The experience of treatment of 224 patients with pulmonary bleeding after the blunt thoracic trauma were analyzed. All patients were diagnosed with lung contusion, of them 134 had traumatic cavities (hematomas) in the lung. The complete regression of contusion foci was observed within 13.7±4.2 days, whereas only 65.4% of patients demonstrated the regression of lung hematomas after 3 months of follow-up. 5.36% of pulmonary bleeding required the urgent thoracotomy on the reason of the continuous bleeding. The thorough analysis of etiology of posttraumatic infectious pulmonary complications after the blunt thoracic trauma is submitted. The drainage of septic foci allowed the fast recovery of the majority of patients. 7,4% of lung abscesses and pleural empyem required thoracotomy.
