不同痰标本留取方法对痰培养结果的影响

Influence of different phlegm collection methods on culture result

目的探讨两种不同痰标本留取方法对痰培养结果的影响。方法2007年2—8月我院收治慢性阻塞性肺疾病(COPD)急性加重患者60例,分为实验组和照组各30例。实验组在使用抗生素前将生理盐水6 mL与10%的氯化钠4 mL配制成4%的高渗盐水,以氧气雾化吸入10 min诱导漱口后,留取痰于灭菌塑料容器内,加盖立即送检;对照组在使用抗生素前清水漱口后留取痰于灭菌塑料容器内,加盖立即送检。观察两组标本留取的合格率。结果实验组标本合格率76.7%,对照组46.7%,两组比较差异有统计学意义。结论以诱导方法留取痰标本能有效提高痰标本的合格率,有助于提高疾病诊断的准确率。

Objective To compare the influences of conventional phlegm collection method and inducing collection method. Methods Sixty in-patients with chronic obstructive pulmonary disease （COPD） in the acute stage of exacerbation from February to August 2007 were divided into control group （ n = 30, using conventional phlegm collection method） and experimental group （n = 30, using inducing phlegm collection method）. Take the first phlegm from the patients by two methods, and send phlegm specimens for culture. The qualification rate of phlegm specimen was analysed. Results The qualification rate of phlegm specimen was 76. 7% in experimental group, differently from that in the control group （46.7 % ）. Conclusion The inducing phlegm collection method can effectively enhance the qualification rate of phlegm specimen.
