A Study of Vacuum Assisted Negative Pressure Therapy for Wound Healing
Background and objective: Wounds are a major source of morbidity, disability and are associated with increased mortality; therefore, a significant impact on public health and the expenditure of healthcare resources. Vacuum-assisted closure (VAC) uses negative pressure to assist wound healing. Negative pressure drains fluid from the wound, removing the substrate for growth of microorganisms, accelerate granulation tissue formation and promote angiogenesis. The mechanical stimulation of cells by tensile forces may also play a role by increasing cellular proliferation and protein synthesis. Methodology: A total of 50 cases clinically presenting as ulcer between June 2017 and July 2019 were taken for study. Each case was examined clinically in systematic manner as per the proforma. VAC dressing was done and outcome was measured on days 3, 7 and 10. Interpretation and conclusion: In our study VAC therapy enhanced granulation tissue formation leading to better wound healing, and faster recovery. VAC is thus a promising new technology in the field of wound healing with multiple applications in a variety of wounds and can be used in both acute and chronic wounds, salvage procedures or as an adjuvant therapy to improve the results of various surgical procedures.
