Chest injuries account for about 15% of war injuries [1], and the main cause of wartime mortality and morbidity is chest injuries [2]. The consequences of penetrating thoracic injuries can be serious, and mortality can occur at the scene especially if this situation is a result of a gunshot wound. Mortality can sometimes occur, specifically as a result of sepsis, in the late period. Noting this can make prudent intervention possible during the first response and enable a solution to the problem even before it happens. There might not be enough time, however, for a second intervention for complications related to existing injuries in extraordinary situations like war, and the picture may easily result in mortality.The 23-year-old male patient had initially received left anterolateral thoracotomy, pneumorrhaphy, and tube drainage procedures in Libya because of a penetrating gunshot wound in the left lung during the civil war. The patient was referred to our clinic with a picture of sepsis on the 17 th post-operative day for advanced treatment. The patient's presenting general condition was bad, his consciousness was somnolent, he was hypotensive, tachycardic, and tachypneic with axillary fever of 38.9°C. He also had bilaterally extensive subcutaneous emphysema which was more pronounced in the left thorax. Respiratory sounds could not be heard in the left lung through auscultation. The thoracic tube placed in the middle of the current thoracotomy line of the patient was not oscillating at the time of presentation. There was pus at the entry point of the tube into the skin and in the inner wall of the tube. The results of the thoracic x-ray and the thoracic computed tomography (CT) performed by us on the day of the patient's presentation at our clinic revealed left pneumothorax, pneumomediastinum, atelectasis, multilocular 6 × 4.5 cm intraparenchymal upper left lobe, infected hematoma with air value, segmental fracture in the posterior left 5 th rib (Figures 1 A, B), and extensive pleural effusion. Moreover, metal parts belonging to the gunshot wound were observed in the upper abdominal wall's left lateral part. His laboratory infection parameters were high (C-reactive protein (CRP): 26 mg/dl, leukocytes: 21500/mm 3 ). His drawn arterial blood gas showed signs of hypoxemia (pO 2 : 58 mm Hg) and hypercarbia (pCO 2 : 43 mm Hg), which suggested pulmonary organ failure. Furthermore, the patient was receiving totally parenteral nutrition (TPN) from the central venous pressure (CVP) catheter. Reoperation was planned from the pa-
