Objective:
To evaluate the role of recombinant human erythropoietin in reducing the need for homologous blood transfusion during operations by studying its effect on the recovery of postoperative anaemia.
Design:
Randomised controlled trial.
Setting:
University hospital, Japan.
Subjects:
10 patients with gastric cancer undergoing distal gastrectomy.
Interventions:
5 Patients were given erythropoietin 200 IU/kg/day together with ferric pyrophosphate 40 mg/day intravenously for seven days before operation and 14 days afterwards, and 5 were given ferric pyrophosphate 40 mg/day alone (control group).
Main Outcome Measures:
Packed cell volume, haemoglobin concentration, and white and red cell counts.
Results:
There was no significant change in packed cell volume after the operation in the erythropoietin group, but in the control group it dropped from a mean (SD) of 0.378 (0.074) before operation to 0.329 (0.068) on day 1 (p < 0.05). Haemoglobin concentrations were significantly higher in the erythropoietin group than the control group on day 7 (mean (SD) 137 (14) compared with 110 (19) p < 0.05), and on day 10 (140 (9) compared with 108 (15) p < 0.01) after operation.
Conclusion:
Erythropoietin prevented postoperative anaemia after gastrectomy as judged by packed cell volume, haemoglobin concentration, and red cell count. Erythropoietin given before and after operation therefore has the potential to reduce the need for homologous blood transfusion during and after major operations.
