Abstract

Introduction: Empyema remains a potentially serious condition with multiple etiologies including post-pneumonic, post-resection, and post-traumatic. There are few studies describing the latter. We reviewed our experience at a high volume trauma centre in injured patients with empyema, examining pre-operative status, surgical procedures, pathogens and outcome. Methods: Retrospective trauma registry review, from 9/01 to 4/10. Empyema was defined as culture positive pleural fluid or purulence at operation. Data collected included demographics, injury mechanism, thoracic injuries, organ dysfunction, pathogens isolated, surgical procedures, outcomes and follow up. Results: One hundred twenty-five consecutive patients with empyema were identified. Average injury severity score and age were 27.3 and 37.2 years respectively; 89.6% were male, 63.2% sustained blunt chest trauma. Time from injury to diagnosis averaged 12.1 days. All underwent decortication; 80% by thoracotomy, the remainder thoracoscopically. At operation over half were mechanically ventilated and 13.6% required vasoactive infusions. Monomicrobial cultures with Gram positive cocci predominating were obtained in 44%, 48% had polymicrobial cultures and 18.4% had a ruptured lung abscess. There were five deaths (4%); two occurring after a ruptured lung abscess. Recurrent empyema occurred in 6.4%, all successfully treated by re-operation or catheter drainage. Intensive care and hospital stays were 18.1 and 30.6 days respectively. All survivors achieved resolution of empyema. Conclusions: Trauma patients with empyema represent a subset of severely injured critically ill patients with diverse pathogens and polymicrobial flora. Appropriate surgical management and specific antibiotic therapy yields excellent results with acceptable risk. A ruptured lung abscess may be the aetiology of the post-traumatic empyema in a subset of patients and may represent an increased operative risk.
