Randomized Controlled TrialPopulation kinetics of the skin flora on gloved hands following surgical hand disinfection with 3 propanol-based hand rubs: a prospective, randomized, double-blind trial.
To study the bacterial population kinetics on gloved hands following hand treatment with 3 optically indistinguishable, alcohol-based surgical hand rubs, with and without supplements to delay bacterial regrowth. ⋯ With respect to the rapid and dramatic antibacterial action of suitable alcohols at high concentrations and with appropriate neutralizers, the contribution of supplements to the delay of bacterial regrowth on gloved hands appears rather minor, if a product only exerts an immediate effect equivalent to that of the reference disinfection procedure described in EN 12791.

Randomized Controlled Trial Comparative StudyInfluence of rings on the efficacy of hand sanitization and residual bacterial contamination.
Previous studies, conducted before widespread use of scrubless, alcohol-based hand sanitizers, demonstrated increased residual bacterial counts after hand hygiene on hands with jewelry. ⋯ The presence of rings does not negatively impact the effectiveness of alcohol-based hand sanitizers. Use of waterless alcohol-chlorhexidine lotion resulted in the lowest bacterial count.
