Liberal Transfusion Strategy
Restrictive Transfusion Strategy
Red blood cell transfusion - One unit of packed red cells is transfused following randomization followed by enough red blood cell units to raise the hemoglobin concentration above 10 g/dL any time the hemoglobin concentration is detected to be below 10g/dL during the hospitalization for up to 30 days.
Permitted to receive a red blood cell transfusion if the blood count is below 8 g/dL and the physician believes it is in the patient's best interest. A transfusion will be strongly recommended if the blood count drops to less than 7 g/dL. If the patient has symptoms of angina (e.g., chest discomfort described as pressure or heaviness) that do not go away with medication, a blood transfusion will be ordered regardless of the blood count.
