Negative pressure wound therapy is also known as vacuum pressure therapy. It is a new technique; now, it is widely used in various countries. It is mainly used to treat acute and chronic wound and this method is specially used for Diabetic wound by delivering negative pressure to the wound and removing excess fluid from the wound, and it helps to heal the wound faster. This technique has more benefits and many research studies have been conducted. Here, an overview of the history, uses, indications range of pressure techniques mechanism recommended pressure contraindication and complication of negative pressure wound therapy are discussed.
