Bronchial smooth muscle spasm

Bronchial smooth muscle spasm is also called asthma. Bronchial asthma is short for asthma. The main pathological change is bronchial smooth muscle spasm, which is one of the common respiratory diseases in pediatrics. Bronchial asthma is currently considered to be a chronic inflammatory disease of the airways, and many cells play an important role in it, such as lymphocytes, eosinophils, mast cells, etc., accompanied by a marked increase in non-specific airway reactions. Airway hyperresponsiveness (BHR) is a multi-factorial disease with major clinical features. The clinical manifestations are mainly reversible episodes of wheezing and cough, chest tightness, and dyspnea. These symptoms are often reversible, but they can also cause severe death. Therefore, attention should be paid to the prevention and treatment of asthma.
