Double balloon catheter for labour induction at term after previous cesarean: a retrospective clinical research

Abstract

Objective To determine the safety and effectiveness of double balloon catheter for labor induction in women with previous cesarean section. Methods This was a retrospective case-control study. Data from Shenzhen maternal and child healthcare hospital and Shenzhen Longgang District Maternal and Child Healthcare Hospital between 2015.01.01 to 2018.12.31 were used. A total of 156 term pregnant women, with previous one low segment cesarean section (CS) and balloon catheter for labour induction were included as case group. A total of 156 term pregnant women with previous one low segment CS and spontaneous onset of labor were included as control group. The vaginal delivery rate and maternal and infant outcomes were compared between the two groups. Results There was no significant difference in CS rate, vaginal assisted rate and vaginal spontaneous rate between the two groups (20.51% vs 15.38%, 8.97% vs 5.77%, 70.51% vs 78.85% respectively, P>0.05). And there were no significant difference in the rates of intrauterine infection, uterine rupture, postpartum hemorrhage, blood transfusion, maternal and infant mortality and neonatal transfer between the two groups. Conclusions Our study indicates that induction of labor with double balloon catheter is effective and safe in term pregnant women with previous one low segment CS. Women with previous CS and indications for labour induction should be informed about vaginal birth success rates and the alternative of elective repeat CS needs to be discussed.
