Asthma is a common disease and many patients and parents are worried about asthma attacks, so how to reduce the number of asthma attacks? The following methods should have some preventive effect for asthma patients. A. Create a “family case” for the patient, including the date, time, place, severity, weather conditions on the day of attack, any special diet, exposure to special chemicals, medication, special events in life within 24 hours before the attack, whether there has been strenuous activity, whether there has been crying or laughing, etc. It should be recorded in detail, so that after a long period of patient and careful observation, analysis and generalization can identify certain patterns of the onset of the disease and related suspicious factors so that appropriate measures can be taken to avoid. Second, the ideal living environment for asthma patients: 1, choose a sunny room, keep the room clean and dry, smoking is strictly prohibited, bedding should try to use cotton fabrics, do not use the bedding pillow made of fur, silk, cotton or down, etc., to use foam instead of real stuff such as wood, cotton, pope and velvet 2, do not keep cats, dogs, rabbits, pigeons, etc. at home, and do not let these animals into the bedroom of asthma patients 3, do not use strongly scented 4, pay attention to the patient’s diet fish, shrimp, crab, onion, garlic, leek, too acidic and too spicy food to eat less. Third, develop good habits: 1, diet, sleep, urination and defecation should be regular, usually not full not to eat too salty or stimulating food 2, a certain amount of time every day outdoor activities, the content of the activities can be flexible according to the age of the smooth degree of breathing must not be afraid of asthma attacks and excessive restrictions on physical activity, asthma attacks when it is necessary to pay attention to rest, if asthma attacks have seasonal, to carefully observe If the asthma attack is seasonal, observe carefully what flowers and trees are blooming in the area during the attack season and reduce outdoor activities. Fourth, patients should have a correct understanding of the disease and know that with the joint efforts of patients and doctors, the symptoms of asthma can be completely controlled with the correct treatment, which can reduce attacks, reduce attacks, or even no attacks, reduce hospitalization or no hospitalization, reduce outpatient visits, and minimize missed work and school. In the remission period, it is completely possible to live the same life as normal people and even participate in physical exercise to enhance the confidence of fighting and overcoming the disease. V. Work closely with medical staff and establish partnerships. Actively participate in activities organized for asthma patients to raise awareness of the nature of asthma disease and methods of prevention and treatment. Master certain diagnosis and treatment techniques, such as the correct use of peak flowmeters, self-judgment of the disease, and the correct and rational use of drugs, such as the use and dosage of aerosols. Sixth, do not have a disease, simply can not listen to the lies of social quackery can cure. Do not use the socially indiscriminate preparation of counterfeit and fake drugs to avoid serious adverse reactions. Seven, the hormone inhalation therapy to have the right understanding, many patients think that the adverse effects of hormones are too much, refused to accept the treatment of aerosol. Because the current drug for the treatment of tracheal inflammation is mainly hormone inhalation aerosol, with certain efficacy, unlike oral agents, aerosol inhalation directly into the trachea, the dose is very low, rarely inhaled by the body, so long-term use will not appear obvious adverse reactions. As long as the treatment can be adhered to will receive good results.
