A composition and method for treating a wound with an inherently antimicrobial dressing. The dressing is a hydrogel containing from about 15 to 95 percent, and preferably from about 61 to 90 percent, by weight of a cationic quaternary amine acrylate polymer prepared by the polymerization of acryloyloxyethyl(or propyl)-trialkyl(or aryl)-substituted ammonium salts or acrylamidoethyl(or propyl)-trialkyl(or aryl)-substituted ammonium salts. The antimicrobial hydrogels are non-irritating to the wound, absorb wound exudate, and, due to the inherently antimicrobial properties, enhance the sterile environment around the wound. The hydrogels have sufficient adhesive properties that loose contact with the wound is assured but can also be removed without leaving any gel residue on the wound. The wound dressings are preferably formed on a substrate, such as a web or patch, for ease in application to and removal from the wound. If desired, additional antimicrobial or other pharmaceutically active agents can also be incorporated into the hydrogel structure.

La présente invention concerne une composition et un procédé de traitement de plaies à l'aide d'un pansement à propriétés antimicrobiennes endogènes. Le pansement est un hydrogel contenant environ entre 15 à 90 pour cent, et de préférence environ entre 61 à 90 pour cent en poids d'un polymère d'amine quaternaire cationique acrylique, préparé par la polymérisation de sels d'ammonium substitués d'acryloyloxyéthyle (ou propyle)-trialkyle (ou aryle) ou de sels d'ammonium substitués d'acrylamidoéthyle (ou propyle)-trialkyle (ou aryle). Les hydrogels antimicrobiens sont non irritants pour les plaies, absorbent les sécrétions des plaies, et, en raison des propriétés antimicrobiennes endogènes, augmentent l'environnement stérile autour des plaies. Ces hydrogels possèdent des propriétés d'adhésion suffisantes qui permettent d'assurer un contact lâche avec la plaie et un enlèvement sans laisser de gel résiduel sur la plaie. Les pansements sont de préférence formés sur un substrat, tels qu'une toile ou une bandelette, de manière à en faciliter l'application et l'enlèvement de la plaie. Il est aussi possible d'incorporer, dans la structure de l'hydrogel, un antimicrobien supplémentaire ou d'autres agents actifs sur le plan pharmaceutique.
