1.To determine the diagnosis, to see if it is allergic asthma, generally through the medical history and allergen detection methods can be diagnosed, and only when the inhalation allergen is detected can desensitization treatment. 2, the purpose of detecting allergens, (1) to find out the allergens that cause asthma, (2) prevention, found to be food to cause asthma attacks, must avoid food, can avoid asthma attacks, (3) treatment, found to be airborne allergens (inhalant allergens) cause asthma attacks, can be treated by desensitization, in order to achieve clinical cure. 3, the choice of allergen detection methods, the world is recognized that the skin test and prick method is practical, economic, reliable results, blood testing due to different manufacturers, the credibility of the results vary greatly, bioresonance instruments to check the allergen, the international recognition. It is not recommended for use in China. 4.Adapted to the type of desensitization treatment is chronic asthma, non-acute exacerbation, can be perennial, can also be seasonal 5.Adapted to desensitization treatment patient’s medical history and age, medical history is generally more than one year, some more than six months can also be, age, generally adults can, children should be more than 5 years old. 6, desensitization treatment methods, generally using subcutaneous injection desensitization treatment, 1-2 times a week. 7, injection desensitization treatment injection course, a course of treatment a month. 8, injection desensitization treatment, injection dose, generally use the method of increasing allergen dose and concentration, increasing allergen dose, 0.1 ml, 0.2 ml, 0.3 ml – 1.0 ml, increasing allergen concentration, starting from low concentration 10 times the concentration every month, after the disease control to maintenance concentration, maintenance phase can reduce the number of injections, generally changed to once a week, or once every two weeks, 20 days, 1-2 days. Once every 20 days, once every 1-2 months. The maintenance treatment time should be long, generally 2-3 years, the longer the time the better the effect. 9, the effect of desensitization treatment, generally 1-2 months to see the effect, some people 3-5 months to see the effect, desensitization treatment effect maintenance time varies from person to person, generally 3-5 years. 10, the cost of desensitization treatment, the use of domestic reagents about 100 yuan a month, imported reagents are more expensive, many people are not easy to accept the price. 11, the safety of desensitization treatment, after the injection of desensitization solution to observe 30 minutes, no other reaction before leaving. Most of the time, there is no reaction. Individuals who have reactions can recover after rest, but serious reactions have to be resuscitated. It is recommended to use domestic reagents for desensitization treatment, which is economical. Note: 1. Allergic rhinitis can also be adapted to desensitization therapy. 2.Where the desensitization treatment of asthma patients, at the same time can also treat the patient’s other allergic rhinitis, allergic dermatitis, and so on. 3, desensitization treatment of asthma can be combined with other methods of immune regulation. Levamisole, inosine tablets, chaste qi punch, astragalus, heshu, jujube, wolfberry, bronchitis vaccine, polymyxin, thymidine, transfer factor, etc. 4.Bioresonance desensitization treatment is not recognized. 5.Food allergy treatment does not require desensitization injection.
