Bipulmonary bronchitis is categorized into acute and chronic. Bipulmonary bronchitis with restrictive emphysema can be treated by medication, local therapy, and systemic therapy. Acute bipulmonary bronchitis with limited emphysema may be caused by viral or bacterial infections, viral infections are contagious, while bacterial infections are not contagious. If it is caused by bacterial infection, it can be treated with medicines such as cefuroxime and cefradine as prescribed by the doctor, and if it is caused by viral infection, it can be treated with medicines such as oseltamivir and ribavirin. Chronic bronchitis with restrictive emphysema may be caused by long-term smoking and exposure to harmful gases, which may cause bronchial stenosis and limited ventilation. Tiotropium bromide powder inhaler, salmeterol ticarcoson powder inhaler and other drugs can also be used to improve their airflow limitation, and aminoglutethimide, carbocysteine and other drugs can be used to alleviate cough and sputum symptoms. Patients with bipulmonary bronchitis with restrictive emphysema should quit smoking and drinking in daily life, eat less spicy and stimulating food, and seek medical advice if they feel unwell.
