The utility of a growth factor: r-HuEPO as a treatment for preoperative autologous blood donation in gynecological tumor surgery.

Abstract

The use of r-HuEPO and sodium ferrous gluconate has been shown to be a safe and effective treatment which can be used by transfusional centers and surgeons to avoid allogeneic blood transfusions and to schedule short-term selective surgery. In this study the authors submitted 20 patients scheduled to undergo surgery for gynecological tumors to a program of pre-operative autologous blood donation. All the patients received both r-HuEPO and sodium ferrous gluconate in the pre- and post-donation period. r-HuEPO was administered subcutaneously in a dose of 200 IU/kg thrice weekly during the week before and after autologous blood donation (400 ml). Sodium ferrous gluconate was administered intravenously shortly before the first and fourth administration of 125 mg of r-HuEPO. Surgery was scheduled to be performed 10-15 days after the last r-HuEPo administration, i.e. within 15-20 days from blood donation. All the patients were tested for the following blood chemistry parameters: hematocrit, hemoglobin, sideremia and ferritin at treatment start, prior to donation, at treatment end, prior to autologous blood infusion and on the third and seventh day after surgery. No patient receiving r-HuEPO required allogeneic blood transfusion as both the hematocrit and hemoglobin values remained normal. r-HuEPO was observed to be a safe and effective treatment to be used in autologous blood donation programs in all patients scheduled to undergo surgery. It limits the decrease of hematocrit values following autologous blood donation thus enabling all the patients who for a variety of reasons to refuse allogeneic blood infusion to predeposit autologus blood shortly before the date scheduled for surgery.
