[A total correction for tetralogy of Fallot without the use of homologous blood].
In 22 consecutive patients with tetralogy of Fallot (TF), a total correction was attempted without the use of a homologous blood transfusion from September 1995 to March 1997. The 22 patients were divided into two groups according to their surgical procedures; namely, either a simple correction (group I: n = 14) or a complex correction including the relief of peripheral pulmonary stenosis and/or the division of a previous systemic-pulmonary shunt (group II: n = 8). In 77% of all patients, surgery was performed without a homologous blood transfusion. No differences were found in the non-transfusion rate and the hematocrit (Ht) values between the two groups and, as a result, we thus confirm that this additional procedure is not a risk factor for surgery without a homologous blood transfusion. According to the correlation of the red blood cell volume before and after surgery, the preoperative Ht value corresponding to the postoperative Ht of 30% could be accurately predicted. The calculated Ht values were 41.0% in the patient weighing 15 kg, 42.5% in those weighing 10 kg, and 46.9% in those weighing 5 kg. These data suggest that a surgical correction without a homologous blood transfusion can therefore be safely performed in almost all patients with TF.
