适当的内镜存储对于感染控制至关重要. 在活性干燥柜中的全垂直悬浮显著降低了内镜通道中的水分和细菌污染.
科学领域:
- 医学微生物学
- 感染控制
- 生物医学工程
背景情况:
- 再处理后内镜通道的不充分干燥会促进微生物生长,造成感染风险.
- 这项研究调查了不同内和方法对残留水分和细菌污染的影响.
研究的目的:
- 评估主动和被动干燥柜与内镜各种存储方法的有效性.
- 评估储存条件对内镜通道中的残留水分和细菌增殖的影响.
主要方法:
- EN-580T内镜存储在主动干燥柜 (TJ-908S,TJ-804S) 和被动干燥柜 (TM-804S) 中.
- 储存配置包括全垂直悬挂,部分悬挂和循环储存.
- 在24小时和48小时后量化了残留水分,并且在储存后评估了细菌污染.
主要成果:
- 与其他条件 (278.5518.7μL) 相比,完全垂直悬挂的TJ-908S机柜的残留水分显著降低 (17.623.9μL).
- 在TJ-908S存储的内镜中的细菌培养显示出最小的生长.
- 用部分或循环方法存储在被动干燥柜 (TM-804S) 和TJ-804S中的内镜显示出更高的细菌数量,其中一些超过100 CFU.
结论:
- 透视器柜的设计和储存方法对干燥效率和细菌生长有重大影响.
- 在活性干燥柜内完全垂直悬浮似乎是减少污染风险和提高内镜再处理结果的最有效方法.

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...
