Treatment of Subcutaneous Emphysema

Initial Assessment and Stabilization

The American College of Physicians recommends immediately assessing for signs of respiratory distress including stridor, accessory muscle use, tracheal tug, and sternal/subcostal/intercostal recession in patients with subcutaneous emphysema 1, 3
Evaluate airway patency through clinical examination and suction if tracheostomy is present, as suggested by the American Thoracic Society 1
Use waveform capnography when available to detect early airway obstruction, as recommended by the American Association for Respiratory Care 2, 3
Monitor vital signs continuously including respiratory rate, heart rate, blood pressure, oxygen saturation, and level of consciousness, according to the American College of Chest Physicians 2

Obtain chest radiography to detect pneumothorax, pneumomediastinum, or other thoracic injuries, as recommended by the American College of Radiology 4, 3
Consider CT scan with contrast for detailed assessment of injury extent and air collection, as suggested by the Society of Thoracic Radiology 3
Check inflammatory markers (white blood cell count, C-reactive protein) to evaluate for infection, according to the Infectious Diseases Society of America 3
The British Thoracic Society recommends inserting a small-bore chest tube (10-14F) for pneumothorax, as there is no evidence that larger tubes (20-24F) are more effective 5, 3

The American College of Emergency Physicians recommends emergency intubation following Difficult Airway Society guidelines in situations of severe airway compromise unresponsive to initial measures 1
Perform cricothyroidotomy with scalpel-bougie-tube technique (preferred over cannula cricothyroidotomy) if unable to intubate or oxygenate, as suggested by the American College of Surgeons 1

The American Heart Association recommends immediate escalation for signs of mediastinitis including severe sore throat, deep cervical pain, chest pain, or dysphagia 2
Inability to maintain adequate oxygenation or ventilation requires immediate attention, according to the American Thoracic Society 1

The Society of Critical Care Medicine recommends avoiding clamping chest tubes that are still bubbling, as this can convert a simple pneumothorax into life-threatening tension pneumothorax 5, 3
Ensure proper aseptic technique during any invasive procedure to minimize infection risk, as recommended by the Centers for Disease Control and Prevention 5, 3
