[Applying recommendations of the Braden's scale and preventing pressure ulcers--evidences for nursing care]. / Aplicando recomendações da Escala de Braden e prevenindo úlceras por pressão--evidências do cuidar em enfermagem.

The occurence risk of pressure ulcer (PU) by the patient is questioned as well as the validity of nursing care applying the Braden's scale to verify the evidences of this care in the incidence of the PU. The method of biophysiologic measures in ICU patients was used. It was found 11 patients with PU, in a 26.83% incidence. The majority (57.1%) of ulcer was in stage I. Patients with PU have lower scores than the ones without PU, showing sensitivity to predict the PU risk. It was concluded that: the evidence of nursing care was demonstrated by the density of 47.12% for the patients without PU, the incidence of PU was lower than rates of other UCUs; preventive nursing care reduces the PU.
