Abstract
Transfusion guidelines in patients with coexisting cardiac diseases are similar to the ones in patients without such comorbidity, in that allogeneic blood transfusions most often are indicated at hemoglobin levels of less than 6.0 g/dL and hardly ever at hemoglobin levels greater than 10 g/dL. In the hemoglobin range of 6 to 10 g/dL, signs of impaired oxygenation should serve as transfusion indications, and such signs may be reached at higher hemoglobin values than in healthy patients. An inadequate oxygenation may become manifest globally in the form of a general hemodynamic instability with a tendency to hypotension and tachycardia despite normovolemia or an oxygen extraction of greater than 50%. An inadequate oxygenation in the form of myocardial ischemia may be manifested by new ST-segment depressions of greater than 0.1 mV, new ST-segment elevations greater than 0.2 mV, or new wall motion abnormalities in transesophageal echocardiography. Institutional guidelines also should consider local logistic characteristics such as the level of knowledge of physician and nurse staff caring for patients and the level of surveillance possible justifying eventually higher hemoglobin transfusion triggers, particularly in the postoperative period.
