概括
简短的手动清洗时间 (≤5分钟) 显著增加了十二指镜污染的风险. 加强对再加工的监测可能会降低临床环境中的污染率.
科学领域:
- 感染控制 感染控制
- 医疗设备再加工 医疗设备再加工
- 胃肠病学 胃肠病学
背景情况:
- 十二指镜很容易受到污染,尽管遵守再处理协议.
- 关于当前十二指镜再处理方法的效率存在重大知识差距.
- 鉴定影响十二指镜污染的因素对于患者安全至关重要.
研究的目的:
- 确定导致污染的十二指镜再加工程序中的特定风险因素.
- 评估手工清洗时间,再加工的交付时间和人员因素对污染率的影响.
- 提供基于证据的建议,以提高十二指镜再处理效率.
主要方法:
- 分析了2022年2月至2023年12月期间处理的307台Pentax ED34-i10T2十二指镜的培养物.
- 通过肠道或口腔来源的微生物 (MGO) 的存在来定义污染.
- 用于评估风险因素的物流混合效应建模,包括手动清洗持续时间 (≤5分钟),延迟启动 (>30分钟),干燥时间 (<90分钟),人员频率和储存持续时间 (>7天).
主要成果:
- 18.9%的十二指镜培养 (58/307) 显示MGO污染.
- 手动清洗时间≤5分钟与污染概率的增加显著相关 (aOR:1.61,P=0.01).
- 增加十二指镜的使用与减少污染几率相关 (aOR:0.80,P=0.045),而其他因素没有显著的关联.
结论:
- 手动清洗时间≤5分钟是十二指镜被MGO污染的重要风险因素.
- 与传统假设相反,在本研究中,再加工启动的延迟和不完全干燥没有显示出与污染的显著关联.
- 建议对再处理时间的加强监控进行进一步的研究,以减轻十二指镜污染.

6.6K
Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
