Abstract：Objective To explore the risk factors of severe postpartum hemorrhage in pregnant women undergoing vaginal delivery.Methods A retrospective analysis was conducted on the medical records of postpartum hemorrhage during vaginal delivery at Shijiazhuang Fourth Hospital from January 1,2018 to December 31,2022.Among them,238 cases of severe postpartum hemorrhage during vaginal delivery were selected as the study group.Pairing method was used for the study,and 221 matched cases of no-severe postpartum hemorrhage during vaginal delivery were selected as the control group.Statistical analysis was used to identify the risk factors for severe postpartum hemorrhage during vaginal delivery.Results In univariate analysis,the study group showed statistically significant differences in weight gain,newborn weight,place of residence,total duration of labor,gestational hypertension,midwifery status,and per delivery hemoglobin,PT,APTT compared to the control group.The logistic regression results showed that neonatal weight,total duration of labor,midwifery status,and pre delivery PT were all independent risk factors for severe postpartum hemorrhage.Conclusions The occurrence of severe postpartum hemorrhage during vaginal delivery is related to factors such as birth weight,total duration of labor,midwifery status,and pre delivery PT.Preventing and controling these factors can effectively prevent its occurrence.
