What Is Subcutaneous Emphysema?

The subcutaneous tissue of the chest is called subcutaneous emphysema when the volume of air is stored. Pressing the skin of the subcutaneous emphysema with your hand can cause the gas to move in the subcutaneous tissue, and a twisting feeling or a snowy feeling can occur. When you press the subcutaneous emphysema with a stethoscope, you can hear a sound like twisting your hair. Subcutaneous emphysema in the chest is mostly caused by the escape of gas from the lesion after the lung, trachea, or pleura is damaged, and it accumulates under the skin. Occasionally occurs in local aerobic infection. In severe cases, the gas can spread from the chest wall subcutaneously to the neck, abdomen or other parts.

This morbidity is caused by improper management and rough catching, causing the neck airbag or subclavian airbag to rupture, or the puncture of the airbag by other sharp objects, causing the gas to leak under the skin and forming subcutaneous emphysema. In addition, it can also be caused by humerus, coracoid, and sternum.

The neck balloon is ruptured, showing that the feathers of the neck are inverted. The lighter emphysema is confined to the base of the neck. The severer can extend to the upper part of the neck, and the air bubbles appear in the lower part of the tongue band. If the abdominal balloon ruptures or is caused by

Generally, patients with subcutaneous emphysema have no conscious symptoms, but the effect on the patient is difficulty in opening eyes. Patients with mediastinal emphysema often complain of chest tightness or

Generally, no special treatment is needed for subcutaneous emphysema, but the source of gas should be controlled in time, including the drainage of pneumothorax, and surgical treatment of tracheal, bronchial, lung or esophageal injury. If these causes of emphysema are removed in time, subcutaneous emphysema can often be absorbed by itself within a few days. Once the pressure in the mediastinum increases significantly, symptoms of dyspnea and neck venous congestion appear, mediastinotomy and drainage should be performed in time. The surgery was performed under local anesthesia. A transverse neck incision was made at the upper edge of the sternal notch. The muscles and fascia were separated, and the anterior wall of the trachea was exposed. The index finger was pressed against the trachea wall and bluntly separated down to the level of the aortic arch. The roots are thick and not easy to collapse, and the drainage tube beside the end tube is porous. Finally, the neck skin incision is loosely sutured.

After the occurrence of subcutaneous emphysema, the needle can be used to puncture the skin of the swollen part to release the gas, but it will swell soon, and it must be deflated several times before it can work.
