目的　为了解空调器对手术室空气质量的影响。方法　对 12间手术室空气中及空调合叶扇细菌的种类、数量在空调使用前后进行对比和相关分析。结果　手术室空气中和空调合叶扇细菌种类基本一致 ;空气中的细菌数量与赖于空调器的开启 ,呈显著的相关性 (r达到 0 .6 6～ 0 .93 ,P <0 .0 1) ;通过清洗或消毒能明显减少合叶及空气中的细菌含量。结论　空调器的使用显著影响着手术室空气质量 Objective To understand the air conditioner on the operating room air quality. Methods The types and quantities of bacteria in the operating room air and air-conditioners were compared and analyzed before and after air-conditioning. Results The operating room air and air-conditioning fan Ye bacteria basically the same; the number of bacteria in the air depends on the air conditioner on, was significantly correlated (r reached 0.6 6 ~ 0.93, P <0 .0 1); By cleaning or disinfection can significantly reduce the bacterial content of leaves and air. Conclusion The use of air conditioners significantly affects the operating room air quality
