[History of autologous blood transfusion in the 19th century]

Autologous blood transfusion in animal experiments was performed already in the first half of the 19th century. These experiments, however, were not conducted to explore the feasibility of autologous blood transfusion in man, but provided only the experimental design for physiological investigations on the defibrination of blood. Blood withdrawn from the animals by phlebotomy in these experiments was retransfused either with or without defibrination. The idea of retransfusing the patient's own blood was mentioned for the first time by Eulenburg and Landois, when in 1866 they proposed to treat gas poisonings with a type of exchange transfusion (transfusion with simultaneous depletory bleeding). They suggested that the blood that would be withdrawn could be retransfused after the poisonous gases had been eliminated. The first who demonstrably considered the possibility of autologous blood transfusion in operative medicine was the Halle surgeon Richard von Volkmann in 1868. The first originally sourced autologous blood transfusion, however, was performed by the Kiel surgeon Friedrich von Esmarch who, in a case of exarticulation of the thigh at the hip joint, collected the blood that had been shed during the operation in a washbowl, defibrinated it, and reinjected it into the severed femoral vein. However, despite some further cases of autologous blood transfusion performed for various indications and in different countries, the method was unable to gain a foothold in the treatment of acute blood loss, and fell into oblivion until the Leipzig gynaecologist Johannes Thies revived interest in it in 1914. The authors surmise that the advantages of autologous blood transfusion had not been recognised in the 19th century.
