  • Title: Epoetin alfa plus autologous blood donation and normovolemic hemodilution in patients scheduled for orthopedic or vascular surgery.
    Author: Tryba M.
    Journal: Semin Hematol; 1996 Apr; 33(2 Suppl 2):34-6; discussion 37-8. PubMed ID: 8723580.
    Abstract:
    In previous studies, treatment with epoetin alfa facilitated preoperative donation of autologous blood (AB). However, some patients may not be able to donate sufficient AB to meet their surgical blood requirements when the time to surgery is short. In this multicenter, double-blind, placebo-controlled study, the ability of epoetin alfa combined with normovolemic hemodilution (NVHD) to facilitate the collection of > or = 4 AB units within 2 weeks of surgery was investigated in 112 nonanemic patients scheduled for elective orthopedic or vascular surgery. All patients received oral iron supplementation and were treated with three intravenous (i.v.) injections of epoetin alfa (300 or 600 IU/kg) on days 1,4, and 7; surgery, in combination with NVHD, was performed on day 13. A total of 4 units of AB were predeposited if the patient's hemoglobin (Hb) level exceeded 11 g/dL at each donation. Compared with placebo, epoetin alfa dose-dependently increased reticulocyte counts prior to surgery and significantly minimized the decrease in hematocrit (Hct) associated with AB donation, although there were no significant differences between dosages. While significantly more patients treated with epoetin alfa were able to donate > or = 4 AB units compared with placebo, there was no difference between the groups in exposure to allogeneic blood. This effect of epoetin alfa was particularly apparent in female patients. I.v. epoetin alfa 300 IU/kg, administered three times within 1 week, appears to be the optimum dose for facilitating the collection of > or = 4 units of AB in nonanemic patients scheduled for elective surgery and NVHD within 2 weeks.
