Rationale: Reepithelialization of deep burns requires spontaneous or therapeutic removal of necrotic eschar. Debrase is a bromelain derived enzymatic preparation that results in rapid and selective debridement of human and animal burns. We hypothesized that rapid debridement of deep burns with Debrase would speed reepithelialization in a porcine model.
