Penetrating chest trauma: a 20-year experience.

From 1965 to 1985, 76 patients were admitted to Sacré-Coeur Hospital, Montreal, with a diagnosis of penetrating chest trauma (PCT). The majority were under the age of 30 years and almost two thirds suffered gunshot wounds. Sixty-seven (88.1%) sustained a lateral or thoracic (T) injury and in nine (11.8%) the lesion was central or mediastinal (M). In the first group (T), 53.7% were treated surgically with thoracotomy, laparotomy, and chest tube (CT) insertion or both; 46.2% were managed conservatively. In the second group (M) the pericardium or the heart was involved, eight patients (88.8%) were managed surgically without the use of extracorporeal circulation and one patient was observed only. Eight (11.9%) died in the thoracic group; all survived in the mediastinal group, for an overall mortality of 10.5%. Shock was associated with increased morbidity and mortality in the thoracic group (T) and infection was the most frequent complication for the entire group of patients under study. There has been a steady increase in the total number of PCT at our hospital during the last two decades suggesting an increase in crime and violence in our urban surroundings.
