摘　　要：目的了解使用一次性鞋套对重症医学科(ICU)空气细菌培养结果的影响。方法根据《医院消毒卫生标准》(GB15982-2012)及《医疗机构消毒技术规范》(WS/T367-2012)规定的方法,连续15 d对ICU使用一次性鞋套和未使用一次性鞋套时的空气细菌菌落总数进行测定,对细菌培养结果进行分析。结果使用一次性鞋套与未使用一次性鞋套ICU患者数量、探视人员数量及温/湿度比较,差异均无统计学意义(均P>0.05)。使用一次性鞋套时ICU空气细菌菌落总数为[中位数±四分位数间距:(1.20±2.20)CFU/15 min·Φ9 cm平皿],高于未使用一次性鞋套时[中位数±四分位数间距:(0.60±1.10)CFU/15 min·Φ9 cm平皿],差异有统计学意义(P<0.05);未使用一次性鞋套时空气细菌培养合格率高于使用一次性鞋套时(96.67%vs 86.67%),差异有统计学意义(P<0.05)。结论使用一次性鞋套不能改善ICU空气质量。Objective To understand effect of application of disposable shoe covers on the culture result of air- borne bacteria in intensive care unit （ICU）. Methods According to Hygienic standards for disinfection in hospi- tals （GB 15982 - 2012） and Technical standards for disinfection in medical institutions （WS/T 367 - 2012）, the col- ony forming units of bacteria in ICU air were detected for 15 consecutive days when disposable shoe covers were used and unused, bacterial culture results were analyzed. Results The number of patients, number of visitors, temperature, and humidity in ICU when disposable shoe covers were used and unused were not significantly differ- ent （all P〉O. 05）. The total number of bacterial colonies in ICU air when using disposable shoe covers was （median ± interquartile range： [1.20 ± 2.20] CFU/15 min. Φ9 cm. plate）, which was significantly higher than air when disposable shoe covers were not used（median ±interquartile range： [0.60 ±1.10] CFU/15 min. Φ9 cm. plate）, difference was statistically significant（P〈0.05）. The qualified rate of bacterial culture result of air when disposable shoe covers were not used was higher than that when disposable shoe covers were used （96. 670%vs 86.67% P〈 0.05）. Conclusion The use of disposable shoe covers can not improve ICU air quality.
