title: Trauma deaths in the first hour: are they all unsalvageable injuries?
abstract: BACKGROUND
  With the advent of trauma systems, time to definitive care has been decreased. We hypothesized that a subset of patients who are in extremis from the time of prehospital transport to arrival at the trauma center, and who ultimately die early after arrival, may in fact have a potentially salvageable single-organ injury.
  
  
  METHODS
  We reviewed all deaths that occurred in the first hour after hospital admission. Trauma registry, medical records, and autopsy reports for 556 patients were evaluated.
  
  
  RESULTS
  The median time to arrival was 39 minutes, and the median Injury Severity Score was 29. Blunt injuries (53%) were most commonly auto-accident injuries (134 of 285 patients; 47%). Penetrating wounds (42%) were mostly gunshot wounds to the chest (73 of 233 patients; 31%). For patients with initial vital signs, the most common cause of death was isolated brain injury (26 patients; 28%). Possibly survivable injuries (single organ or vessel) occurred in 35 (38%) patients, of which 4 were isolated spleen injuries (4%).
  
  
  CONCLUSIONS
  Some patients with potentially survivable single organ injuries did not have associated head injuries. An aggressive approach is warranted on patients with detectable vital signs on at least one occasion in the field but who arrive at the trauma center in extremis.
