摘要
目的观察层流净化手术室复合空气消毒效果。方法在设计级别为万级的层流洁净手术间内,用平皿暴露法监测室内自然菌沉降数。分为单纯层流组、层流加紫外线组、层流加鑫永泰喷雾组,分别于层流净化开机1h、开机1h加紫外线照射1.5h、开机1h喷鑫永泰空气消毒剂后10min采样,每周1次,连续20周。结果单纯层流与层流复合紫外线相比较p>0.05,差异无显著性;而单纯层流组、层流加紫外线组2组与层流复合高效空气消毒剂相比较p<0.01,差异有高度显著性。结论使用万级层流净化的手术室,单靠净化达不到空气中菌落数<10cfu/m3的标准,加紫外线照射仍不达标,需结合化学消毒剂喷雾。
Objective: To explore the sterilize effect of laminar flow complex in operating room. Method: plate exposure method were used to measure the volume of nature dissipated bacterium in sterilized laminar flow operating room. Three groups( simple laminar flow, laminar flow plus ultraviolet, laminar flow plus Xinyongtai spray) were assigned, each group were performed with the same manner. Result: there was no obvious deference between simple laminar flow group and laminar flow plus ultraviolet group, while the d...
