Cesarean section history, intrauterine operation history and multiple pregnancies were independent risk factors of placenta previa (P <0.05). The rate of postpartum hemorrhage in the placenta previa was higher than that in the non-placenta previa (P <0.05). The incidence of postpartum hemorrhage, fetal distress and neonatal asphyxia in the placenta previa at 36 weeks’ 36 weeks of placenta previa; postpartum hemorrhage maternal oxytocin, Yan Xin Pei, uterine artery ligation and bilateral ligation of bilateral artery embolization, 3 cases of hysterectomy to stop bleeding.
