A Study of Role of Vacuum (VAC) Assisted Dressing in Surgical Wound

Abstract

Background: Negative pressure wound therapy (NPWT), formerly known as vacuum-assisted wound closure, is an effective alternative to traditional wound closure methods. It accelerates tissue debridement and promotes healthy granulation, especially for chronic wounds and ulcers. The process involves placing a foam dressing, perforated wound drain, and adhesive film over the wound, and then applying intermittent negative pressure (~-125 mmHg). This reduces swelling, draws out excess fluid, improves blood flow, lowers bacterial counts, and stimulates cell growth, creating an optimal environment for wound healing Aims: A study of vacuum assisted dressing in surgical wound Objectives: To assess the efficacy; to evaluate the impact on granulation tissue formation; to observe the isolated organisms; to observe the duration of hospital stay Methodology: Study was conducted on total 30 patients with surgical wound at SMS hospital. VAC dressing applied to the patients and study was conducted to observe duration of hospital stay, enhancement of granulation tissue, bacterial count and size of wound. Result: In study of 30 patients with VAC dressing 18 undergo split thickness skin graft, 6 undergo healing by secondary intentions, 4 patients required re operation (debridement / amputation) and 2 patient required flap closure. Conclusion: VAC dressing stabilizes the wound increase perfusion decreases bacterial load and reduce need of major plastic surgical intervention. It reduces the hospital stay and reduces overall treatment cost.
