Placental abruption may lead to cerebral palsy, and pregnant women need to take medication to preserve the fetus or surgical treatment to terminate the pregnancy, depending on the actual situation. Placental abruption is a condition that occurs after 20 weeks of pregnancy or during labor and delivery, in which part or even all of the placenta detaches from the uterine wall, which can have a serious impact on the health of the pregnant woman as well as the development of the fetus. The condition will prevent the fetus from absorbing nutrients from the mother’s body through the placenta, and some fetuses may also suffer from asphyxia and cerebral hypoxia, which is a common cause of cerebral palsy, so fetuses with placental abruption may become cerebral palsy. Pregnant women with placental abruption need to consult a doctor in time and choose the appropriate treatment according to their actual situation. Once placental abruption occurs, the pregnancy should be terminated as soon as possible after the diagnosis is confirmed, and according to the degree of placental abruption and the condition of the labor process of the pregnant woman, the pregnancy should be terminated in time through vaginal delivery or cesarean section surgery. It is recommended that pregnant women with placenta previa should seek medical treatment as soon as possible through the above mentioned ways to avoid delaying the condition and causing serious impact on their health.
