The effect of Hydron burn wound dressing was evaluated using a standard Walker burned rat model (N= 156) and a rabbit ear wound model (N= 34). In both studies Hydron was administered only once in one group and changed twice weekly in another. Animals were predesignated as controls and for pathologic examination. Gross observations, including photographic documentation, and the pathologic analyses revealed no gross purulence or sepsis. No deaths occurred in the rabbit study. Of the 156 animals in the rat study only two died; a culture of the wounds revealed no sepsis. Statistical analyses revealed that in the rat study the once only application was significantly better at 7 days postburn than the twice weekly treatment and control groups. No significant differences among the treatment and control groups used in the rabbit study were revealed. The application of Hydron burn wound dressing did not adversely affect the wound healing.
