[Thoracic stab wounds]

Stab wounds are the most common cause of open chest wounds in our setting, with an incidence far higher than either wounds caused by firearms or bull horns. We describe a series of 49 patients, 44 (89.8%) men and 5 (10.2%) women. Mean age was 31 years. The 49 patients had suffered 72 stab wounds to the chest, of which 30 (41.6%) were penetrating and 42 (58.3%) were non penetrating. The lesions observed were 11 (22.4%) cases of pneumothorax, 10 (20.4%) of hemopneumothorax, 6 pulmonary lesions, 2 heart wounds and 1 extensively damaged diaphragm. Twenty-four patients with non penetrating wounds and 8 with penetrating wounds were treated conservatively. It was subsequently necessary to drain the chest of only one. Of the remaining penetrating wounds, drains were inserted in six immediately and 11 underwent surgery. Complications developed in only 9 cases. One patient died as a result of abdominal lesions resulting from stab wounds directly to the abdomen. We are in favor of conservative management. Indications for more aggressive intervention are hypovolemic shock, cardiac tamponade or significant loss of fluid through the thoracic drain.
