This article reviews appropriate platelet support of those patients who are chronically thrombocytopenic because of decreased platelet production, including those receiving chemotherapy or radiation treatments and those undergoing bone marrow transplants. The platelet products available for transfusion and the indications for platelet transfusions are discussed. Expected responses to platelet transfusions are reviewed as well as the prevention of platelet alloimmunization. Finally, a discussion of the mechanisms and management of platelet refractoriness is included.
