Use of a Nanoflex powder dressing for wound management following debridement for necrotising fasciitis in the diabetic foot.

This paper discusses the application of Nanoflex powder dressing for management of complex soft tissue wounds. A case report is presented detailing the management of a 43-year-old Native American woman with diabetes mellitus who required serial debridements for necrotising fasciitis. Following debridement, the patient was left with a large dorsal foot wound and was transitioned through multiple advanced wound healing modalities. Negative pressure wound therapy (NPWT) was initially utilised in the early postoperative setting to control drainage and to promote granulation tissue; the patient was subsequently transitioned to a Nanoflex powder dressing on postoperative day 4. She reported a decrease in pain associated with dressing changes when transitioned from NPWT to the use of Nanoflex powder dressing. We hypothesise that this pain reduction is the result of a light cooling effect of the exudate-controlling dressing and subsequent reduction in inflammation as well as the total contact nature of the dressing. Nanoflex powder dressings are a recently developed advanced wound healing modality with promise in the management of complex soft tissue wounds, both as a primary wound dressing as well as a delivery platform for analgesics, antimicrobials and pro-angiogenic compounds.
