bleeding
post-transfusion purpura
3-4 weeks after transfusion
rash fever diarrhea cytopenia liver dysfunction
transfusion graft vs host disease
dyspnea bilateral pulmonary edema hypotension fever tachycardia does not respond favorably to diuretics
transfusion related acute lung injury (TRALI)
within 6 hours
increasing respiratory distress tachycardia increased BP pulmonary edema evidence of fluid overload
transfusion associated circulatory overload (TACO)
fever but no hemolysis after a transfusion?
febrile non-hemolytic transfusion reaction
onset within 90 mins of transfusion
fever chills back pain chest pain tachycardia hypotension hemoglobinemia hemoglobinuria hyperbilirubenemia
acute hemolytic transfusion reaction
Equation to determine amt of blood need
(pt TBV *(desired Hct- pt Hct))/Hct of transfusion
when is direct Coombs used
to detect hemolysis from a transfusion reaction
When is indirect Coombs used
when screening before transfusion
