目的 探究整理床单位对病房空气细菌数的影响情况。方法 在外科重症监护病房内,采用平皿沉降检测方法,对整理床单位10例次病房空气细菌数量及菌群构成进行监测,选取床单位整理前5 min、整理后30 min两个时间点,并比较两个时间点的病房空气细菌数量及菌群构成情况。结果 床单位整理前5 min病房空气中的细菌菌落数均不高于200.34 cfu/m³ ,床单位整理后30 min,病房空气中80%菌落数超过200 cfu/m³。床单位整理后30 min的菌落数明显多于床单位整理前5 min,病房中的空气细菌数量在整理床单位后明显上升,但菌群构成情况变化不大。结论 医院护理需要在床单位整理时注意扫床动作、开窗通风、人员活动控制,整理后消毒灭菌等方面进行规范操作,减少整理床单位对病房空气细菌数的不良影响,从而降低院内感染的发生率。

Objective To explore the effect of bed unit making on the number of bacteria in the air of wards. Methods In the surgical intensive care units where 10 bed units were made, the plate settling method was used to monitor and compare the airborne bacterial count and bacterial composition at 5 min before and 30 min after making bed units. Results The number of bacterial colonies in the air of the wards was not higher than 200.34 cfu / m³ at 5 min before the bed units were cleaned in all samples, and exceeded 200 cfu / m³ at 30 min after the bed units were cleaned in 80% samples. The number of bacterial colonies in the bed units after 30 min was significantly higher than that before 5 min of bed unit making. The number of airborne bacteria in the wards increased significantly after bed unit making, but the composition of bacteria did not change much. Conclusion Nurses need to pay attention to bed sweeping, ventilation, personnel activity control during making bed units, as well as subsequent disinfection and sterilization, to reduce the adverse effects of bed unit making on the number of airborne bacteria in the wards, thereby reducing nosocomial infection incidences.
