Wound

Summary
A wound is a rapid onset of injury that involves lacerated or punctured skin (an open wound), or a contusion (a closed wound) from blunt force trauma or compression. In pathology, a wound is an acute injury that damages the epidermis of the skin. To heal a wound, the body undertakes a series of actions collectively known as the wound healing process. Classification According to the level of contamination, a wound can be classified as:
  • Clean wound – made under sterile conditions where there are no organisms present, and the skin is likely to heal without complications.
  • Contaminated wound – usually resulting from accidental injury; there are pathogenic organisms and foreign bodies in the wound.
  • Infected wound – the wound has pathogenic organisms present and multiplying, exhibiting clinical signs of infection (yellow appearance, soreness, redness, oozing pus).
  • Colonized wound – a chronic situation, containing pathogenic organisms, difficult to heal (e.g. bedsore).
