对儿科门诊和病房医生的听诊器进行整群抽样细菌学调查,同时进行了两种消毒液消毒后的细菌学监测对比。结果显示,消毒前的听诊器表面细菌计数83.33％超标,甚至致病性金黄色葡萄球菌占3％。经1:500山花消毒液及75％酒精消毒后,细菌计数全部达标,28份取样细菌仅为2cfu/cm~2,经X~2检验P<0.01。菌种在消毒前8种,消毒后降至1种,相差非常显著。提示,听诊器的污染不可忽视,以75％的酒精或1:500山花消毒液消毒,是预防院内交叉感染的重要措施。
Cluster pedigree bacteriological survey was conducted on pediatric outpatient and ward stethoscopes, along with bacteriological monitoring of two disinfectant solutions. The results showed that the sterilizing surface of the stethoscope before the bacteria count 83.33% exceeded, and even pathogenic Staphylococcus aureus accounted for 3%. After disinfection of 1: 500 mountain flower antiseptic solution and 75% alcohol, all the bacteria counts reached the standard, 28 sampling bacteria was only 2 cfu / cm ~ 2, P <0.01 by X ~ 2 test. Bacteria in the first eight kinds of disinfection, disinfection dropped to one species, the difference is very significant. Tip, the stethoscope pollution can not be ignored, with 75% alcohol or 1: 500 Shanhua disinfectant disinfection, is an important measure to prevent cross-infection in the hospital.
