新生儿败血症血清降钙素原检测的结果分析

目的评价血清降钙素原（procalcitonin,PCT）检测在诊断新生儿败血症中的应用价值。方法对所研究对象进行血清PCT检测和血培养,并对结果进行分析。结果败血症患儿中PCT阳性率高于血培养阳性率;与对照组相比,败血症组PCT阳性率差异有统计学意义（P〈0.05）,PCT对诊断新生儿败血症的灵敏度为82.1%,特异度为90%。结论 PCT检测可以作为早期诊断新生儿败血症快速灵敏的参考指标。

Analysis of serum procalcitonin detection in neonatal septicemia

Objective To evaluate the serum procalcitonin（ PCT） detection in diagnosis of neonatal septicemia.Methods The research object was detected by PCT in serum and blood culture, and analyzed the Results.Results The positive rate of PCT was higher in children with septicemia than the positive rate of blood culture; compared with the control group, there were statistically significant differences in the positive rate of PCT in sepsis group（P〈0.05）, the sensitivity of PCT for neonatal septicemia was 82.1%, the specificity was 90%.Conclusion PCT detection can be used as quick reference index in the early diagnosis of neonatal sepsis.
