Comparison of efficacy and safety of the Dinoprostone Vaginal tape and Dinoprostone vaginal tablet for the induction of labor in para three and more women: A retrospective cohort Study

Abstract

Background: Prostaglandins have a central role in the cervical ripening and parturition, and have been widely used for induction of labor (IOL). This study aimed to compare the effectiveness and safety of Dinoprostone vaginal tape (Propess) over Dinoprostone vaginal tablets (Prostin) for IOL and find which has better outcome to be applied in clinical practice. Participants and Methods: A retrospective cohort study was conducted via reviewing of medical records of multipara women admitted to King Fahad Medical City, Riyadh between January-2021 and December-2022 for IOL by Propess or Prostin. Results: A total of 87 multipara women were included in the study; 39 (44.8%) were treated by Propess and 48 (55.2%) were treated by Prostin for IOL. Full dilatation of the cervix after induction of labour was reported among majority of women (94.2%): being 92.1% among women treated with Propess and 95.8% among those treated with Prostin, however, this difference was not statistically significant, p>0.05. Regarding mode of delivery, normal spontaneous vaginal delivery was reported among 84.9% of women; 86.8% among women treated with Propess and 83.3% among those treated with Prostin while emergency cesarean section delivery was reported among 10.5% of women; 7.9% among women treated with Propess and 12.5% among those treated with Prostin. However, these differences were not statistically significant, p>0.05. Conclusion: The success rate of IOL among multipara women was high; however, no difference was reported between Propess and Prostin as regards the effectiveness (maximum cervical dilatation) and safety (rate of emergency cesarean section).
