To the Editor.—  Because of the previous letters (240-2432, 1978;240:110, 1978) and article (239:729, 1978) in The Journal, as well as current reviews,1,2 the Blood Bank of the University of Arkansas for Medical Sciences has reviewed its experience with delayed hemolytic transfusion reactions. From July 1, 1978, through June 30, 1979, the Blood Bank transfused 5,292 units of RBCs containing products, 2,050 units of platelets, 1,132 units of fresh-frozen plasma, and 166 units of cryoprecipitate. During the same time in this tertiary care institution, 44 transfusion reactions were reported. One half of these were of the febrile type (ie, fever, chills, or both), while nine were urticarial, and five combined features of both aforementioned types. In addition, one anaphylactic reaction, four subsequently shown to be unrelated, and transfusional hemotherapy occurred. While no immediate hemolytic transfusion reactions were reported, three delayed hemolytic reactions were noted.
