| Abstract |
|
57 newborn infants who were underwent exchange transfusion in Seoul National University Hospital
from Jan. 1970 to Sept. 1972 were analysed.
(1) 44% of the cases(25 cases among 57 cases) needed repeated exchange transfusions.
(2) There was a tendency of requring the:repeated exchange transfusion when the first exchange
transfusion was underwent in an earlier age.
⑶ There seemed to be no relationship between the birth weight and the frequency of exchange transfusion.
(4) 48% of the isoimmunized patients (14 cases among 29 cases) and 24% of non-isoimmunized
patients (6 cases among 25 cases) needed the repeated exchange transfusion.
(5) 4 types of bilirubin rebound were noticed after the exchange transfusion.
a. In 24 of 57 cases, the bilirubin rebound was so mild that only one exchange transfusion was
sufficient to treat the neonatal hyperbilirubinemia.
b. In 2 of 57 cases, the bilirubin rebound was almost absent.
c. In 13 of 57 cases, the bilirubin rebound was so high, almost equal to or above the pre-exchange
level, that the repeated exchange transfusion was needed.
d. In 11 o£ 57 cases, the bilirubin rebound was high above the level of 20 mg% but under the
pre- exchange level. The repeated exchange transfusion was also needed.
(6) The serum bilirubin level was decreased to 46. 5% of the pre-exchange level immediate after the
exchange transfusion.
