  • Experimental study on silicone hand disinfection by a touchable non-thermal plasma

    In this study, silicone hand was disinfected by homemade touchable non-thermal plasma to simulate and evaluate its feasibility of application on human hand. Experimental results showed that there was no significant difference whenEscherichia coli (E. coli),Staphylococcus aureus (S. au),Staphylococcus albus (S. al), andPseudomonas aeruginosa (P. ae) were loaded on the silicone hand surface and treated with plasma. The efficiency of plasma disinfection was higher when the treatment time was prolonged or initial bacterial density was lower. When initial bacterial number was 1.0×106–1.0×107 CFU, the plasma disinfection process mainly occured in the first 5 s and more than 99% of bacteria could be disinfected. This study can provide guidelines for the development of a new plasma device for human hand disinfection.

  • Disinfection effect and cost analysis of three different sanitary hand disinfection methods

    ObjectiveTo explore a better hygienic hand disinfection method to improve hand hygiene compliance, by evaluating and comparing the disinfection effects and the economic and time cost expenditures of three different types of hygienic hand disinfection methods.MethodsFrom March to July 2016, patients undergoing blood collection were randomly divided into three groups, and five blood collection nurses used one different type of hygienic hand disinfection method in each group when performing blood collection operation on the patients, including: direct hygienic hand disinfection (group A); wearing gloves, and doing hygienic hand disinfection without putting off gloves (group B); and changing gloves for each patient, and doing hygienic hand disinfection after putting off gloves (group C). Two hundred and ten specimens of the nurses’ hands or gloves surface after hand hygiene were collected from each group for the comparison of hygienic hand disinfection effect, and the differences in economic cost and time cost were compared.ResultsThe passing rates of the disinfection effect of the three different types of sanitary hand disinfection methods were all 100%. The economic cost of group A, B, and C was 9.66, 21.98, and 185.66 yuan, respectively, and the time cost of group A, B, and C was 5 250, 6 860, and 14 700 seconds, respectively. No sharp injury occurred.ConclusionSince direct hygienic hand disinfection does not implement the standard prevention principle, the method of wearing gloves and doing hygienic hand disinfection without putting off gloves is the best in the three different hygienic hand disinfection methods, which not only has the same disinfection effect, but also can save economic cost and time cost, which may improve the medical personnel’s hand hygiene compliance.
