 How can asthma patients protect themselves during the season change?


The asthma caused by pollen has distinct seasonal and regional characteristics, and each patient may be allergic to certain pollen, which will lead to asthma attack in a specific season and place. The pollen related to asthma can be divided into three categories: the first is large plant pollen, such as maple, elm, cypress, pine, willow, mulberry, Sophora tree, etc., which often causes allergic asthma in spring; the second is wood plant pollen, such as Dogtail grass, rye, etc., which often causes allergic asthma in late summer and early autumn; the third is xiucao pollen, such as ragweed, Hedgerow grass, which often causes allergic asthma in autumn Asthma.

2. Nine conditions easy to induce asthma

There are also some factors inducing asthma, regardless of season and region, in our daily life for a long time. They are not only from the external environment of a variety of stimuli, disease infection, but also individual activities, diet medication and other factors. The most effective strategy to prevent asthma is to correctly identify the sensitive population and risk factors.

2. Outdoor pollen. In addition, indoor and outdoor fungi are also common inducements.

3. Indoor air pollution. For example, cigarette smoke, coal-fired stove smoke, burning wood grass, cooking oil fumes, household sprays and pungent odor cosmetics, including perfume, hair spray, talcum powder, interior decoration materials, paint smell, insecticide aerosol, mosquito repellent incense, and Lai Su Shui.

4. Viral upper respiratory tract infection. For example, upper respiratory tract infection caused by respiratory syncytial virus, rhinovirus and influenza virus can induce and aggravate asthma.

5. Vigorous exercise and hyperventilation. The occurrence of exercise-induced asthma is related to the type of exercise, the tension of exercise and the surrounding climate. For example, running, mountaineering, walking and playing basketball in cold and dry seasons are easy to induce asthma, while swimming, boating, cycling and other sports in warm and humid summer are less likely to induce asthma; walking, Taijiquan and other minor sports are less likely to cause asthma, while vigorous exercise is easy to cause asthma attack.

6. Climate change and air pollution. Climate change such as cold air, high humidity, low air pressure, thunderstorm and other weather changes can easily induce asthma. Sulfur dioxide, particulate compounds, photochemical smog (ozone and nitric oxide) in air pollution are also incentives.

8. Drugs. For example, aspirin, aspirin compound preparation and other non steroidal anti-inflammatory drugs (commonly used such as APC, kesensin, quick acting cold capsule, Qutong tablets, indomethacin, ibuprofen, fenbide, etc.); u03b2 - receptor blockers (such as propranolol, aminopropranolol, Betaloc, etc.).

9. Extreme mood swings. Such as crying, laughing, anger, fear and panic are easy to induce asthma.

It should be specially reminded that the chlorine containing disinfectant widely used during the epidemic has an irritant odor. When the concentration is too high and the spray is too dense, it is easy to stimulate the skin and mucous membrane or induce cough and asthma.

3. The first choice is inhaled hormone

The basic treatment principle of asthma is to avoid contact with allergens and other inducements as much as possible, adhere to the regular inhalation of glucocorticoids, and inhale u03b2 2 receptor agonists when necessary, which is a general requirement. Specific to each asthma patient, in different circumstances, the treatment plan will be different, that is, the asthma treatment plan always emphasizes individualization.

The essence of asthma is chronic airway inflammation. This kind of inflammation is not equal to the inflammation caused by bacteria or virus infection as we usually talk about. Antibiotic treatment is ineffective. At present, the best medicine to treat this kind of inflammation is glucocorticoid. Compared with oral administration and intravenous administration of corticosteroids, inhaled corticosteroids can make the drug reach the local airway better and play an anti-inflammatory role. The drug needed is small in dosage, fast in action, high in safety, good in efficacy and few in side effects. Inhaled corticosteroids are the first choice for the long-term treatment of persistent asthma.

Because airway inflammation is very sensitive to all kinds of stimulation, it is difficult to cure asthma. But after long-term standardized treatment, asthma can be completely controlled, which is to achieve what we call clinical cure. Asthma patients who have achieved clinical cure can work and live like healthy people. For example, the star Beckham suffered from asthma since he was a child, but it obviously did not affect his excellent performance on the court. Therefore, after standardized treatment, asthma patients can also live like ordinary people, and even become professional athletes.

During the epidemic period, asthmatics should check the drug inventory regularly. If the patient is in a stable condition, it is recommended to go to the hospital once to supplement more drugs to reduce the frequency of medical treatment. If the disease continues to worsen and cannot be controlled, timely medical treatment should be carried out on the premise of good protection.

4. Daily living protection is very important

According to the novel coronavirus pneumonia outpatient guidelines issued by the Beijing CDC on May 1st, people can no longer wear masks in the Central Plains on outdoor activities. However, novel coronavirus pneumonia can cause asthma in asthma patients. It is also suggested that the infection of new crown pneumonia will aggravate asthma. Therefore, it is suggested that asthma patients should try to reduce their outgoing and keep wearing masks when they go out.

It is very important for asthma patients to do a good job in daily life. First of all, with the coming of summer, many people like to wear silk fabrics, but it is better for asthmatic patients not to wear silk clothes, because some asthmatic patients are allergic to allergens in silk. Secondly, we should pay attention to whether the attack of asthma is related to eating some heterogenous protein, such as fish, shrimp, crab, eggs and milk. If so, we should avoid eating as much as possible. In addition, we should also observe whether the attack of asthma is related to eating cashew nuts, sesame seeds and peaches. Some food additives, such as the beverage made of tartar yellow and the colorant added to the pastry, such as the nitrite used for bleaching and antisepsis when making candy and pastry, can also induce asthma. Third, use or avoid some drugs that may induce asthma, such as aspirin and aspirin containing compound preparations (APC, kesensin, quick acting cold capsule), Qutong tablets, indomethacin, ibuprofen, fenbide, propranolol, aminopropranolol, Betaloc, etc. If there are patients with gastroesophageal reflux, the following measures should be taken: first, stop drinking alcohol; second, do not eat 2 hours before going to bed, usually a small amount of more than one meal, avoid overfull; third, drink less tea, coffee, cola, avoid spicy food; fourth, raise the head of the bed 15-20cm.
