Placental abruption is a serious complication of late pregnancy that develops rapidly and can endanger the life of the mother and child if not treated in time. Placental abruption has serious consequences for both the mother and the child, increasing the incidence of cesarean section, anemia, postpartum hemorrhage, and disseminated intravascular coagulation, and in severe cases, death may result from blood loss. Acute hemorrhage from placental abruption can also lead to fetal hypoxia, increasing the chances of neonatal asphyxia, preterm labor, and intrauterine fetal death. Even if the fetus is born, the newborn is prone to significant neurological developmental defects and other sequelae due to intrauterine hypoxia, causing serious harm to the newborn and the family. Once placental abruption is detected in the clinic, timely medical treatment is needed to minimize the occurrence of adverse pregnancy outcomes.
