Hypertonic Glucose Combined with Negative Pressure Wound Therapy to Prepare Wounds with Pseudomonas aeruginosa Infection for Skin Grafting: A Report of 3 Cases.

Soft tissue losses from acute or chronic trauma are a challenge for surgeons. To explore a method to expedite granulation tissue formation in preparation for a split-thickness skin graft (STSG), the medical records of 3 patients - 2 adult men with wounds related to trauma injury and 1 infant with necrotizing fasciitis, all infected with Pseudomonas aeruginosa - were reviewed. All wounds were surgically debrided and managed by applying gauze soaked in 50% glucose followed by continuous negative pressure wound therapy (NPWT) before definitive skin grafting. NPWT pressure was applied at -80 mm Hg for the 2 adult males (ages 39 and 25 years) and -50 mm Hg for the 7-month-old male infant. The dressings were changed every 2 to 3 days. No adverse events occurred, and wounds were successfully closed with a STSG after an average of 7 days. In 1 case, NPWT was able to help affix dressings in a difficult-to-dress area (genital region). The combination of hypertonic glucose and hand-made, gauze-based NPWT was found to be safe, well-tolerated, and effective in preparing the wound bed for grafting. Prospective, randomized, controlled clinical studies are needed to compare the safety, effectiveness, and efficacy of this method to other treatment approaches for P. aeruginosa-infected wounds.
