Using the transcutaneous bilirubinometer, we studied the response of cutaneous bilirubin to different colors of light during phototherapy. Three groups of ten infants were exposed to blue, green, and blue-green lights at a mean postnatal age ranging from 50 to 77 hours. Patched areas served as controls. Every 15 minutes during four hours of phototherapy, we obtained simultaneous measurements from exposed and covered areas. After the onset of phototherapy, transcutaneous bilirubinometer values from the covered areas in all groups remained stable. The overall rate of bleaching was lowest in the green light group and highest in the blue-green combination group. In this group of infants, green light appeared to enhance the effectiveness of blue light in reducing dermal bilirubin concentrations as measured by the transcutaneous bilirubinometer.
我们使用经皮胆红素测定仪，研究了光疗期间皮肤胆红素对不同颜色光线的反应。三组各十名婴儿在出生后平均年龄50至77小时时分别暴露于蓝光、绿光和蓝绿光下。未照射的部位作为对照。在四小时的光疗期间，每隔15分钟，我们同时测量暴露部位和遮盖部位的胆红素值。光疗开始后，所有组中遮盖部位的经皮胆红素测定仪值保持稳定。绿光组的总体退黄率最低，蓝绿组合光组最高。在这组婴儿中，经皮胆红素测定仪测量结果显示，绿光似乎增强了蓝光降低皮肤胆红素浓度的效果。
