The authors, who used a home-made system, observed efficient wound cleansing and healing, with marked proliferation of granulation tissue, and no osteomyelitis. Successively, the treatment of patients with compartmental syndrome of the lower limb and of infected, acute or chronic wounds was reported. The duration of treatment ranged from 4 to 31 days, with an average of 13 days. In patients with compartmental syndromes the wounds were subsequently closed by suturing and/or with skin grafts in a smaller number of cases.
In the infected wounds, the negative pressure treatment lasted for 17 days and 3.1 dressings on average were required over the entire period. Most wounds with acute infections were eventually closed by suture, while the remainder healed by secondary intention or were treated with skin grafts. Reinfections and failures represented a small percentage of cases.

Many of the initial experiences in topical treatment with negative pressure were carried out in patients with infected wounds of all kinds, and also in post-actinic chronic ulcers, such as those in soft tissue injuries, including sacral decubitus, post-traumatic lesions, and tissue losses due to fractures of the lower limbs. In most cases a rapid reduction of the initial size of the wound was observed, with a shortening of the healing time and resolution of the pre-existing infection.

In these studies, the negative pressure was achieved by means of conventional equipment, such as wall-mounted vacuum reducers and the classic “suction bottles” connected to various types of dressings isolated from the environment by adhesive sheets used in the operating room. This demonstrates that the system can be implemented in a very simple way, while achieving brilliant results. Naturally the types of medication, the depression levels and the duration of the treatments were not homogeneous and did not allow to standardize the technical aspects of the method.

The first commercial sub-atmospheric pressure dressing system was introduced in the U.S. market in 1995. Since then, negative pressure has been applied to almost every type of wound or injury, giving life to a broad array of scientific literature. In recent years it has also begun to be used in the prevention of infections of high-risk wounds, where it is applied over surgical sutures directly in the operating room at the end of the operation.[/vc_column_text][/vc_column][/vc_row]
