Amniotic fluid embolism may occur during cesarean section. It is recommended to choose a regular hospital for delivery, which can reduce certain risks. Amniotic fluid embolism refers to a series of pathophysiological changes caused by the entry of amniotic fluid into the maternal circulation, including pulmonary hypertension, circulatory failure, disseminated intravascular coagulation, organ failure and so on. During cesarean section, there are inevitably open blood vessels or blood sinuses, and after rupture of membranes, amniotic fluid may enter the maternal circulation and cause amniotic fluid embolism. Cervical lacerations, uterine rupture, excess amniotic fluid, multiple pregnancies, excessive uterine contractions, cesarean section and curettage may be triggers for the development of amniotic fluid embolism. The exact cause of its occurrence is unknown and may be related to factors such as high pressure in the amniotic cavity, rupture of fetal membranes, and opening of blood sinuses. Amniotic fluid embolism is unpredictable and can occur during both normal labor and cesarean section. Amniotic fluid embolism is extremely aggressive and treatment is mainly supportive and symptomatic, requiring a variety of means at the same time. It is recommended to have the birth in a regular hospital in order to receive prompt treatment in the event of an accident.
