Summary for Patent: 4,563,184

Title: Synthetic resin wound dressing and method of treatment using same
Abstract:A synthetic resin wound dressing (e.g., a burn wound dressing) is disclosed consisting essentially of a polymer, such as poly(2-hydroxyethylmethacrylate), referred to as PHEMA, an organic solvent, such as polyethylene glycol (PEG), and a hydrogen binding plasticizer, such as dimethylsulfoxide (DMSO). The plasticizer regulates the set-up time of the synthetic resin so that the more plasticizer present, the shorter the set-up time. The dressing may be applied to the wound site in the form of a paste for the in situ curing or setting thereof, or the dressing may be preformed and then applied to the wound site. A variety of drug agents (e.g., silver sulfadiazine) may be incorporated in the synthetic resin so as to result in the time released administration of the drug agent to the area of the skin (e.g., a burn wound site or the like) covered by the wound dressing. A method of treatment using this dressing is also disclosed.
