污染的灌插头,而不是内镜,在囊镜检查期间导致了Pseudomonas aeruginosa的爆发. 这凸显了辅助设备在感染传播中的风险,以及需要更新再加工指南的需要.
科学领域:
- 感染控制 感染控制
- 微生物学 微生物学
- 医疗设备再加工 医疗设备再加工
背景情况:
- 灵活内镜是已知的感染载体,但灌插头等辅助设备往往被忽视.
- 在柔性内镜中使用的灌插头存在潜在的病原体传播风险.
- 这项研究调查了与受污染的囊镜灌插头有关的特定疫情.
研究的目的:
- 报告与囊镜相关的Pseudomonas aeruginosa感染疫情.
- 为了确定感染的来源,专注于辅助内镜设备.
- 评估灌插头在医疗保健相关感染中的作用.
主要方法:
- 审查实验室,临床和污染清除单位记录.
- 检查消毒装置的审计和对囊囊镜和灌插头进行污染的评估.
- 变量核酸合重复 (VNTR) 类型化Pseudomonas aeruginosa分离物以确认爆发链接.
主要成果:
- 从灌插头中分离了Pseudomonas aeruginosa菌株,但不是从柔性囊泡镜中分离出来的.
- 确定了15例确诊感染,包括细菌病和尿路感染.
- 重加工故障,可能是由于插头未拆卸和不兼容的制造商说明造成的.
结论:
- 辅助内镜设备可以成为感染爆发的重要载体.
- 疫情调查应仔细考虑所有相关设备.
- 制造商对辅助器械的再加工说明需要仔细审查是否与临床实践兼容.
