[Perioperative blood transfusions. Changed indications and new alternatives].
The surgeon has to keep abreast of changing advantages and disadvantages as well as alternatives in the context of homologous blood transfusions. We ought to realise that normovolaemic anaemia is better tolerated than we used to assume in the past. It is no longer necessary to provide transfusions to patients with 10 g/% Hb. About 8 g/% should rather be considered the adequate threshold. Possible transmission of hepatitis and AIDS virus is a genuine risk associated with blood transfusion. No hard evidence has yet been produced to immunosuppression and effects on the prognosis of cancer patients. More attention will have to be given in the future to preoperative supply of blood for autohaemotherapy.
