Cell Salvage

What it is

A technique that collects blood lost during surgery, washes and filters it, then returns it to the patient. No donor blood involved.

If you accept vs. refuse

Accept Why some people accept
  • Uses your own blood — no donor blood involved
  • Reduces need for allogeneic transfusion by up to 39% (Cochrane Review)
  • Recommended by WHO Patient Blood Management guidelines
  • Blood stays in a closed circuit connected to your body
Refuse Why some people refuse
  • Some consider blood that has left the body to be no longer part of the person
  • Requires specialized equipment (Cell Saver machine) not available at all facilities
  • In some interpretations, the temporary external storage conflicts with religious beliefs

Autologous Procedure Hemodilution Blood is drawn immediately before surgery and replaced with IV fluids. The blood is returned to the patient after surgery, reducing the loss of concentrated blood.
Glossary Autologous From oneself. Autologous procedures use the patient's own blood, not blood from a donor.
