摘    要:目的探讨碳氧血红蛋白(COHb)辅助诊断新生儿溶血病的价值。方法 选择2009年10月至2010年9月本科收治的足月儿,确诊新生儿溶血病者为溶血组,存在母子血型不合和病理性黄疸但未确诊溶血病者为非溶血性黄疸组,无母子血型不合及病理性黄疸者为对照组。分别于生后5天内测定COHb、血红蛋白(Hb)、网织红细胞(Ret)和总胆红素(STB),并进行比较。建立受试者工作曲线(ROC曲线),确定COHb、Hb、Ret的曲线下面积(AUC),同时分析三者不同截断值的敏感度、特异度、阳性和阴性预测值。结果 (1)溶血组COHb、Ret和STB较非溶血性黄疸组及对照组增高,Hb降低(P均〈0.001);非溶血性黄疸组STB较对照组增高(P〈0.001),但COHb、Hb和Ret差异无统计学意义(P〉0.05)。(2)COHb、Hb和Ret的AUC分别为96.0%、74.9%、85.7%,三者比较差异有统计学意义(P〈0.05)。COHb预计溶血病的最佳截断值为1.2%(敏感度86.8%、特异度91.2%、阳性预测值93.0%、阴性预测值83.9%),敏感度、特异度均优于Hb和Ret。三指标联合诊断的特异度可提高到98.2%。结论 COHb是敏感的新生儿溶血病诊断指标,与Hb和Ret联合检测,对于早期筛查和辅助诊断新生儿溶血病有重要意义。

关 键 词:碳氧血红蛋白  溶血症,新生儿  ROC曲线

Abstract:Objective To study the diagnostic value of carboxyhemoglobin(COHb) on hemolytic disease of the newborn(HDN).Methods Full-term infants diagosed serologically with HDN in our department from October,2009 to September,2010 were categorized as hemolytic group.Infants with ABO or Rh blood group incompatibility and pathologic jaundice but without HDN were categorized as non-hemolytic jaundice group,while those without blood group incompatibility and pathologic jaundice were studied as contol.COHb level,serum tota...
Keywords:Carboxyhemoglobin  Hemolytic disease of newborn  ROC curve
