Tracheoscopy in patients with bronchial tuberculosis is also the same as routine tracheoscopy. Bronchial tuberculosis patients are necessary to do bronchoscopy, first of all, bronchoscopy can do alveolar lavage fluid specimens and biopsy tissue in the trachea, for pathological testing, can further clarify the bronchial tuberculosis. At the same time, bronchial tuberculosis patients can observe the lesions in the trachea by bronchoscopy, and at the same time guide the clinical use of drugs, and also can be injected into the tracheal lumen of the drugs to assist in the treatment. And if there is a lot of sputum in the bronchial tubes, it can also be aspirated out by bronchoscopy. Tracheoscopy is necessary for patients with endotracheal tuberculosis, and it is important for patients with bronchial tuberculosis to follow the doctor’s instructions for regular treatment with anti-tuberculosis drugs, such as isoniazid, rifampicin, pyrazinamide and so on.
