Study of Influence of Delivery Method on the Neonatal Jaundice


Abstract
The indirect hyperbilirubinemia, regardless of the cause, is potentially toxic to the newborn brain, it must be dealt with aggressively terms of prevention, early detection and specific theraphy.
Present study was carried out to determine the influence of delivery method on the neonatal jaundice, a total of 672 cases of icteric infants were studied who were born at the Korea University Hospital during the period from April 1976 to September 1978.
The results obtained were summarized as follows.
1. Of 2,323 deliveries, the incidence of neonatal jaundice was 28.9% and significant influence of delivery method on the neonatal jaundice was observed (x2=64.69, p<0.01). The incidence of neonatal jaundice was significantly higher (p<0.01) in both infants born by cesarean section and breech delivery and slightly higher but not significant (p>0.05) in vacuum and forcep deliveries than normal..
2. By increasing gestational age, the incidence of neonatal jaundice has became decreased. The infants born before 36 weeks gestation showed significantly high (p<0.01) incidence of hyperbilirubinemia and low in infants born after 42 weeks,of gestation but not significant (p>0.05).
3. The weights of newborn infant were closely related with neonatal jaundice. The incidence of hyperbilirubinemia in infants with birth weight below 2.5 kg revealed significantly high and in infants with birth weight above 3.*5:kg, revealed relatively low.
4. Neonatal jaundice was found during the 2nd and 4th day of life and there was no significant influence of delivery method upon the time of appearance of hyperbilirubinemia.
5. The majority of cases (77.68%), had serum bilirubin level below 15mg/looml. Higher
~-,level was seen in both forceps and breech delivery group while in cesarian section and vacuum delivery group showed relatively low.
