However, a new species of dressing has evolved in the rainforest and is finding its place amid the more established ones. Evolutionary Need for the Hydropolymer Adhesive Dressing Evolution is change in response to an unmet need. With all of the wound dressings available, it may appear that all possible wound management needs could be met and that there would be no driving need for a new dressing to evolve. However, if we examine the performance characteristics of some of the previously existing dressing categories in relation to the management needs of a moderately draining wound, the opportunity for a new species of dressing will become more apparent. Transparent film dressings are adherent, requiring no secondary dressing.
Some hydrocolloids have a claim for moderately exuding wounds.
However, they have a low rate of absorption, often melt down as they absorb drainage, and may cause skin stripping if used inappropriately because of their high level of adhesion. 5 Alginates have a high rate of exudate absorption but require a secondary dressing for attachment to the patient. Alginates can leave fibers in the wound bed if drainage is insufficient to fully gel the material or if the secondary dressing allows the gelled material to dry out. Foam products are capable of absorbing wound exudate and may or may not require a secondary dressing for attachment. Many exhibit a resiliency that can impact their conformability in anatomically challenging areas.
