K. Imura et al., Usefulness of cord-blood harvesting for autologous transfusion in surgicalnewborns with antenatal diagnosis of congenital anomalies, J PED SURG, 36(6), 2001, pp. 851-854
Background/Purpose: The risks of homologous transfusion and the effectivene
ss of predeposit autologous transfusion have been described. The authors ex
amined the clinical usefulness of cord-blood harvesting for autologous tran
sfusion in newborns who had congenital anomalies antenatally diagnosed that
would require surgical intervention at or near the time of delivery.
Methods: Of 112 cases of antenatal diagnosis of congenital anomalies, 50 mo
thers gave informed consent and enrolled in this study. Cord-blood was with
drawn immediately after clamping of the umbilical cord and was used for aut
ologous transfusion in newborns within the first 3 days postpartum.
Results: A mean of 72 +/- 54 mt of cord-blood was harvested (27 +/- 18 mL/k
g). While preserving cord-blood for 3 days at 4 degreesC, no signs of clot
formation or hemolysis were observed. The harvested cord-blood included pla
sma-free Hb ranging from 1 to 68 (13 +/- 18) mg/dL and thrombin-antithrombi
n III complex ranging from 2 to 273 (18 +/- 50) ng/mL. Bacteriologic examin
ation of the stored cord-blood showed negative cultures, except for samples
from 3 newborns after vaginal delivery. A mean of 46 +/- 34 mt of cord-blo
od was used in 26 patients for autologous transfusion. No significant compl
ications related to cord-blood transfusion were recognized clinically.
Conclusions: Autologous cord-blood transfusion has the potential to be a us
eful alternative to homologous transfusion in newborns requiring surgery. A
dequate collection and storage techniques for cord-blood must be developed.
