摘　　要：目的评价经皮胆红素各测定部位与血清总胆红素的相关性,选择更具代表性的测定部位。方法分别测定124例新生儿两眉弓连线中点、胸骨第二肋间正中、脐与剑突连线中点及前胫骨正中点的经皮胆红素及血清总胆红素浓度。结果新生儿两眉弓连线中点、胸骨第二肋间正中、脐与剑突连线中点、前胫骨正中点的经皮胆红素与血清总胆红素均呈线性相关(r=0.955,P<0.001;r=0.965,P<0.001;r=0.814,P<0.005;r=0.704,P<0.001)。胸骨第二肋间正中部位的经皮胆红素与血清总胆红素关联性最大(决定系数R2=0.931)。结论新生儿经皮胆红素首次测定部位应首选胸骨第二肋间正中。Objective To assess the correlation between the percutaneous bilirubin of each determining position and the serum total bilirubin,so as to choose a more representative position.Methods To determine the percutaneous bilirubin and the serum total bilirubin of 124 newborns at the following position： the mid point of the line segment linking the superciliary archs,the center of the intercostal spaces between the second and the third ribs,the mid point of the line segment linking the umbilicus and the xiphoid process and the center of anterior tibia.Result The percutaneous bilirubin of the newborns determined at above positions were linearly correlated with the serum total bilirubin（r=0.955,P〈0.001,r=0.965,P〈0.001,r=0.814,P〈0.005,r=0.704,P〈0.001）,of which the data got at the center of the intercostal spaces between the second and the third ribs were the most closely correlated（R2=0.931）.Conclusion The position selected for the first time determination of a newborn＇s percutaneous bilirubin should be at the center of the intercostal spaces between the second and the third ribs.
