Burns and chronic wounds present significant challenges in wound management due to risks of infection, excessive inflammation, and prolonged healing. Silver-based treatments have long been central to burn care, but limitations have prompted the exploration of nanocrystalline silver as an alternative, with its nanoscale properties offering distinct benefits. This paper reviews the structure, properties, mechanisms of action, and clinical applications of nanocrystalline silver in burn and general wound management, with particular emphasis on how wound healing processes inform the application of these dressings. Nanocrystalline silver's high surface area-to-volume ratio and crystal structure enhance its antimicrobial and anti-inflammatory efficacy. Nanocrystalline silver's mechanisms of action are disrupting cellular functions, inducing DNA damage, and inhibiting biofilms. Clinical studies demonstrate accelerated healing and reduced inflammation compared to traditional treatments. Whilst nanocrystalline silver dressings are costly, their effectiveness in lowering drug-resistant infections and minimising complications supports a financial case for their use, potentially reducing overall wound care expenses. Considerations of cytotoxicity, allergic reactions, and accessibility underscore the importance of individualised treatment selection based on wound and patient factors. In conclusion, nanocrystalline silver holds substantial promise in burn wound management, and further research is warranted to optimise its therapeutic potential and economic benefits in clinical practice.
由于存在感染、过度炎症反应和愈合时间延长的风险,烧伤和慢性伤口的伤口处理面临重大挑战。长期以来,银基治疗一直是烧伤护理的核心,但由于其局限性,促使人们探索将纳米晶银作为一种替代方案,其纳米级特性具有独特的优势。本文综述了纳米晶银在烧伤和一般伤口处理中的结构、特性、作用机制及临床应用,特别强调伤口愈合过程如何为这些敷料的应用提供依据。纳米晶银的高比表面积和晶体结构增强了其抗菌和抗炎功效。纳米晶银的作用机制包括破坏细胞功能、诱导DNA损伤和抑制生物膜形成。临床研究表明,与传统治疗方法相比,纳米晶银可加速伤口愈合并减轻炎症反应。虽然纳米晶银敷料成本高昂,但其在降低耐药性感染和减少并发症方面的有效性支持了其使用的经济合理性,有可能降低总体伤口护理费用。细胞毒性、过敏反应和可及性等方面的考虑凸显了根据伤口和患者因素进行个体化治疗选择的重要性。总之,纳米晶银在烧伤伤口处理中具有巨大潜力,有必要进一步开展研究以优化其在临床实践中的治疗潜力和经济效益。
