[Collagen powder dressings in the healing of secondary intention wounds. Report of a case].

The wounds mean not only an important bio-psico-social problem for the patient who suffers them, but also an important economic burden for the sanitary system. One of the many wounds classifications allows us to differentiate between acute wounds (slight traumatism, surgical wounds...) and chronic wounds (pressure ulcers, vascular ulcers...), this differentiation allows us to distinguish between wound healing by primary intention (that occurs in acute wounds where filling of cavity is not needed). And wound repair by secondary intention (the way by which chronic wounds are normally solved), a long process in time that needs the filling of the cavity with a neoformation tissue, the granulation tissue. In the present article we described the use of a new dressing of exogenous collagen (Catrix) in the healing of wounds by secondary intention, as well as the actions of this dressing in the different phases of healing. For all it, we supported by a clinical case treated in our unit that corresponds to the healing by second intention of a post-surgical wound secondary to debride by a suppurative hydrosadenitis, that was admitted to our unit waiting for skin graft.
