Advantages of autologous blood transfusion

Everyone who has been to college knows that the school organizes voluntary blood donation every year. We only know that the blood will be used on patients, but we don’t know which patients it will be used on or what diseases require blood transfusions. In fact, blood transfusion is not the only way to use other people's blood. Autologous blood transfusion can also be used when you are sick. This method of blood transfusion can avoid related infections. The following introduces the benefits of autologous blood transfusion, let’s take a look.

Advantages of autologous blood transfusion:

It can avoid transfusion-related infections such as hepatitis virus, HIV and other blood-borne pathogens. 1.

It can not only avoid the production of alloantibodies and prevent graft-versus-host disease, but also avoid hemolysis, fever, allergies caused by allogeneic immunity and unfortunate accidents caused by errors in allogeneic matching. 2.

It can reduce the early recurrence rate of tumors after surgery caused by immunosuppression caused by allogeneic blood. 3.

Isovolumetric hemodilution autologous blood transfusion can reduce blood viscosity, improve microcirculation, increase tissue oxygen transport capacity, and reduce the loss of coagulation substances. 4.

The blood collected during surgery is collected through an autologous blood recovery machine, and concentrated red blood cells are obtained through filtration, washing, centrifugation and concentration, so that no or less allogeneic blood is used. 5.

There is no need for cross-matching of blood before transfusion and the blood fees generated by transfusion, which saves costs. 6.

Blood use for special groups (such as patients with rare blood types, patients who refuse to use other people's blood due to religious beliefs, patients in areas with difficult blood supply, etc.) 7.

Contraindications of autologous blood transfusion:

1. The blood has been contaminated by bacteria

2. Blood may be contaminated by tumor cells

3. Patients with severe anemia and coagulation disorders

4. Patients with sepsis or bacteremia

5. Open chest or abdominal injuries lasting more than 4 hours or blood remaining in the body cavity for too long

6. People with major organ dysfunction

Adverse reactions of autologous blood transfusion:

Too rapid bloodletting during diluted autologous blood transfusion can cause a drop in blood pressure or even hypovolemic shock. Excessive infusion may cause acute pulmonary edema due to excessive cardiac load. 1.

Multiple blood draws before storage autologous blood transfusion surgery can easily cause insufficient blood volume in the patient, and blood donation reactions may occur during the blood collection process. 2.

Recycling autologous blood transfusion may cause consumption of coagulation factors and platelets in patients, leading to DIC. Improper collection or storage before infusion can easily lead to hemolytic reactions. 3.
