We report the case of a 6-year-old boy who began to have fever and hypotens
ion during the administration of a platelet transfusion. Subsequent investi
gation revealed the etiology to be bacterial contamination of the platelet
product. Serratia marcescens was cultured from both the patient's blood and
the platelet product. When fever and/or cardiorespiratory problems develop
during the administration of blood products, possible bacterial contaminat
ion of the product must be considered so that appropriate therapy can be in
stituted. We discuss the etiology, possible preventive strategies, and the
treatment of this problem.
