Mean Healing Time of Wound After Vacuum Assisted Closure (VAC) Versus Conventional Dressing in Diabetic Foot Ulcer Patients

"In participants undergoing vacuum assisted closure a drainage tube was placed in the wound followed by dressing with sterile foam sheet and application of occlusive transparent film over the whole assembly. The drainage tube was connected to a suction machine. Intermittent negative pressure of -125mmHg was applied every 15 minutes; the suction was stopped for 10 minutes. The dressing was changed every 48 hours.~In participants with conventional dressings, after wound wash, pyodine soaked gauze pieces were used for initial 48 hours followed by dressings of normal saline soaked gauze pieces, twice daily."
