RESUMO
Extracorporeal membrane oxygenation(ECMO)is an important cardiopulmonary support technique.It is the ultimate treatment for heart failure and lung failure after conventional treatment.ECMO enables the body to temporarily replace the pulmonary function and part of the heart function by extracorpore-al gas exchange,and creates a time window for the recovery of respiratory or cardiac function. In 1974, ECMO was first used in neonates.There are many complications in the application of ECMO in neonates, including mechanical complications,bleeding and thrombosis,hemolysis,neurological complications,renal dysfunction,gastrointestinal complications,infection,etc.Long term follow-up found that growth and develop-ment are affected by varying degrees. Timely monitoring,identification of complications and appropriate treatment will improve outcomes.
