目的比较重症监护病房(ICU)不同空气净化方法的效果。方法分别对使用通风方法进行空气净化的胸外科ICU、使用紫外线空气消毒器的神经外科ICU、使用静电吸附式空气消毒器的呼吸内科ICU在2011年9月～2012年8月间的空气环境进行监测。结果空气环境中的细菌数量随月份不同而发生变化,差异具有统计学意义(P<0.05)。胸外科和呼吸内科ICU均有3个月份细菌数量超过Ⅱ类环境标准,神经外科ICU有5个月份超标。三个病房的细菌监测结果,胸外科与呼吸内科之间无统计学意义(P>0.05),但胸外科与神经外科、呼吸内科与神经外科之间均有明显差异(P<0.05)。结论因地制宜的选择空气净化方法,正确的使用消毒设备,是医院感染防控的重要环节。
Objective To compare the effects of different air purification methods in intensive care unit (ICU). Methods Thirty-six patients underwent air-conditioning in the thoracic surgery ICU using the ventilation method, the neurosurgery ICU using the ultraviolet air sterilizer, and the respiratory environment ICU using the electrostatic adsorption type air sterilizer in the air environment from September 2011 to August 2012 monitor. Results The number of bacteria in air environment varied with the month, the difference was statistically significant (P <0.05). Thoracic surgery and respiratory medicine ICU have three months more than the number of bacteria in environmental standards, neurosurgical ICU exceeded five months. There was no significant difference between thoracic and respiratory medicine in the three wards (P> 0.05). However, there was significant difference between thoracic surgery and neurosurgery, respiratory medicine and neurosurgery (P <0.05). Conclusion According to local conditions, the choice of air purification methods, the proper use of disinfection equipment, prevention and control of nosocomial infection is an important part.
