RESUMEN
Autologous blood donation before elective surgery has been widely endorsed as good transfusion practice. Although only 6 percent of patients undergoing elective orthopedic surgery are unable to donate 3 autologous units, 40 percent cannot donate 4 units because they become anemic [1,2]. According to the results of our study this must be due to different problems in bone marrow dynamics, which cannot be overcome by unselected use of human recombinant erythropoietin alone [3].

Patients undergoing autologous donation prior to elective orthopedic surgery show better Hb values during the perioperative period compared to those without autologous donation, all patients in both groups receiving no homologous transfusion. The widely assumed improvement of Hb regeneration during the postoperative period according to an erythropoiesis stimulated by preoperative autologous donation is not supported by our data.
