They cause a mortality of 5% in the first month, joined to the complications derived from immobilization. (GAMMA, 2008). Frequent, in the falls of the aged ones, it ahead has inefficacy of some of the defensive mechanisms of such situation (extension of the arms, for example). On the other hand, the possibility of that causes serious injuries is very bigger of what in young. The fall can cause since cerebral official corruptions the acute subdurais hematomas with necessity of surgical intervention. Approximately 50% of aged that they suffer the falls need aid to arise themselves and about 10% they remain in the ground during long time. The related factors of risk with the permanence in the ground, are the superior age the 80 years, the functional dependence, the reduction of the force in inferior members, upheavals of the balance, amongst others. (GAMMA, 2008) the permanence in the ground during long time can provoke dehydration, vomits, diarrias and taquipnia.
The hipotermia appearance is possible, since it is a picture of superior frequency what it is thought, and with serious complications. The subagudos or chronic subdurais hematomas can appear for minimum traumas and attend a course with little specific sintomatologia. (GILLESPIE, 2008) the passed time between the fall and the appearance of the sintomatologia (15-30 days), makes it difficult the diagnosis. They are most frequent in the aged patients. In gnese of a fall in an aged one it is habitual to find diverse factors incriminated in greater or measured minor. The individualizada etiolgica inquiry is basic in the adoption of efficient writs of prevention. The risk factors can be classified in three categories: intrinsic, extrinsic and mannering. Intrinsic factors are those inherent characteristics to the individual. The extrinsic factors include ambient perigos, bemcomofatores related to the activities. Gamma (2008) made a study with the objective systemize the findings of the studies of prospectivos coorte on the multiple factors of risk of aged falls in and evaluating the metodolgica quality of these studies.
