Topical Negative Pressure (TNP): Fields of Applications and Mechanisms of Effect

Abstract

Topical negative pressure (TNP) application is recognized as a valid method to accelerate wound healing process and has been put to active clinical use for the last 15 years. This method incorporates the application of sub atmospheric pressure to a wound in a localized and controlled manner. The device which imposes topical negative pressure, the V.A.C. system (Vacuum Assisted Closure-Kinetic Concept Inc. USA) is being used for our patients by the chronic wound treatment center of our clinic for two years. Shrinkage of wound area, decreased local edema, and increased granulation tissue formation were observed in the lesions treated with TNP. These results have confirmed that, TNP application has become an effective tool for preoperative wound preparation in our clinic. The present study, we reviewed the use and means of benefit of TNP application in our clinic for the last two years were reviewed.
