目的探讨胃镜清洗消毒程序的消毒效果。方法通过人工污染菌和污染的幽门螺杆菌检测方法,评价胃镜清洗消毒程序的消毒效果。结果用于幽门螺杆菌阳性率为39.17%的胃病患者的217支次胃镜在清洗消毒前检出带有幽门螺杆菌有3支,阳性率为1.38%。217支次胃镜清洗消毒处理后未分离到幽门螺杆菌,清洗消毒合格率为100%。清洗消毒后胃镜上污染的金黄色葡萄球菌和大肠埃希菌清除率达到99.99%。结论采取完善的清洗消毒程序,规范地操作,合格率可达到100%。
Objective To investigate the disinfection effect of gastroscope cleaning and disinfection procedures. Methods The disinfection effects of gastroscope cleaning and disinfection procedures were evaluated by detecting artificial contaminated bacteria and contaminated Helicobacter pylori. Results 217 gastroscopes for gastric patients with Helicobacter pylori positive rate of 39.17% were detected with Helicobacter pylori before cleaning and disinfection. The positive rate was 1.38%. 217 Helicobacter pylori bacteria were not isolated after gastroscope cleaning and disinfection, the pass rate of cleaning and disinfection was 100%. Cleansing and disinfection of gastroscopy contaminated Staphylococcus aureus and Escherichia coli clearance rate of 99.99%. Conclusion To improve the cleaning and disinfection procedures, standardized operation, the pass rate can reach 100%.
