Cough is a common clinical symptom in children. Parents often report that their child has had a cough for more than a month, mostly at night or in the early morning, with paroxysmal onset, without fever or shortness of breath, and with no significant abnormalities on chest x-ray or blood tests. In the past, these children were often diagnosed as “cold” or “bronchitis”. In recent years, with the continuous development of medical science, scholars at home and abroad have discovered that these children may suffer from allergic cough, clinically known as cough variant asthma, which is an insidious form of asthma with cough as the main clinical manifestation. Currently, there are data showing that the number of patients with allergic cough in cities with significant industrialization and developed coastal areas is increasing year by year, indicating that the environment has a very obvious influence on allergic cough. Secondly, the seasonal climate also has a great influence on allergic cough. When spring is in full bloom and willows are flying, it is also a good season for allergic cough. If an allergic cough is mismanaged, a significant proportion of children may be transformed into typical asthma, which is troubling to many parents. How can parents correctly understand allergic cough? How to prevent and treat allergic cough in spring? 1. What is allergic cough? Allergic cough is a type of chronic cough in children and is characterized by the following clinical features: 1. 2. No clinical manifestations of infection, or ineffective after longer antibiotic treatment. 3.Treatment with bronchodilators (e.g. aminophylline, procaterol, etc.) can result in significant relief of cough symptoms. 4.There is a personal history of allergy (such as infant eczema, urticaria, allergy to certain foods) and family history of allergy (parents and relatives with allergic rhinitis, etc.). The cough symptoms can be relieved with bronchodilators (aminophylline, etc.). If a child’s cough has the above characteristics, it can be diagnosed as an allergic cough. II. What to do after a child has an allergic cough It is important to treat children early after they have an allergic cough. Coughing is a defense function of the human body. Secretions and inflammatory substances in the airways can be expelled from the body with coughing. However, severe and prolonged coughing not only affects your child’s school and life, but can also lead to other illnesses. Allergic coughs usually last for more than 4 weeks, and children and their parents are often troubled by prolonged coughs that do not improve over time. Since the cough usually comes on at night or early in the morning and usually does not cough or rarely cough during the day, parents tend to think that their child has a cold or flu and do not pay much attention to it, or simply give their child antibiotics and cough medicine. Since the child has an allergic cough, antibiotics are no longer effective at this time, and over time, the child can develop into a typical bronchial asthma. Therefore, it is important to have a clear diagnosis and standardized treatment in time. The combination of Chinese and Western medicine is effective, with Western medicine being used for control during the acute phase and Chinese and Western medicine being used for treatment during the remission phase. Western medicine treatment advocates nebulized inhalation of glucocorticoids and β2 agonists, oral leukotriene receptor antagonists, antihistamines, etc. for combined treatment. Chinese medicine treatment is to promote the lung to stop cough and strengthen the spleen to resolve phlegm. In addition, the external treatment methods of Chinese medicine, such as massage and chiropractic, Chinese medicine compress, etc., also have a good effect on cough and phlegm. Chiropractic manipulation is gentle, painless and easy for children to accept. Chinese medicine acupressure is a unique external treatment method in Chinese medicine, which integrates the knowledge of many disciplines such as Chinese medicine, time medicine and immunology. According to the theory of “treating winter diseases in summer and preventing summer diseases in winter” and “treating internal diseases externally”, acupuncture point compressing is carried out in the third nine days of the lunar calendar and the third volcano, using Chinese herbs such as white mustard seeds, pseudostellaria, gansui, etc., and compressing the corresponding acupuncture points such as dazhi, lung yu, ankylosis, etc., through transdermal absorption and acupuncture point conduction. This can help adjust the immune function of the body through transdermal absorption and acupuncture point conduction, thus having a better preventive and curative effect on chronic cough, allergic rhinitis, bronchial asthma, etc. The cause of pediatric allergic cough is complex and is influenced by both genetic and environmental factors, of which allergies are closely related to the disease, while environmental factors are often triggering factors, such as contact with or inhalation of pollen, dust mites, fur, cold air, or consumption of seafood and other foods. It is important to avoid allergens and parents of children with allergic cough should pay attention to: 1. When the seasons change and the temperature changes suddenly, parents should pay attention to increasing and decreasing the child’s clothes in time to avoid catching cold and flu. 2. 2. Avoid foods that cause allergic symptoms, such as seafood and cold drinks. 3. Don’t keep pets at home, don’t lay carpets, don’t keep flowers in the bedroom, and avoid contact with pollen, dust mites, oil fumes, paint, etc. 4.Don’t let children sleep with long fluffy toys. 5.In spring, when the willows are flying and flowers are in full bloom, you should reduce the number of activities outside or give your child a mask to wear when you go out. 6.If you have allergic rhinitis, rhinitis, sneezing, runny nose, or frequent coughing episodes every spring, you can take oral anti-allergy medications such as paracetamol, ketoprofen, loratadine, cetirizine, etc. in advance.
