Based on findings the most common micro-organism was the negative coagulase staphylococcus (92% of cases), the others were antrococus, kurine, Basilus and E-coli, respectively. All independent variables significantly decreased microorganisms immediately after intervention. Among three groups, the alcohol-based hand rub in comparison with two other methods showed more reduction, while two kinds of soaps showed no significant difference. Regarding this fact the on of the most important ways of transferring nosocomical infections is personnel’s hands, as the alcohol- based hand rub is more effective in microorganisms reduction in comparison with soap and regarding its easy application even without water, it is recommended to use it instead if soap for hands as an antiseptic.
