Pediatric cough is clinically common in children, causing parents to worry about it and always trying to stop it as soon as possible. There are currently many misconceptions in the understanding and use of medication, which are summarized as follows: 1. Correctly distinguish whether the cough is physiological or pathological. In some cases, normal children may also exhibit occasional coughs and should not be blindly assumed to be sick. A physiological cough is usually a physiological protective measure to eliminate foreign bodies from the respiratory tract. Physiologic coughing is usually beneficial to the body. (1) Foreign bodies entering the respiratory tract (e.g., choking caused by particles of rice, water, medicine, etc.) are expelled through coughing. (2) Volatile gases and harmful air such as gasoline, dust, etc. enter the respiratory tract. (3) When there is discomfort in the respiratory tract, it is usually intentional to make several coughing movements with moderate force, which can keep the respiratory tract open. 2.You can’t see the cough to stop the cough. Children’s internal organs are delicate, so external sensations and internal injuries can easily injure the lungs and cause a cough. The external sensation of cold, heat, dryness and other surface evils invade the lungs, causing the lung qi to rebel; the internal food stagnation, spleen trapped in the production of dampness and phlegm, phlegm and dampness accumulate, and the lung qi loses its propagation; the weakness of the body, prolonged coughing and injury to the fluid, the inflammation of the deficiency fire, burning the lung yin, and the kidney does not receive the qi. The overall pathogenesis of the disease is a loss of lung circulation and purification. Treatment should be based on declaring and purifying the lung qi. Some parents think that a cough should be treated with cough suppressants as soon as the child coughs. Children are generally not suitable for taking cough suppressants alone, especially when they have a cough with phlegm. Most common cough suppressants contain strong central cough suppressant ingredients, such as codeine and forcodine, which act directly on the cough center and have a strong cough suppressant effect, and their use can have an immediate effect on the cough, but may lead to a greater risk of disease. Because the respiratory system of children is still immature, their cough reflex is poor and sputum is not easily discharged. If you take strong cough medicine when you cough, a large amount of phlegm will accumulate in the trachea and bronchi, which not only affects the respiratory function, but also may form deep lesions and aggravate the disease. 3. Blindly apply proprietary Chinese medicines. There is no special solution for cough in Western medicine, and the current treatment is mainly symptomatic treatment to stop coughing and reduce phlegm. Chinese medicine has obvious advantages, and many proprietary Chinese medicines have sprung up in hospitals and pharmacies to facilitate their application, giving treatment to children while there are great misconceptions about their application. Chinese medicine is a dialectical medicine, which focuses on the diagnosis and treatment. The application of proprietary Chinese medicines should also be guided by this principle and used correctly. As mentioned above, pediatric cough can be caused by a variety of factors, including external and internal injuries, and should be applied in combination with the disease mechanism. Currently, most of the Chinese patent medicines on the market are mainly for clearing heat and resolving phlegm, while some of them also nourish yin or benefit qi and strengthen the spleen. Therefore, we should first distinguish between external sensations and internal injuries in their application, and should not blindly clear heat and resolve phlegm or apply Chinese patent medicines with tonic effects at will. In addition, the cough should be applied in stages. In the early stage, the cough is mostly wind-heat, so the main focus should be on clearing heat and resolving phlegm, while in the late stage, the disease is often characterized by yin deficiency and lung heat or lung spleen qi deficiency. In this regard, parents and Western doctors without formal training in Chinese medicine are prone to errors, which are often encountered in the course of clinical treatment and should be taken as a warning. 4. Blindly using antibiotics. Many parents think that a pediatric cough is an inflammation of the respiratory tract, so anti-inflammatory drugs must be used when their child coughs, which can have many adverse effects on the child. Pediatric cough is not only caused by inflammatory stimulation after a respiratory infection, but allergies, smoke and dust, and foreign body stimulation can also cause a pediatric cough. While respiratory tract infections pathogenic viruses are common, children are suitable for the application of antibiotics such as penicillin, cephalosporins, macrolides are not therapeutic and taking them is not beneficial for the treatment of cough, but also often produces toxic side effects in the gastrointestinal tract and kidneys. Therefore, it is important not to abuse antibiotics when children have coughs in order to prevent adverse effects on their health. It is better to consult your doctor when applying them. 5. Over-supplementation. Pediatric cough, during the course of illness, is often accompanied by a loss of appetite and possibly a little weight loss. At present, most urban children are only children, and when a child is sick, his grandmother and grandma are all anxious, and in individual cases, as long as the child likes to eat, no matter what, large fish and meat, seafood and abalone are served together. Do not know that the children themselves spleen and stomach weak, especially when sick, one-sided emphasis on eating some highly nutritious tonic food, injury to the child’s delicate gastrointestinal, resulting in gastrointestinal can not be properly digested, absorption, so that appetite is more in a low state, phlegm and damp, stagnation, aggravating the disease. For this reason, bear in mind that “to get a child safe, three points of hunger and cold”, in the case of sickness to diet should pay more attention to moderation.
