Wounds are a consequence of disruption in the structure, integrity, or function of the skin or tissue. Once a wound is formed following mechanical or chemical damage, the process of wound healing is initiated, which involves a series of chemical signaling and cellular mechanisms that lead to regeneration and/or repair. Disruption in the healing process may result in complications; therefore, interventions to accelerate wound healing are essential. In addition to mechanical support provided by sutures and traditional wound dressings, therapeutic agents play a major role in accelerating wound healing. The medicines known to improve the rate and extent of wound healing include antibacterial, anti-inflammatory, and proliferation enhancing agents. Nonetheless, the development of these agents into eluting nanofibers presents the possibility of fabricating wound dressings and sutures that provide mechanical support with the added advantage of local delivery of therapeutic agents to the site of injury. Herein, the process of wound healing, complications of wound healing, and current practices in wound healing acceleration are highlighted. Furthermore, the potential role of drug-eluting nanofibers in wound management is discussed, and lastly, the economic implications of wounds as well as future perspectives in applying fiber electrospinning in the design of wound dressings and sutures are considered and reported.
伤口是皮肤或组织的结构、完整性或功能遭到破坏的结果。一旦因机械性或化学性损伤形成伤口,伤口愈合过程便会启动,这涉及一系列化学信号传导和细胞机制,从而实现再生和/或修复。愈合过程中的破坏可能导致并发症;因此,加速伤口愈合的干预措施至关重要。除了缝线和传统伤口敷料提供的机械支撑外,治疗剂在加速伤口愈合方面发挥着主要作用。已知能提高伤口愈合速度和程度的药物包括抗菌剂、抗炎剂和促增殖剂。尽管如此,将这些药物制成洗脱型纳米纤维为制造伤口敷料和缝线提供了可能性,这些敷料和缝线既能提供机械支撑,又具有将治疗剂局部递送至损伤部位的额外优势。本文重点介绍了伤口愈合过程、伤口愈合的并发症以及当前加速伤口愈合的实践。此外,还讨论了药物洗脱纳米纤维在伤口处理中的潜在作用,最后,考虑并报告了伤口的经济影响以及在伤口敷料和缝线设计中应用静电纺丝纤维的未来前景。
