Contents and diagnosis of subcutaneous emphysema
Subcutaneous emphysema is usually asymptomatic, but can cause weakness, shortness of breath, tachycardia and hypotension, and a feeling of fatigue after exercise. In this case, the skin in the affected area swells significantly, the skin color changes from white to yellow, and with severe inflammation (emphysema), it becomes cyanotic. Less commonly, fever and a local increase in temperature may occur. In severe forms, pneumonia, bronchitis often occur, and hemorrhages and necrosis may occur. Changes in the respiratory organs manifest themselves in the form of wheezing, cough (usually wet), and weakening of breathing is noted on auscultation. The affected area cannot be determined by palpation; inflammation is determined only by the result of an external examination. Emphysematous lesions occur when alveoli rupture and are filled with air and exudate. When applying pressure with your fingers, the tissue of the affected area is damaged, local swelling is observed, and a purulent substance is released.
