Abstract: (48 Views)
Background: Considering the emergence of new diseases, increased prevalence of nosocomial infections, and microbial resistance in recent years, it is necessary to disinfect the hands with a suitable hand sanitizer, as instructed by the Center for Disease Control (CDC). This is because hand hygiene is the most important way to control infections. Surgical hand antisepsis protocols emphasize the importance of both mechanical cleaning and antimicrobial action to effectively eliminate microbial contamination. Recommendations from organizations such as the Association of Perioperative Registered Nurses (AORN), the World Health Organization (WHO), and the Association for Professionals in Infection Control and Epidemiology (APIC) underscore this principle. While routine handwashing removes visible debris and transient microbes, surgical hand antisepsis requires additional steps and the use of antimicrobial agents. This may involve a surgical scrub with an antimicrobial soap or the application of an alcohol-based hand rub (ABHR). The latter approach has demonstrated greater efficacy in reducing microbial contamination compared to soap and water alone. Since a few compressive studies in Iran have dealt with global standards for disinfectants, this study investigated the effects of surgical scrub based on the European standards with TGSept AL Plus, produced by the research team of Tajhiz Gostar Sharif , on normal flora of hands in a group of the operating room medical staff in Hazrat Fatemeh Plastic Surgery and Repair Hospital of Tehran, in 2023.
Methods: This study evaluated the short-term durability and effectiveness of this solution according to the EN12791 standard on microorganisms and microbial contamination reduction. To this end, 30 members of the surgical team were randomly selected. The bacterial sampling was performed three times: after washing the hands with common detergents, after hand scrubbing with the studied disinfectant (about 90 seconds), and three hours after surgery. The samples were immediately transferred to a laboratory for swap culture and pour plate test.

The samples were immediately transferred to a laboratory for swap culture and pour plate test.
| Results: Then bacterial colonies were counted, contamination reduction was measured, and the shelf life of the solution was determined according to the standards. Results showed that a 60-to-90-second scrub with an alcohol-based disinfectant is the best way to reduce hand contamination and, thereby, nosocomial infections. Conclusion: Based on the study findings, alcohol-based solutions can be recommended for surgical scrubs, according to WHO guidelines. |
