Prevention of Infection in War Chest Injuries

Abstract

Infection is a major complication of military chest injuries. In a series of 142 wounded, infectious complications occurred in 7 (4.9%). Factors influencing the incidence of infection are evaluated. In this group of injuries, 81 patients were admitted soon after wounding. The intrathoracic damage was severe, due to penetration of metallic fragment. The hemothorax was treated by immediate intercostal drainage. Immediate thoracotomy was performed in 10 patients and late thoractomy in 15. One patient developed a lung abscess and 5 patients had infection following thoracotomy (7.4%). Another 61 wounded patients had been first managed in a forward hospital, including three with thoractomy for massive bleeding. Two, not in a forward hospital, had a bullet removed from the lung. Upon admission to this hospital, intercostal drains were inserted when needed and four patients underwent thoracotomy. Larger wounds were debrided in 24 patients. Late thoracotomy was perfromed in seven. Chronic empyema developed in one patient after pneumonectomy performed at the field hospital, resulting in a resuscitation or infection rate of less than 2%. Factors contributing to a low infection rate were: early drainage of hemothoraces and wide debridement of larger wounds with delayed closure and avoidance of thoracotomy as primary treatment. Resection of lung tissue was avoided. Thoraco-abdominal injuries were treated separately. The clotted hemothorax was immediately evacuated. Prolonged antibiotic therapy was usually indicated.
