Definition / general
- Hemolysis of pRBCs from nonimmune 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 hypo-osmotic 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
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)
Laboratory
- Hemoglobinemia, hemoglobinuria, possibly hyperkalemia (if renal failure)
Case reports
- Percutaneous mechanical thrombectomy (Transfusion 2005;45:1291)
