Role of Negative Pressure Wound Therapy in Healing of Diabetic Foot Ulcers

Abstract

Introduction: Foot disorders such as ulceration, infection
and gangrene are the most common, complex and costly
sequelae of diabetes mellitus.[1-3] Even for the most superficial
wounds, treatment is often difficult with poor healing responses and high rates of complications. The purpose of this study is to compare the rate of ulcer healing with the negative pressure dressing technique to conventional moist dressings in the treatment of diabetic foot ulcers.
Materials and Methods: The study was conducted on 30 patients, which were divided into two groups. One group received negative pressure dressing while other group received
conventional saline moistened gauze dressing. Results were
compared for rate of wound healing.
Results: There was a statistically significant difference in the rate of appearance of granulation tissue between the two groups; with granulation tissue appearing earlier in the study group. The study group promised a better outcome (80% complete responders) as compared to the control group (60% complete responders).
Conclusions: Negative pressure wound therapy has a definitive role in healing of diabetic foot ulcers.
