Abstract Objective To explore the risk factors of postpartum hemorrhage in elderly women with second cesarean section. Methods The clinical data of 480 elderly women who underwent second cesarean section in the Fourth People′s Hospital of Shenyang from January 2017 to April 2019 were analyzed retrospectively. According to whether there was postpartum hemorrhage, they were divided into hemorrhage group (60 cases) and non-hemorrhage group (420 cases). The general situation, medical history and pregnancy process of the two groups were compared, and the high risk factors of postpartum hemorrhage of the elderly women in the second cesarean section were analyzed by logistic regression analysis. Results There were significant differences in abortion, fetal position, macrosomia, placenta previa, placental implantation and placental attachment between two groups (P ＜ 0.05). There were no significant differences between two groups in parturient times, induced labor, gestational hypertension and gestational diabetes (P ＞ 0.05). Multiple logistic regression analysis showed that the placental attachment position [OR = 3.611, 95%CI (1.471-8.864), P = 0.005], placenta previa [OR = 5.214, 95%CI(2.456-11.069), P ＜ 0.001] and placental implantation [OR = 15.213, 95%CI(7.245-31.941), P = 0.001] were the high risk factors of postpartum hemorrhage in elderly women with second cesarean section. Conclusion The postpartum hemorrhage of the elderly women in the second cesarean section should not be ignored. The elderly women in the second cesarean section with placenta previa, placenta implantation and placental attachment position are more likely to have postpartum hemorrhage. Therefore, the positive preventive measures should be taken in clinical practice.
