subcutaneous emphysema
Air trapped in the subcutaneous tissue, creating a characteristic crackling sensation on palpation.
Full Definition
Subcutaneous emphysema occurs when air becomes trapped in the subcutaneous tissue layer beneath the skin. In emergency surgery, it often indicates pneumothorax, esophageal rupture, or airway injury. The condition creates a distinctive crackling or crepitant feeling when the affected area is palpated, described as similar to pressing on bubble wrap. Recognition is crucial as it may signal serious underlying thoracic or cervical injuries requiring immediate surgical intervention.
