Extracorporeal life support and extracorporeal membrane oxygenation characterize the use of mechanical devices for temporary support of heart and lung function. The mechanical circuit consists of a blood pump (heart), membrane oxygenator (lung: which accomplishes both carbon dioxide removal and oxygen delivery), heat exchanger and a servo-control module. Venous blood is drained from the right atrium through the right internal jugular vein, and returned oxygenated through either the right common carotid artery (venoarterial bypass), or into a large vein (venovenous bypass). All patients treated must be free of coagulopathies, as all patients are anticoagulated. Neonatal candidates should be older than 34 weeks gestational age and weigh more than 2000 grams. As of March, 1997 twenty six patients have been treated with extracorporeal life support at Tulane Medical Center with an overall survival rate of 62%. Twelve neonates with either meconium aspiration or pneumonia have been treated with a 100% survival. Six children with congenital diaphragmatic hernia have been unsuccessfully treated.
