The degree of air leakage after lung surgery can be determined based on closed chest drainage, which on the other hand can drain the gas to promote healing.
Air leakage after lung surgery can be caused by poor intraoperative suture closure, dislodged surgical sutures, and dislodged metal wire cards, which can lead to pneumothorax and subcutaneous emphysema after lung surgery. Therefore, closed chest drainage is usually performed after lung surgery.
The degree of air leakage can be roughly determined based on the frequency, duration, and volume of gas expelled by closed chest drainage.
In addition, closed drainage prevents life-threatening pneumothorax from compressing the lungs and promotes healing of the fistula after the gas is drained.
The surgery should be performed by a specialized physician and the patient should be treated if there is any discomfort.
