Wear surgical caps in operating rooms, delivery rooms, and burn units. Refrain from sneezing or coughing over a sterile field. This can make it un-sterile because droplets containing microorganisms from the respiratory tract can travel 1 m (3 ft). Some nurses recommend that masks covering the mouth and the nose should be worn by anyone working over a sterile field or an open wound. Nurses with mild upper respiratory tract infections refrain from carrying out sterile procedures or wear masks. When working over a sterile field, keep talking to a minimum. Avert the head from the field if talking is necessary. To prevent microorganisms from falling over a sterile field refrain from reaching over a sterile field unless sterile gloves are worn and refrain from moving unsterile objects over a sterile field. Unless gloves are worn, always hold wet forceps with the tips below the handles. When the tips are held higher than the handles, fluid can flow onto the handle and become contaminated by the hands. When the forceps are again pointed downward, the fluid flows back down and contaminates the tips. During a surgical hand wash, hold the hands higher than the elbows to pre-vent contaminants from the forearms from reaching the hands. Sterile moisture-proof barriers are used beneath sterile objects. Liquids (sterile saline or antiseptics) are frequently poured into containers on a sterile field. If they are spilled onto the sterile field, the barrier keeps the liquid from seeping beneath it. Keep the sterile covers on sterile equipment dry. Damp surfaces can attract microorganisms in the air. Replace sterile drapes that do not have a sterile barrier underneath when they become moist. A 2.5 cm (1 in) margin at each edge of an opened drape is considered un-sterile because the edges are in contact with unsterile surfaces. Place all sterile objects more than 2.5 cm (1 in) inside the edges of a sterile field. Any article that falls outside the edges of a sterile field is considered unsterile. Use sterile gloves or sterile forceps to handle sterile items. Prior to a surgical aseptic procedure, wash the hands to reduce the number of microorganisms on them.
Conscientiousness, alert-ness, and honesty are essential qualities in maintaining surgical asepsis. When a sterile object becomes unsterile, it does not necessarily change in appearance. The person who sees a sterile object become contaminated must correct or report the situation. Do not set up a sterile field ahead of time for future use. c.
