title: [Wound dressings in chronic wounds].
abstract: Hydroactive wound dressings retain exsudate in the wound region or incorporate wound exsudate by gel formation. They create the local environment for moist wound healing which is experimentally and clinically characterized by accelerated reepithelialization, inflammatory reaction and angiogenesis as well as reduced wound pain and wound infection rates. Clinically relevant product groups of hydroactive wound dressings (hydrocolloids and hydropolymers, semipermeable films, calcium alginates) are distinct as to chemical structure, physical properties and functional characteristics in local wound treatment. Between the product groups, there are considerable differences with respect to inflammatory reactions at the wound bottom, absorption of exsudate, occlusion properties, wound edge adherence, adaptability to the wound shape and material integrity of wound dressings. Experimental and clinical results of moist wound treatment by hydroactive wound dressings such as hydrocolloids and hydropolymers, semipermeable films or calcium alginates reveal a wide range of local response on the different types of dressings. They offer the opportunity of therapeutic differentiation. To elucidate the differential indication for different product groups of hydroactive wound dressings in local treatment of chronic wounds, additional experimental and clinical research is required.
