Tracheal chirping and white sputum without coughing may be caused by trachea-bronchitis, bronchial asthma and other diseases, which need symptomatic and causative treatment. 1. Tracheo-bronchitis: Tracheo-bronchitis can be caused by biological, physical and chemical stimuli or allergies, etc. It can be manifested by bronchospasm and increased secretion, which leads to narrowing of airway lumen, and the chirping sound can be produced when the airflow passes through the narrowed area. Expectorants such as Ambroxol and Bromhexine need to be taken, and antibiotics such as Cefixime can be taken to fight infection if there is bacterial infection. 2. Bronchial asthma: Bronchial asthma is a heterogeneous disease characterized by airway hyperresponsiveness, which is mainly manifested by episodic coughing, wheezing and dyspnea, and rales can often be heard during the episodes. Inhaled glucocorticoids combined with beta2 agonists are commonly used to control the disease, such as budesonide formoterol powder inhaler. In addition, there are other diseases that can cause the symptoms of airway rales and white sputum without coughing. If the symptoms are not relieved or aggravated, it is necessary to consult a doctor as soon as possible to clarify the cause of the disease and follow the doctor’s instructions for rational drug treatment.
