Extracorporeal membrane oxygenation (ECMO) support for acute hypoxemic respiratory failure patients: outcomes and predictive factors.

Extracorporeal membrane oxygenation (ECMO) is an important rescue therapy for patients with refractory respiratory or circulatory failure. High cost and associated complications warrant careful case selection. The aim of this study was to investigate the outcomes and factors associated with mortality in acute hypoxemic respiratory failure patients who received ECMO support, and to externally validate preexisting ECMO survival prediction scoring systems. This retrospective study enrolled acute hypoxemic respiratory failure patients who received veno-venous (VV) or veno-arterial (VA) ECMO support at Siriraj Hospital (Bangkok, Thailand) from 2010 to 2020. All relevant baseline patient characteristics including ECMO survival prediction scores were recorded. The primary outcome was in-hospital mortality. Multivariate logistic regression analysis was employed to identify independent predictors of in-hospital mortality. Of a total of 65 patients, 34 (52%) were male, the median (IQR) age was 61 years (49-70 years), the median body mass index (BMI) was 22.6 kg/m In-hospital mortality among ECMO-supported patients was high at 69%. SOFA score >14, hospitalized >72 hours, PaO www.clinicaltrials.gov (reg. No. NCT04031794).
