What is NPWT?
Negative Pressure Wound Therapy (NPWT) is a wound treatment technique that uses a special foam dressing and transparent film to close the wound and uses a negative pressure pump to generate precisely controlled negative pressure to promote wound healing. This technique is often referred to as Vacuum Assisted Closure (VAC) internationally and Vacuum Sealing Drainage (VSD) domestically.VSD and VAC techniques are essentially both NPWT strategies. Its former names include suction wound closure therapy (SWCT), superficial negative pressure therapy (TNP), and subatmospheric pressure therapy (SAP).
NPWT is effective in treating the following types of wounds:
Pressure ulcers (i.e., bedsores)
Diabetic foot or leg ulcers
Venous stasis ulcers
Poorly healing postoperative wounds
Skin graft or donor site
Burns
Penetrating wounds (e.g., abdomen, sternum, spine, perineum)
Fistulas, such as enterocutaneous fistulas, osteomyelitis fistulas, etc.
Undermined sinuses around the wound
Fascial tension-reducing incisions (incisions in the skin and fascia used to treat compartment syndrome).
Effects:
A significant increase in new blood vessels and rapid granulation tissue growth in the wound accelerates wound healing. For example, Philbeck and Whittington found that a comprehensive treatment approach including NPWT can accelerate wound healing by 61% and reduce costs by 38%. Compared to traditional dressing changes, it reduces the frequency of dressing changes. Since dressing changes are very painful, reducing the frequency means patients suffer less pain, which helps patients (less pain, less likelihood of analgesic dependence) and also helps hospitals (reduced treatment frequency, increased efficiency of medical staff). It reduces the likelihood of surgical treatment, and even more so, the likelihood of major surgery. It reduces hospitalization time because (1) wounds heal quickly and infection is less likely, and (2) some patients require continuous treatment but can be treated at home.
