Clinical effect of disinfection by hypochlorous acid disinfectant in the water channel of oral comprehensive treatment table
口腔综合治疗台水路通过次氯酸消毒液消毒的临床效果

摘要

目的 分析口腔综合治疗台水路通过次氯酸消毒液消毒后实际情况。方法 选择我院2018年前6台口腔综合治疗台水路没有装次氯酸消毒设备和2018年后6台口腔综合治疗台水路装次氯酸消毒设备，将2018年前6台口腔综合治疗台水路没有装次氯酸消毒设备设置为对照组，将2018年后6台口腔综合治疗台水路装次氯酸消毒设备设置为观察组，对比两组总菌落数、微生物种类以及条件致病菌。结果 观察组实施装次氯酸消毒设备后没有发现总菌落数明显减少，（P<0.05）为差异显著，有统计学意义。对照组检出铜绿假单胞菌，大肠埃希氏菌、嗜肺军团菌。水样检出为荧光假单胞、支气管败血性博代氏杆菌、尿道气球菌、醋酸钙鲍氏不动杆菌、鲁氏／琼氏不动杆菌、皮氏／汤氏罗尔斯顿菌、产碱杆菌。观察组检出施氏假单胞菌、泡囊短波单胞菌。铜绿假单胞菌、大肠埃希氏菌、嗜肺军团菌未检出。结论 口腔综合治疗台水路存在微生物污染，感染风险较高。 通过次氯酸消毒液消毒能够降低微生物，降低医院感染风险，值得临床重视。

Abstract

Objective: To analyze the actual situation of oral comprehensive treatment table water channel after disinfection by hypochlorous acid disinfectant.
Methods: Select the first 6 oral comprehensive treatment tables in our hospital in 2018 without hypochlorous acid disinfection equipment in the waterway and 6 oral comprehensive treatment tables with hypochlorous acid disinfection equipment in the waterway after 2018. The first 6 oral comprehensive treatment tables in 2018 were selected. The waterway without hypochlorous acid disinfection equipment was set as the control group. After 2018, the waterway of the 6 dental comprehensive treatment stations equipped with hypochlorous acid disinfection equipment was set as the observation group, and the total number of colonies, microbial species and opportunistic pathogens were compared between the two groups.
Results: The observation group did not find that the total number of colonies decreased significantly after the installation of hypochlorous acid disinfection equipment, and the difference was significant (P<0.05), which was statistically significant. Pseudomonas aeruginosa, Escherichia coli and Legionella pneumophila were detected in the control group. The water samples were detected as Pseudomonas fluorescens, Bordetella bronchiseptica, Balloon urethra, Acinetobacter calcium acetate baumannii, Acinetobacter rouge/A. Alcaligenes. Pseudomonas stutzeri and Brevimonas vesicularis were detected in the observation group. Pseudomonas aeruginosa, Escherichia coli, and Legionella pneumophila were not detected.
Conclusion  : There is microbial contamination in the waterway of the oral comprehensive treatment table, and the risk of infection is high. Disinfection with hypochlorous acid disinfectant can reduce microorganisms and reduce the risk of nosocomial infection, which is worthy of clinical attention.
