Abstract:

Amniotic fluid embolism is a rare and serious pregnancy complication and is an important cause of maternal death .Up to now，amniotic fluid embolism still lacks a clear and unified diagnostic standard，and it is only an exclusion diagnosis based on the clinical manifestations such as pulmonary hypertension，hypoxemia，hypotension，and coagulation dysfunction before massive hemorrhage that cannot be explained during labor and within 30 minutes after delivery.It is not recommended that any laboratory diagnosis be used for the diagnosis or exclusion of AFE，but blood routine，coagulation function，blood gas analysis，electrocardiogram，myocardial enzyme spectrum，chest X-ray，echocardiography，thromboelastic diagram，and hemodynamic monitoring are helpful for the diagnosis，condition monitoring and treatment of amniotic fluid embolism.Early treatment can improve the prognosis，so for every case of sudden pulmonary hypertension，hypoxemia，hypotension，coagulation dysfunction and other maternal symptoms，the possibility of amniotic fluid embolism should be considered.For clinically highly suspected amniotic fluid embolism，treatment can be performed before a definite diagnosis.
