210 cases of septic complications after blunt thoracic injuries were analyzed. Pleura empyem was observed in 172 (1,34%) of 12874 patients (overall number of the injuried), lung abscess - in 48 (0,37%) cases, pericarditis was diagnosed in 33 (0,23%) patients, costal and sternal osteomyelitis - in 21 (0,16%) and mediastinitis - in 14 (0,1%), thoracic wall phlegmona in 50 (0,39%) patients. Overall frequency of septic complication was 2,96%. Main reasons of septic complications were: massive blood loss (55,7%), late diagnosis and hospitalization (54,8%), long - lasting and coagulated hemothorax (38,1%), pulmonary bleeding (20%) and secondary infection, including multiple (29%) and prolonged (10,5%)pulmonary drainage. Staphylococcus aureus was the most frequent microbe detected - 44,3%. Lethality rate was 13,8% (29 patients). Adequate drainage of the wound allowed curation of the majority of patients. Chronic purulent forms, requiring major surgical treatment were registered by the pleura empyem in 9,3%, and by the lung abscess in 10,4%, by costal ostheomyelitis - in 52,4% of cases.
