A potentially disastrous complication involving cardiopulmonary collapse in a pregnant woman is amniotic fluid embolism (AFE), also known as anaphylactoid syndrome of pregnancy (ASP). ASP, or AFE, is rare. Most studies indicate that the incidence rate is between 1 and 12 cases per 100,000 deliveries. The maternal mortality rate from AFE has been reported to be anywhere from 10% to 90%, although more recent data from large unselected populations suggest that overall mortality rates may be closer to 20%. Those who survive generally have a poor outcome, with as many as 85% suffering significant neurologic injury from cerebral hypoxia. It is one of the leading causes of maternal mortality.
