Comparison Between Negative Pressure Wound Therapy and Conventional Wound Dressings Before and After Split-Thickness Skin Grafting in Diabetic Foot Wounds

Negative pressure wound therapy is a new noninvasive technique for treating open wounds. It works by removing fluid from the wound bed, reducing edema, and encouraging the growth and perfusion of new granulation tissue. Vacuum-Assisted Closure device (VAC) helps to remove fluid from open wounds through a sealed dressing and tubing which is connected to a collection container. Vacuum-assisted closure (VAC) can provide stable and persistent negative pressure, and there are several modes to choose from. VAC has played an important role in helping to close wounds, controlling infection, promoting angiogenesis, increasing blood flow, and promoting granulation tissue growth in wounds. It is now widely applied in all kinds of acute, chronic, and special wounds with good therapeutic results. However, there is a need to pay attention to contraindications and complications of VAC when it is used, avoiding secondary damage due to improper treatment.
