目的 了解消化内镜清洗消毒现状,选择实用可靠的内镜清洗消毒方法。方法 在北京部分三级甲等医院进行内镜清洗时加或不加酶洁液、2％戊二醛7min消毒效果的测试;并抽查国产自动清洗消毒机的消毒效果。结果 测试部分:使用酶洁液清洗组301例,2％戊二醛浸泡消毒7min,不长菌例数为283例（94、02％）;不使用酶洁液组155例,2％戊二醛浸泡消毒7min,不长菌例数为137例（88.39％）。以清洗消毒后每条胃镜≤20个非致病细菌数为合格标准,使用酶洁液组合格为298例（99.00％）,不使用酶洁液组147例（94.84％）,两组清洗消毒效果差异有统计学意义（P<0.01）。抽查部分:清洗消毒机135例,清洗消毒3 min后不长菌为4例（11.43％）,以清洗消毒后每条胃镜≤20个非致病细菌数作为合格标准,合格为5例（14.29％）;清洗消毒机 Ⅱ29例,清洗消毒 3min,不长菌为2例（6.90％）,合格例数为6例（20.69％）;清洗消毒机Ⅱ20例,更换消毒液,清洗消毒3 min 2次,不长菌为17例（85.00％）,合格例数为18例（90.00％）。结论 内镜使用后各个部分的彻底清洗是保证消毒质量的重要环节,清洗过程中使用酶洁液明显增加了清洁度,在此基础上2％戊二醛浸泡消毒7min可达到内镜消毒标准。目前使用的国产内镜清洗消毒机常规单一的3min和6min的消毒程序达不到
Objective To understand the status of digestive endoscope cleaning and disinfection, choose a practical and reliable endoscopic cleaning and disinfection methods. Methods The disinfection effect of endoscope cleaning with or without enzyme cleaning solution and 2% glutaraldehyde for 7 min was tested in some of the first-class hospitals in Beijing. The disinfection effect of homemade automatic cleaning and disinfecting machine was also tested. RESULTS: In the test part, 301 cases were cleaned with enzymatic cleansing solution and soaked in 2% glutaraldehyde for 7 minutes. There were 283 cases (94,02%) not growing bacteria; 155 cases without enzyme cleansing solution and 2% Aldehyde soak disinfection 7min, no longer the number of bacteria was 137 cases (88.39%). After cleaning and disinfection, the number of non-pathogenic bacteria in each gastroscope ≤ 20 was the qualified standard. The number of eluting enzyme group was 298 (99.00%), 147 cases (94.84%) did not use enzyme cleansing liquid group, The difference was statistically significant (P <0.01). In the spot check, 135 cases were cleaned and disinfected, 4 cases (11.43%) were not grown after cleaning and disinfecting for 3 minutes, and the number of non-pathogenic bacteria ≤20 cases was ≤ 20 cases after cleaning and disinfecting. The qualified rate was 5 cases (14.29 %); Cleaning and disinfecting machineⅡ29 cases, cleaning and disinfecting 3min, not growing bacteria in 2 cases (6.90%), the number of qualified cases was 6 cases (20.69%); cleaning and disinfecting machine Ⅱ20 cases, changing disinfectant, cleaning and disinfection 3 min 2 The number of non-viable bacteria was 17 cases (85.00%), the number of qualified cases was 18 cases (90.00%). Conclusion The thorough cleaning of each part after endoscopic use is an important part of the quality of disinfection. The use of enzyme cleaning solution in the cleaning process obviously increases the cleanliness. On the basis of this, 2% glutaraldehyde disinfection can reach the endoscopic disinfection standard for 7 minutes. Currently used domestic endoscope cleaning and disinfecting machine routine single 3min and 6min disinfection program does not reach
