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
