If contamination occurs in a sterile field, what should you do?

• A. Consider the entire field contaminated and replace items immediately
• B. Continue with the procedure
• C. Sterilize the field again in place
• D. Move to another patient

Answer: (A)

When a sterile field is contaminated, its sterility is broken and cannot be trusted. The safest action is to discard the contaminated field and any items that touched it, then establish a new sterile field with fresh sterile supplies. This protects the patient from introducing pathogens and upholds the principle that a sterile area must remain free of potential contaminants. Continuing the procedure would risk introducing infection, since contaminated surfaces can transfer microbes to the wound or instruments. Attempting to re-sterilize or re-use the compromised field in place isn’t reliable enough to guarantee sterility. Moving to another patient isn’t appropriate until the current situation is resolved, because the breach must be addressed before proceeding with any procedure. In practice, remove the contaminated items using sterile technique, perform proper hand hygiene, re-drape and re-prepare the area, and then resume with a newly established sterile field.
