Abstract
Since 1970 all patients admitted with penetrating injuries near the cardiac silhouette are transferred immediately to the operating room for resuscitation and evaluation for immediate thoracotomy. The clinical courses of 10 patients with penetrating cardiac injuries treated between 1962 and 1969 were analyzed and compared with those of 33 patients who presented between 1970 and 1977 and were managed more aggressively. Since the institution of this more aggressive policy, overall survival has improved from 20% to 67%. In patients arriving in the emergency room with signs of viability, survival increased from 29% to 76%. Of 53 patients with injuries in the area of the cardiac silhouette, 33 (62%) actually sustained cardiac injury. The high probability of cardiac injury in patients with external wounds in the silhouette and the improved survival rate seen with aggressive surgical therapy justifies the change to this policy.
