2例电子胆道镜环氧乙烷灭菌失败的原因分析及对策

通过对2例电子胆道镜环氧乙烷灭菌失败的相关因素及基本灭菌操作环节进行分析,得出腔镜清洗后残留液体、某些化学消毒剂或待灭菌物品本身材质对环氧乙烷的吸附作用过强、错误的包装、装载方法等是引起电子胆道镜灭菌失败的主要因素.针对上述因素提出相应对策,调整或改进技术操作流程,紧抓质量控制重点监控,通过加强消毒供应中心工作人员相关知识培训,严格执行和落实腔镜清洗、包装、灭菌装载等技术操作规范,提高手术腔镜环氧乙烷灭菌质量,预防院内感染,确保临床手术使用安全.

Reason analysis and the countermeasures on 2 cases of electronic choledochoscope ethylene oxide sterilization failure

ObJective To analyze the reasons and basic steps of thylene oxide sterilization of 2 cases with choledochoscopy sterilization in ethylene oxide failure. We found out that some materials powerful absorbability to ethylene oxide, such as residual Chlorine-containing disinfectant and liquid in the lumens of cleaned choledochoscopy, and the surface layer of choledochoscopy, incorrect packaging, mounting method were all the factors causing sterilization failed. According to above factors that caused sterilization failed, we adJusted and improved technical operations targeted, standardize the management process to strictly enforce endoscopics cleaning, packaging and sterilization mounting, and enhanced staff knowledge of disinfection and trainings to avoid those kind of sterilization failures, and then improved the ethylene oxide sterilization quality of surgical endoscopics, to prevent nosocomial infections, and ensure the safety of clinical surgery.
