Acute bronchitis is a common clinical disease, which is an inflammatory bronchial infection caused by bacteria, viruses or other physicochemical factors. Acute bronchitis is divided into two types: simple and asthmatic, and asthmatic bronchitis is also called wheezing bronchitis. In addition to anti-inflammatory, cough suppressant, phlegm and other treatments, acute asthmatic bronchitis is also treated with antispasmodic and wheezing treatment, because patients in this category tend to wheeze and can be given salbutamol or even glucocorticoids for antispasmodic and wheezing treatment. Patients often have a combination of airway hyperresponsiveness, and attention should be paid to whether the patient has a family history of bronchial asthma or a history of similar attacks.
