title: Extracorporeal membrane oxygenation for newborn respiratory failure.
abstract: Respiratory failure is the leading cause of death in the newborn. Conventional therapy is very successful with 80% of infants weaned from ventilatory support. For neonates with severe respiratory failure, unresponsive to maximal medical therapy, extracorporeal membrane oxygenation (ECMO) offers an alternative means of management. Venoarterial bypass is achieved by cannulating the right atrium via the internal jugular vein and the aortic arch via the right common carotid artery. A 5-inch roller pump is used to circulate the blood through a 0.4 or 0.8 m2 silicone membrane lung. Management includes heparinization, intravenous alimentation, antibiotic coverage, and reduction of FiO2 and airway pressure. Thirty infants aged 12 to 186 hours were placed on ECMO. Each met strict criteria designed to predict greater than 90% mortality. Time on bypass ranged from 37 to 250 hours. Success, defined by weaning from ECMO and ventilatory support, was achieved in 23. Twenty-one remain alive; 18 have excellent outcome with normal growth and development although follow-up is short (1 to 19 mos). These results corroborate reports from the pioneers of the technique and further support the use of ECMO for neonates with respiratory failure unresponsive to conventional therapy.
