目的探寻适当的医院门诊空气质量微生物学评价方法。方法无风晴天气象条件下,用撞击法采集3家三甲综合医院门诊内、外的空气,检测空气菌落总数、溶血葡萄球菌、藤黄微球菌,并对医院门诊大厅内、外空气细菌数量及指标菌在空气细菌所占比例进行对比分析。结果医院门诊大厅内、大厅外人多处空气菌落总数分别为1 281 CFU/m3、1 094 CFU/m3,两者差异无统计学意义;大厅内、大厅外人多处溶血葡萄球菌在空气细菌所占比例分别为4.03%、1.76%,藤黄微球菌分别为3.64%、7.14%,显示大厅内空气污染程度高于大厅外人多处。结论仅以菌落总数为指标,不能判断门诊大厅内、大厅外人多处空气污染程度的差别,而增加溶血葡萄球菌、藤黄微球菌在空气细菌所占比例为指标,可充分显示该差别。
Objective To explore appropriate method of microbiological evaluation of air quality in outpatient clinics. Methods Air-free air was collected from outpatient clinics of three KCR hospitals by impact method in the absence of wind and clear weather. The total number of air colonies, Staphylococcus haemolyticus and Micrococcus luteus were detected. The number of bacteria in the air inside and outside the outpatient hall The proportion of indicator bacteria in airborne bacteria was compared and analyzed. Results The number of airborne colonies outside the hall was 1 281 CFU / m3 and 1 094 CFU / m3, respectively, in the outpatient hall of the hospital. There was no significant difference between the two groups. In the hall, The proportions were 4.03% and 1.76% respectively, Micrococcus luteus were 3.64% and 7.14% respectively, which showed that the indoor air pollution degree in the hall was higher than that in the lobby. Conclusion Only the total number of colonies as an indicator, can not determine the out-patient lobby, outside the hall a number of differences in levels of air pollution, and increase the proportion of Staphylococcus aureus, Micrococcus luteus in air bacteria as an indicator can fully show the difference.
