Pressure Ulcer Necrosis

Necrosis occurs when there is not enough blood flowing to the tissue, ultimately resulting in death of body tissue. It is often necessary to surgically remove the tissue that looks black, as it impairs the pressure ulcer from healing and hinders the assessment of the pressure ulcer size and depth. The risk factors for the development of pressure ulcer necrosis can be attributed to the following:

  • skin abnormalities
  • dehydration and poor nutrition
  • prolonged pressure
  • immobility
  • sensory loss
  • friction
