autologous blood transfusion


Also found in: Dictionary, Thesaurus, Encyclopedia.

autologous blood transfusion

1. The collection of a patient's own blood before surgery, to be used if the patient needs a transfusion during or after the surgery, to reduce the possibility of needing banked blood, and with it the risk of having a transfusion reaction or contracting a transmissible infection.

Patient care

The usual blood transfusion checks are performed: the patient's armband name and number are verified by comparing them with those on the chart; the number and blood type of the unit of blood are checked against those of the patient; and the number and blood type of the unit of blood should match that information on all the paperwork.

2. The collection and reinfusion into the patient of blood lost during an operation.

transfusion

the introduction of whole blood or blood components directly into the bloodstream. Among the elements transfused, in addition to whole blood, are packed red blood cells, plasma, platelets, granulocytes and cryoprecipitate, a plasma protein rich in antihemophilic factor VIII. See also autotransfusion.

autologous blood transfusion
transfusion of the animal's own blood.
blood transfusion
whole blood is most often indicated to maintain or replace blood volume, to provide deficient blood elements and improve coagulation, to maintain or improve transport of oxygen, and in liver failure in which toxins accumulate in the blood, or in some other types of toxemia.
direct transfusion
transfer of whole blood from the donor through a tube, directly to the recipient.
exchange transfusion
blood is removed from the recipient at the same time and in the same amount as blood is being administered from the donor.
incompatible transfusion
see transfusion reaction (below).
transfusion reaction
a group of clinical signs due to antibody in the recipient's blood reacting with the transfused red blood cells when blood for transfusion is incorrectly matched, or when the recipient has an adverse reaction to some element of the donor blood. Most commonly, there is an immune-mediated hemolysis involving alloantibodies, which may be naturally occurring or the result of an earlier transfusion, in the recipient's serum and the donor's erythrocytes. In ruminants, signs appear during the transfusion, beginning with hiccough, then tremor, dyspnea, lacrimation, fever, ruminal tympany, hemoglobinuria and subsequent abortion. If death occurs, it is because of pulmonary edema. Similar signs are seen in other species. Urticaria and erythema sometimes occur in dogs and cats.
Nonimmunological transfusion reactions include cardiovascular overload, hypocalcemic tetany from citrate (used as the anticoagulant) overload, and disease transmission.
transfusion therapy
the administration of whole blood or blood components, usually in the treatment of bleeding disorders.
