老年重症感染患者诊断中降钙素原与C-反应蛋白联合检测临床价值分析

摘要

目的：探讨老年重症感染患者诊断中血清降钙素原(PCT)与C-反应蛋白(CRP)联合检测临床价值。方法选择80例我院老年重症感染患者作为观察组﹐并以80例老年非感染性患者作为对照组﹐采集两组患者的空腹静脉血样﹐比较两组患者血清中PCT和CRP的含量及检测的阳性率等。结果观察组血清中PCT检测阳性率92.5﹪﹐PCT﹑CRP的平均含量均明显高于对照组﹐差异均具有统计学意义(<0.05)﹔但观察组CRP阳性率与对照组差异无统计学意义(<0.05)。结论 PCT特异性较CRP高﹐稳定性较好﹐PCT和CRP联合检测可考虑作为老年重症感染患者严重感染的重要指标。%Objective To investigate the diagnosis value of serum procalcitonin (PCT)combined with C-reactive protein (CRP)in elderly patients with severe infection.Methods 80 cases of severe infections in elderly patients in our hospital as the observation group,and 80 cases of elderly patients with non-infectious as the control group,two groups of patients collected fasting blood samples were compared in patients with serum content and detect PCT and CRP the positive rate.Results Observer Group in serum PCT positive rate of 92.5%,the average content of PCT (6.31±1.32)ng/ml,the average content of CRP was (40.31±7.23)mg/l,were significantly higher than the 5.0%(0.33±0.08)ng/ml and (5.73±1.12)mg/l,the differences were statistically significant( <0.05);but positive rate of CRP in observation group and the control group was not statistically significant( <0.05).Conclusion of PCT has higher specificity and better stability than CRP,PCT combined with CRP can be considered as an important indicator of severe infections in elderly patients with severe infections.
