[Penetrating thoracic injury]

To clarify the clinical aspects of penetrating thoracic injury.

Eighteen patients with penetrating thoracic injury treated from 1987 to 2005 were evaluated. There were 13 men and 5 women. The age distribution was 8 to 69 years, with an average of 36.7 years.

There were 14 patients with stab wound and 4 with impalement injury. Five patients with stab wound were those who attempted suicide. In 4 patients with impalement injuries, the cause was fall in 2, traffic accident in 1 and sports injury in 1. The calculated injury severity score (ISS) was over 15 in 4 patients, 6 to 14 in 12, and under 5 in 2. Thoracotomy was performed in 2 patients with cardiac tamponade, 3 with massive hemothorax and 1 with an impalement injury caused by an iron bar. All of them were rescued and got well. In the other cases, after cleansing and debridement, the wound was closed and thoracic drainage was performed. Only 1 patient with cardiac arrest on arrival died within 24 hours after reviving.

Emergent thoracotomy is indicated for patients with massive bleeding including shock, continuous air leakage and cardiac tamponade. Since cardiac arrest is difficult to cure, appropriate cooperation with the rescue team is necessary to avoid preventable trauma death.
