What are key elements of maintaining a sterile field during a procedure?

• A. Keeping the sterile area uncontaminated, performing hand hygiene, using sterile gloves, avoiding contact with non-sterile surfaces, and maintaining sterile technique above waist level.
• B. Maintaining sterile field only after procedure.
• C. Wearing non-sterile gloves at all times.
• D. Leaving non-sterile surfaces in contact with sterile field.

Answer: (A)

Maintaining a sterile field means protecting the area and any items that will touch the patient from contamination throughout the entire procedure. The key is to prevent microorganisms from reaching sterile surfaces by practicing proper hand hygiene, using sterile gloves, and handling only sterile items with careful technique. Keeping the sterile field above waist level helps minimize contamination from the clinician’s clothes and body, and every movement should avoid crossing into non-sterile zones or touching non-sterile surfaces. If a sterile item or surface comes into contact with a non-sterile one, or vice versa, the field is no longer sterile and the risk of infection rises. So, the field must be maintained from setup through completion, with attention to preventing contact, splashes, or transfers of microbes.

Maintaining the sterile field only after the procedure misses contamination that can occur during the work. Wearing non-sterile gloves defeats the purpose of sterility when handling sterile items. Allowing non-sterile surfaces to touch the sterile field obviously contaminates it and compromises the procedure.
