Clinical analysis of the regimens for terminating the second-trimester pregnancy in cesarean section women.

To explore the suitable regimens of induced termination of second-trimester pregnancy in women with prior cesareans. A total of 204 s-trimester pregnant women with prior cesareans at the Third Affiliated Hospital of Zhengzhou University from January 2019 to December 2020 were included in this retrospective study. Group A included pregnant women who were administered mifepristone with misoprostol, Group B included those administering mifepristone with misoprostol as well as a transcervical Cook double-balloon catheter, Group C included those receiving mifepristone with an intra-amniotic injection of ethacridine lactate, and Group D included those receiving mifepristone, transcervical Cook double-balloon catheter, and intra-amniotic injection of ethacridine lactate. Their characteristics, clinical outcomes, and complications among the four groups were compared. All women had similar profiles in maternal age, gravidity, and previous cesarean delivery (p >.05). There was no significant difference in successful abortion among the four groups (p >.05). Group C had a significantly shorter induction-to-abortion interval than Group D (p <.01). The blood loss after abortion at 2 h in Group B was much less than Group A (p <.05). It made a significant difference between Group B and Group D regarding the blood loss after abortion at 2 h (p <.01). With regard to total incidences of adverse reactions, there were much fewer in the group B than the group A (p <.05). The four regimens are all effective for the termination of second-trimester pregnancy in women with prior cesareans. The use of transcervical Cook double-balloon could reduce the risks caused by misoprostol, and the combination of these is feasible to induce second-trimester pregnancy termination in women with prior cesareans.
