The cough of a child brings endless worries to the parents. The medication for cough is overwhelming, but it is difficult to stop the child’s cough, affecting the rest of the child and parents. The cough is a constant source of worry for parents, as medication, food, physiotherapy, nebulizer and other prescriptions are used one after another, but none of them work. What parents are most concerned about and need to address is how to stop the cough. Why do children cough? A child’s cough is a symptom and a protective reflex that clears out the “garbage” in the respiratory tract by coughing. In that case, coughing is a good thing, so it should not be treated with cough suppression. Even if the cough is protective, if the cough is so intense that it interferes with sleep and eating, it should be treated. Cough treatment also includes expectoration, phlegm reduction, reduction of respiratory mucosal edema, and restoration of endotracheal membrane cilia. Therefore, cough treatment is not simply a matter of taking cough suppressants. First of all, the primary factor of the cough should be analyzed. Only when treatment is directed at the cause will you receive good results. If the infection is confined above the cricoid cartilage (above the pharynx), it is an upper respiratory tract infection. If the infection develops below the cricoid cartilage (below the pharynx), it is a lower respiratory tract infection, which is an infection of the trachea, bronchi, capillary bronchi, alveoli and interstitial lung. If we use the analogy of a big tree, the tree is upside down, above the root is the upper respiratory tract, below the root is the lower respiratory tract. The trunk of the tree is the trachea, the branches are the bronchi, the leaf stalks are the capillary bronchi, the leaves are the alveoli, and the interstitial space is the interstitial lung. The entire respiratory tract can be attacked by various foreign factors and pathological changes, these foreign factors, not simply viruses, bacteria, but also can be a variety of microorganisms, but also a variety of physical and chemical factors, environmental factors, etc., or due to viruses, bacteria and various factors that cause the mucosa of the respiratory tract lesions, can not be improved with the demise of viruses, bacteria and various microorganisms, resulting in the respiratory mucosa itself The damage to the function of the respiratory mucosa leads to the formation of a cough that does not heal for a long time. Therefore, this is the reason why it is difficult to treat cough even with the use of very high grade antibacterial agents. Only then can the cough be cured. Diseases that cause coughs According to the anatomical parts of the respiratory tract, from top to bottom: frontal sinusitis, sinusitis, rhinitis, pharyngitis, laryngitis, tracheitis, bronchitis, capillary bronchitis, pneumonia. According to the spectrum of diseases: whooping cough, pertussis syndrome, cold, flu, upper sensation, allergic cough, bronchial asthma, cardiac cough, and also according to the type of cough: peripheral cough, central cough, according to the theory of Chinese medicine can be divided into: damp-heat cough, cold and asthmatic cough, fever cough, wind cough, etc. To treat these diseases, cough treatment is a complementary treatment, and the weight of cough treatment should not be heavily placed on cough suppressants. Even if the cough is caused by bronchitis or pneumonia, it may not always have an active infection. For coughs that persist for a long time, do not use antimicrobials for a long time, and there is no need to Long-term use of antiviral drugs. There is no bacterial, viral infection, but also long-term use of antimicrobials can only increase the side effects of the drug, a decrease in white blood cells, dysbiosis, impaired gastric function, and a decrease in appetite in children, which is less beneficial and more undesirable. At this time of treatment, we should focus on the protection, repair and functional recovery of the respiratory mucosa, such as taking vitamin AD pills, which is conducive to the repair of the lining, drinking more water, suitable humidity of indoor air, which improves the function of cilia movement, thins the sputum and facilitates the discharge, fresh air, reduces indoor dust, reduces the stimulation of physical and chemical factors, and helps the recovery of the respiratory lining function.
