Patients with pulmonary nodules need surgical treatment, and there are some sequelae left after the completion of surgery, such as infection, postoperative bleeding, postoperative pulmonary atelectasis, postoperative pneumothorax, etc. Some of them can cause persistent failure to remove the tube, and patients become infected, coughing, coughing, fever and other symptoms, which need anti-infection treatment. If the air leak is more serious, even mucolytics or secondary surgical treatment is required. The most serious thing is postoperative bleeding, a small amount of postoperative bleeding can be treated with drugs, if the bleeding is more obvious, some of them have to undergo a second surgery. Generally, after surgery for pulmonary nodules, because the nodules are relatively small, the impact on lung function is not good, but some patients will feel a little bit of chest tightness and shortness of breath when they move around. The pathological results of the nodules will be used to determine whether further treatment is needed after surgery.
