Abstract:
Objective To understand environmental quality status of clean operating rooms in municipal hospitals of Xi’an,and provide reference for ensuring the clean quality of operating rooms.Methods On-site specimen collec-tion and detection were conducted to detect and analyze the cleanlinss of air in clean operating rooms in 15 hospital of Xi’an.Results A total of 51 operating rooms were monitored,secondary and tertiary hospitals had 24 and 27 operating rooms respectively;26 were grade-I and 25 were grade-Ⅲ operating rooms.The qualified rates of dust particle≥0.5μm/particle size in grade-I and grade-Ⅲ clean operating rooms were 76.92% and 80.00% respective-ly,≥5μm/ particle size were 73.08% and 88.00% respectively.The qualified rates of dust particle counts in grade-I and grade-Ⅲ clean operating rooms were 61 .54% and 80.00% respectively,difference was not significant(χ2=2.092,P >0.05 ).The qualified rate of dust particle counts in clean operating rooms in tertiary hospitals was significantly higher than secondary hospitals(85.19% vs 58.33%,χ2 =4.600,P <0.05 ).The qualified rates of airborne microbes in operating zone of secondary and tertiary hospitals were 87.50% and 92.59% respectively(P >0.05),in surrounding zone were 95.83% and 92.59% respectively (both P >0.05).Conclusion Dust particle and airborne microbes in some clean operating rooms in municipal hospitals of Xi’an are beyond the standard,supervi-sion and management should be strengthened.
