The principles of negative pressure

Negative pressure wound therapy (NPWT) delivers vacuum-assisted pressure below the wound surface to help promote healing. NPWT consists of a wound dressing (foam or gauze), a drainage tube, and a transparent film that is connected to a suction device.

NPWT is particularly effective at:

  • Promoting granulation tissue formation
  • Restoring moisture balance
  • Improving perfusion

NPWT is indicated for patients with:

  • Pressure ulcers
  • Diabetic ulcers
  • Chronic, acute and traumatic wounds
  • Sub-acute and dehisced wounds
  • Skin grafts and flaps

NPWT is contraindicated for:

  • Untreated osteomyelitis
  • Presence of necrotic tissue with eschar
  • Exposed organs, arteries, veins or nerves
  • Malignancy in the wound bed
  • Non-enteric and unexplored fistulas
  • Anastomotic sites
