[Cesarean section in placenta previa].

51 cases of placenta previa among 12184 deliveries in our hospital from 1983,1,1 to 1989,2,28 were analyzed. During this period, we used conservative aggressive management to treat placenta previa. The perinatal mortality rate was 60%. Among the 51 cases, 50 were nullipara, 48 were terminated by cesarean section. The average blood loss during the operation was 743.6 ml, which was significantly higher than the average blood loss during the operation of general cesarean section. The various methods to control blood loss are discussed. The 8 figure suture could most effectively control blood loss at the placenta site. 4 patients underwent emergency cesarean hysterectomy.
