目的分析肺炎患儿痰标本采集时机对痰细菌学检验的影响。方法选择2014年5月至2016年5月至我院就诊的肺炎患儿220例作为本次的研究对象,依照随机分组法分为两组,每组患儿均占据110例。其中常规组患儿在入院后即刻采取痰液标本,实验组患儿在第2天晨起空腹状态下采集痰标本进行细菌学检查,对比两组患儿的细菌培养阳性率。结果实验组合格率为53.64%,常规组合格率为36.36%,P<0.05;实验组细菌培养阳性率为60.91%,常规组细菌培养阳性率为45.45%,比较组间数据差异显著,P<0.05。结论在清晨空腹状态下采集肺炎患儿的痰标本进行痰细菌学检验的临床价值显著,可进一步提高检验阳性率,有利于临床合理用药。
Objective To analyze the influence of sputum specimen collection timing on sputum bacteriological examination in children with pneumonia. Methods A total of 220 children with pneumonia who were admitted to our hospital from May 2014 to May 2016 were selected as the study subjects and divided into two groups according to randomization method. Each group of children accounted for 110 cases. The sputum samples were taken from the routine group immediately after admission. The sputum samples were collected from the experimental group in the fasting state on the second day for bacteriological examination. The positive rates of bacterial culture in the two groups were compared. Results The passing rate of the experimental group was 53.64%, the passing rate of the conventional group was 36.36%, P <0.05. The positive rate of bacterial culture in the experimental group was 60.91%, the positive rate of the bacterial culture in the conventional group was 45.45%, the difference between the two groups was significant (P < 0.05. Conclusions The clinical value of sputum samples from children with pneumonia collected in the early morning fasting state for sputum bacteriological examination is significant, which can further increase the positive rate of test and is beneficial to the clinical rational use of drugs.
