Treatment of central placenta previa with massive hemorrhage

once the central placenta previa is found to need cesarean section to terminate pregnancy, no matter how many months of pregnancy, blood should be prepared during the operation, and the patient's family should be informed that there is a possibility of hysterectomy. Patients with massive bleeding should open the venous channel as soon as possible for blood transfusion to supplement blood volume, and at the same time use hemostatic drugs to stop bleeding.
