Observational Study
Predictors of red blood cell transfusion and its association with prognosis in patients undergoing extracorporeal membrane oxygenation.
Few data are available on the potential benefits and risks of red blood cell transfusion in patients undergoing extracorporeal membrane oxygenation. The aim of this study was to identify the determinants and prognosis of red blood cell transfusion in patients undergoing extracorporeal membrane oxygenation, with a special focus on biological parameters during extracorporeal membrane oxygenation treatment. ⋯ This study suggests that red blood cell transfusion may be associated with a higher mortality rate and with severe complications. However, we cannot conclude a direct causal relationship, as red blood cell transfusion may be only a marker of poor outcome. We recommend that physicians correct acidosis and hemolysis in patients undergoing extracorporeal membrane oxygenation whenever possible.
