The concept of death was linked to the absence of heartbeats or spontaneous breathing movements. Diagnosis of brain death is complex, requiring a series of initial factors as prerequisites, such as: knowledge of the cause of the coma, absence of hypothermia and absence of action of central nervous system depressant drugs. Objective: to verify the clinical incidence and epidemiology of brain deaths in Brazil. Methodology: these are exploratory, retrospective observational or experimental studies of literature recovery and critical analysis that were carried out through a search of electronic documents published between 2010 and 2020, using scientific articles, dissertations and theses. Thirty-three articles were analyzed that dealt with the subject discussed, which deepened the knowledge about it, human beings were not involved in the research, thus dispensing with the use of the free informed term. Results: The activities carried out by the brain define all the structures of the body. The patient's vital functions are freely and spontaneously linked and linked to the heart and lungs. The most common causes for the evolution of brain death are traumatic brain injuries (TBI) resulting from car accidents or physical aggression. The act of being an organ donor is characterized as solidarity with others. The family authorizes, however, the patient must agree in life with the act of donating their organs to other people. It is important to remember that not all patients who progress to brain death can be organ Faria et al.

Pressure injury is a localized damage to the underlying skin and / or soft tissue, usually on a bony prominence or related to the use of a medical device or other artifact. The lesion can appear on intact skin or as an open ulcer and can be painful. The injury occurs as a result of intense and / or prolonged pressure in combination with shear. Tolerance of soft tissue to pressure and shear can also be affected by microclimate, nutrition, perfusion, comorbidities and their condition. The objective of identifying the associated factors and preventive measures for pressure injuries in an intensive care unit, in order to support the professional in decision making to improve the care provided to these patients. The methodology is a narrative review study with an exploratory, observational, retrospective study approached in 07 articles in the databases (PUBMED, LILACS, BVS, SciELO, REBEN) between 2008to 2016 During the review, it was found that most pressure injuries could be avoided by taking simple actions such as changing the position, using pressure relief devices in areas of bone prominence, careful observation of the skin and greater knowledge by health professionals, making it necessary to qualify health professionals with regard to the main characteristics of patients who develop pressure injuries and risk assessment scales such as the Braden scale, with the possibility of making prognoses and, thus, prevent them. It is concluded that the majority
