目的改进消化内镜及其附件的消毒方法 ,提高消毒效果。方法改进前内镜采用床边三槽消毒法 ,附件采用 2 %戊二醛浸泡 ;改进后建立专用清洗消毒间 ,内镜消毒增加酶洁液刷洗和全浸泡消毒程序 ,附件经戊二醛浸泡后用环氧乙烷熏蒸。比较改进前后细菌及HBsAg阳性率。结果改进前内镜及其附件消毒后细菌阳性率分别为14 .0 %、8.0 % ,HBsAg阳性率分别为 14 .0 %、7.0 % ;改进后细菌及HBsAg阳性率均为 0。改进后消毒效果显著优于改进前 (均P <0 .0 5 )。结论改进方法清洗彻底、消毒时间充分 ,可确保消毒质量
Objective To improve the digestive endoscopy and its accessories disinfection methods to improve disinfection. Methods The improved endoscopic endoscopy was adopted to sterilize the bed with three troughs. The accessories were immersed in 2% glutaraldehyde. After the improvement, a special cleaning and disinfecting room was set up. Endoscope disinfection increased the enzymatic cleansing liquid scrubbing and soaking disinfection procedures. The accessories were soaked in glutaraldehyde After fumigation with ethylene oxide. Compare the positive rate of bacteria and HBsAg before and after improvement. Results The positive rates of bacteriostasis before endoscopy and its attachment were 14.0% and 8.0%, respectively. The positive rates of HBsAg were 14.0% and 7.0% respectively. The positive rates of bacteria and HBsAg were all 0 after the improvement. Improved disinfection was significantly better than before improvement (P <0.05). Conclusion Improved cleaning method thoroughly, disinfection time sufficient to ensure the quality of disinfection
