OBJECTIVE: To investigate the clinical epidemiological features. of blast injury of lungs caused by gas explosion. METHODS: A retrospective analysis of 132 cases of blast injury of lungs caused by gas explosion injuries in our hospital from 1990 to 2010 were made, including the information of lung injury, associated injuries, treatment and mortality. RESULTS: 56 patients were conscious on admission, during 1 ∼ 5 days, 30 patients got cough, hemoptysis and other pulmonary symptoms, 7 patients had hemothorax, 11 cases combined with pneumothorax, 86 cases of patients with burns, 96 cases with pulmonary aspiration compound injury, 41 cases with abdominal organs blast injuries, 76 cases with pulmonary infection, 31 cases with shock, Seven patients died of respiratory failure, two patients died of respiratory failure. CONCLUSION: Blast injury of lung featured with serious internal injuries, combined with many injuries, The incidence of compound injury was high, and it was difficult to diagnose. Chest X-ray were varied. The mortality was high, and the predominant causes of death were respiratory failure, shock, sepsis. Most patients with blast injury of lung need tracheotomy and mechanical ventilation. Timely tracheotomy, mechanical ventilation were the major prognostic measures.
