Abstract

BACKGROUND

We show that disinfection using the automatic endoscopic reprocessor is not complete and propose a method for high-grade disinfection of endoscopes.

METHODS

We used an automatic endoscopic reprocessor, Pyser System 83, and 2% glutaraldehyde. After each endoscopic procedure, the endoscopes were divided into three groups. Endoscopes in group A were washed only by the reprocessor. Group B endoscopes were washed by the reprocessor after the connectors were soaked in glutaraldehyde for 5 minutes. The channels, valves, connecting sections of group C endoscopes, and the connectors of the machine were sprayed with glutaraldehyde before machine-washing. Swabs were taken from all 13 parts of each endoscope and machine for microbiologic culture.

RESULTS

Six endoscopes were positive, cumulatively, for bacterial contamination in group A. Among group B endoscopes, one remained contaminated. No endoscope was positive in group C. The difference between group A and C was statistically significant (p < .05).

CONCLUSIONS

Machine washing by automatic endoscopic reprocessors may not achieve complete disinfection. Additional procedures are necessary. High-grade disinfection of the connectors is critical. Disinfection of the interface between the connectors is important.

摘要

背景

我们发现使用自动内镜清洗消毒机进行的消毒并不彻底，并提出了一种对内镜进行高水平消毒的方法。

方法

我们使用了一台自动内镜清洗消毒机，Pyser System 83，以及2%的戊二醛。每次内镜检查后，将内镜分为三组。A组内镜仅由清洗消毒机进行清洗。B组内镜在连接器浸泡于戊二醛5分钟后由清洗消毒机进行清洗。C组内镜在机器清洗前，对其通道、阀门、连接部位以及机器的连接器喷洒戊二醛。从每台内镜和机器的所有13个部位采集拭子进行微生物培养。
