Role of negative pressure wound therapy in healing of diabetic foot ulcers.

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.
