In the case of bleeding caused by placental abruption, the main thing is usually not to treat the bleeding, but more importantly, if there is shock, it is necessary to correct the state of shock in time and terminate the pregnancy in time to prevent serious consequences. Placental abruption refers to the partial or total detachment of the normally positioned placenta from the uterine wall after 20 weeks of gestation or during labor and delivery of the fetus. It is often characterized by vaginal bleeding, abdominal pain and other symptoms. Placental abruption is a serious complication in late pregnancy, which can jeopardize the life of both mother and child if not treated in time. Therefore, if the diagnosis of placenta previa is confirmed, it is necessary to terminate the pregnancy in time. If the patient bleeds a lot and suffers from shock, it is necessary to correct the shock first and then terminate the pregnancy. The method of termination of pregnancy depends on the number of fetuses, the severity of placental abruption, the intrauterine condition of the fetus and the opening of the uterus. Therefore, vaginal bleeding during pregnancy requires prompt medical attention to avoid delays.
