title: [Maternal and umbilical bilirubin concentration at the time of delivery depending on course of pregnancy and labour].
abstract: OBJECTIVE
  Newborns hyperbilirubinemia is an interesting, complicated and controversial clinical problem. An elevated concentration of it can be connected with increased risk of jaundice. Also, maternal bilirubin can play a part in the development of jaundice in mature newborns.
  
  
  METHODS
  The research included a group of 173 healthy, full-term newborns in generally good condition, with body mass between 5 and 95 percentile. Infants were born in 2002 at 1st Department of Obstetrics and Gynaecology Medical University in Warsaw. The maternal blood was collected during labour and the umbilical blood was collected immediately after delivery.
  
  
  RESULTS
  The mean value of maternal bilirubin was 0.62 mg/dl, and of total bilirubin in the umbilical blood was 1.61 mg/dl.
  
  
  CONCLUSIONS
  The differences between respective values in children delivered by caesarean section, whose mothers suffered from the infection during pregnancy or narcotic analgetic drugs that had been administered during labour were not statistically significant. Maternal bilirubin was higher in mothers with proteins < 6.0 g/dl. The umbilical bilirubin was statistically increased in children whose mothers oxytocin received.
