ECMO for neonatal respiratory failure.

Abstract

Extracorporeal membrane oxygenation (ECMO) has been offered as a life-saving technology to newborns with respiratory and cardiac failure refractory to maximal medical therapy. ECMO has been used in treatment of neonates with a variety of cardio-respiratory problems, including meconium aspiration syndrome (MAS), persistent pulmonary hypertension of the neonate (PPHN), congenital diaphragmatic hernia (CDH), sepsis/pneumonia, respiratory distress syndrome (RDS), air leak syndrome, and cardiac anomalies. For this group of high-risk neonates with an anticipated mortality rate of 80% to 85%, ECMO has an overall survival rate of 84%, with recent data showing nearly 100% survival in many diagnostic groups. This article reviews the current selection criteria for ECMO and the clinical management of neonates on ECMO, and discusses the long-term outcome of neonates treated with ECMO.

Extended use of extracorporeal membrane oxygenation after lung transplantation.

OBJECTIVES: Extracorporeal membrane oxygenation (ECMO) for severe graft failure after lung transplantation is accepted immediately postoperatively; extending its use is controversial. We evaluated our post-lung transplant ECMO experience, which included extended indication, to (1) determine its prevalence, risk factors, indications, and timing, (2) compare complications and outcomes of these patients with those not requiring it, and (3) identify risk factors, including indications, for mortality. METHODS: From February 1990 to October 2005, 474 patients underwent lung transplantation; postoperative ECMO support was instituted for severe graft failure 23 times in 22 patients (4.0%). Indications for ECMO and its timing were obtained by reviewing medical records and survival by systematic follow-up. RESULTS: No factor evaluated predicted severe graft failure leading to ECMO. The most common indication for ECMO was early graft failure (13 patients); however, it was also used for pneumonia or sepsis (6) and acute rejection (4). ECMO was initiated at a median arterial oxygen tension/inspired oxygen fraction of 59 at a median of 2 days postoperatively and was maintained for a median of 4 days. The most common complications were renal failure (57%) and bleeding (43%). ECMO was effective in salvaging patients with rejection and early graft failure (survival at 1, 3, 6, and 12 months: 62%, 54%, 49%, and 41%), but ineffective for pneumonia or sepsis (survival at these intervals: 9%, 4%, 4%, and 3%). CONCLUSIONS: ECMO can be extended beyond early severe graft failure to acute rejection and can be considered after the immediate postoperative period. Survival after ECMO in patients with pneumonia or sepsis is poor.
