Clinical overview

The principles of traditional negative pressure wound therapy (tNPWT)

Negative pressure wound therapy involves the application of controlled levels of subatmospheric (negative) pressure to a wound to promote healing1. Traditional NPWT consists of a wound dressing (foam or gauze), a drainage tube, and a transparent film, sealed over the wound and connected to a suction device.

Mode of action

tNPWT is particularly effective at:

  • Promoting granulation tissue formation1
  • Restoring moisture balance
  • Improving perfusion

tNPWT is indicated for patients with:

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

tNPWT 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 site
