Extracorporeal membrane oxygenation for respiratory failure in the elderly: a review of the Extracorporeal Life Support Organization registry.
Extracorporeal membrane oxygenation (ECMO) support among adults is increasing; however, the role in respiratory failure in the elderly is not clearly defined. The aim of the current study is to investigate survival to hospital discharge among the elderly supported on ECMO. The Extracorporeal Life Support Organization registry database was queried, identifying all elderly patients (≥65 years of age) supported on ECMO for respiratory failure from 1990 to May 2013. The primary outcome was survival to hospital discharge. Clinical characteristics between survivors and nonsurvivors were compared. A total of 368 elderly patients treated with ECMO support for respiratory failure were identified. The median admit-to-initiation-of-ECMO time was 24.5 hours, and median duration of ECMO was 140 hours. Survival at hospital discharge was 41%. Approximately 69% of the overall ECMO usages occurred from 2010 to 2013. Nonsurvivors had significantly higher pre-ECMO peak inspiratory pressures, lower SaO2/FiO2 ratio, and higher rate of diverse complications. Among pre-ECMO therapies, vasodilators, steroids, and inhaled nitric oxide were more frequently used in survivors. Survival-to-hospital discharge rate is lower (41%) in elderly patients treated with ECMO compared with that in all adults (55%). However, given the noted survival, age should not be a firm contraindication for the use of ECMO in older patients but should be considered on a case-by-case basis.
