Use of blood transfusion in management of anemia.
Transfusion of red blood cells is useful in restoring oxygen-carrying capacity in patients with symptomatic anemia. In general, physicians should avoid transfusing blood based on hemoglobin concentration alone. Instead, they should focus on the impact of anemia on the patient's symptoms and level of activity. The concern for HIV infection and viral hepatitis has only served to highlight the potential risks associated with homologous transfusion therapy. These concerns should be carefully considered, along with possible alternatives, before a decision is made to transfuse. It is important to define the cause of anemia and to institute appropriate corrective therapy. The availability of recombinant human erythropoietin offers an option in selected patients to reduce or eliminate the need for red blood cell transfusion.
