Negative pressure wound therapy
Negative pressure wound therapy can be used to help close poorly healing wounds and certain types of surgical wounds. Some studies suggest that this treatment can help wounds heal better.
Wounds are typically cleaned and then closed. Usually just an adhesive bandage is needed as a wound dressing for smaller wounds, which then close on their own. The edges of larger wounds can be sewn together, or closed with staples or adhesives, and then treated with a wound dressing.

Different kinds of dressings made of various materials may be used depending on the type of wound. They are used to keep the wound clean, protect it from and help it to heal.
Wounds that don’t close after several weeks despite treatment are considered to be chronic. Inflamed or chronic wounds are cleaned regularly. Dead or inflamed tissue is removed as well. This treatment is called “.”
An extra treatment called negative pressure wound therapy (also referred to as vacuum-assisted closure or VAC therapy) may be recommended for some wounds.
