General
=========================================================================

● Hemolysis of pRBCs from non-immune causes, such as storage or inappropriate handling of blood products (microwave, using small needle for transfusion, transfusion of pRBCs with Lactated Ringer solution, use of hyper- or hypoosmotic fluids, thermal injury, etc.)
● ALWAYS need to rule out immune causes of hemolysis
● Lysed red cells may cause hemodynamic, renal and pulmonary problems, possibly death

Laboratory
=========================================================================

● Hemoglobinemia, hemoglobinuria, possibly hyperkalemia (if renal failure)

Clinical features
=========================================================================

● Clinical features and treatment are similar to acute hemolytic transfusion reaction
● Stop transfusion and maintain IV access
● Contact transfusion service to rule out immune cause of hemolysis
● Monitor urine output
● Should also consider possibility of transfusion related infection (malaria, babesiosis)

Case reports
=========================================================================

● Percutaneous mechanical thrombectomy (Transfusion 2005;45:1291)
