[Hemoglobin follow-up of orthopedic autologous blood transfusion patients].

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.
