Pressure sores

Abstract

Among the broad spectrum of complex wounds the pressure ulcer can be defined as a localized lesion, affecting the skin and/or underlying tissue usually over a bony prominence, resulting from pressure or pressure combined with shear and/or friction. Risk factors for pressure ulcers are those that predispose an individual to prolonged periods of ischemia induced by pressure, and reduce the ability of the tissue recovery of a ischemic injury, which can have associated factors, intrinsic or extrinsic. The classification of pressure ulcers and prevention scales are numerous. However, for pressure ulcers with complications or advanced depths the determinant treatment is surgery. In recent years, the introduction of negative pressure dressing for treatment of complex wounds, as are many pressure ulcers, was very important as an adjuvant therapy surgery
