1, shortness of breath, dyspnea, normal lung tissue is functional, removal of lung tissue will certainly appear shortness of breath and dyspnea, the severity is related to the amount of lung tissue removed, the quality of their own lung tissue, lung function, whether there is chronic obstructive pulmonary (such as asthma, slow branch, emphysema), age, etc.. The best adaptation is usually possible about 2 years after pneumonectomy. You can do some activities such as walking and tai chi for 1 month after lung lobectomy, and gradually increase the amount of exercise. Total lung resection is not recommended to do physical exercise and avoid strenuous activities.2. Cough, cough is the most common symptom after pneumonectomy. It may be related to tracheal intubation, tracheal sutures, tracheal traction, etc. causing tracheobronchial hypersensitivity state. Sometimes patients can talk to cause paroxysmal coughing, and coughing can aggravate dyspnea. Generally, the cough will gradually improve (about 3 months), and the severity of the cough is not exactly the same for everyone. Severe patients can take oral medications such as shunerin to reduce airway tension. 3, fever, normal patients may have a fever of about 38 degrees for about a week, pleural effusion after the drainage tube is removed almost every patient will have, about a month may appear low fever is normal, at this time the white blood cells should be normal. 4.Irritability, anxiety and even depression. We have encountered patients who appeared to suspect the failure of surgery after surgery and stayed up all night, and their family members did not do any consolation, but also poured oil on the fire. Finally, the patient improved after treatment by psychiatrist. The above symptoms need to be confirmed with the exception of surgical complications, especially pulmonary embolism, massive pneumoperitoneum and pus accumulation, bronchopleural fistula, and pulmonary atelectasis.
