Flexible nasoendoscope is an important tool in otorhinolaryngology practice. The endoscope needs to be decontaminated prior to use in the next patient. The 2005 ENT-UK guidance for cleaning fibre-optic laryngoscopes stated that the ideal disinfecting agent and process should be effective and have low capital and maintenance costs.
To compare the efficacy and cost-effectiveness of chlorine dioxide wipes versus automated washer, for decontamination of flexible nasendoscopes.
A sequential cohort, in vitro study was performed to test the efficacy of chlorine dioxide wipes and automated washer. Costs were also calculated.
After deliberate bacterial contamination of the nasendoscope and subsequent decontamination, swab samples from the endoscope showed Staphylococcus epidermidis growth in 2 per cent (1/50 swabs) of the chlorine dioxide wipe group and in 28 per cent (14/50 swabs) of the automated washer group (p = 0.00). Based on a projected 10-year cost calculation, the automated washer was cheaper.
Further studies are required to test whether these results are replicable. A similar study should be performed using real patients, to check the significance of improper decontamination.
可弯曲鼻内镜是耳鼻咽喉科临床的重要工具。在下一位患者使用前，内镜需要进行消毒。2005年英国耳鼻喉科协会关于纤维喉镜清洁的指南指出，理想的消毒剂和消毒流程应有效且资金和维护成本低。
比较二氧化氯擦拭布与自动清洗机对可弯曲鼻内镜消毒的效果和成本效益。
进行了一项序贯队列体外研究，以测试二氧化氯擦拭布和自动清洗机的效果，并计算成本。
故意对鼻内镜进行细菌污染并随后消毒后，内镜的拭子样本显示，二氧化氯擦拭布组有2%（1/50个拭子）出现表皮葡萄球菌生长，自动清洗机组有28%（14/50个拭子）出现表皮葡萄球菌生长（p = 0.00）。基于预计的10年成本计算，自动清洗机更便宜。
需要进一步研究以测试这些结果是否可重复。应使用真实患者进行类似研究，以检查消毒不当的影响。
