Abstract
Background: The World Health Organization recommends extracorporeal membrane oxygenation (ECMO) as a therapeutic option for the most critical cases of severe coronavirus disease 2019 (COVID-19). However, data on universally agreed-upon risk factors that contribute to ECMO weaning failure and mortality in COVID-19 patients undergoing ECMO are limited. This lack of consensus leads to significant uncertainties in developing effective management strategies for these patients. We aimed to identify the factors associated with early outcomes after ECMO support in patients with COVID-19-induced acute respiratory distress syndrome, specifically the success rate of ECMO weaning and in-hospital mortality. Methods: We reviewed 25 patients with COVID-19 who received ECMO support at a single institution between January 2020 and July 2022. This retrospective data collection and review included clinical characteristics, adjunctive treatments, complications, and early patient outcomes. Results: A total of 72% of the patients were successfully weaned off ECMO, and 68% were discharged alive. Significant associations were observed between ECMO weaning success and in-hospital survival, particularly younger age and a history of rehabilitation therapy. Furthermore, the absence of a history of immunosuppressive therapy contributed significantly to successful ECMO weaning. Conclusions: Younger age and the implementation of rehabilitation therapy are associated with improved outcomes in patients with COVID-19 receiving ECMO support.
