Prospective comparison of cervical ripening with double balloon Cook catheter, misoprostol or dinoprostone in term singleton pregnancies

Objectives: Induction of labor is indicated if the risk of continuing pregnancy is higher (either for fetus or mother) than the risk associated with the induction itself. The purpose of the present study was to compare the effectiveness of the double balloon Cook catheter and pharmacological preparations - prostaglandins (PGE), in our case it was misoprostol (PGE1) or dinoprostone (PGE2) for cervical ripening in pregnant women with gestational age at term.Material and methods: The prospective observational study was conducted from March 2017 to December 2018. We used mechanical and pharmacological methods for cervical ripening. We compared the efficiency of methods and time to delivery from start of cervical ripening. We also evaluated the neonatal complications by Apgar score and neonatal intensive care unit admission in three different groups.Results:Two hundred and nine women were chosen for cervical ripening. Double balloon Cook catheter and misoprostol were equally efficient in achieving vaginal delivery (76%). The shortest time for cervical ripening and successful vaginal delivery was shown in misoprostol (PGE1) group. In conclusion, no significant differences were found between groups in all neonatal outcomes.Conclusions: Currently, many methods of delivery preinduction exist and the prevalence of their usage varies considerably between countries. As yet, there is no literature comparing these three methods for the preparation of cervix.
