The pathology of bedsores located in the sacro-coccygeal region continues to be present in hospital and health care institutions in spite of all the modern scientific advances. Bedsores constitute a serious problem, given their very high cost when they occur and their prevalent nature. Since the relative mortality rate of persons suffering bedsores is significantly higher than that of those who do not suffer them, a careful appraisal and preventive measures are fundamentally desired. Using local therapeutic alternatives based on cicatrisation in a humid medium with modern dressings, those authors proposed an open, prospective, multi-centric study which evaluates the efficiency as well as the behavior of a new hydropolymeric dressing in 3-D specifically designed for ulcerations located in the sacro-coccygeal area. The results indicate that the selected dressing proves to be very useful as a local treatment of sacrum bedsores and in use as a first degree level preventive measure in these areas. This study took under consideration the acceptance of this dressing on behalf of nursing professionals and subjective opinions from patients.
