Lung herpetic surgery is a routine surgery in thoracic surgery, and the postoperative care of lung herpetic is mainly the care of closed chest drainage tube and the care of assisting the patient to strengthen the lung function exercise. The care of thoracic drainage bottle is very important after the operation, because it is necessary to observe the fluctuation of the water column of the thoracic water flow, the overflow of air bubbles, and the situation of the drainage fluid in a timely manner. If the range of fluctuation of the water column is relatively large, consider whether there is a residual cavity in the lungs, and whether the lungs have not been completely opened. If there are more air bubbles, consider whether the stump of the lung is leaking. If there is more fluid buildup, look for bleeding. There are many reasons for persistent air leakage in the lungs, usually improper surgical management, advanced age combined with chronic obstructive pulmonary disease or emphysema, patients with long-term glucocorticoid application, and malnutrition. Secondly, assist the patient to strengthen the care of pulmonary function exercise, assist the patient to pat the back of the cough, cough sputum exercise.
