Bronchial asthma is a chronic respiratory disease in which patients suffer from recurrent episodes of wheezing and coughing, often in spring and autumn or after upper respiratory tract infections. The onset of asthma is closely related to allergic constitution. Although there is no complete cure for asthma, as long as patients master the correct asthma control methods. Asthma can be “completely controlled”. In other words, the quality of life and life expectancy are basically unaffected by the absence of discomfort. So, as an asthma patient or family member, how can we master the correct knowledge and methods of asthma prevention and treatment? Asthma is a chronic respiratory allergic disease, which cannot be cured at present, and can only be well controlled by adhering to long-term standardized treatment. Some patients do not want to receive the concept of long-term treatment and seek medical treatment everywhere in the hope of obtaining a cure for the disease, while some businessmen, travel doctors and even some medical practitioners in the society take advantage of the eagerness of such patients to make medical advertisements through some irresponsible media and promote the so-called “prescriptions and secret recipes” in order to make huge profits. In fact, these “prescriptions” often contain a large number of oral glucocorticoids and even immunosuppressants, which are indeed effective for short-term use, but long-term use, with many side effects, will aggravate the patient’s condition. This is tantamount to “quenching the thirst of the turtles”. Long-term treatment requires that patients should not only be satisfied with the remission treatment during the acute exacerbation period, but also the necessary maintenance treatment during the stable period of the disease, so as to slow down the progress of the disease and maintain a normal quality of life. Second, we should correctly master the use of drugs and objectively evaluate the adverse effects of drugs The core of asthma drug therapy is inhaled glucocorticosteroids, and recent studies have found that combined inhaled glucocorticosteroids and long-acting bronchodilators can maximize the control of asthma conditions. Some patients are concerned about the side effects of long-term glucocorticosteroid use and are therefore reluctant to receive such medications. Unlike oral and intravenous hormones, inhaled hormones have strong local anti-inflammatory effects, are used in low doses, and systemic side effects such as obesity, osteoporosis, and diabetes are rare. After nearly half a century and tens of millions of patients, inhaled hormones have been proven to be a very safe and effective drug, even for children and pregnant patients. Local airway inhalation is the most common way to administer asthma medications. Inhalation is a major feature of asthma treatment because of its direct action, rapid onset of action, low dosage and few side effects. However, the inhalation method is tedious and generally requires repeated demonstrations by the physician before the patient can master it. Sometimes clinicians are not responsible enough or they do not know how to use the medication, so they cannot teach the patients properly. After patients get the drug, they do not know how to use it, or use the wrong method, and do not get the proper efficacy, over time, they will lose confidence in this type of drugs. Therefore, patients must repeatedly ask the physician to learn the correct method of use before formally using inhalation preparations. Long-term treatment of asthma is not the same as long-term medication. Patients should learn to monitor their condition and adjust their medication according to the changes in their condition. How do I monitor my condition? This requires consultation with a professional physician. The condition cannot be based only on one’s subjective symptoms, as this is neither comprehensive nor objective. There are many asthma monitoring tools available, such as ACQ, ACT, and peak flow rate monitoring, that can help the physician and patient monitor the condition objectively and comprehensively so that medication adjustments can be made accordingly. This professional approach requires physicians to help patients at first, but as patients gradually master the knowledge of asthma control, they can try to monitor their condition and make treatment adjustments on their own. If an acute asthma attack is not treated in a timely and correct manner, it can cause great pain to the patient and even threaten his life. Therefore, for asthma patients and their families, it is necessary to master some knowledge of acute asthma attack rescue and treatment. 1.Emergency drugs Patients with asthma, regardless of how well their condition is controlled, should carry emergency drugs with them. A short-acting inhaled β2 agonist that works within minutes of inhalation is as important to asthma as nitroglycerin is to coronary heart disease, and can be life-saving at critical times. Patients should be skilled in its use (inhalation method) and change it regularly to prevent failure. However, this drug should only be used as an emergency medicine for acute asthma attacks, and should not be used regularly for a long time, because long-term regular use will lead to “drug resistance” in the respiratory tract, and it will not be able to play its proper role when it is really needed. 2.How to determine an acute asthma attack? Asthma attacks are usually urgent and are preceded by triggers, such as inhalation of certain allergens or irritating gases, or even after a common cold, itching of the nose and eyelids, tearing, frequent sneezing, runny nose, dry cough, followed by chest tightness, breath-holding, or even a sense of suffocation, and labored exhalation, forcing the patient to sit and rest, with a “whistling sound” in the airway. “. Asthma attacks have a certain seasonal and temporal pattern, such as good in summer and autumn, easy to attack or intensify at night or early in the morning. 3.First aid measures in case of asthma attack First, the patient should remain seated, loosen the clothespins, keep the surrounding environment well ventilated as much as possible, start oxygen inhalation if possible, and repeat inhalation of short-acting β2 agonists, 2 to 4 sprays every 20 min in the first hour. Subsequently, depending on the response to treatment, adjust to 2-4 sprays every 3-4 hours. If the patient has severe symptoms and is unable to inhale sufficient doses of medication, some devices such as storage jars can be used to assist. Most patients with mild attacks can be relieved after such simple treatment. For patients with moderate to severe attacks whose symptoms are still not relieved, they should enter the hospital for regular treatment as soon as possible. As a chronic respiratory disease that cannot be cured, asthma requires long-term standardized treatment and condition monitoring. Only then can complete control of the disease be achieved, i.e., maintaining the same quality of life as that of a healthy person, essentially symptom-free and without acute exacerbations.
