快速手消毒剂使用时间及其消毒效果观察

目的探讨快速手消毒剂开启后不同时间的染菌量及其消毒效果，为临床快速手消毒剂的有效使用提供指导。方法在同一科室同一时间开启使用3瓶快速手消毒剂，并在开启使用第1天、10天、20天、30天、40天时各随机取15份样本行细菌培养，同时对使用相应消毒剂消毒的手进行采样培养。结果在开启使用第1天的快速手消毒剂中，细菌量最高者仅为11 CFU/mL；使用该消毒剂消毒的手细菌量最高者也仅为6 CFU/cm2。但随着开启时间的延长，快速手消毒剂及用其消毒后手的细菌量均明显增加，至第30 d时分别达93.1 CFU/mL和9.45 CFU/cm2。结论快速手消毒剂应在开启后30 d内使用；对人员少的科室，建议使用小包装的快速手消毒剂，避免浪费和污染。

The action time and disinfectant efficacy of rapid hand disinfectant

Objective To evaluate the bacteria load and disinfectant efficacy after the opening of rapid hand disinfectant , so as to provide reference for the effective use of rapid hand disinfectant in clinic. Methods Three bottles of rapid hand disinfectant in the same department and at the same time were opened for using, 15 samples of these disinfectant were randoraly taken at the 1st, 10th, 20th, 30th, and 40th day of opening for bacterial culture, and hand samples disinfected with disinfectant were also taken for bacterial culture. Results At the 1st day of the opening , the highest bacterial count in disinfectant and disinfected hands were 11 CFU/mL and 6 CFU/cm^2 respectively, but with the prolonged duration of opening of disinfectant , bacterial count in disinfectant and hands increased obviously, which were up to 93.1 CFU/mL and 9. 45 CFU/cm^2 respectively. Conclusion Rapid hand disinfectant should be used within 30 days after opening; for the department without enough staffs, small-packaged rapid hand disinfectant is suggested to avoid waste and contamination.
