Brief 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.

Outcome Measures

Primary Outcomes (1)

  • The time elapsed between randomization and the onset of a combined outcome measure including a complete healing of the diseased limb and the recovery of walking.

    Complete healing of the diseased limb is defined by more than 90% of functional skin covering the wound and Recovery of walking is defined by the ability to walk at least 100 steps, corresponding to approximately 30 meters, without help

    between Day 0 and 3 months

Secondary Outcomes (13)

  • Activities of Daily Living score

    at Day 0, 3 months and 6 months

  • Short Form - 36

    at Day 0, 3 months and 6 months

  • Pain assessment

    between Day 0 and 3 months

  • Quantification of the number of anesthesia procedures (general anesthesia, sedation)

    between Day 0 and 6 months

  • Time elapsed between randomization and skin grafting

    between Day 0 and 6 months

  • +8 more secondary outcomes

Study Arms (2)

Negative pressure wound therapy (NPWT)

EXPERIMENTAL

Negative pressure wound therapy (NPWT): an NPWT device will be applied hermetically from randomization to skin grafting.

Other: Negative pressure wound therapy (NPWT)

Conventional dressing

ACTIVE COMPARATOR

Conventional dressing will be performed from randomization to skin grafting. The dressings will be performed following usual procedures of investigating centers

Other: Conventional dressing

Interventions

The therapeutic intervention being tested is the use of a negative pressure wound therapy (NPWT) device. Several medical devices are currently being used and are based on the same principle. They involve applying negative pressure, generally between -100 and -150 mmHg, to a wound using a dressing (mostly a polyurethane foam dressing with hydrophobic pores), which hermetically covers the wound's surface and is connected to a container for collecting the fluids drained off. These devices are widely available and used to treat post-operative wounds. Duration of treatment: the use of NPWT will be maintained until the recovery of the skin has been achieved by the skin graft. An average duration of 3 weeks' treatment is expected in the intervention group.

Negative pressure wound therapy (NPWT)

Conventional dressings will be performed from randomization to skin grafting and applied every day based on the methods normally used in the participating centres, and also until the recovery of the skin has been achieved by the skin graft. This generally involves local care provided on a daily basis, ensuring gentle mechanical and chemical debridement by covering the wound with alginate type or other dressings, according to the condition of the wound. The methods used to apply these conventional dressings will be recorded.
