Abstract Background This study aims to evaluate the efficacy and safety of induction labour in mid-trimester pregnancy using a double-balloon catheter (DBC) within 12 h versus 12–24 h. Methods In this retrospective study, total 58 pregnant women at 14 + 0 weeks 27 6 gestation were enrolled as research subjects, they underwent intended termination our birth centre from January 1, 2017, June 31, 2019. Based on duration DBC, patients divided into two groups, namely, DBC group Results All cases successful vaginal deliveries, no one chose undergo caesarean section. The success rate (successful abortion foetus placenta without implementation dilation evacuation) was higher (96.3%, 29/31) than (71.0%, 18/27) ( p < 0.05). Additionally, time removal delivery significantly shorter that (3.0 17.8 h) 0.05), degree cervical after larger Conclusion clinic, placement generally lasts for approximately However, considering condition is immature mid-trimester, properly extending 24 will benefit ripening reduce chance evacuation.
