[Evolution of autotransfusion: effect of a diet with and without the ingestion of iron]

The efficiency of an autotransfusion program was studied over two groups of patients undergoing an elective surgery. The A group (n = 41) was on dietotherapy program associated with a supplement of ferrous sulfate and the B group (n = 35) on dietary intervention only. Red cell volume (RCV), haemoglobin (Hb) and haematocrit (Ht) were determined previously to the autotransfusion, during the same and before the surgical intervention. Serum ferritin levels were measured in the B group patients previous to the autotransfusion and before the surgical intervention. No statistically significant differences were observed among the two groups with regard to the RVC variations, Hb or Ht during the autotransfusion process. Although 85% of the A group patients showed secondary digestive effects due to oral ferrous therapy, no patients from the B group showed any sign of these effects whatsoever. The results of the present study suggest that a diet rich in easily bioavailable iron could be an alternative therapy during the autotransfusion procedure.
