RESUMO
A clinical and hematological observation was performed on 136 newborn infants who were admitted to dept. of Pediatrics of Chosun University Hospital from Junly, 1976 to June, 1980 and were diagnosed of neonatal hyperbilirubinemia. The following results were obtained 1) The incidence of hyperbilirubinemia in male (64.0%) was more than female. 2) The highest monthly incidence was seen in June with 23 cases. (16.9%) 3) In the observation of the gestational period, its incidence was highest in full-term neonate with 103 cases. (79.3%). The mean value of serum bilirubin was highest in postmature neonate (19.70mg%). 4) In the obseervatio of the delivery type, the mean value of serum bilirubin was highest in vacuum and forcep delivery (17.81mg%). 5) The mean value of serum bilirubin was more higher in those of low birth weight group. 6) In the distribution of peak value of serum bilirubin, a group of 10.1~20.0mg% occupied 75.7%. 7) Idiopathic hyperbilirubinemia was the most common cause of pathological hyper bilirubinemia, with 79 cases. (58.1%). In the group of blood incompathibily, visible jaundice was begun earliest and mean value of serum bilirubin was highest. 8) Sepsis among the infection was the most important factor in the cause of neonatal hyper bilirubinemia with 18 cases (51.4%). 9) The most common blood types of mother-baby in ABO blood incompatibility was O-B with 8 cases (61.5%). 10) The exchange transfusions were performed on 13 cases (9.5%) and the rate of performance was the highest in blood incompatibility.
