The management principles of placental abruption are early recognition, active treatment of shock, timely termination of pregnancy, control of disseminated intravascular coagulation, and reduction of complications. 1. Early identification: Placental abruption is very harmful and the disease develops rapidly, if not handled in time, it can endanger the life of mother and child. Therefore, placental abruption should be recognized at an early stage and treated as soon as possible. 2. Active treatment of shock: for pregnant women with hemorrhagic shock, it is necessary to quickly establish intravenous access, active blood transfusion, rapid replenishment of blood volume and coagulation factors, to maintain the stability of the systemic blood circulation system. 3. Prompt termination of pregnancy: If there is intrauterine distress, fetal death, or maternal shock symptoms, the pregnancy should be terminated promptly. 4. Control disseminated intravascular coagulation: actively control bleeding, correct coagulation dysfunction as soon as possible, and reduce maternal mortality. 5. Reduce complications: Placental abruption may lead to serious complications for the fetus and the pregnant woman, such as intrauterine distress, hemorrhagic shock, amniotic fluid embolism, etc., which need to be actively treated to avoid complications. Clinical symptoms such as vaginal bleeding and abdominal pain in the middle and late stages of pregnancy require timely medical examination to rule out the possibility of placental abruption.
