Aims/ObjectivesThe aims of this study were to report a patient with acute haemolytic transfusion reaction (HTR) after transfusing uncross-matched red blood cell (RBC) units and to identify the frequency of this complication.
BackgroundUncross-matched RBC units are commonly transfused in emergencies, but the frequency of acute HTR is unknown.
MethodsWe describe a male stabbing victim who received three units of uncross-matched RBC units complicated by acute intravascular HTR, disseminated intravascular coagulation (DIC) and renal failure. We identified 14 studies evaluating the frequency of acute HTR post-emergency transfusion of uncross-matched RBC units.
ResultsAcute HTR was shown by haemoglobinuria, free-plasma haemoglobin and methemalbumin, with anti-K and anti-Fy(a) eluted from recipient red cells; acute DIC featured severe hypofibrinogenemia, thrombocytopenia, elevated fibrin D-dimer and multiple bilateral renal infarcts. Two of the three transfused units reacted with pre-existing RBC alloantibodies [anti-K (titre, 128), anti-Fy(a) (titre, 512)], explained by transfusion 25years earlier. Our literature review found the frequency of acute HTR following emergency transfusion of uncross-matched RBC units to be 2/3998 [006% (95% CI, 001-021%)].
ConclusionsAlthough emergency transfusion of uncross-matched blood is commonly practiced at trauma centres worldwide, with low risk of acute HTR (<1/1000), our well-documented patient case demonstrates the potential for acute HTR with severe complications.
