Abstract:Chronic wounds are characterized by complicated pathogenesis, easy recurrence, long treatment time, great difficulty, high cost and high disability rate which have serious negative impacts on the life quality of patients. The treatment of chronic wounds is one of the difficult problems of wound treatment today. Wound dressings play a key role in wound treatment, especially the functional dressings with biomacromolecules as matrix components. Because of good biocompatibility, biodegradability, low toxicity and other biological characteristics, biomacromolecules can be made into various biological dressings for chronic wound repair, and can be modified or compounded with enhanced performance as a dressing. This article reviewed the research progresses of biomacromolecule-related properties and the applications of biomacromolecule dressings in chronic wound repair. It indicates that biomacromolecule dressings have great application prospects in chronic wound repair, providing ideas and help for clinical research of biomacromolecule dressings.
