Abstract

PURPOSE:

Allogenic blood transfusions have a risk of infection owing to unknown organisms, graft-versus-host reaction, and immunosupression; however, the use of autologous blood has been reported to be safe. Cord blood has been reported to be useful as a source of stem cell transplantation for the treatment of leukemia and genetic disease. Furthermore, autologous cord-blood transfusions (ACBT) have been reported to be effective for the treatment of anemia in premature infants. The authors examined the efficacy of ACBT in neonatal surgical patients.

METHODS:

Autologous cord-blood was stored from 12 infants at delivery, including 2 transvaginal and 10 cesarean section deliveries, from 1998 to 2001. All infants had surgically correctable malformations diagnosed antenatally. The mean gestational age was 37.2 +/- 1.6 weeks, and the birth weight was 2,597 +/- 1.6 g. The results of the blood count, serum electrolyte, and liver function tests of the patients who underwent ACBT only (group 1, n = 7) were compared with those of the 7 neonates who underwent an allogenic transfusion during the same period (group 2, n = 7).

RESULTS:

The mean volume of the stored blood was 64 +/- 35.6 g (range, 20 to 100). Eleven of the 12 patients underwent transfusions. Ten of 11 patients received autologous cord blood. A mean of 44.1 +/- 37.3 g of cord blood was used. Three of 10 cases also required an allotransfusion because of ECMO circuit preparation and a shortage of the stored blood. One patient underwent allotransfusion only. As a result, 7 of 11 babies (64%) who required transfusion were able to avoid an allotransfusion. The blood potassium levels were lower in group 1 than in group 2. No significant complications were recognized clinically.

CONCLUSIONS:

ACBT is considered beneficial because it enables neonatal surgical patients to avoid allotransfusions. Therefore, autologous cord-blood storage should be considered in the patients antenatally diagnosed to have surgical malformations. However, the storage volume varies for each case. Improved techniques to obtain an adequate amount of blood also should be developed.
