There are two different methods of autotransfusion during an operation; one without blood washing and the other with wash red cells obtained after the filtering and concentration of the recovered blood. The first method has the advantage of being simple and cheap while recovering 1500-2000 ml of blood. Nevertheless it is insufficient in the case of an important or rapid bleeding. The weight of haemoglobin in the recovered blood is relatively low and the hemolysis is without clinical consequences. The rate of the coagulation factors is reduced. The autotransfusion with wash red cells requires a more important investment at the beginning. But the washing process eliminates the cell micro-aggregates and nearly all of the substances in the recovered blood. Therefore concentrated units of red cells may be obtained with hematocrits between 45 and 65%. Autotransfusion with washing offers a greater security when the bleeding is important or violent. The autotransfusion is useful for a bleeding between 1 and 3 litres. The average volume recovered corresponds to 2.5 pockets of blood extract, thus covering the costs for the kits. If the bleeding exceeds 1.5 times the blood volume, blood extract and plasma will be required in addition. The risk of homologue blood transfusion can only increase the development of autotransfusion techniques and particularly the recovery of blood during the operation process.
