ABSTRACT: 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.
