Decubitus is a focal injury to the skin and subcutaneous tissue caused by pressure or friction or both. It is localized on bony protrusions. They most often affect people with reduced mobility after long-term neurological conditions. They are one of the most common causes of unplanned hospitalizations in patients with spinal cord injury. They can present clinically as permanently hyperemic, blistered, damaged or necrotic skin that can extend to underlying structures, including muscles and bones, and sometimes even joints. Decubitus poses a huge economic and health burden to caregivers and the health care system as a whole. Prevention of pressure ulcers is therefore a high priority. At a time when resources are limited, it is necessary to calculate the costs of prevention and treatment of pressure ulcers in order to assess the impact it has on the healthcare system and society. The diploma thesis presents pressure ulcers, risk factors, and methods of treatment. The emphasis is on prevention. The nurse primarily cares for a patient with pressure ulcers, and in this regard it is important to know all the risk factors and methods of its care, with the implementation of special measures to prevent damage to the integrity of the skin of an immobile neurological patient.
