Tracheostomy Exchange Resulting in Rare Combination of Pneumomediastinum, Pneumothorax, Massive Pneumoperitoneum, and Subcutaneous Emphysema

: Tracheostomy tube change is a relatively common and simple procedure once a tract is formed between the skin and the trachea. Regular tracheostomy tube changes decrease the risk of postoperative pulmonary infection and granulation tissue formation. However, serious complications, such as loss of airway, subcutaneous emphysema, and mediastinitis, can occur if the tube exchange is performed inappropriately. We present a rare association of subcutaneous emphysema, tension pneumothorax, pneumomediastinum, and pneumoperitoneum following a tracheostomy tube exchange in a 56-year-old patient who had his tracheotomy placed a month ago. The patient was successfully managed conservatively by chest tube and supportive care.
