Autologous blood donation with recombinant human erythropoietin for abdominal aortic aneurysm surgery

n = 12) who did not bank any autologous blood, and a donation group (n = 13) who did bank more than 800 ml of autologous blood with the use of erythropoietin. The hematocrit (Ht) level of the control group decreased from 41.1% ± 1.2% before the operation to 36.2% ± 0.9% just afterwards (P > 0.01). In the donation group, however, the Ht did not change significantly during either the donation period or the perioperative period. The postoperative period before oral food intake and natural defecation were both significantly shorter in the donation group than in the control group. The first day of mobilization was also earlier in the donation group. In conclusion, autologous blood donation using erythropoietin for AAA surgery is therefore considered to promote the early recovery of patients.
