目的探讨高压水/气枪用于内镜清洗操作对供应室清洗间空气质量的影响,为采取有效防护措施提供依据。方法采用平皿沉降法对中心供应室内镜清洗间进行操作前后室内空气细菌含量采样监测;同时观察层流净化设施的空气净化作用。结果中心供应室清洗间层流空气净化设备(30万级)未开启和开启状态,应用高压水/气枪清洗内镜操作前、后(即刻)空气细菌含量比较差异有统计学意义(P<0.05);但层流空气净化设备开启状态时,应用高压水/气枪清洗内镜操作后空气细菌含量均控制在≤500CFU/m3范围内,即达到了《医院消毒卫生标准》中规定的Ⅲ类环境标准。结论高压水/气枪用于内镜清洗操作后对供应室清洗间空气质量有一定影响,工作人员应加强防护;空气层流净化设备对供应室空气净化效果显著、可靠。
Objective To investigate the effect of high pressure water / air gun on the air quality of the cleaning room during the endoscope cleaning, and provide the basis for effective protective measures. Methods The plate sedimentation method was used to monitor the bacterial contents of indoor air before and after the operation of the central supply room, and the air purification of laminar flow purification facilities was also observed. Results There was significant difference in bacteria content in the air before and after the endoscopic operation with high pressure water / air gun when the laminar flow air purification equipment (300,000 level) in the center supply room cleaning room was not opened and opened (P <0.05 ); However, when the laminar air purifying equipment is turned on, the airborne bacteria content after the endoscopic operation of high pressure water / air gun cleaning is controlled to be within the range of ≤500 CFU / m3, that is, the type III environment as defined in the “Sanitation Standard for Hospital Disinfection” standard. Conclusion The use of high pressure water / air gun for cleaning the air in the supply room after the endoscope cleaning operation should be strengthened, and the staff should strengthen the protection. Air laminar purification equipment has obvious and reliable air purification effect on the supply room.
