Which term describes gas in soft tissues that distends them?

• A. subcutaneous emphysema
• B. bacterial translocation
• C. agonal dehydration
• D. agonal edema

Answer: (A)

Gas distending soft tissues is called subcutaneous emphysema. Emphysema in this context means air or gas trapped within the subcutaneous tissue layers, causing swelling and a crackling sensation when you press on the skin. It most often arises after trauma that lets air enter tissue planes, from surgical or dental procedures, from a pneumothorax with air tracking into the chest wall, or from infection with gas-forming organisms. Recognizing this finding helps point to an underlying injury or source of air that may need evaluation. Bacterial translocation refers to bacteria moving from the gut to normally sterile areas, not gas in tissues. Agonal dehydration and agonal edema describe fluid status and swelling around the dying process, not gas distension of soft tissues.
