降钙素原、C反应蛋白及白细胞计数鉴别小儿感染性肺炎的意义

Significance of procalcitonin, C-reactive protein and white blood cell count in identifying children with infectious pneumonia

目的探究降钙素原、C反应蛋白及白细胞计数在小儿感染性肺炎的临床鉴别诊断中的意义。方法选取我院2013年10月-2014年4月住院小儿肺炎90例患儿为观察组,选取同期住院的非肺炎小儿54例为对照组,对两组患儿进行降钙素原、C反应蛋白及白细胞计数的检验,并进行比较分析。结果观察组中CRP的（＋）检出率为47.78%,WBC的（＋）检出率为38.87%,PCT的（＋）检出率为91.11%;两组患儿在CRP、WBC、PCT三项检测指标的比较上x2分别为36.5287、16.8201、109.3631,差异有统计学意义（P〈0.05）。结论降钙素原、C反应蛋白及白细胞计数的监测有助于临床上对小儿感染性肺炎的鉴别诊断,对其动态的检测可促进细菌性肺炎的确诊,具有高度的临床使用价值。

Objective To explore significances of differential clinically diagnosis of procalcitonin, C-reactive protein and white blood cell count in children with infectious pneumonia. Methods Ninety children with infantile pneumonia admitted by this hospital from October 2013 to April 2014 were selected into the observation group, 54 patients with pneumonia admitted by this hospital during such period were selected into the control group, calcitonin, procalcitonin, C-reactive protein and white blood cell count tests were applied on patients in two groups, and results were compared and analyzed. Results The（＋） detection rate of CRP in the observation group was 47.78%, the（＋） detection rate of WBC hit 38.87%,（＋）detection rate of PCT hit 91.11%. The comparison x2 in three test index CRP, WBC and PCT hit 36.5287, 16.8201, and 109.3631, P〈0.05 respectively, and the difference was statistically significant. Conclusion The monitoring on procalcitonin, C-reactive protein and white blood cell count is helpful to differential diagnosis on pediatric infectious pneumonia clinically, and dynamic testing is capable of promoting the diagnosis of bacterial pneumonia, being of high value of clinical use.
