With regard to increasing reservations as to homologous transfusions and the objective risks that they involve, since 1984 we have been using an autotransfusion technique in total hip arthroplasty constituting blood predeposit for hemodilution, and intra- and postoperative blood recovery. When this method was used postoperative complications were not very significant even when patients were high-risk (cardiopathic); furthermore, the use of homologous transfusions was required in 2.2% of the patients in 1994 as compared to 90% in 1985. The use of our orthopaedic protocol allows for rapid recovery of movement in the patient thus reducing time bed-ridden and related risks (DVT and/or PTE); the transfusion protocol allows for a return to normal of hemodynamic conditions a few days after surgery. Finally, the reduced incidence of complications caused by homologous transfusions (hepatitis, AIDS...) constitutes a financial saving for the government.
