268PATIENT BLOOD MANAGEMENT IN OCTOGENARIANS: PREDICTORS OF TRANSFUSION AND PROGNOSTIC IMPLICATIONS

Objectives: Red blood cell (RBC) transfusion is a well-known predictor of acute kidney injury (AKI) and death after cardiac surgery procedures. This study explored whether a similar effect existed among octogenarians. Methods: The study population included 1765 consecutive adult patients undergoing cardiac operations on cardiopulmonary bypass from 2011 to 2013 in a single centre (age: 67.6 ± 10.3 years; octogenarians: 178; female: 33.1%; redo: 6.2%; urgent/emergent: 12.9%; isolated CABG: 40.1%; isolated valve procedures: 30.4%; combined: 26.7%). The relationship between RBCs with both survival and AKI, and any interaction by age (
