According to the 2004 ASRA practice advisory, what is the most important action to maintain aseptic technique and prevent cross-contamination during regional anesthesia techniques?

• A. Wearing surgical gown
• B. Hand washing
• C. Using soap and water instead of alcohol-based antiseptics
• D. Keeping fingernails short

Answer: (B)

Hand hygiene is the most important step to maintain aseptic technique in regional anesthesia. Cleaning the hands removes the majority of bacteria and other microbes that can be carried from one patient to another or to sterile equipment, and it directly reduces the risk of introducing pathogens during needle insertion, catheter placement, and skin prep. This foundational action protects the entire process, as gloves and sterile barriers do not replace the need for clean hands. After proper hand washing, using an alcohol-based hand rub can be appropriate during routine inter-case periods, but soap and water must be used when hands are visibly dirty or when contamination is suspected. Other measures like keeping nails short or wearing a gown contribute to barrier protection, but they do not address the primary route of contamination as effectively as thorough hand washing.
