摘要
分别采用臭氧及甲醛熏蒸协同紫外线照射对手术室、换药室空气消毒。结果显示：用两种方法行手术室空气消毒后，空气细菌培养菌落数有显著性差异（Ｐ＜０．０５）；用两种方法行换药室空气消毒后，空气细菌培养菌落数无显著性差异（Ｐ＞０．０５）。表明：臭氧空气消毒穿透力强，消毒彻底，操作简便易行，可取代甲醛协同紫外线消毒，尤其适用于较大空间。
Comparison of the effects of air disinfection with ozone(method 1)and with formaldehyde plus ultraviolet(method 2) was made in operative and dressing rooms.Results showed there was statistically significant difference between the two methods for the operative room(P<0.05),but no difference for the dressing room(P>0.05),suggesting that the ozone has powerful penetration,makes the operation simple,and is suitable for the larger room.
