We often have children who come to the clinic because of slow growth and development, and we find that many of them have a history of recurrent respiratory tract infections and frequent antibiotic treatment; there are also parents who know some medical knowledge or are introduced by friends and acquaintances who bring their children to the clinic for recurrent infections. The following, based on their own experience and review of literature, to introduce parents to some of the disease Chinese and Western medical understanding and diagnosis and treatment knowledge. I. Conceptual understanding Recurrent respiratory infections (RRI) in children refers to recurrent upper respiratory infections more than 5~7 times or lower respiratory infections more than 2~3 times in a year.RRI is a common and frequent disease in children, with an incidence rate of about 20%, and the incidence rate among children aged 0~6 years is 9.0%~13.2%, with a rising trend. Because of the long course of the disease, affecting the growth and development of children, and the lack of special treatment methods, it is important to actively prevent and treat the disease for its causes and triggers, and modern medical understanding and related tests: 1. 2. Evaluation of airway hypersensitivity or allergy status, allergen testing can be done, and if caused by allergy, allergen intervention and desensitization treatment can be performed. 3.Evaluation of airway developmental malformation (chest CT + airway reconstruction): If there is a possibility of airway developmental malformation, further bronchoscopy is needed to determine the treatment plan. 4.Immunodeficiency (immune function test). If there is an innate immune deficiency, further genetic testing and special treatment is required. Medication, including drugs to increase immunity and allopathic drugs, of which drugs to increase immunity need to be taken for 1~3 months. 5. Inadequate lung function: lung function evaluation (for children over 5 years old). The above items need to be provided at the discretion of a professional doctor after taking a medical history and conducting a physical examination of the child. Traditional Chinese medicine understanding and management Children are born with delicate internal organs, not yet full of form and gas, thin skin, not close to the fence, not solid outside the guard, coupled with heat and cold can not self-regulate, easy to feel external evil. Some children lose nourishment later in life, resulting in the lung surface more deficient, the external evil from the skin, mouth and nose and people, invading the lung guard, the surface guard is not and, therefore, easy to catch a cold. According to the physiological characteristics and clinical manifestations of children, the pathogenesis of children is lung spleen qi deficiency and lack of consolidation of the surface of the body. The timing of TCM physical conditioning is usually chosen during the remission period of the child’s condition, and the dosage form is mostly used for chronic conditioning, and the course of treatment is usually 2~3 months. The formula takes Nourishing Lung Soup as the basic formula, combined with the child’s condition and the characteristics of the symptoms, and uses Yu Ping Feng San, Er Chen Tang, Gui Zhi Tang and Ginseng Ling Bai Zhu San to combine the drugs for tonifying the lung and consolidating the surface and strengthening the spleen and resolving phlegm into one, so as to generate qi and blood and enrich the vital energy, thus improving the overall effect of the formula. To harmonize Ying and Wei, Gui Zhi Tang is preferred. For children with recurrent colds accompanied by spontaneous sweating and night sweating, and cold extremities from sweating, Gui Zhi Tang is often used for treatment. Reconciling the spleen and stomach restores the function of the internal organs. The deficiency of both lungs and spleen is an intrinsic factor in the pathogenesis of the disease and is also the final outcome of its development. If the spleen is strong and healthy, all the five viscera and six bowels will be nourished, and each will perform its own function, so that evil will not offend. The formula is based on Six Junzi Tang and Ginseng and Atractylodes with added flavor to pacify the spleen and earth. The formula uses Ginseng, Poria, Atractylodes, Xiang Lian, fried lentils, fried yam, black beans, fried lentils, etc., to cultivate the earth and produce gold to eliminate the source of phlegm. When the phlegm is clear and the lung qi is smooth, all the symptoms will be calmed. In clinical practice, it is found that treatment with poultices has significant advantages in relieving the frequency of recurrent respiratory tract infections, alleviating the symptoms of attacks and shortening the duration of the disease, and improving the physical condition of the children, correcting their deviations and restoring their pacification.
