Objective To explore the relevant risk factors of postpartum hemorrhage(PPH)after vaginal trial delivery failure and conversion to cesarean section.Methods Clinical data of 362 women who underwent vaginal trial delivery failure and underwent cesarean section at Hangzhou Obstetrics and Gynecology Hospital from January 2022 to March 2023 were collected.They were divided into thev PPH group(n=40)and the non PPH group(n=322)based on the occurrence of PPH.Risk factors for PPH were screened using univariate and multivariate logistic regression models.Results The age,preoperative uterine opening,trial delivery time,soft birth canal edema,placental adhesions,uterine incision tears,macrosomia,and other aspects of postpartum women in the PPH group were significantly higher than those in the non PPH group(P<0.05),while preoperative hemoglobin levels,fibrinogen(FIB)levels,and labor analgesia were significantly lower than those in the non PPH group(P<0.05).Logistic regression analysis showed that prenatal FIB≤3 g/L,trial delivery time≥18 hours,soft birth canal edema,uterine incision tear,and delivery macrosomia were risk factors for PPH(P<0.05),and delivery analgesia was a protective factor for postpartum PPH(P<0.05).Conclusion The failure of vaginal trial delivery and the conversion to cesarean section are mainly related to factors such as prolonged trial delivery time,soft birth canal edema,uterine incision tear,delivery macrosomia,and reduced FIB.Scientific use of labor analgesia can improve the delivery experience of postpartum women and reduce the risk of postpartum hemorrhage.
