目的了解辽宁省部分医院负压洁净手术室的综合技术性能。方法采用平板沉降法和仪器检测法对13间负压洁净手术室综合性能进行了监测。结果所调查的13间负压洁净手术室中只有4间各项指标全部合格。在另外9间负压洁净手术室中,沉降菌浓度合格率为53.8%,尘埃粒子数合格率为46.2%,换气次数合格率为69.2%。静压差、温度、相对湿度、光照度和噪声的合格率依次为76.9%、92.3%、84.6%、92.3%和76.9%。结论辽宁省部分医院负压洁净手术室综合性能指标合格率偏低,其设计和布局存在缺陷。
Objective To understand the comprehensive technical performance of negative pressure clean operating room in some hospitals in Liaoning Province. Methods The comprehensive performance of 13 negative pressure clean operating rooms was monitored by flat plate settlement method and instrumental test. Results Of the 13 negative pressure clean operating rooms surveyed, only 4 indicators were all qualified. In the other 9 negative pressure clean operating rooms, the settling bacteria concentration passing rate was 53.8%, the passing rate of dust particles was 46.2% and the passing rate of ventilation was 69.2%. The passing rates of static pressure, temperature, relative humidity, illumination and noise were 76.9%, 92.3%, 84.6%, 92.3% and 76.9%, respectively. Conclusion The passing rate of the comprehensive performance indexes of negative pressure clean operating room in some hospitals in Liaoning Province is low, and the design and layout of the indexes are defective.
