Autologous Donor
the safest blood possible for transfusion
Autologous Blood
Why is autologous blood the safest blood for transfusion? (3)
o No risk of disease transmission, alloimmunization to red cells, platelets, WBCs, plasma proteins, transfusion reactions.
o Phlebotomy process stimulates the bone marrow to increase cell production
o Decreases the need for allogeneic blood and may actually increase supply for allogeneic blood supply.
Criteria for Autologous donation: (4)
- No age limit
- No strict weight requirement
- Hemoglobin/Hematocrit: should not be less than
11 g/dL and 33% - Frequency: Donations should not be more
frequent than every 3 days and the final donation

- Significant disease with ongoing symptoms but who have not been evaluated by the physicians
- Untreated aortic stenosis
TYPES OF AUTOLOGOUS DONATIONS / TRANSFUSIONS: (4)
- Pre-deposit donation
- Intraoperative autologous transfusion
- Immediate preoperative hemodilution
- Post-operative salvage
refers to the blood that is drawn some time before the anticipated transfusion and stored, usually liquid but occasionally frozen
Pre-deposit donation
occurs when blood is collected during the surgical procedure and usually reinfused immediately.
Intraoperative autologous transfusion
takes place in the operating room when 1-3 units of whole blood are collected and the patient’s volume is replaced with colloid or crystalloid. The blood is reinfused during the surgical procedure
Immediate preoperative hemodilution
autologous donation in which a drainage tube is placed in the surgical site, and post-operative bleeding is salvaged, cleaned and reinfused.
Post-operative salvage
