云南省综合医院洁净手术室综合性能检测结果分析

Analysis of Comprehensive Performance of Clean Operating Rooms in some General Hospitals in Yunnan Province

目的了解云南省综合医院洁净手术室的综合性能,为保障手术室洁净质量提供参考。方法采用现场采样检测方法,对云南省22家医院共125间洁净手术室的尘埃粒子数、温度、相对湿度、静压差、截面风速、换气次数、噪声、照度、沉降菌进行静态检测。采用卡方检验,分别比较分析不同洁净等级、新改建和投入使用≥1年的手术室中各检测指标的合格率。结果 125间洁净手术室尘埃粒子数、温度、相对湿度、静压差、截面风速、换气次数、噪声、照度、沉降菌的合格率分别为92.00%、91.20%、86.40%、83.20%、92.59%、90.82%、86.40%、89.60%、96.00%。Ⅲ级和Ⅱ级洁净手术室悬浮粒子合格率高于Ⅰ级洁净手术室(P<0.05),Ⅲ级洁净手术室噪声合格率高于Ⅱ级和Ⅰ级洁净手术室(P<0.05)。新建或改建手术室的悬浮粒子、温度、相对湿度、静压差、截面风速、换气次数、噪声、照度和沉降菌的合格率高于投入使用≥1 a的手术室(P<0.05)。结论云南省新建或改建洁净手术室合格率较高,但投入使用≥1 a的手术室各项指标检测合格率不容乐观,需加强管理和维护。

Objectives To understand the comprehensive performance of the clean operating rooms in some general hospitals in Yunnan.Methods 125 clean operating rooms in 22 general hospitals were monitored by field sampling.The dust particles,temperature,humidity,the static pressure difference,air velocity,ventilation,noise,illumination and airborne microorganism were tested under static condition.Chi-square test was used to analyze the qualified rates of operating rooms with different cleanliness grades,new renovation and operation for more than 1 year.Results In 125 clean operating rooms,the qualified rates of dust particles,temperature,humidity,the static pressure difference,air velocity,ventilation,noise,illumination and airborne microorganism were 92.00%、91.20%、86.40%、83.20%、92.59%、90.82%、86.40%、89.60%、96.00%,respectively.The qualified rate of dust particles of levelⅢor levelⅡoperating rooms was higher than that of levelⅠoperating rooms(P<0.05).The qualified rate of the noise of levelⅠoperating rooms was higher than that of levelⅢor levelⅡoperating rooms(P<0.05).The qualification rates of comprehensive performance of newly built or rebuilt clean operating rooms were higher than the clean operating rooms which have been used for more than one year(P<0.05).Conclusions Compared with newly built or rebuilt clean operating rooms,the comprehensive performance of clean operating rooms which have been used for more than one year were not satisfying in some general hospitals in Yunnan.Regular maintenance and management should be strengthened.
