Sterile is generally defined as meaning free from microorganisms.3 Sterile technique involves strategies used in patient care to reduce exposure to microorganisms and maintain objects and areas as free from microorganisms as possible.
Sterile technique involves meticulous hand washing, use of a sterile fi eld, use of sterile gloves for application of a sterile dressing, and use of sterile instruments. “Sterile to sterile” rules involve the use of only sterile instruments and materials in dressing change procedures; and avoiding contact between sterile instruments or materials and any non-sterile surface or products.
Sterile technique is considered most appropriate in acute care hospital settings, for patients at high risk for infection, and for certain procedures such as sharp instrumental wound debridement.
