Study Arms (2)
Restrictive transfusion strategy
ACTIVE COMPARATORRestrictive transfusion strategy: patients will receive a red cell transfusion if their hemoglobin is \<75 g/L (\<7.5 g/dL;\<4.7mmol/L) intraoperatively and/or postoperatively
Liberal transfusion strategy
ACTIVE COMPARATORLiberal transfusion strategy: patients will receive a red cell transfusion if their hemoglobin concentration is \<95 g/L (\<9.5 g/dL\<5.9mmol/L) intraoperatively, or postoperatively in the intensive care unit; and/or \<85 g/L (\< 8.5 g/dL;\<5.3mmol/L) on the ward.
