Bleeding from an anterior placenta often presents as unprovoked, painless, recurrent vaginal bleeding in late pregnancy. Once bleeding is present, a decision should be made based on the amount of bleeding, gestational week, maternal risk, maturity and size of the fetus, etc. If the bleeding is not heavy, the decision should be based on the gestational week. For small gestational week and immature fetus, the main treatment is symptomatic. Fetal preservation treatment such as hemostasis, contraction inhibitor and fetal lung maturation promotion can be given, and oral blood supplementation can also be taken to improve anemia and prolong the gestational week as much as possible. During the period of fetal preservation, eat more fresh vegetables and keep the bowel movement smooth. If the fetus is mature, the gestational week is large, it has reached full term or is close to full term, and it is considered that the fetus can survive after delivery, most of the pregnancies need to be terminated early by cesarean section. In case of heavy bleeding and shock, which endangers the life of the pregnant woman, regardless of the condition of the fetus, the pregnancy should be terminated promptly to stop the bleeding, and antibiotics should be applied to prevent infection if necessary.
