摘要
目的探究消毒湿巾对牙科综合治疗台物体表面的清洁消毒效果,为科学开展感染防控工作提供理论依据。方法对北京市市属医院25个院区的牙科综合治疗台物体表面分别进行采样,采用快速检测方法,了解其污染程度,使用含有季铵盐成分的一次性消毒湿巾清洁消毒后,评价清洁消毒效果。结果采集牙科综合治疗台物体表面样本共900件,包括被污染后450件和清洁消毒后450件。被污染后物体表面合格率为64.89%,其中痰盂表面合格率(37.33%)低于其他点位。使用消毒湿巾清洁消毒后,牙科综合治疗台物体表面合格率提升至90.00%,患者椅两侧扶手合格率最低(82.67%),操作台面和面板(医生侧)合格率最高(94.67%)。结论消毒湿巾可有效对牙科综合治疗台物体表面进行清洁消毒。医疗机构应加强对牙科综合治疗台清洁消毒流程的优化及管理,重视牙科水路及患者频繁接触点位的清洁消毒。
Objective To investigate the cleaning and disinfection efficacy of disinfectant wipes on the object surfaces of comprehensive dental treatment equipment,and to provide the theoretical evidence for prevention and control nosocomial infection.Methods Object surface samples were collected from dental units across 25 campuses of municipal hospitals in Beijing.Rapid detection methods were employed to assess the level of surface contamination.The cleaning and disinfection efficacy was evaluated after using disposable disinfectant wipes containing quaternary ammonium compounds.Results A total of 900 samples were collected from the comprehensive dental treatment equipment,including 450 samples contaminated by high splash treatment,and 450 samples after cleaning and disinfection.After the high splash treatment,the qualified rate of the contaminated object surfaces was 64.89%,among which the qualified rate of the spittoons(37.33%)was lower than other points.After cleaning and disinfection,the qualified rate of the object surfaces increased to 90.00%,the qualified rate of the patient’s armrests(both sides)was the lowest(82.67%),and the qualified rate of the operating table and panel(doctor’s side)was the highest(94.67%).Conclusion The disinfectant wipes can effectively clean and disinfect the object surfaces of the comprehensive dental treatment equipment.Medical institutions should strengthen the management of the cleaning and disinfection process of comprehensive dental treatment equipment,and pay attention to the dental water lines and high-frequency contact points of patients.
