【摘要】：目的探讨HRCT在儿童麻疹肺炎中的应用。方法搜集59例儿童麻疹肺炎患儿的CT资料。根据临床症状及体征分为普通组(n=42)及重症组(n=17),比较两组间HRCT表现差异和患者血清降钙素原(PCT)水平的差异。采用SPSS 17.0软件,对两组病例的HRCT表现差异采用χ2检验,PCT数值的差异采用独立样本t检验。结果 HRCT表现:普通组以肺间质改变为主(36/42例),与重症组(5/17例)相比,差异有显著统计学意义(χ2=18.095,P0.001);重症组以肺实质改变为主(16/17例),与普通组(13/42例)相比,差异有显著统计学意义(χ2=19.391,P0.001)。其中重症组实变分布范围≥3个肺叶,精确概率P0.001。患者血清PCT水平,普通组平均为(5.78±1.05)ng/ml,重症组平均(16.02±6.26)ng/ml,两组间差异有统计学意义(t=10.53,P0.01)。结论HRCT在儿童麻疹肺炎的诊断中有重要价值。
[Abstract]:Objective to explore the application of HRCT in children with measles pneumonia. Methods CT data of 59 children with measles pneumonia were collected. According to the clinical symptoms and signs, the patients were divided into two groups: normal group (n = 42) and severe group (n = 17). The difference of HRCT and the level of serum procalcitonin (PCT) were compared between the two groups. Using SPSS 17.0 software, 蠂 2 test and independent sample t test were used to test the difference of HRCT performance and PCT value between the two groups. Results HRCT: pulmonary interstitial changes were predominant in the normal group (36 / 42 cases), and the difference was statistically significant compared with the severe group (5 / 17 cases) (蠂 2 / 18.095 P 0.001). Pulmonary parenchyma was the main change in the severe group (16 / 17 cases), which was significantly different from that in the common group (13 / 42 cases) (蠂 ~ 219.391g / P 0.001). In severe group, the distribution range of solid change was more than 3 lobes, and the exact probability was P0.001. The serum PCT level of the patients was (5.78 卤1.05) ng/ml, and (16.02 卤6.26) ng/ml, respectively. There was significant difference between the two groups (t = 10.53, P 0.01). Conclusion HRCT is of great value in the diagnosis of measles pneumonia in children.
