Surgical hand disinfection with a propanol-based hand rub: equivalence of shorter application times.

The duration of the hand disinfection has an influence on a preparation's efficacy for surgical hand disinfection.

The aim of this study was to evaluate the effectiveness of a propanol-based hand rub at application times of less than 3 minutes. Disinfection with Sterillium was compared to the reference procedure using n-propanol (60%) for 3 minutes in a cross-over design. Sterillium was applied for 3, 2, 1.5 and 1 minute while four other products were tested for 1 minute. Post values, representing immediate and sustained effects, were recorded after hand treatment and gloving for 3 hours. Sterillium outperformed the reference method at 3, 2 and 1.5 minutes for both immediate and sustained effects. However, the immediate effect at 1 minute was slightly lower for Sterillium compared to the reference procedure. However, the sustained effect at 1 minute was not significantly different between the two. None of the other products tested met the requirements for efficacy at 1 minute for both immediate and sustained effects. Overall, the use of 2 x 3 mL Sterillium for a total of 1.5 minutes for surgical hand disinfection was found to be at least as effective as the 3-minute reference disinfection.

Use disinfectants safely. Always read the label and product information before use.
