筛查就有提醒功能?那如果不是传染病患者就可以不做防护了吗?
世界胃肠病学会实践指南-内窥镜消毒
There have been concerns regarding the transmission of hepatitis C virus (HCV) following an instance reported in 1997 . Transmission of viral infection occurred because of failure to brush the biopsy channel, failure to clean ultrasonically and steam sterilise reusable biopsy forceps, inadequate exposure to the liquid chemical germicide. Adherence to current reprocessing guidelines effectively eliminates the risk of HCV transmission from endoscopy .In fact the hepatitis viruses are among the micro-organisms most sensitive to disinfectants in current use.
Glutaraldehyde based products have historically been the most commonly used disinfectants in endoscopy units worldwide. Most reports of transmission of bacteria such as pathogenic E. coli Salmonella, Pseudomonas, Enterobacter and Serratia spp. predate not only the introduction of glutaraldehyde for disinfection but also the practice of using fully immersible endoscopes and exposing all working channels to the decontamination process .
坚持处理准则能有效地消除肝炎病毒通过内镜传播的风险。事实上,肝炎病毒等微生物对戊二醛是敏感的。
所以我方认为:内镜检查前不需要筛查传染病四项。
