口腔科综合治疗台水路污染状况及干预效果分析

目的：通过监测了解口腔综合治疗台水路污染状况,探讨消毒方法及消毒频率,为综合治疗台水路污染控制提供依据。方法：在综合治疗台水路系统消毒前和消毒后第1、2、3、4天随机采集综合治疗台的水源水、手机喷水和三用枪出水的水样进行细菌计数和菌种鉴定,每月1次,重复6次。结果：工作中手机喷水与三用枪出水采样监测,两者比较差异有统计学意义（P〈0.05﹚,消毒后第1、2、3天两者比较无统计学意义（P〉0.05﹚,消毒后第4天与第1天两者比较差异有统计学意义（P〈0.05﹚。结论：口腔综合治疗台水路系统污染较严重,500 mg/L含氯消毒液对综合治疗台水路有较好的消毒效果,可常规应用于口腔综合治疗台水路的消毒处理,以降低医院感染的风险。

Analysis of Comprehensive Treatment of Pollution Condition of Dental Unit Water-lines(DUWL)and Intervention Effect in Department of Stomatology

Objective：To explore disinfection method and frequency of disinfection,providing a basis for compre-hensive treatment of pollution condition of dental unit waterlines by monitoring. Methods：The bacteria count and strains were identified by randomly collecting sample water through mobile phone spray and three spray gun. after 1,2,3,4 days for the comprehensive treatment of water system before sterilization and disinfection,once a month for 6 times re-peatedly. Results：The water sample monitoring was completed by both mobile phone spray and three spray gun. Com-paratively,There was statistically significant difference（P〈0. 05）;After the 1st,2nd and 3rd day of disinfection with phone spray and three spray gun,there was no statistically significant difference（P〉0. 05）;after the 4th day of disin-fection ,there was statistically significant difference,compared with the 1st day（P〈0. 05）. Conclusion：500 mg/L chlorine disinfectant for integrated DUWL treatment station is helpful. Serious water system pollution exists in the oral comprehensive treatment. Comprehensive treatment of water disinfection can be used routinely in the integrated DUWL treatment to reduce the risk of infection in the hospitals.
