We previously published the microbial profile of burn wounds managed with NexoBrid® in Pinderfields Regional Burns Centre, Wakefield, UK. Our results showed no significant changes in bacterial colonisation in burn wounds debrided with NexoBrid®. Previous studies described the antimicrobial properties of bromelain enzyme. ⋯ No zones of inhibition were observed around NexoBrid® after 18 h of incubation. Where a combination of controls and test solutions were added, no zones of inhibition were seen around the NexoBrid® wells in any of fifty tested organisms. The slightly lower infection rates observed in patients treated with NexoBrid® are more likely to be due to efficient selective debridement of necrotic skin rather than direct antimicrobial action.

Multifunctional wound dressings have been applied for burn injuries to avoid complications and promote tissue regeneration. In the present study, we fabricated a natural alginate-chitosan hydrogel comprising silymarin and green-synthesized zinc oxide nanoparticles (ZnO NPs). Then, the physicochemical attributes of ZnO NPs and loaded hydrogels were analyzed. ⋯ In vivo studies revealed faster and superior wound healing, achieving nearly complete closure by day 21. Histopathology confirmed improved cell growth, tissue regeneration, collagen deposition, and neovascularization. It is believed that this multifunctional hydrogel-based wound dressing can be applied for effective burn wound treatment.

This study aims to develop an experimental treatment model effective against oxidative stress in the acute period of severe burns and to analyze the mechanisms of healing large wound defects. ⋯ Stem cells may have the potential to form new skin and its appendages, providing better healing for large skin defects. Early excision treatment, by removing local necrotic tissues after extensive and deep burns, can prevent end-organ damage due to systemic oxidative stress and inflammation. We also believe that when these two treatments are used together, they can achieve the best results.
