Objective: To assist nurses in evaluating newborn jaundice more correctly and conveniently, we purported to set up user indicators for Transcutaneous Bilirubinometry (TCB). Materials and Methods: Babies born in a local teaching hospiteal, who were tested buy means of “TCB” and “heel-stick method” to compare the accountability and correlation of these two different values. Results: In this study, 190 newborns underwent testing with a total of 514 pairs of test values. All data were analyzed and were presented by the groups of babies with photo therapy (the number of values in pair is 108) and with non-photo therapy (n=406).The results were follows: (1) The bilirubin values of heel-stick method and TCB respectively were positively correlated, but the correlation coefficient value of photo therapy group (r=0.376,p<0.0001)was lower than of the non-photo therapy group (r=0.627,p<0.001). (2) Based on the analysis of non-photo therapy group, we set up a predictive equation: Y=2.77+0.65X (Y:heel-stick bilirubin value, X:TCB bilirubin value). A contrast reference table of the bilirubin values of heel-values of heel-stick and TCB was developed by using this equation, which could be used helpfully and friendly for the nurses using the same type of TCB. (3) According to the different indicated values of photo therapy, we established screening indications of TCB bilirubin values for the references of clinical situation. Conclusion: (1) Photo therapy will affect the accountability of a TCB’S bilirubin value. (2) The predictive equation that we set up is just applied for the newborn whose bilirubin value below 15 mg/dL.(Tzu Chi Med J 1999; 11:359-364)
