| blood transfusion reaction | This refers to an immune response against transfused blood cells. Antigens, on the surface of red blood cells, are recognised as foreign proteins and can stimulate sensitised lymphocytes to produce antibodies to the red blood cell antigens. This triggers a complex immunological reaction that results in the destruction of the transfused red blood cell. The blood groups (A, B, AB, O) are classified on the basis of the presence of surface antigens on the red blood cell. Type A blood has A antigens. The plasma component of the blood contains the antibodies against all other blood group antigens other that its own. Another type of surface antigen is known as Rh factor. Rh factor is either present (Rh positive) or absent (Rh negative). Rh compatibility is another requirement for blood transfusion. Symptoms and findings of a transfusion reaction include flank pain, fever, chills, bloody urine, rash, low blood pressure, dizziness and fainting. (27 Sep 1997) |

| reciprocal transfusion | An attempt to confer immunity by transfusing blood taken from a donor into a receiver suffering from the same affection, the balance being maintained by transfusing an equal amount from the receiver to the donor. (05 Mar 2000) |
| mediate transfusion | Transfusion into a patient of blood previously obtained from a donor and stored in a suitable container. Synonym: mediate transfusion. (05 Mar 2000) |
| peritoneal transfusion | The injection of saline solution or other fluid into the peritoneal cavity. (05 Mar 2000) |
| placental transfusion | Return to the newborn via the umbilical vessels some of the foetal placental blood. (05 Mar 2000) |

| subcutaneous transfusion | An infusion of absorbable solutions beneath the skin. (05 Mar 2000) |
| direct transfusion | Transfusion of blood from the donor to the receptor, either through a tube connecting their blood or by suturing the vessels together. Synonym: immediate transfusion. (05 Mar 2000) |
| drip transfusion | Transfusion slow enough to measure by drops. (05 Mar 2000) |
| immediate transfusion | Transfusion of blood from the donor to the receptor, either through a tube connecting their blood or by suturing the vessels together. Synonym: immediate transfusion. (05 Mar 2000) |
| incompatible blood transfusion reaction | A syndrome due to intravascular haemolysis of transfused blood by serum antibodies of the recipient, which react with an antigen of the donor red cells; characterised by chills, fever (often with urticaria), backache or muscle cramps, haemoglobinaemia, haemoglobinuria, and oliguria, which may result in acute renal failure, DIC, and death. (05 Mar 2000) |
| indirect transfusion | Transfusion into a patient of blood previously obtained from a donor and stored in a suitable container. Synonym: mediate transfusion. (05 Mar 2000) |
| intrauterine transfusion | To treat erythroblastosis foetalis, Rh-negative blood is placed into the peritoneal cavity of the foetus. (05 Mar 2000) |
| total transfusion | Removal of most of a patient's blood followed by introduction of an equal amount from donors. Synonym: exsanguination transfusion, substitution transfusion, total transfusion. (05 Mar 2000) |
