Abstract

Factors that predict outcome after ABO-incompatible RBC transfusions are not well defined. We studied whether the volume of incompatible blood transfused would determine the signs and symptoms and survival outcome for ABO-incompatible RBC transfusions. We reviewed ABO-incompatible RBC transfusions from our institutions and our consultations for 35 years and from a survey of America's Blood Centers'members regarding causes, volume, signs, symptoms, and outcomes of ABO-incompatible RBC transfusions in their service areas from 1995 through 2005. All ABO-incompatible transfusions were due to error; 26 (62%) of 42 occurred at the patient's bedside. Of 36 patients who received more than 50 mL of incompatible blood, 23 (64%) manifested signs or symptoms related to the incompatible transfusion, and 6 (17)% died. Only 3 (25%) of 12 patients who received 50 mL or less of incompatible blood had associated signs or symptoms, and none died. Hypotension, hemoglobinuria, and/or hemoglobinemia were the most frequent findings in survivors and patients who died. ABO-incompatible RBC transfusion does not inevitably mean death or even occurrence of symptoms. Prompt recognition and discontinuation of the transfusion are critical because transfusing less ABO-incompatible blood may minimize signs and symptoms and may prevent death.
