采用经纤支镜支气管冲洗液及涂片查抗酸杆菌的方法,对67例痰菌阴性肺结核进行检查。结果显示:支气管冲洗液抗酸杆菌检出率79.1%,直接刷片检出率55.2%,两者比较有非常显著性差异(P<0.01);支气管冲洗液+刷片联合检出率91.0%。说明支气管冲洗液查抗酸杆菌对痰菌阴性肺结核是一种简单、实用的诊断技术,支气管冲洗液+刷片联合检查可以提高结核杆菌的检出率。
67 cases of sputum negative pulmonary tuberculosis were examined by means of bronchial bronchial fluid with bronchoscopy and acid-fast bacilli smear. The results showed that the detection rate of acid-fast bacilli in bronchoalveolar lavage fluid was 79.1% and that of direct brushing was 55.2% (P <0.01). The combined detection rate of bronchoalveolar lavage + brush was 91.0% . Description of bronchoalveolar fluid check acid-fast bacilli sputum negative tuberculosis is a simple and practical diagnostic techniques, bronchial wash fluid + brush joint examination can increase the detection rate of Mycobacterium tuberculosis.
