PROM (Premature Rupture Of Foetal Membrane)
Conditions
Keywords
PROM, Dinoprostone, cervical ripening device, oxytocin
Brief summary
The objective is to demonstrate the superiority of the strategy of labor induction by Cook® cervical ripening balloon between recommended strategy by dinoprostone (propess®) on the reduction of the time between cervical ripening and delivery in case of unfavorable cervix after 12 hours of PROM in term pregnant women.
Detailed description
The inclusion begins after 12 hours of PROM for a pregnant woman who has an unfavourable cervix and no B streptococcus. The case is discussed during the obstetric staff every morning. If the cervix is unfavourable (cervical Bishop's score \<6), the information of the study is given to the patient and the consent collected. An antibiotic is started at the beginning of the inclusion by amoxicillin (or clindamycin in case of allergy of amoxicillin) to prevent choroamnionitis. After randomization, the patient is included in one of the two groups: Cook ® balloon or Propess ®. * In the Cook cervical ripening balloon group: the device is introduced by a resident or a doctor. No traction on the probe was done. It is left in place for maximum 12 hours. Oxytocin is added at the end of the first 6 hours even if device is fallen. An epidural analgesia can be started before or after the installation of oxytocin * In dinoprostone vaginal group: the device is placed in vaginal fornix by the midwife for maximum 24 hours. If Propess ® is fallen before the first 12 hours, another one could be introduce if the cervix stayed unfavourable. After 24 hours, it is removed. If they are any contraction, oxytocin is started with or without epidural analgesic. * The fetal heart rate is monitoring 30 minutes before and after the insertion of the device. After, the patient has a monitoring each 6 hours. * Since the oxytocin is started, the monitoring is registered in continue until the delivery.
Interventions
DRUGPropess® (dinoprostone)
The inclusion begins after 12 hours of PROM for a pregnant woman who has an unfavourable cervix and no B streptococcus. The case is discussed during the obstetric staff every morning. If the cervix is unfavourable (cervical Bishop's score \<6), the information of the study is given to the patient and the consent collected. An antibiotic is started at the beginning of the inclusion by amoxicillin (or clindamycin in case of allergy of amoxicillin) to prevent choroamnionitis.
DEVICEcook cervical pipening balloon
• In dinoprostone vaginal group: the device is placed in vaginal fornix by the midwife for maximum 24 hours. If Propess ® is fallen before the first 12 hours, another one could be introduce if the cervix stayed unfavourable.
