云南省医院洁净手术室综合性能及运行现状监测

Monitoring report on comprehensive performance and operation status of clean operating rooms in hospitals in Yunnan province

目的了解云南省医院洁净手术室的综合性能及运行现状,发现存在的问题,为洁净手术室的科学管理提供依据。方法以《医院洁净手术部建筑技术规范》作为监测和判断标准,于2017年2-5月对云南省34家医院共81间洁净手术室静态条件下的洁净度及微小气候等进行了现场监测。结果不同级别医院手术室内微粒直径≥0.5μm和≥5.0μm两类尘埃粒子数均合格的概率分别为三级医院0.00%、二级医院2.38%;浮游菌合格率分别为三级医院79.49%、二级医院100.00%。相关技术指标的合格率由高到低分别为相对湿度85.19%(69/81)、温度72.84%(59/81)、噪声71.60%(58/81)、照度51.85%(42/81)和静压差45.68%(37/81)。I级洁净手术室截面风速及风速不均匀度β的合格率分别为13.33%(4/30)、33.33%(10/30);II级、III级洁净手术室的换气次数、风速无盲区的合格率分别为72.55%(37/51)、78.43%(40/51)。三级医院和二级医院洁净手术室之间以上指标差异均无统计学意义。结论云南省医院洁净手术室洁净度指标和其余技术指标均未全部合格,特别是尘埃粒子数合格率偏低。应尽快加强各级各类医院相关人员对洁净手术室的使用、管理和维护等相关知识的培训,以加强手术室的日常监督和规范化管理。

OBJECTIVE To understand the comprehensive performance and operation status of clean operating rooms in hospitals in Yunnan province,and to find out the existing problems,so as to provide basis for scientific management of clean operating rooms.METHODS ＂ Architectural technical code for hospital clean operating department＂ was mainly applied to be the monitoring and judgment basis,and a total of 34 hospitals including 81 clean operating rooms in Yunnan province were randomly sampled,and field test was used to monitor the cleanliness and microclimate indicators for the in-using clean operating rooms under static condition from Feb.2017 to May 2017.RESULTS As one of the indicators of cleanliness,the number of dust particle with diameter more than0.5μm or 5.0μm which were both qualified in clean operating rooms were 0.00%for classⅢ hospitals,and 2.38%for classⅡ hospitals.The qualified rates of planktonic bacteria were 79.49% for classⅢ hospitals and 100.00%for classⅡ hospitals,The qualified rate ranking from high to low among all microclimate and other indicators such as differential static pressure indicators were 85.19%（69/81）for relatively humidity,72.84%（59/81）for temperature,71.60%（58/81）for noise intensity,51.85%（58/81）for illumination,and 45.68%（58/81）for differential static pressure.The qualified rates of section wind speed and unevenness of wind speedβin classⅠclean operating rooms were 13.33%（4/30）and 33.33%（10/30）.The qualified rates of ventilation frequency and wind speed without blind zone in classⅡand classⅢclean operating rooms were 72.55%（37/51）and 78.43%（40/51）.There were no significant differences in the above indicators between the class Ⅲ and class Ⅱ hospitals.CONCLUSION The cleanliness indicators and other related technical indicators of clean operating rooms in hospitals in Yunnan province were not all qualified,especially the qualified rate of dust particles was low unexpectedly.For these reasons,we should strengthen the training of relevant knowledge about how to use,manage and maintain the clean operating rooms among related personnel at all levels of hospitals as soon as possible,so as to strengthen the daily supervision and standardized management of clean operating rooms.
