What measures reduce infection risk in the EP lab beyond sterile technique?

• A. Antibiotic prophylaxis per protocol, proper skin prep, instrument sterilization, and minimizing traffic in the lab.
• B. Only sterile gloves.
• C. Routinely using fans during procedures.
• D. Skipping skin prep to reduce irritation.

Answer: (A)

Infection risk in the EP lab is reduced by combining sterile technique with perioperative measures that limit bacterial introduction and spread. Antibiotic prophylaxis, when used per protocol, helps prevent infections by ensuring adequate antibiotic levels at the time of potential contamination. Thorough skin antisepsis reduces the resident skin flora at the incision or access site, lowering the chance of local infection. Proper instrument sterilization ensures all devices entering the sterile field are free of pathogens. Keeping traffic in the lab to a minimum helps maintain the integrity of the sterile field and reduces the chance of contamination from movement, dust, and disruption of airflow. Relying only on sterile gloves isn’t enough because gloves don’t address skin flora, environmental contamination, or instrument sterility. Fans can spread contaminants, and skipping skin prep would markedly raise infection risk.
