What are the requirements for proper donning and doffing of disposable isolation gown and the importance of maintaining sterile conditions?
Preparation: Before donning an isolation gown, it is crucial to ensure hands are clean by washing them thoroughly with soap and water or using an alcohol-based hand sanitizer. Hands should be dried properly before proceeding to prevent contamination of the gown.
Selecting the appropriate size: It is important to wear the correct size of isolation gown to ensure adequate coverage and protection. Gowns that are too tight may limit movement, while those that are too loose may increase the risk of exposure.
Gowning technique: Open the gown fully and allow it to fall freely. Grasp the gown at the neck or shoulder area and then put your arms through the sleeves. Ensure that the gown covers the front and back of your body, extending to at least the mid-calf level or as specified by the manufacturer. Fasten any ties, snaps, or Velcro closures securely.
Fastening the gown: Make sure that all fasteners properly secured to provide a snug fit. This prevents accidental exposure and minimizes risk of contamination.
Maintaining sterile conditions: It is crucial to maintain a sterile environment when donning and doffing isolation gowns. This includes performing the procedure in a designated area with controlled contamination levels, such as a cleanroom or a dedicated isolation room. It is also important to follow aseptic techniques, such as using proper hand hygiene, avoiding unnecessary contact with surfaces, and minimizing movement within the area.
Adhering to proper order: Gowns should be donned before wearing gloves or other personal protective equipment (PPE). This prevents the risk of contamination when reaching over the gown during the glove-donning process.
Avoiding self-contamination: During donning, it is crucial to minimize the risk of self-contamination by not touching the face, hair, or other exposed areas. This can be achieved by being mindful of movements and using mirrors or assistance to ensure proper gown fit.
Proper doffing procedure: After use, the isolation gown should be carefully removed to prevent contamination. This involves unfastening any closures while avoiding vigorous movements that may dislodge potentially contaminated particles. The gown should be folded or rolled into itself without touching the outer surface, ensuring containment of any potential pathogens.
