Clinical Trial Summary

Intro: Necrotizing and soft tissue infections (NSTI) are life-threatening bacterial infections characterized by subcutaneous tissue, fascia or muscle necrosis. The hospital mortality of NSTI is high, comprised between 20 and 30%. NSTIs represent the 4th cause of septic shock. Early management of NSTIs requires a coordinated and multidisciplinary approach, including broad-spectrum antibiotic administration, management of organ failures and aggressive surgical debridement with excision of all necrotic and infected tissues. NSTIs involve the lower limbs in about 70% of cases and lead in 15% of cases to limb amputation. During the early post-operative phase, daily wound care is required using conventional dressings. As soon as the infectious process is controlled, typically within 7 to 10 days of the initial debridement, the main goal of wound dressing is to allow for a granulation tissue to develop so that to perform a skin grafting. Negative pressure wound therapy (NPWT), which consists in applying a negative pressure on the wound surface, may be used to this effect. A dedicated dressing is connected to a device that generates a negative pressure and collects exudates. NPWT may have a positive effect on wound healing by removing exudate, increasing regional perfusion and patient comfort and reducing infections. Beneficial effects of NPWT have been suggested by case series. However, no randomized controlled trial are currently available to adequately assess its efficiency and the 2014 guidelines of the Infectious Diseases Society of America (IDSA) on NSTI did not provide recommendations regarding NPWT use for managing NSTI wounds. The study's hypothesis is that in patients managed for NSTIs, NPWT: 1) may accelerate skin grafting and complete wound healing; and 2) improve functional outcomes.


Clinical Trial Description

Hypothesis/Objective: To demonstrate in patients who underwent a surgical debridement of the lower limb for NSTI a superiority of a wound dressing strategy using NPWT (intervention) as compared with conventional wound dressing on local healing (complete) and the recovery of walking. Method: Open-label randomized controlled trial with blinded assessment of the primary end point. Randomization in two arms: experimental group (NPWT) versus control group (conventional dressing) until skin grafting (decided by the attending surgeon). ;
