Key features
ยWound dressings have evolved from simple wound coverings to more active wound management tools that directly interact with the wound environment
ยNo perfect dressing exists for all wounds but when used
ยญappropriately, dressings can improve healing time and cosmesis as well as reduce pain and infections
ยSemipermeable or occlusive dressings provide a moist environment, retain wound fluid that contains growth factors conducive to healing, and promote a low tissue oxygen tension that stimulates angiogenesis and deposition of collagen
ยThe major types of moisture-retentive dressings include films, foams, hydrogels, alginates, gelling fibers, hydrocolloids, and superabsorbents
