  • Abstracts - Problem of Transcutaneous Bilirubinometry
    home within 24 48 h after birth the prediction of severe hyperbilirubinaemia requiring treatment is important We tested the prediction of the need for phototherapy by measuring the yellow skin colour and the progression in yellow skin colour over 6 h using transcutaneous bilirubinometry TcB during the first 33 h of age The first TcB reading at median 21 h 11 33 h 5th and 95th percentiles of age and

    transcutaneous assessment Depending on the desired exactitude and the prevailing consensus on plasma bilirubin determination it is possible to halve the necessary number of blood tests However the yellow colour of the skin is influenced by several factors Thus transcutaneous measurements of the plasma bilirubin concentration are inaccurate The yellow colour of the skin should be considered as an important parameter which at least theoretically provides information concerning the risk

    METHODS Three hundred and seventy seven newborn babies admitted to the neonatal intensive care unit for various causes were included in the study When the plasma bilirubin concentration needed to be determined for clinical reasons the extent of the yellow skin colour was measured transcutaneously using a jaundice meter The haemoglobin concentration was also determined This had no independent influence on the jaundice meter readings The yellow skin colour was

    birth The estimation of TcBI is simple quick reliable and non traumatic to the newborn with no workload on the laboratory and technician However different nomograms are to be prepared for different laboratories as also for the newborns with difference in skin pigmentation gestational age and after phototherapy SBI determined by filter paper technique eliminates these limitations Moreover the linear correlation was stronger between SBI and Diazo values r 0

    TcBI was correlated with serum bilirubin estimated by conventional diazo method Forty babies required phototherapy in 20 an area of 2 5 cm2 over the forehead was covered during phototherapy to make an unexposed window for TcBI estimation The other 20 newborns received phototherapy as such and TcBI was estimated on the forehead There was a linear relationship between serum bilirubin level and TcBI estimated at the forehead r 0

  • Abstracts - Problem of Transcutaneous Bilirubinometry
    concentration in neonates using a transcutaneous noninvasive jaundice meter is significantly affected by many factors such as gestational age birthweight phototherapy and skin pigmentation In an attempt to minimize the influence of skin color and hence circumvent the need for standardization curves for different ethnic populations we obtained noninvasive jaundice meter readings from the infant s midsternum within 4 hours of birth and subtracted this measurement from subsequent reading in
