To evaluate the ability of the Gosset icterometer to identify the need for serum bilirubin measurement in premature infants we compared 269 icterometer readings with simultaneous serum bilirubin determinations in 90 premature infants of < 37 completed weeks of gestation. The relationship between serum bilirubin and icterometer values was different from that described in term infants. Mean serum bilirubin concentrations were lower at each icterometer level in premature infants than those reported in term babies. Neither interobserver variability nor the color balance of ambient light affected icterometry. Bilirubin estimates by first-time users were slightly less accurate than those made by experienced users. The icterometer provides reliable, cost-effective screening for clinically important hyperbilirubinemia in premature babies if a calibration curve specific for those infants is used. This simple device performs as well as electronic bilirubin meters when it is used in this manner.
为评估戈塞特黄疸计识别早产儿血清胆红素测量需求的能力，我们将269次黄疸计读数与90例妊娠<37周的早产儿同时进行的血清胆红素测定结果进行了比较。血清胆红素与黄疸计数值之间的关系与足月儿中描述的不同。早产儿在每个黄疸计水平下的平均血清胆红素浓度均低于足月儿报告的浓度。观察者间的变异性和环境光的颜色平衡均不影响黄疸计测量。首次使用者的胆红素估计值比经验丰富的使用者略不准确。如果使用针对这些婴儿的校准曲线，黄疸计可为早产儿临床上重要的高胆红素血症提供可靠、经济高效的筛查。以这种方式使用时，这种简单的设备与电子胆红素计的性能相当。
