Abstract
This invention provides compositions and methods of treating subjects with wounds. Compositions include dressings comprising a sheet and an adhesive, wherein the adhesive is adhered to the sheet, and wherein the sheet has channels. In some embodiments, the channels comprise two different classes of channels (e.g. liquid channels and air channels). These dressing can be applied to various kinds of skin injuries and remain affixed, protecting the injury from contaminants and at the same time, allowing exchange of exudates on the proximal (injury) side to the distal side and exchange of topical agents applied from the distal side of the dressing to the wound while also allowing exchange of gasses from the injury to the air and air to the wound.
