Abstract:
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 level Ⅲ or level Ⅱ operating 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 level Ⅲ or level Ⅱ operating 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.
