Transfusion Requirements in Cardiac Surgery

"Patients allocated to a liberal transfusion strategy will receive red cell transfusion if their hemoglobin concentration is 95 g/L or less intraoperatively and postoperatively in the intensive care unit, and less than 85 g/L on the ward."

"Patients allocated to a restrictive transfusion group will receive a red cell transfusion if their hemoglobin is 75 g/L or less intraoperatively and postoperatively."
