The two primary methods for surgical hand preparation are a water-based scrub using antimicrobial soap and a waterless scrub using an alcohol-based hand rub. These techniques aim to eliminate transient microorganisms and reduce resident flora on the hands and forearms of surgical personnel.
Here's a breakdown of each method:
-
Water-Based Scrub (Antimicrobial Soap): This traditional method involves a thorough washing of the hands and forearms with a suitable antimicrobial soap and water.
- Typically requires 2-10 minutes, depending on the specific soap and protocol.
- A scrub brush or sponge may be used to aid in mechanical removal of debris and microorganisms.
- Requires careful rinsing to remove all soap residue.
-
Waterless Scrub (Alcohol-Based Hand Rub): This method uses an alcohol-based hand rub containing persistent antimicrobial activity.
- Usually faster than the water-based scrub, often requiring 2-5 minutes.
- The product is applied to all surfaces of the hands and forearms and allowed to air dry.
- Considered more effective by some studies, as alcohol is a potent antimicrobial agent.
- Less damaging to the skin compared to traditional scrubbing.
In summary, both the water-based scrub and the waterless alcohol-based rub are accepted methods for surgical hand preparation. The choice between the two often depends on factors like facility protocol, surgeon preference, and the specific characteristics of the available products.
