目的了解纤维支气管镜的结核杆菌污染及其消毒措施。方法采用结核杆菌培养技术和现场抽样监测方法对160支纤维气管镜进行了调查。结果从使用后的支气管镜表面和活检钳各检出结核杆菌1例阳性,阳性率为1.25%。镜钳孔、毛刷、内腔洗脱液和消毒用20 g/L戊二醛消毒剂均未检出结核杆菌。所调查的160支纤维支气管镜均采用五槽法清洗消毒,经20 g/L戊二醛消毒剂浸泡消毒45 m in,消毒效果合格率达到98.75%。结论本医院结核病所使用的纤维支气管镜存在结核杆菌污染,在规范清洗消毒操作条件下,支气管镜结核菌污染可得到有效控制。
Objective To understand the contamination of Mycobacterium tuberculosis in bronchoscope and its disinfection measures. Methods A total of 160 fiberoptic bronchoscopes were investigated using Mycobacterium tuberculosis culture technique and on-site sampling and monitoring methods. Results One case of Mycobacterium tuberculosis was detected from the surface of the bronchoscope and biopsy forceps after use. The positive rate was 1.25%. Mummy stool, brush, lumen eluent and disinfection with 20 g / L glutaraldehyde disinfectant were not detected Mycobacterium tuberculosis. The investigation of the 160 bronchoscope were used five tank cleaning disinfection, soaked with 20 g / L glutaraldehyde disinfectant 45 m in, the disinfection pass rate of 98.75%. Conclusion Mycobacterium tuberculosis is found in the bronchoscope used in our hospital for tuberculosis. The pollution of bronchosclerotic bacterium can be effectively controlled under the standard cleaning and disinfecting operation conditions.
