Q: In OR "Cell Saver" technique  (intraoperative autologous transfusion or intraoperative autotransfusion)  is frequently used. Why it is important to wash the blood before infusion back into patient?

Answer: Blood from patient needs to be 
  • processed/collected in a sterile, filtered reservoir, 
  • centrifuged, which separates and concentrates higher density RBCs 
  • washed – with an isotonic solution, and
  • reinfused

Salvaged blood should be washed. Unwashed salvaged blood has residual anticoagulant, dysfunctional platelets, thrombogenic substances, free hemoglobin levels, and fat emboli.
