1. the injection of a volume of blood obtained from a healthy person (the donor) into the circulation of a patient (the recipient) whose blood is deficient in quantity or quality, through accident or disease. Direct transfusion from one person to another is rarely performed; usually packs of carefully stored blood of different blood group are kept in blood bank for use as necessary. During transfusion the blood is allowed to drip, under gravity, through a needle inserted into one of the recipient's veins. Blood transfusion is routine during major surgical operations in which much blood is likely to be lost.
2. the administration of any fluid, such as plasma or saline solution, into a patient's vein by means of a drip. See also autotransfusion.
