目的探究影响痰标本涂阳培阴结果的因素。方法对1 191份涂阳痰标本进行培养,从痰检阳性级别、患者就诊服药情况、标本保存时间进行统计分析。结果 1 191份涂阳痰标本的涂阳培阴率为20.07%,镜检报告级别≤8条、1+、2+、3+、4+痰标本的涂阳培阴率分别为37.50%、26.06%、22.06%、14.81%、8.08%,镜检级别越低涂阳培阴率越高,4+痰标本涂阳培阴率与≤8条、1+、2+、3+相比,差异有统计学意义(P<0.05)。痰标本保存时间≤3 d、3 d~7 d、>7 d的涂阳培阴率分别为14.75%、39.93%、45.95%,≤3 d与3 d~7 d及>7 d的痰标本的涂阳培阴率比较,差异有统计学意义(P<0.05)。结论痰培养标本的选择、患者就诊治疗史、标本保存时间都直接影响到痰培养结果。
Objective To explore the factors influencing smear positive result of sputum in sputum. Methods A total of 1 191 sputum smear positive smear specimens were cultured. The positive rates of sputum smear test, patient medication, and specimen storage time were statistically analyzed. Results The masculine smear rates of smear-positive sputum samples from 1 191 smears were 20.07%, the microscopic examination grade was ≤8, and smear-negative smears rates of sputum samples from 1 +, 2 +, 3 +, 4 + were 37.50% 26.06%, 22.06%, 14.81% and 8.08%. The lower the grade of smear was, the higher the smear positive rate was, and the smear positive rate of 4 + sputum specimens was less than 8, 1 +, 2 +, 3 + The difference was statistically significant (P <0.05). The smear-positive rates of sputum specimens with sputum specimens stored for 3 days, 3 days to 7 days, and 7 days were 14.75%, 39.93%, 45.95%, 3 days to 7 days and> 7 days The smear positive rate of Pei Yin, the difference was statistically significant (P <0.05). Conclusion The selection of sputum culture samples, the history of patient treatment and the specimen preservation time all directly affect the sputum culture results.
