摘　　要：Justifications: Perioperative allogeneic blood transfusion can be reduced or even completely avoided by using a set of different strategies: meticulous hemostasis, the use of pharmaceutical agents that assist in the process of coagulation/ fibrinolysis, the use of blood substitutes, induced hypotension, preoperative autologous blood donation, collection and reinfusion of autologous blood during the operation, as well as from acute normovolemic hemodilution (ANH). Contents: ANH consists of taking a percentage of the patient’s blood volume and a concurrent infusion of acellular fluids in order to maintain normovolemia. As a consequence, a hemodiluted patient will lose less blood cells for each blood volume that is lost during the surgical procedure. The aim of this study is to clarify doubts and provide practical information relative to the procedure of ANH through the author’s own experiences as well as literary examples. Conclusions: ANH is an easy and cheap technique performed during the intraoperative period useful to reduce the use of hemoderivatives.Justifications: Perioperative allogeneic blood transfusion can be reduced or even completely avoided by using a set of different strategies: meticulous hemostasis, the use of pharmaceutical agents that assist in the process of coagulation/ fibrinolysis, the use of blood substitutes, induced hypotension, preoperative autologous blood donation, collection and reinfusion of autologous blood during the operation, as well as from acute normovolemic hemodilution (ANH).
