  • Abstracts - Problem of Transcutaneous Bilirubinometry
    measurements were carried out in various points of body The maximal value of the device readings and maximal correlation r 0 9 with biochemical method were reached by measurements on sternum For children with illnes duration up to 3 days the noninvasive measurement results were found a little bit underestimated in comparison with real bilirubin content in blood This may be the effect of delay in one two days in complete painting of subcutaneous fabrics by yellow pigment By illness duration more than 3 days there were observed no appreciable deviations between the methods The result of noninvasive examination of bilirubinemia degree depends on such physical parameters of biofabric of the person as thickness of the skin subcutaneous adipose tissue skin pigmentation amount of blood vessels in subcutaneous cellular tissue The variation of device readings from real bilirubin content is in dependence to individual peculiarities of physical parameters of infant biofabric In case of insignificant bilirubinemia level the readings of BILITEST were found comparable to blood bilirubin concentration It makes the noninvasive method usable by viral hepatitis disease only for bilirubinemia level estimation meaning possibility of understating of measurement results in first days of disease By noninvasive monitoring of bilirubinemia

    bilirubin level was assessed in a group of jaundiced low birth weight infants using three different methods Transcutaneous bilirubinometry was compared with conventional capillary and arterial methods to investigate the over or underestimation of neonatal jaundice Sampling site did not influence bilirubin levels Capillary and arterial results showed a linear correlation r 0 9 suggesting no influence of environmental light on peripheral bilirubin isomerization Similar results were obtained comparing both

    blood tests These studies have not allowed an estimation of the magnitude of such a benefit OBJECTIVES To evaluate the accuracy of TcB as a method of determining the need for serum bilirubin SBR measurements in full term babies and to quantify the magnitude of any benefit SUBJECTS Babies born at more than 34 weeks gestation who had not previously been exposed to phototherapy and were requiring blood sampling in the first week of life Method TcB measurements were made at the same time as blood sampling SBR was measured in all blood samples For jaundiced babies the ability of TcB to detect significant jaundice SBR 249 micromol l was evaluated RESULTS There was a correlation between SBR and TcB measurements n 303 r 0 76 p 0 0001 but the 95 prediction interval for SBR from TcB was wide 88 3 micromol l For the 285 jaundiced babies the area under the receiver operator characteristic curve was 0 89 A TcB value of 18 detected significant jaundice with a sensitivity of 100 and a specificity 95 confidence interval of 45 39 to 51 If blood samples had only been taken from babies with a TcB value greater than 18
