Negative pressure wound therapy device. Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction pump, tubing, and a dressing to remove excess wound exudate and to promote healing in acute or chronic wounds and second- and third-degree burns.
A dressing or compress [1] is a piece of material such as a pad applied to a wound to promote healing and protect the wound from further harm. A dressing is designed to be in direct contact with the wound, as distinguished from a bandage , which is most often used to hold a dressing in place.
These dressings are generally made with a waxy coating so as to provide a total seal, and as a result do not have the absorbent properties of gauze pads. They are typically used to treat open, or "sucking," chest wounds ( open pneumothorax ) to prevent a tension pneumothorax (a serious complication of a simple pneumothorax).
An alginate dressing is a natural wound dressing derived from carbohydrate sources released by clinical bacterial species, in the same manner as biofilm formation. These types of dressings are best used on wounds that have a large amount of exudate .
Ideally, wound dressings should be changed daily to promote a clean environment and allow for daily evaluation of wound progression. Highly exudative wounds and infected wounds should be monitored closely and may require more frequent dressing changes. [33] Negative pressure wound dressings can be changed less frequently, every 2–3 days. [42]
Hydrogel dressing is a medical dressing based on hydrogels, three-dimensional hydrophilic structure. [1] The insoluble hydrophilic structures absorb polar wound exudates and allow oxygen diffusion at the wound bed to accelerate healing. [2]
