What is negative pressure wound therapy? Negative pressure wound therapy refers to wound dressing systems that continuously or intermittently apply subatmospheric pressure to the surface of a wound to assist healing.
Negative-pressure wound therapy is also called vacuum-assisted wound closure VAC therapy, It has become a popular treatment modality for the management of many acute and chronic wounds.
How does negative pressure wound therapy work? The best pressure for wound healing appears to be approximately mm Hg, using an alternating pressure cycle of 5 minutes of suction followed by 2 minutes off suction.
Animal studies have demonstrated that this technique: Additionally, intermittent low pressure alters the structure of the cells in the wound bed, triggering a cascade of intracellular signals that increase the rate of cell division and formation of granulation tissue. Negative-pressure wound devices and placement There are now several commercially available systems for negative-pressure wound therapy and multiple dressing options engineered for specific wound applications.
Mains-operated systems are available for patients with limited mobility or heavily exuding wounds. Lightweight, battery-powered units have a smaller canister volume suitable for an ambulatory patient with a wound that has minimal to moderate levels of exudate.
Units can be programmed to provide varying degrees of pressure either continuously or intermittently. A foam dressing is cut to the approximate size of the wound with scissors and placed gently over the wound.

A drain tube is placed over the foam. The foam dressing, together with the first few inches of the drainage tube and the surrounding area of healthy skin, is covered with adhesive transparent tape. The distal end of the drain is connected to the negative-pressure unit, which is programmed to produce the required level of pressure.
Once the unit is switched on, the air is sucked out of the foam dressing causing it to collapse inwards, drawing in the edges of the wound with it.
Fluid within the wound is taken up by the foam and transported into a disposable canister within the main negative-pressure unit. Negative-pressure wound therapy dressings should be changed every 48 hours.
If there is infection the dressing should be changed every 24 hours. It may be possible to leave the dressing on for longer periods if the wound is not infected. Depending on the type of wound, negative pressure wound therapy may be needed for 2 — 6 weeks. When is negative-pressure wound therapy appropriate?
The main reasons for using a mains-powered negative-pressure wound therapy unit are: Clinical effectiveness of negative-pressure wound therapy Compared with conventional wound therapy, proposed advantages of negative-pressure wound therapy are: The effectiveness of negative-pressure wound therapy is less certain in patients with:Negative Pressure Wound Therapy Report by Material, Application, and Geography – Global Forecast to is a professional and in-depth research report on the world’s major regional market conditions, focusing on the main regions (North America, Europe and Asia-Pacific) and the main countries (United States, Germany, united Kingdom, Japan, South Korea and China).

The report studies and analyses the sales, status . Negative pressure wound therapy system consists of a vacuum pump, a foam or gauze wound dressing, drainage tubing, and an adhesive film dressing to .
If the circulation of blood underneath the wound is sufficient to replace fluid lost from cells, then the osmotic effect of sugar on the surface simply creates an outflow of lymph. 9 This outflow is beneficial to the healing process, as demonstrated by negative pressure wound therapy.
