目的研究纸片法直接采样快速检测皮肤消毒效果的可行性。方法采用纸片直接贴附皮肤采样快速检测皮肤消毒效果的纸片法,同时用标准法棉拭子采样检测法作平行对照比较。结果细菌染菌方法相同,同种试验菌,同种采样检验方法,两种浓度菌悬液,高浓度的染菌回收率低于低浓度的染菌回收率;同种试验菌,同种浓度的菌悬液,两种采样检验方法,纸片法的染菌回收率高于标准法的染菌回收率,经统计学分析差异具有统计学意义(P〈0.05)。结论纸片法的染菌回收率高于标准法,且纸片法直接贴附皮肤采样,操作简便,培养时间短,在皮肤消毒效果的快速检测方面具有很大潜力。
Objective To explore the feasibility of rapid detection of skin disinfection effect with direct sampling paper disk method. Methods The paper disk method by which the samples were sampled from the paper disk attached directly to the skin was used for detecting the skin disinfection effect. The standard method that cotton swab sampling detection method was used as parallel control for comparing the results of the two methods. Results Under the same bacterial contamination operation,with the same kind of test bacterium and the same sampling inspection method,two kinds of bacterial concentration suspension,the recovery rate of bacteria of high concentration was lower than the low concentration; with the same kind of test bacterium and the same kind of bacterial concentration suspension,two kinds of sampling detection methods,the recovery rate of bacteria of the paper disk method was higher than the standard method,and the difference of the two methods was statistically significant( P〈0. 05). Conclusion The recovery rate of bacteria of the paper disk method is higher than the standard method. The operation of the paper disk method is simple and the culture time is shorter than the standard method,which suggests that the paper disk method is great potential in the rapid examination of skin disinfection effect.
