Massive hemorrhage due to hemodialysis-associated thrombocytopenia

Abstract

Marked declines in platelet numbers were noted in association with hemodialysis. This resulted in gastrointestinal bleeding and the need for packed RBC and platelet transfusions. This hemodialysis-associated thrombocytopenia was ameliorated by changing the dialyzer in use. The gastrointestinal bleeding stopped and the need for platelet transfusions was obviated. The degree of platelet loss during hemodialysis is probably affected by the composition of the dialyzer membrane used as well as other factors. Hemodialysis-associated thrombocytopenia may be a contributing factor in the increased bleeding tendency noted in hemodialysis patients.
