Context: Antiseptic hand preparations are routine prior to surgical procedures to reduce microbial load on the operating gloved hands. Two methods of surgical hand preparations available are the antibacterial detergent hand wash and an alcohol-based hand rub. Aim: The aim of the study was to compare quantitatively, the efficacy of the two methods in hand bacterial reductions during elective orthopedic surgeries. Setting and Design: This comparative study was conducted at the orthopedic surgery department of a tertiary health facility. Subjects and Methods: One-hundred and sixty dominant hands of operating surgeons and nurses involved in forty elective orthopedic surgeries were studied. The subjects were randomly assigned to either the antibacterial detergent hand-washing (HW) or the alcohol-based hand-rubbing (HR) groups. Swab samples were obtained from the hands before and after hand preparations and at the end of surgeries following removal of the operating gloves. These samples were then subjected to culture. The bacterial counts on these were then obtained through an automated colony counter, and the results were expressed in logarithmic values (log10). Statistical Analysis Used: The analysis was done using IBM SPSS software version 20. The mean results obtained were subjected to an independent t-test analysis with the statistical significance level set at P < 0.05. Results: Both methods of hand antisepsis showed comparable efficacies in attaining surgical hand hygiene at 1-min postapplication (P = 0.73). HR group, however, showed greater sustained effects during the period of surgeries, though not statistically significant (P = 0.18). Conclusion: Scrubbing using the HR method is a viable alternative to the HW method during elective orthopedic surgery.
