紫外线和84消毒液联合消毒手术室的效果观察

An Observation on Effects of Disinfection with Ultraviolet and 84 aerosol in the Operation Room

目的 :快速有效地消毒手术室 ,提高手术室利用率。方法 :组 1:紫外线照射 ,组 2 :2 .5 % 84消毒液气溶胶4mL·m 3 喷雾 ,组 3 :紫外线照射加 2 .5 % 84消毒液气溶胶 4mL·m 3 喷雾联合应用。三种方法消毒手术室各 5 0次 ,每次消毒 45min ,比较三种方法的消毒效果。结果 :组 1、组 2、组 3三种方法消毒后 ,空气灭菌率分别为 89.5 % ,88.8% ,94.8% ,物面灭菌率分别为 6 3 % ,6 7% ,87% ,乙肝病毒杀灭率分别为 3 5 % ,80 % ,10 0 % ,消毒不合格率分别占总消毒次数的 2 8% ,16 % ,4%。组 2 ,组 3杀灭乙肝病毒的作用明显优于组 1(P <0 .0 1) ,组 3灭菌作用和消毒效果明显优于组 1、组 2 (P <0 .0 5 )。结论 :二者联用大大提高了杀菌和杀病毒能力 ,优于二者单一使用。可快速高效消毒手术室物面和空间 ,提高手术室利用率。

Objective:To sterilize the operation room rapidly and effectively. Methods:The operation rooms were sterilized with one of the following three methods, respectively: 1. ultraviolet irradiation, 2. 84 disinfectant aerosol nebulization and, 3. the combined use of 84 disinfectant aerosol nebulization and ultraviolet irradiation. Results:There are no significant difference between methods 1 and 2, but the method 3 had stronger effect in sterilization than the methods 1 and 2 (P<0.01), especially with regard to its ability in killing HBV. 84 disinficant is more effective than ultraviolet in getting rid of HBV (P<0.01). Conclusion:It was suggested that the combined use of 84 disinfectant aerosol nebulization and ultraviolet irradiation is more efficient than just using either of the two.
