目的观察冬季雾霾天气下手术室空气净化的效果。方法分别于冬季晴朗天气和雾霾天气对手术室空气净化情况进行分析,比较两种天气下细菌监测情况。结果雾霾天气手术区、周边区以及进风口的菌落数均略有提高,但均符合国家标准,差异无统计学差异(P>0.05);两种天气情况下检出细菌分布无明显差异(P>0.05),主要菌株均为微球菌属;晴朗天气手术室空气合格率为93.3%,雾霾天气合格率为86.7%,无明显差异(P>0.05)。结论雾霾天气会对手术室空气质量情况造成轻微影响,略微提高空气中的沉降菌落数,但均在规定的标准内,对手术室空气质量影响不大。
Objective To observe the effect of air purification in operating room under winter haze weather. Methods The air purification in the operating room was analyzed in sunny and haze days in winter respectively, and the bacterial monitoring in two kinds of weather was compared. Results There was a slight increase in the number of colonies in the operation area, surrounding area and air inlet of the haze weather, but all of them were in line with the national standards with no significant difference (P> 0.05). There was no significant difference in the distribution of bacteria detected in the two weather conditions P> 0.05). The main strains were Micrococcus. The air pass rate in operating room was 93.3% in sunny weather and 86.7% in hazy weather with no significant difference (P> 0.05). Conclusion The hazy weather will slightly affect the air quality in the operating room and slightly increase the number of colonies in the air. However, it is within the prescribed standard and has little effect on the air quality in the operating room.
