Comparison between Mechanical induced Cervical Dilatation in Previous Scar Woman in 2nd Trimaster Abortion Non-Randomized Controlled Study

Abstract

Background and objective: Mechanical strategies incorporate the insertion of a balloon catheter or placement of a hygroscopic dilator. Balloon catheters were utilized within the larger part of past trials comparing mechanical and pharmacologic strategies. The objectives of this study were to compare the efficacy and safety of hygroscopic dilators and balloon catheters for ripening of the cervix in induction of labor. Methods: This study was a single-canter, nonrandomized, open-label trial conducted on participants who had been non-randomly allocated to either Dilapan-S (DS) or Foley balloon (FB) groups. The present study was conducted on 200 women, who had been selected randomly from attendants of the obstetrics and gynecology department at the Minia Maternity University Hospital in the period between October, 1 st 2020 and September, 1 st 2021. Results: The percentage of success rate was higher among the Dilapan-S group, however; there was non-statistically significant difference between both trial arms, [65/74 (87.8%) vs. 100/124 (806%), p-value= 0.131], in Dilapan-S and Foley balloon groups respectively. Conclusion: Dilapan-S is safe, effective induction method at second trimester termination with outcome comparable to Foley's balloon catheter in the cervical preparation. Both Dilapan-S and Foley's catheter have equivalent efficacy, lower risk of hyperstimulation and no clear evidence of increased infection risk.
