Subcutaneous emphysema

Definition:

Subcutaneous emphysema occurs when air gets into tissues under the skin covering the chest wall or neck. This can happen due to stabbing, gun shot wounds, other penetrations, or blunt trauma.



Alternative Names: Crepitus; Subcutaneous air; Tissue emphysema

Considerations:

Subcutaneous emphysema can often be seen as a smooth bulging of the skin. When a health care provider feels (palpates) the skin, it produces an unusual crackling sensation as the gas is pushed through the tissue.



Common Causes:

This is a rare condition. When it does occur, possible causes include:

  • Pneumothorax (collapsed lung)
  • Ruptured esophagus
  • Ruptured bronchial tube


Home Care:



Call your health care provider if:

Most of the conditions associated with subcutaneous emphysema are very severe and require hospitalization. Medical staff would already be involved in most cases.



What to expect at your health care provider's office:
