title: Penetrating chest injuries in the firearm era.
abstract: BACKGROUND
  firearm wounds of the chest are now common at our institution. The management algorithm for firearm wounds has not been evaluated for this mode of injury.
  
  
  METHODS
  records of all patients with penetrating chest injuries admitted to an urban tertiary hospital over 1 year were retrieved and analysed.
  
  
  RESULTS
  there were 473 stab and 116 firearm wounds. In comparison to stab injuries firearm wounds had significantly more normal X-rays (14 vs. 5%), fewer pneumothoraces (15 vs. 37%), and more contusions (43 vs. 2%). The frequency of haemothoraces (34 vs. 23%) and haemopneumothoraces (36 vs. 35%) was similar in both groups. Stabbing caused all the 18 cardiac injuries. Associated abdominal injuries occurred in 8% of stab and 34% of firearm injuries. Pneumothoraces due to firearms were uncommon and rarely required drainage. More pneumothoraces were treated nonoperatively among firearm injuries in contrast to stabbing injuries where the opposite applied. The management of haemothorax and haemopneumothorax was similar in both groups that fulfilled the criteria for drainage. The rate of ICU admission was higher and the hospital-stay longer following firearm injuries. Fifty-nine patients died (10% of the total), 33 (28%) from the firearm injuries and 26 (6%) from stab-wounds. Early deaths were 1 and 3% for stabs and firearms, respectively.
  
  
  CONCLUSIONS
  patients with firearm injuries reaching hospital suffered three times higher mortality and a longer ICU and hospital stay than those with stab injuries. However, early mortality was similar for both modes of injury and validates the continued application of the stab wound derived management algorithm to all modes of injury.
