What should I do if my trachea itches? Thank you for your questions.

Bronchial asthma is a common allergic disease. It can cause bronchial smooth muscle spasm, mucosal swelling and secretion increase due to the increased sensitivity of trachea and bronchus to various stimuli, resulting in tracheal stenosis. I. Etiology and Pathogenesis The etiology and pathogenesis of bronchial asthma are complex and have not been fully understood. At present, it is considered that allergy and autonomic nervous dysfunction are two main factors of asthma. 1. Allergic factors: In people with allergic constitution, after inhaling or contacting exogenous allergens, plasma cells produce corresponding specific antibodies IgE (reagin), which are adsorbed on mast cells in bronchial mucosa, small blood vessels in blood center and surface receptors of basophils, making people in an allergic state. When exposed to the corresponding allergen again, the allergen binds to the antibody on the surface of mast cells or basophils, activating a series of enzyme reactions of the cells, and releasing bioactive substances such as histamine and slow-response substances in mast cells or basophils. These bioactive substances stimulate the afferent part of vagus nerve, or directly act on bronchial smooth muscle, causing spasm, increasing mucosal edema and mucus gland secretion, leading to bronchiolar stenosis and asthma attack. 2. Nervous system factors: Bronchial asthma caused by nervous system factors is caused by increased susceptibility of vagus nerve receptors in bronchial submucosa, and is often induced by various stimuli such as respiratory tract infection, cold air and irritating gas. Common in adults. Second, the symptoms of allergic bronchial asthma may have an obvious history of allergen contact or be related to the season. Before the onset, there were many mucosal allergic manifestations such as itchy nasopharynx, itchy eyes, sneezing, runny nose and cough. Rapid onset, chest tightness, urgency and dyspnea are mainly caused by exhalation machine. Most patients were forced to sit up with their hands on the ground, their shoulders hunched and their foreheads sweated. In severe cases, dry cough and cyanosis may occur. It can be relieved naturally or through treatment. It often happens at night or in the morning. The incidence rate is 1%~ 1 1%, and the incidence rate and mortality rate have increased in recent years. Third, the harm of allergic bronchial asthma In the process of long-term recurrent attacks, the respiratory tract is damaged, the resistance is reduced, and it is easy to be complicated with respiratory infection, which gradually increases the infectious factors on the basis of allergic factors, complicates the symptoms and forms bronchial asthma. Such patients have a long medical history, often complicated with obstructive emphysema, and asthma often has no clear remission season. Persistent airway obstruction can cause pulmonary hypertension and pulmonary heart disease in addition to emphysema. Eventually it will lead to respiratory failure and circulatory failure. The most serious threat to asthma patients is sudden death. The patient suddenly had a severe and rapid asthma attack within minutes and hours, and died of respiratory and cardiac arrest before effective treatment. Fourth, the treatment and control of seizures, commonly used bronchial spasmolytics include theophylline and glucocorticoid drugs, such as aminophylline, ephedrine, hydrocortisone and so on. (1) Relieve asthma, inhale aminophylline or hormone aerosol (2) relieve cough and eliminate phlegm (3) treat with traditional Chinese medicine (4) treat with antibiotics when complicated with infection (5) treat with oxygen inhalation (6) treat asthma with fluid replacement to correct acidosis (7) treat with glucocorticoid, which is mostly used for patients with intractable asthma (5) prevent and care (/kloc-0) (2) Strengthen physical exercise appropriately to enhance physical fitness. Choose sports that suit you, such as climbing mountains and playing Tai Ji Chuan. (3) Enhance immune function. At present, the safest and most effective way to enhance immune function is to take targeted functional health products, such as OPC. Has the effects of scavenging free radicals, enhancing immunity and improving allergic constitution. (4) Dietotherapy, the diet should be light, eat less spicy and fried foods, and eat seafood and other foods that are easy to cause allergies carefully. (5) Keep an optimistic mood, don't be overly nervous and depressed, don't be overworked, and change bad living habits, such as smoking, drinking and irregular life. (6) Improve the indoor environmental sanitation. Underwear and bedding should be washed and dried frequently, and indoor air should be circulated. If you are allergic to pollen and cold air, you should pay attention to protect yourself in spring, autumn and winter. If it is pollen spreading season, do less outdoor activities, especially in parks. People who are allergic to cold air should wear masks when they go out in winter.
