However, despite this reduction, AFE still accounts for 4.7% of direct maternal deaths in the UK, 13% in France, 30% in Singapore, and up to 10% in the USA and Australia. The majority of patients with AFE die within the first hour of onset of symptoms and about 85% of those who survive have permanent neurological impairment. Elements of presumed fetal origin were detected in 73% of those undergoing autopsy and in 50% of those in whom such evidence was sought during life by the examination of pulmonary artery catheter aspirate. Neonatal mortality is ∼70%. If the fetus is alive at the time of event, nearly 70% will survive delivery but 50% of the survived neonates will incur neurological damage.
