  1. Describe the differences between sterile, no touch, and clean techniques in relation to cleaning wounds


Sterile Technique

No Touch Technique

Clean Technique

  • A technique where avoiding introducing microorganisms into a wound or area is crucial.
  • E.g., surgical dressing change, catheterization
  • Principles of asepsis are followed.
  • A method of changing a dressing that involves NOT touching the wound with your hand, thus NOT introducing microbes into a wound / area.
  • Principles of asepsis are followed.
  • You can achieve no touch technique by using sterile instruments or sterile gloves.
  • Sterile dressing changes can be done by using sterile instruments to manipulate gauze or dressings.
  • A method of changing a dressing where asepsis is not as crucial. E.g., pressure injury wound (because these wounds are highly colonized).
  • Clean equipment (NOT sterile)
  • Many procedures in a person’s home are done with clean technique because microbes there are part of their normal flora.
