Pressure ulcers.
Pressure ulcers are localized areas of tissue necrosis that result from unrelieved pressure. They are graded or staged according to the degree of tissue damage observed. The main etiologic factors include pressure, shearing forces, friction, and moisture. The clinical course may be complicated by several conditions including infection, sepsis, osteomyelitis, fistulas, and carcinoma. Preventive measures in persons at risk can significantly reduce the incidence of pressure ulcers. Successful management should address the four etiologic factors as well as the general condition of the patient.
