Cardiac injury due to accidental discharge of nail gun.

BACKGROUND Since 1991, the incidence of injuries associated with pneumatic and explosive powered nail guns has steadily been rising due to increasing use of these devices by the untrained consumer. The vast majority of injuries involve the extremities, but injuries have been reported to occur in virtually every area of the body. OBJECTIVE Discuss the epidemiology, pathophysiology, and management of penetrating cardiac nail gun injuries. CASE REPORT A 33-year-old man sustained a penetrating cardiac injury from accidental discharge of a nail gun. The patient had successful repair of a laceration to his right ventricle. CONCLUSIONS Penetrating cardiac injuries from pneumatic nail guns are rare and have mortality similar to stab wounds. Improved safety mechanisms and training are the keys to prevention. Consideration also should be given to implementing legislation restricting the sale of nail guns.
