Abstract Objective To analyze the risk factors of postpartum hemorrhage in women of advanced maternal age by using retrospective study methods and to discuss the intervention measures to prevent and reduce postpartum hemorrhage in order to provide reference for the prevention and treatment of postpartum hemorrhage in the women of advanced maternal age.Methods Altogether 47 women of advanced maternal age who underwent delivery and postpartum hemorrhage in our hospital from January 2016 to October 2017 were selected as the observation group;while,another 47 cases of women of advanced maternal age who underwent delivery without postpartum hemorrhage in our hospital during the same period were selected as the control group.The clinical data of two groups of patients were summarized and analyzed,and the risk factors related to postpartum hemorrhage were determined by using single factor and multiple factor Logistic regression analysis.Results There was no statistically significant difference in the general data of age,body mass index and gestational weeks between the two groups (P＞0.05).There was no statistically significant difference in the general data of smoking history,drinking history and family medical history between two groups(P＞0.05).It was shown according to the data that factors,such as multiple pregnancy,gestational hypertension(GH),placenta praevia,placental abruption,placental adhesion/implantation/residue,uterine inertia,macrosomia,laceration of birth canal and coagulation dysfunction,were associated with postpartum hemorrhage(P<0.05);factors such as gestational diabetes and multiple pregnancy were not significantly associated with postpartum hemorrhage(P＞0.05).According to the multiple factor Logistic regression analysis,it indicated that postpartum hemorrhage was the result of multiple factors.The significant risk factors related to postpartum hemorrhage were multiple pregnancy,gestational hypertension,placenta praevia,placental abruption,placental adhesion/implantation/residue,uterine inertia and macrosomia.Conclusion Multiple pregnancy,gestational hypertension,placenta praevia,placental abruption,placental adhesion/implantation/residue,uterine inertia and macrosomia are significant risk factors for postpartum hemorrhage.Doctors and pregnant women should pay attention to preoperative diagnosis,prevention and post-operative treatment of high-risk factors so as to reduce the rate of postpartum hemorrhage.
