摘　　要：目的探讨诱导痰对痰涂片阴性肺结核的诊断价值。方法对三次痰涂片阴性肺结核病人采用10%高渗氯化钠吸入20～30分钟或取到20～30ml痰后,立即离心沉渣涂片抗酸染色和结核菌培养。结果83例取痰均成功,涂片抗酸染色阴性50例(60.24%)、(±)12例(14.46%)、(+)13例(15.66%)、(++)8例(9.63%),诱导痰培养阳性36例(43.37%)。结论诱导痰找抗酸杆菌痛苦小、费用低,提高了痰菌检出率,是菌阴肺结核诊断一个有效方法。Objective To evaluate the diagnostic value of the induced sputum in the bacillus-negtive pulmonary tuberculosis (TB).Methods For the patients so called 'negative' in three consecutive sputum smear study, 20~30ml sputum was taken by inhalation of nebulized 10%NaCl and then Zieh1-nelsen staining and bacillus culture were done with the sediment after centrifugal. Results Sputum was induced successfully in all of the 83 cases and smear study was carried out with result of negative (-) in 50 cases (60.24%), suspect (±) in cases (14.46%), positive (+) in 13 cases (15.66%), highly positive (++) in 8 cases (9.63%). Induced sputum culture was positive in 36 cases (43.37%).Conclusion The reexamination of the induced sputum is an easy, low cost, and effective method for the diagnosis of 'bacillus-negtive' TB.
