Introduction: heart surgery causes deep pathophysiological alterations, with a high risk of blood losses and the consequent danger for life. Objective: to evaluate the use of acute normovolemic hemodilution in patients exposed to coronary artery bypass surgery in an elective way. Methods: an observational, descriptive and cross-sectional study of 100 patients scheduled for elective coronary artery bypass surgery, with surgical risk II-III, according to the classification of the American Society of Anesthesiologists (ASA), assisted in the Cardiovascular Surgery Service of "Saturnino Lora Torres" Teaching Clinical Surgical Provincial Hospital in Santiago de Cuba, was carried out from September, 2012 to March, 2014. Results: there was a prevalence of men between 55 and 64 years; the hemathologic, hemodynamic and hemogasometric parameters, remained among the normal limits during the before bleeding, after bleeding and postself-transfusion times, there were no complications reports when performing the technique and there was a 97.0% of blood saving. Conclusions: the limited acute normovolemic hemodilution is a safe technique of blood saving for patients undergoing coronary artery bypass surgery
