1、痰标本不同的采集方法影响痰涂片检验合格率相关研究钟海燕邵阳市中西医结合医院湖南邵阳422000【摘要】目的：观察探讨不同痰标木的采集方法对痰涂片检验合格率的影响,总结其临床意义。方法：选取我院2009年4月至20□年4月82例下呼吸道感染的患者，随机分为观察组和对照组，各41例，观察组采取诱导吸痰技术采集，选择在清晨以6ml的牛理盐水配入4ml的10%氯化钠配制成4%的高渗盐水，采取氧气雾化吸入lOmin进行诱导漱口，釆集深咳的痰液标木；对照组采取常规痰液采集，选择在清晨以清水漱口后，采集痰液标木，观察比较两组患者痰标木的留取合格率。结果：观察组合格30
2、例，不合格11例，检出细菌30例，未检出细菌□例；对照组合格20例，不合格21例，检岀细菌21例，未检出细菌20例，两组患者标木的留取合格率及细菌检出率比较存在显著差异（PV0.05）,具有统计学意义。结论：应用诱导吸痰技术采集痰涂片标木，更能真实反映出气道内的炎症反应，标木的检验合格率及细菌检出率皆明显提高，有助于临床尽早诊断和鉴别诊断，为临床提供可靠的实验依据，具有重要的临床意义。【关键词】痰标木；采集方法；痰涂片；合格率；细菌检出率[Abstract]ObjectiveObservationtoexploredifferentsputumsampl
