目的 探讨血常规、血沉、C-反应蛋白水平对小儿急性肺炎的诊断价值。方法 选取2014年1月—2019年12月我院收治的小儿急性肺炎100例作为研究组,同时根据有无发生感染将其分为感染组(26例)与非感染组(74例),另外选择同期在我院检查的健康儿童100例作为对照组。比较感染组与非感染组血常规、血沉、C-反应蛋白水平、感染组与对照组血常规、血沉、C-反应蛋白水平、非感染组与对照组血常规、血沉、C-反应蛋白水平。结果 感染组中性粒细胞百分比、白细胞计数、C-反应蛋白高于非感染组(P＜0.05),两组血沉对比,无明显差异(P＞0.05);感染组中性粒细胞百分比、白细胞计数、C-反应蛋白、血沉高于对照组(P＜0.05);两组中性粒细胞百分比、C-反应蛋白水平相比,无明显差异(P＞0.05),非感染组白细胞计数、血沉高于对照组(P＜0.05)。结论 小儿急性肺炎的诊断中,对小儿的血常规、血沉、C-反应蛋白水平进行检测对诊断疾病非常重要,值得临床使用。

Objective To investigate the diagnostic value of blood routine, erythrocyte sedimentation rate and C-reactive protein level in children with acute pneumonia. Methods A total of 100 cases of acute pneumonia in children admitted to our hospital from January 2014 to December 2019 were selected as the study group. At the same time, they were divided into an infected group (26 cases) and a non-infected group (74 cases) according to the presence or absence of infection. In addition, 100 healthy children examined in our hospital during the same period were selected as the control group. Blood routine examination, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level were compared between infected and non-infected group; in infection and control group blood routine examination, ESR, C-reactive protein level were compared; in non-infection and control group blood routine examination, ESR, C-reactive protein level were compared. Results The percentage of neutrophils, white blood cell count and C-reactive protein in the infected group were higher than those in the non-infected group (P<0.05). There was no significant difference in erythrocyte sedimentation rate between the two groups (P> 0.05). The percentage of neutrophils, leukocyte count, C-reactive protein and erythrocyte sedimentation rate in the infected group were higher than those in the control group (P<0.05). There was no significant difference in the percentage of neutrophils and C-reactive protein levels between the two groups (P> 0.05), and the white blood cell count and erythrocyte sedimentation rate in the non-infected group were higher than those in the control group (P<0.05). Conclusion In the diagnosis of acute pneumonia in children, it is very important to detect the blood routine, erythrocyte sedimentation rate and C-reactive protein level in children, and it is worthy of clinical use.
