Heparin Treatment of Intravascular Coagulation Accompanying Hemolytic Transfusion Reactions

Abstract
Two patients with disseminated intravascular coagulation secondary to incompatible blood transfusion are reported. In one, the antibody responsible for the incompatibility was a noncomplement‐dependent anti‐Fya. Intravascular coagulation may be more frequent than has been appreciated, hence, laboratory study of hemostasis should be a part of the evaluation of patients who have received incompatible blood. Prompt diagnosis along with heparin therapy may prevent the development of a generalized bleeding diathesis.
