Vacuum assisted wound closure therapy.

Abstract

Vacuum assisted closure (VAC) therapy is designed to promote the formation of granulation tissue for faster healing in the wound beds of patients with acute and chronic wounds. Four controlled trials and one interim analysis provide poor quality data and weak evidence that VAC therapy may be superior to conventional methods used in healing wounds. Complications with VAC therapy are uncommon. Studies are needed to evaluate the effectiveness of VAC therapy when the types of dressings are the same for patients in the groups being compared and VAC therapy is the only differing intervention.
