目的:通过观察新烧伤病房启用后不同部位空气细菌含量的变化,明确病区感染控制工作和清洁卫生工作的重点。方法:在新病房的两个楼层内设定采样点30个,选择采用 LWC—I离心式空气微生物采样器进行采样,每个采样点采样3次,结果取3次采样的平均值。采样时间为在新病房启用前和启用4个月后(不使用空调的季节),启用后采样的时段选在夜间患者就寝后1小时。结果:启用前所有采样点的平均菌量399.4 cfu/m~3,启用后空气中的菌量明显增加,平均达2768.7cfu/m~3。第4层病房使用前菌量最高的采样点为护士站、外走廊
Objective: To observe the change of airborne bacteria content in different parts after the new burn ward was opened, and to clarify the focus of disease control and clean-up work. METHODS: Thirty samples were set up on two floors of the new ward. LWC-I centrifugal air samplers were selected for sampling. Each sample was sampled three times and the result was taken as the average of three samples. Sampling time is before the opening of the new ward and 4 months after the start-up (season without air-conditioning). The sampling period after opening is 1 hour after bedtime. Results: The average bacterial count of all sampling sites before the opening was 399.4 cfu / m ~ 3. After opening, the average amount of bacteria in the air increased significantly, reaching an average of 2768.7 cfu / m ~ 3. The fourth floor of the ward before the use of the highest sampling points for the nurses station, outside the corridor
