摘要
目的：评估足月新生儿及早产儿经皮胆红素（ＴｃＢ）测定的临床应用价值。方法：测定３９例足月儿、１３例早产儿的血清总胆红素值及额部、胸骨处的ＴｃＢ读数，并对两者作直线相关分析。结果：足月儿的ＴｃＢ读数与血清总胆红素值显著相关（ｒ＝０．８８６，Ｐ＜０．００１），而早产儿两者之间无显著相关（ｒ＝０．２２１，Ｐ＞０．２５）；足月儿额部、胸骨中部ＴｃＢ测定的重复性相近。结论：足月儿可依额部或胸骨中部ＴｃＢ读数推算出血清总胆红素值，但该值与ＴｃＢ测定仪提供的数值差别较大。各实验室应建立自己的ＴｃＢ读数与血清总胆红素值之间的对应关系。ＴｃＢ测定应用于监测早产儿高胆红素血症时应慎重。
Objective: To
evaluate the clinical values of transcutaneous bilirubin(TcB) measurements in fullterm infants
and in premature neonates. Methods: Transcutaneous bilirubin(TcB) measurements and total
serum bilirubin determinations were performed in 39 fullterm infants and 13 premature infants
and the data were submitted for linear correlation analysis. Results: TcB reading was correlated
well with serum bilirubin level in fullterm infants(r=0.886,P<0.001),but not in premature
neonates(r=0.21,P>0.25).The repeating of TcB tests on the forehead and on the midsternum was
similar(2=0.81,P>0.05). Conclusion: The serum bilirubin values can be computed from TcB
reading according to our regression,However,those values are different from the values
suggested by the company of TcB meter.It is important to recognize that each institution should
establish its own criteria for the use of this instrument and that TcB measurements can hardly
be recommended for the indentification of hyperbilirubinemia in premature infants.
