What Is Autologous Blood Transfusion?

Autologous blood transfusion is a transfusion in which a patient receives their own previously collected or recovered blood. The blood can be donated before planned surgery, collected immediately before an operation, or recovered during or after surgery. Using the patient's own red blood cells avoids exposure to donor red-cell antigens. The method selected depends on the operation, expected blood loss, patient condition, and available equipment.

Why Is Autologous Blood Transfusion Performed?

Autologous transfusion can reduce the need for allogeneic donor blood during operations expected to cause substantial blood loss. It is particularly useful when compatible donor blood is difficult to obtain or when minimizing donor exposure is a treatment goal. Intraoperative cell salvage is commonly used in selected cardiac, orthopedic, vascular, trauma, and other major surgical procedures. The technique is not necessary or suitable for every operation or patient.

How Is Autologous Blood Transfusion Performed?

Preoperative autologous donation collects and stores blood before an elective operation. Acute normovolemic hemodilution removes blood shortly before surgery while circulating volume is replaced, and the blood is returned later. Intraoperative cell salvage suctions shed blood from the surgical field, filters and washes the red cells, and reinfuses them through a transfusion system. Postoperative salvage can collect blood from selected surgical drains for processing and reinfusion.

What Is Recovery Like After Autologous Blood Transfusion?

Recovery is determined mainly by the surgery or illness rather than by the transfusion itself. Blood pressure, heart rate, hemoglobin, oxygen delivery, bleeding, and transfusion reactions are monitored during and after reinfusion. Patients who donated blood before surgery can develop anemia before the operation if collection exceeds their ability to replace red cells. Iron therapy or other blood-management measures can be used when appropriate.

What Are the Risks and Complications?

Autologous transfusion avoids some donor-related risks but is not risk free. Problems can include bacterial contamination, hemolysis, air embolism, clotting abnormalities, equipment failure, or clerical errors that result in the wrong blood being given. Cell salvage can be inappropriate when the collected field is heavily contaminated or contains substances that cannot be safely removed. Unnecessary preoperative donation can also cause anemia and lead to blood being collected but never used.

Frequently Asked Questions About Autologous Blood Transfusion

Is autologous blood transfusion safer than donor blood?

It avoids exposure to another person's red-cell antigens and some donor-related risks. It still has procedural, contamination, and transfusion risks of its own.

What is intraoperative cell salvage?

It is a technique that collects blood lost during surgery, processes the red cells, and returns them to the same patient during or shortly after the operation.

Can autologous blood be donated before surgery?

Yes. Preoperative autologous donation can be arranged for selected elective procedures, although it is used less often than in the past because modern donor blood is very safe and preoperative donation can cause anemia.

Can salvaged blood always be reinfused?

No. Heavy contamination, certain surgical materials, or other procedure-specific concerns can make cell salvage unsuitable. The surgical and transfusion teams determine whether recovered blood is safe to use.
