Areas of usage:
- Arterial Insufficiency Ulcers
When is NPWT contraindicated?
- Underlying osteomyelitis.
- Necrotic tissue (slough or eschar)
- Exposed internal organs (for example Intestines, blood vessels / vascular grafts/ suture junctions etc)
How does NPWT promote wound healing?
- Negative Pressure Wound Therapy is the latest in wound care, which uses subatmospheric pressure.
- It increases blood flow to the wound (better blood supply means, quicker healing) and good blood supply brings antibiotics to the wound along with body’s own healing mechanisms.
- Sucks out wound discharges and bacteria which otherwise impair growth of granulation tissue in the wound. (Good granulation, means better healing)
- By removing excess (unwanted) fluid, reduces tissue edema and improves tissue oxygenation.
- Perfusion of blood improves towards the wound
- Stimulates and promotes healthy granulation tissue formation
- Encourages wound contraction and expands the surrounding skin
- Maintains a moist wound environment
