Abstract
Chronic wound or the so-called ‘problem wound’ is defined as any wound that fails to heal within a reasonable period of time by the use of conventional medical or surgical techniques.
This is a common condition that prompts multiple medical visits, prolonged hospitalization, and fastidious nursing care. Non-healing wounds of the lower extremities are the most common although they may occur anywhere on the body.
Thirty patients applied with different types of chronic ulcers and results were collected showing that the application of V.A.C. therapy to a wound has very good effect and enhance wound healing than the enzymatic drbridement agent by provides a moist wound healing environment which is the standard of care of wound healing. Removal of excess interstitial fluid allows cell proliferation and migration, and also helps decrease periwound induration (swelling). V.A.C. therapy was known to improve granulation tissue proliferation and increase the wound vascularity.
The standard dressing in V A C therapy change routine of every 48 hours can result in less disturbance to the wound and improve patients comfort. Finally V.A.C. therapy offers many benefits in chronic wound healing.
V.A.C. (vacuum assisted closure) therapy is an advanced method for wound healing. It is a system that uses controlled negative pressure (vacuum) to promote wound healing.
The V.A.C.Therapy System consists of a computer-controlled therapy unit, canister, sterile plastic tubing, foam dressing, and clear V.A.C. drape dressing. The foam dressing is placed into the wound. One end of the tube is connected to the foam, the other end to a canister that connects to the V.A.C. control unit. The wound area is sealed with the clear V.A.C. drape, similar to a large bandage. The V.A.C. system pulls infectious materials and other fluids from the wound through the tube and collects them inside the canister.
