Extra corporeal membrane oxygenation therapy in acute respiratory distress syndrome due to Coronavirus-2019 (COVID-19): a retrospective study

Abstract

Aims: Extra corporeal membrane oxygenation (ECMO) has been used as a supportive treatment in ARDS due to COVID-19. Although different results have been reported in the literature regarding its efficacy, ECMO is recommended as a salvage therapy for severe forms of the disease after standard therapy fails. In our study,we aimed to evaluate the survival outcomes of patients supported with ECMO for COVID-19.
 Methods: Our study was conducted by scanning the data of consecutive adult patients hospitalized in our intensive care unit due to COVID-19. The ECMO process was planned according to the Extracorporeal Life Support Organization (ELSO) and Berlin criteria.
 Results: 51 patients hospitalized for acute respiratory failure due to COVID-19 were taken to ECMO. Demographic data of patients; 39 (76.5%) men and 12 (23.5%) women. 46 (90.2%) of the patients died. The mean intubation time before ECMO is 3.9 days, and the mean time for non-invasive mechanical ventilation is 5.8 days. The mean PaO2 value before ECMO was79.09 mmHg, the mean PCO2 value was 63.62 mmHg and the mean PaO2/FiO2 ratio was 82.80.
 Conclusion: The use of ECMO by considering prognostic factors and guidelines is seen as factors that increase the chance of success.Despite the fact that the patients were admitted to ECMO in accordance with the guidelines in our study, the high mortality rate suggests that there is a need for investigation of other supportive treatments and studies to reduce ECMO complications.
