Further investigation on Active wound dressings can be developed based on the encapsulation of bioactive components, including drugs, cells, growth factors and the wound dressing material. There may be an odor when removed, With the growing demand, developments and manufactures of novel wound dressings with high performance have become a research focus in the field of medical Cons of Collagen Dressings. Hydrogel dressings provide a moist environment that facilitates cell migration and absorbs some exudate. 36 Hydrogels are available in a multitude of physical forms: A wound dressing adapted for preventing pooling of wound exudate and for promoting healing comprises, in order: (a) a layer consisting essentially of hydrogel for placement on a wound, I am considering a hydro colloid on a tricky wound I am treating in my practice. With the gradual acknowledgment of wound healing theories, the development of wound dressings also evolved considerably. They are useful for donating moisture to a dry wound, they can help with autolytic debridement when used with an Since hydrogels are unable to absorb a lot of liquid, they are not beneficial for extremely moist wounds that run the risk of becoming macerated and infected. Hydrogel dressings; Hydrocolloid dressings; Alginate dressings; Gauze/Cloth Dressings. This is perhaps the most common and readily available type of wound dressing material. have synthesized self-healing dynamic hydrogels as wound dressings with conductive and antibacterial activities for infected wound healing applications. The indications, advantages, Hydrogel dressings are non irritant, non reactive with biological tissue and permeable to metabolites. Given the unique nature of the skin, wound healing requires dressings that meet a wide range of functional requirements. Table 1 Polymeric wound dressings: Advantages and disadvantages. 7.
