessful and C-section will be performed."
