摘要:

目的评价小儿经鼻腔取痰涂片革兰染色镜检对社区获得性肺炎(CAP)早期诊断的价值。方法对2015年1至3月疑似CAP的患儿经鼻腔取痰样本596例,行细菌培养和革兰染色镜检,比较2种方法的检验结果。结果送检痰样本596例,其中合格样本389例,合格率为65.27%;共培养出病原菌368株,培养阳性率为61.74%(368/596),检出率排在前4位的病原菌依次为卡他莫拉菌、肺炎链球菌、流感嗜血杆菌和金黄色葡萄球菌。痰样本涂片革兰染色镜检与细菌培养结果的符合率为86.24%(514/596),2种方法检测结果差异无统计学意义(P=0.845 0)。结论小儿经鼻腔取痰涂片革兰染色镜检经济、快速,能在早期为CAP的诊断和治疗提供重要信息。

Abstract:

Objective To evaluate the significance of smear Gram staining microscopy of sputum through nose sampling among children for the early diagnosis of community-acquired pneumonia(CAP). Methods From January 2015 to March 2015,596 sputum specimens were collected through nose sampling among children suspected with CAP,and were performed culture and smear Gram staining microscopy. The results of the 2 methods were compared. Results A total of 596 sputum specimens were detected,389 sputum specimens were qualified,and the qualification rate was 65.27%. A total of 368 pathogenic strains were isolated,and the culture positive rate was 61.74% (368/596). Moraxella catarrhalis,Streptococcus pneumoniae, Haemophilus influenzae and Staphylococcus aureuswere the top 4 species of pathogenic strains. The coincidence rate between the results of the 2 methods was 86.24%(514/596),and there was no statistical significance between the 2 methods (P=0.845 0). Conclusions Smear Gram staining microscopy of sputum through nose sampling among children is economical and fast,which could provide important information among children for the early diagnosis and treatment of CAP.
