What are Alcohol-Based Formulations?
Alcohol-based formulations, commonly known as
hand sanitizers, are antiseptic products that contain a high percentage of alcohol (usually between 60-95%) as the active ingredient. These formulations are used to reduce the number of viable pathogens on the hands and other surfaces.
How Do Alcohol-Based Formulations Work?
Alcohol acts by denaturing proteins and disrupting cell membranes, which effectively kills or inactivates a wide range of
microorganisms, including bacteria, viruses, and fungi. When applied to the hands, they evaporate quickly, leaving behind no residue, which makes them convenient for frequent use.
Before and after touching a patient
Before performing invasive procedures
After contact with bodily fluids or contaminated surfaces
Before and after removing gloves
Efficacy: Highly effective against a broad spectrum of pathogens
Convenience: Easy to use and quick-drying
Accessibility: Can be placed at strategic locations for immediate use
Skin Health: Many formulations contain moisturizing agents to prevent
skin irritation Are There Any Limitations?
Despite their effectiveness, alcohol-based formulations are not a panacea. They are less effective against certain pathogens such as
Clostridium difficile spores and some non-enveloped viruses. Additionally, they may not be suitable for visibly soiled hands, in which case soap and water should be used.
Apply the recommended amount (usually a dime-sized amount)
Rub hands together, covering all surfaces including back of hands, between fingers, and under nails
Continue rubbing until hands are dry, usually around 20 seconds
Flammability: Alcohol is highly flammable; keep away from open flames
Ingestion: Keep out of reach of children to prevent accidental ingestion
Allergic Reactions: Some individuals may experience skin reactions; discontinue use if irritation occurs
Conclusion
Alcohol-based formulations are indispensable in the nursing profession for their efficacy, convenience, and ease of use. By understanding their proper application and limitations, nurses can effectively incorporate these products into their daily infection control practices, thereby enhancing patient safety and care quality.
