Canadian Surgeons and the Introduction of Blood Transfusion in War Surgery

Canadian surgeons serving in the Canadian Army Medical Corps in the First World War were responsible for introducing transfusion in the management of war casualties to the British Army. They were uniquely placed to do so by a coincidence of circumstances. They were aware of developments occurring in the field of blood transfusion in the United States, which was at the time leading the research and development of transfusion as a therapeutic measure. The ties between Britain and Canada in 1914 were such that Canada entered the war immediately, and Canadians served closely with the British, volunteering promptly and in large numbers. Britain, by contrast with the United States, had little interest in or expertise with blood transfusion. Thus, Canadian surgeons went to war aware of the value of blood transfusion and with some who had actually learned how to use transfusion. They arrived to find no interest or expertise on the part of their British colleagues and had to work hard to convince them of the merits of blood transfusion in the management of hemorrhage. Their efforts were reinforced by the arrival in 1917 of American surgeons bringing their experience with transfusion. By war's end, blood transfusion was generally accepted as the treatment of choice for severe blood loss.
