Autologous blood transfusion today.
Autologous blood transfusion--the transfusion to a patient of his or her own blood--is increasingly being recognised as a useful adjunct to traditional transfusion practice. The reasons include fears of disease transmission, the potential adverse effects on the recipient's immune system of transfused donor blood, and logistical factors. The three main techniques of autologous transfusion are: (i) pre-deposit, in which patients donate blood over a period of time in preparation for elective surgery; (ii) pre-operative isovolaemic haemodilution, in which blood is removed immediately before surgery and volume replacement is given, the blood being reinfused post-operatively; and (iii) salvage transfusion--the collection of blood shed at surgery or in similar circumstances, which is reinfused immediately or after concentration and purification. All three techniques can help to improve the safety of transfusion and economise on scarce supplies of donor blood.
