Spring is the high season of asthma, the main reasons are as follows: at this time, some flowers, trees, pollen and other allergens in the air in high concentrations; the weather hot and cold changes, hot and cold, easy to cause upper respiratory tract infections, and upper respiratory infections is an important cause of asthma; spring air is dry, sandy and dusty weather, the respiratory tract stimulation is greater. Therefore, for all asthma patients, spring asthma prevention should pay attention to the following aspects: dress warm, as the saying goes, spring cover autumn freeze is reasonable, pay attention to warmth, to avoid cold and flu to reduce the incidence of asthma important measures; pollen allergy patients to minimize the outing; in the weather dusty and heavy air pollution days to pay attention to the closure of windows and doors. But for the elderly asthma patients, just pay attention to the above aspects is not enough, because of the special physiological and pathological characteristics of the elderly, determines the onset of asthma in the elderly characteristics, prevention and treatment measures are different from children and adolescents asthma. First of all, asthma is a very common disease in the elderly, some medical research findings found that old age is the second peak period of asthma after childhood. However, because elderly asthma patients are often combined with other geriatric diseases, such as coronary heart disease, hypertension, chronic bronchitis, emphysema, diabetes mellitus, etc., and the symptoms of these diseases and asthma chest tightness, wheezing are very similar or overlap with each other, so that the diagnosis is more difficult, if not by experienced respiratory specialists to carefully examine, often easy to misdiagnosis. In our clinic, we often encounter some elderly asthma patients who have had a clear history of asthma for several years, but have been diagnosed as coronary heart disease, hypertension or chronic bronchitis and delayed effective treatment. Secondly, elderly asthma patients are often diagnosed with asthma when there has been significant damage to lung function, the degree of reversibility of lung function is also relatively low, which is partly due to the long-term delay in diagnosis and treatment, but also with the elderly respiratory organ function decline, respiratory function reserve capacity is reduced. This is all the more reason to remind the elderly to pay close attention to symptoms such as coughing and shortness of breath to see if there is a possibility of asthma, and it is advisable to seek medical attention in a timely manner, to confirm the diagnosis in time, and to treat the disease at an early stage, in order to have better protection of lung function and to ensure a good quality of life. Symptoms of asthma are mainly episodes of expiratory dyspnea with rales or episodes of chest tightness and coughing, usually a dry cough or coughing for a while and then producing white frothy sputum, and a whistling sound can be heard during exhalation. Asthma symptoms may flare up within minutes and resolve on their own over hours to days. Attacks and exacerbations at night and in the early hours of the morning are often a feature of asthma. In a few patients, an irritating cough may be the only symptom or may be accompanied by mild chest tightness. Older asthma and long-term smoking is more closely related to the presence of thousands of chemical components in cigarette smoke, such as tar, formaldehyde, arsenic, cyanide, benzene, toluene, carbon monoxide and so on. Tar contains a large number of toxic substances, can damage the bronchial mucosa, so that the risk of asthma greatly increased, many scientific studies have also proved that asthma and smoking related. Many elderly asthmatics are smokers, which is different from youth asthma. Young people or adults with asthma often have an aversion to smoking and cannot tolerate the stimulation of smoke. And some of the elderly asthma patients are long-term smokers, from the psychological and physiological already have a dependence on cigarettes, and some even wrongly rely on smoking to stimulate phlegm, this wrong practice, so that the smoking elderly asthma patients further aggravate the symptoms, deterioration, lung function destruction more rapidly. In addition, the elderly some common diseases of therapeutic drugs also have a relationship with the onset of asthma, such as the treatment of hypertension, coronary heart disease β-blocker may also induce or aggravate asthma; the elderly are prone to gastroesophageal reflux disease, especially at night there are trace amounts of gastric juice reflux was inhaled into the trachea – bronchus, but also an important factor in the triggering of asthma. Therefore, elderly patients with asthma should explain to the doctor when they visit the doctor for cardiovascular disease. If there is frequent acid reflux, belching (commonly known as spitting acid, burping) should seek medical attention. In recent years the treatment of asthma has made great progress, asthma has also become a chronic disease with better treatment effect, if timely diagnosis, regular treatment, long-term adherence to medication, it is completely possible to achieve good control, normal life, without affecting the life expectancy of the effect. The current medications for asthma are mainly divided into two categories: control medications and reliever medications. Control drugs: anti-inflammatory effect, through the treatment of asthma airway inflammation to control asthma symptoms and acute exacerbation of the purpose. This type of medication needs to be used regularly on a daily basis for a longer period of time. Inhaled glucocorticoids are currently the most effective drugs for suppressing airway inflammation and controlling asthma symptoms and acute exacerbations. Inhaled drugs act directly on the airways, have high local concentrations, strong anti-inflammatory effects, require smaller doses, and have fewer systemic adverse effects. Commonly used inhaled glucocorticoids include beclomethasone propionate, budesonide and fluticasone propionate. Regular inhalation for more than a week is usually required to produce a significant effect. Palliative drugs: mainly bronchodilators. Short-acting β2 agonists such as salbutamol and terbutaline dosing aerosol are mainly used for temporary relief of acute asthma symptoms and should not be used alone for a long period of time. The long-acting β2 agonists salmeterol and salmeterol diastolic bronchial smooth muscle effect can be maintained for more than 12 hours. Anticholinergics such as ipratropium bromide and tiotropium bromide have both bronchodilating and sputum-reducing effects, and are particularly suitable for patients with nocturnal asthma and phlegm. Combinations of inhaled glucocorticoids and long-acting β2 agonists, such as fluticasone/salmeterol and budesonide/formoterol, are more effective and are now the drugs of choice for the majority of patients with chronic, persistent asthma who have symptoms year-round. Asthma sufferers often ask, can asthma be cured and eliminated? How long does inhaled therapy take? Do I need to continue treatment if I am symptom-free for a period of time? Is it better to use Chinese medicine or western medicine to treat asthma? Are there any side effects of long-term hormone inhalation? At present, after a large number of clinical medical scientific research, the answer to these questions is: 1, asthma is a disease related to heredity, the current level of scientific and technological development of mankind is not yet a cure for asthma, all the propaganda and advertisements claiming that asthma can be cured are deceptive, is not credible, but there are some children with asthma symptoms in the adult, untreated can be a long time or even years and decades of stable non-attacks. 2, about the course of inhalation therapy, the current study that, for those chronic persistent asthma patients with symptoms in the past years, by inhalation fluticasone/salmeterol, budesonide/formoterol treatment, after good control of asthma symptoms, but still continue to use the drug should not be less than half a year, and then under the guidance of the doctor to reduce the amount of, the total duration of the course of treatment should not be less than 2 years. 3, the current asthma treatment has made significant progress, mainly because of the successful development of inhaled glucocorticosteroids and inhaled long-acting bronchodilators, inhaled glucocorticosteroids and inhaled long-acting bronchodilators are the main drugs for the treatment of asthma. The current Chinese medicine is only as an auxiliary drug, and should not be applied alone to treat asthma. 4, long-term inhaled glucocorticosteroids for asthma dose is safe, generally only 500 micrograms per day or less (only equivalent to one-tenth of a piece of 5 mg prednisone), and rarely absorbed into the bloodstream, generally does not cause osteoporosis in the elderly, diabetes and other side effects.
