Abstract

The nature of the wound typically dictates the available wound-healing therapies. On the other hand, inadequate care results in persistent wounds, fibrosis, tissue loss of function, and ultimately dismemberment. Suturing, unloading, irrigation, debridement, negative pressure therapies, growth factor supplementation, and grafting are examples of current medicines that all have limitations in terms of meeting the needs of full treatment. Natural or synthetic materials/polymers have been utilized to prepare smart thermosensitive hydrogels to facilitate quick and targeted action on wounds. These are intelligent hydrogel system that shows sol-gel transitions at physiological body temperature. Hydrogel provides a moist environment, scaffold-like structure, and localized delivery of drug/growth factor that speed up wound healing even if it eliminates side effects associated with systemic administration. In this article, we summarized the detailed mechanisms of wound healing, conventional strategies, and ongoing thorough research work in the field of thermosensitive hydrogels utilized for wound healing. Moreover, the clinical needs of this formulation, as evident from the commercially available systems are also described in the prior art.
