【 摘 要 】

BackgroundThe analysis of patterns of trauma deaths may improve the evaluation of a trauma system and identify areas that may benefit from more resources. The objective of this study was to analyze the epidemiology of trauma deaths in a Brazilian university hospital in order to assess the profile of these fatalities over a 16-year period.MethodRetrospective study of time series using database records. The research subjects were in-hospital deaths from external causes during the years 1995, 2000, 2005 and 2010. The following variables were analyzed: cause of injury, trauma scores, time and cause of death.Results467 cases were studied, being 325 patients (69.6%) admitted with signs of life and 142 (30.4%) considered dead on arrival. The mean age was 35.35 ± 18.03 years. 85.4% were males. Blunt trauma occurred in 73.0% of cases and penetrating mechanism in 27.0%. There was a significant increase (p < 0.001) in deaths from motorcycle crashes over the years, which went from 7.3% in 1995 to 31.5% in 2010. In contrast, there was a significant decrease (p = 0.030) in firearm-injury victims; from 21.0% in 1995 to 9.6% in 2010. About 60% of deaths occurred less than 24 hours after admission. The main causes of death were lesions of the central nervous system (56.3% of the total), followed by hemorrhagic shock (18.1%) and sepsis/multiple organ dysfunction syndrome (17.1%). The mean Injury Severity Score (ISS) of patients with signs of life was 26.41 ± 9.00, 71.3% of whom had ISS >25. The mean Revised Trauma Score (RTS) was 5.24 ± 2.05. Only 25.8% of the deaths had TRISS <0.50.ConclusionThere was a shift in the profile of causes of death from trauma in this university teaching hospital, with a large decrease in penetrating injuries and a higher incidence of deaths of motorcycle riders.
