Bronchial Asthma

Bronchial asthma is and episodic allergic pulmonary disease. The attack is mostly induced by the inhalation of or contact with allergens, such as pollens, dusts, insects (such as mite), germs, etc. During the attack, patients have severe dyspnea which is due to spasm of bronchial smooth muscles, swelling of the bronchial mucosa, and hypersecretion of the mucus, leading to bronchial obstruction. When the attack can not be relieved for a long time, it is called "status asthmaticus." The disease is often seen in children and teenagers. In TCM, it is attributable to the categories of "xiao" (bronchial wheezing) and "chuan" (dyspnea).

Main Points of Diagnosis
1. Notice whether there is an allergic history of the patient and his family. For patients with histories of allergic rhinitis and urticaria, the disease is easy to be diagnoses.
2. The onset is abrupt, frequently occurring at night. Usually the patients suddenly have a sense of suffocation and of constriction in the chest, and orthopnea. The attack lasts from several minutes to several hours. On auscultation, typical wheezes can be heard over the lung fields. Moist rales may be present if pulmonary infection coexists. Termination of the episode is frequently accompanied by a cough with profuse mucoid sputum.
3. The status asthmaticus: In some cases the acute attack may persist for a long time (over 24 hours), or the episode can not be relieved by various drugs. The patients have severe dyspnea, accompanied with profuse sweating, pallor, cyanosis, tachycardia and coldness of limbs. Respiratory failure may occur in critical cases, and death may ensue if timely treatment is not given.
4. Laboratory examinations: The eosinophilic leukocyte count may increase markedly during the attack, up to 5-15 percent or more in differential count. Sputum examination may reveal more eosinopilic leukocytes and rhomboid crystals in the sputum. Serum concentration of IgE may be increased. Skin test for specific antigens is helpful to find the allergic agent, but the provocative allergic test may have potential danger of inducing asthmatic attack. Therefore, it should be performed with caution.
