High-risk factors for massive hemorrhage during induced abortion for unplanned pregnancy after cesarean section

Abstract:

Objective To investigate the high-risk factors for massive hemorrhage during induced abortion for unplanned pregnancy after cesarean section.Methods A prospective cohort study was conducted for the clinical information and imaging data of 228 patients with unplanned pregnancy after caesarean section who underwent induced abortion at the outpatient service of Department of Obstetrics and Gynecology in Chongqing General Hospital from January 2022 to April 2023. Univariate analysis and multivariate logistic regression analysis were used to investigate the risk factors for massive hemorrhage during induced abortion.Results Among the 228 patients，59 experienced massive intraoperative hemorrhage，accounting for 25.87%. The univariate analysis showed that number of births，number of cesarean sections，maximum gestational sac diameter，distance from the gestational sac to the uterine incision scar，cessation of embryonic development，and pregnancy time were risk factors for massive hemorrhage during induced abortion for unplanned pregnancy after cesarean section（P<0.05）. The multivariate logistic regression analysis showed that number of cesarean sections，maximum gestational sac diameter，distance from the gestational sac to the uterine incision scar，cessation of embryonic development，and pregnancy time were independent risk factors for massive hemorrhage during induced abortion for unplanned pregnancy after cesarean section（P<0.05）.Conclusion The risk of massive hemorrhage during induced abortion can be reduced by decreasing the rate of cesarean section and implementing efficient contraception after cesarean section.
