Wound exudates, the effusion of tissue fluid after injury, can act as a bridge for biochemical substance transfer and provide an environment for wound healing. However, excessive wound exudate prolongs the inflammatory phase and hinders healing, particularly in chronic wounds. Although dressings have long been used to absorb exudates and protect wounds, traditional dressings have non-negligible limitations in exudate management because of their single structure and function. Materials with asymmetric wettability and specific pore structures have unique advantages for controlling unidirectional liquid transport, providing a new approach for exudate management. In recent years, exudate management dressings have advanced significantly, but have seldom been described and discussed in detail. Therefore, this review systematically presents the mechanism, necessity, and configurations of exudate management dressings. Variously, textile-, nano/microfiber-, membrane-, foam/sponge-based, and composite exudate management dressings are reviewed. The methods for evaluating exudate management are briefly described and the current challenges and prospects are presented to provide references for the future development of dressings.

用于伤口渗出物管理的多功能敷料


伤口渗出液是受伤后流出的组织液，可以作为生化物质转移的桥梁，为伤口愈合提供环境。然而，过多的伤口渗出物会延长炎症期并阻碍愈合，尤其是慢性伤口。尽管敷料长期以来被用来吸收渗出液和保护伤口，但传统敷料由于其结构和功能单一，在渗出液处理方面存在不可忽视的局限性。具有不对称润湿性和特定孔隙结构的材料在控制单向液体输送方面具有独特的优势，为渗出液管理提供了新方法。近年来，渗液处理敷料取得了显着进步，但很少被详细描述和讨论。因此，本文系统地介绍了渗液处理敷料的机制、必要性和配置。对纺织品、纳米/微纤维、膜、泡沫/海绵和复合渗出液管理敷料进行了不同程度的审查。简要介绍了评估渗出液管理的方法，并提出了当前面临的挑战和前景，为未来敷料的发展提供参考。
