Effectiveness of Negative Pressure Wound Therapy (NPWT) in abdominal wound dehiscence

Abstract

Abdominal wound dehiscence, a severe postoperative complication, is the partial or total separation of layers of an abdominal surgical wound. This condition is associated with significant morbidity, prolonged hospital stays, and increased healthcare costs. Traditional management involves moist-to-dry dressings, which can be painful and ineffective in promoting rapid wound closure. Negative Pressure Wound Therapy (NPWT), also known as vacuum-assisted closure (VAC), is a modern and effective technique for managing complex wounds. NPWT involves applying controlled sub-atmospheric pressure to the wound bed. This therapy is gaining recognition as a valuable tool for treating abdominal wound dehiscence due to its multiple mechanisms of action. This article reviews the effectiveness of NPWT in managing this challenging condition.  NPWT works through several key mechanisms that are particularly beneficial for complex abdominal wounds: Macro-deformation; Micro-deformation; Removal of exudate. Enhanced Blood  Flow: Negative Pressure Wound Therapy has emerged as a superior treatment modality for abdominal wound dehiscence. Its ability to mechanically close the wound, promote tissue growth, and control infection makes it a highly effective tool for accelerating the healing process. By improving clinical outcomes and reducing the length of hospital stays.
