The value of negative pressure wound therapy in comparison with the conventional dressing on the postoperative wound healing in diabetic foot patients

Authors

Abstract

Background
Diabetic foot ulcers (DFUs) constitute one of the most important complications of diabetes mellitus. If not treated promptly, progression of infection and sepsis may necessitate a limb amputation.
Aim
The aim of the study was to evaluate the clinical efficacy of negative-pressure wound therapy using vacuum-assisted closure (VAC) compared with the conventional dressing on the postoperative wound healing in diabetic foot patients.
Patients and methods
This was a randomized controlled trial that included two groups of postoperative diabetic foot patients, in which we had a comparison between VAC and conventional wound dressing in order to investigate which procedures had the least time of follow-up weeks for full granulation of wound.
Results
Negative-pressure wound therapy significantly reduces the time to complete wound healing by enhancing the formation granulation tissue.
Conclusion
The time to complete wound healing was significantly better in the VAC therapy group as compared to conventional dressing.
