An epidemic has made disinfectant an indispensable weapon for ordinary people to fight the new crown virus. However, as the whole society pays special attention to environmental disinfection and air disinfection, disinfectants may become a factor in inducing recurrence of asthma patients. So, what should asthma patients pay attention to when using disinfectants? As the season changes in late winter and early spring, how can we prepare for allergy prevention?
Disinfectants may induce asthma
The risk factors of asthma include host factors (genetic factors) and environmental factors. Most asthma patients are allergic, and they have hypersensitivity to certain allergens in the environment, sometimes manifested as an acute attack of asthma.
Commonly used disinfectant products can be divided into 9 types according to their ingredients: chlorine-containing disinfectants, peroxide disinfectants, aldehyde disinfectants, alcohol disinfectants, iodine-containing disinfectants, phenolic disinfectants, ethylene oxide, Biguanide disinfectants and quaternary ammonium salt disinfectants. Most of them have a pungent odor, especially when the concentration is too high and the spray is too dense, it can stimulate the sensory nerve endings under the bronchial mucosa, reflexively cause vagus nerve excitement and cough, and cause bronchial smooth muscle spasm on the basis of airway hyperresponsiveness , Which triggers wheezing.
Other families like to add fungicides, vinegar, etc. to the humidifier water tank, but they don’t know that these “tips” will also cause certain damage to the respiratory mucosa, leading to diseases such as bronchitis, pneumonia, and asthma. Because chlorine and 84 disinfectant are added to the humidifier, it actually atomizes the components of the disinfectant. As a result, the components of the disinfectant are more easily absorbed by the human respiratory tract, which may cause allergic reactions and even damage Respiratory tract mucosa.
In view of this, it is recommended that asthma patients use disinfectants according to the instructions; they should not spray directly on people; if they are particularly sensitive to certain disinfectants, they can try to switch to other types of disinfectants; once asthma is induced, they must It is necessary to promptly apply quick-acting drugs to relieve asthma symptoms (such as salbutamol aerosol, etc.), and get out of the inducing environment as soon as possible.
Home care 4 attention
Asthma is still a chronic respiratory disease that cannot be cured. At present, when the winter and spring are changing seasons, the temperature changes greatly, so it is also the peak period of asthma recurrence. Only effective prevention, standardized treatment, and strengthened management can control and reduce the occurrence of asthma. Home asthma patients to do the following work:
1. keep warm
upper respiratory tract infection is the most common cause of asthma attacks, more obvious when the season or climate changing. Spring is the season for the high incidence of influenza. Asthma patients should be reduced to crowded areas. Keep warm. Don’t take off your clothes suddenly when sweating to prevent cold. In addition, mood swings, such as worry, sadness, and excessive excitement, can cause asthma attacks. Patients should pay attention to maintaining a calm mind.
2. away from incentives
at home to look for life in patients with asthma allergens, and make anti-allergic measures. Common allergens include but are not limited to: dust mites, pollen, smoke, gasoline, paint, cold air, fungus, cat hair, dog hair, or some chemical odors (such as plasticine, perfume or decoration materials, etc.) ). Do not use nylon products that can easily cause dust accumulation at home, avoid indoor dust accumulation, ensure indoor cleanliness, and often wash and dry bedding. In addition, the patient should avoid staying in the air-conditioned room for a long time. If it is unavoidable, the air conditioner needs to be cleaned regularly.
3. Healthy Diet
Studies have found that men and women have been people with asthma, stick to a healthy diet is the possibility of “difficult to control” the symptoms reduced by about 60% and 27%, respectively. In this study, a healthy diet refers to a large amount of fruits, vegetables, and whole grains; an unhealthy diet refers to a large amount of meat, and a high-salt and high-sugar diet. Because fruits and vegetables are rich in antioxidant nutrients, such as β-carotene, vitamin C, E and trace element selenium, these antioxidant nutrients can scavenge oxygen free radicals, reduce the damage of oxygen free radicals to tissues, and reduce the number of asthma attacks.
4. Rational use of drugs
First of all, don’t abuse antibiotics. Although asthma is an inflammatory disease, it is quite different from bacterial inflammation. The use of antibiotics does not relieve symptoms. Secondly, the medication is mainly inhaled. Compared with other routes of administration, the side effects of inhaled hormones are minimal, and it is relatively safe even if used for a long time, without hormone dependence and related complications. Finally, insist on medication. Asthma is a disease that exists for a long time and recurs easily. Patients should follow the doctor’s advice and insist on using the medicine for a long time, and stop the medicine if the symptoms improve.
