Abstract
BACKGROUND: We describe 3 cases where negative-pressure wound therapy with instillation and dwell time (NPWTi-d) was used as an adjunctive therapy for 3 chronic wounds.
CASES: Three patients (2 males and 1 female), ranging in age from 28 to 53 years, presented with complex, infected wounds: (1) a diabetic foot ulcer with underlying infection, (2) a dehisced abdominal wound with enterocutaneous fistula, and (3) a large wound of the upper torso and axillary region resulting from soft tissue necrosis. Negative-pressure wound therapy with instillation and dwell time was initiated by instilling normal saline or an antiseptic solution; the solution was left in place for 3 to 10 minutes. Continuous negative pressure was then applied at -125 or -150 mm Hg; cycles were repeated every 1 or 3 hours. Treatment was applied for 5 to 44 days, and dressings were changed every 2 to 3 days. Granulation tissue developed in all 3 wounds; all closed after subsequent skin grafting.
CONCLUSIONS: Outcomes of these cases suggest that NPWTi-d may be used as an adjunctive treatment modality for a variety of chronic wounds.
