I. The concept of pediatric recurrent respiratory infections Recurrent respiratory infections are common and frequent in pediatrics, and the children are called recurrent children. According to statistics, its incidence is between 9.0% and 13.3%, accounting for 20%-30% of pediatric respiratory infections. Respiratory tract infections include upper respiratory tract (nose, sinuses, pharynx, eustachian tube, epiglottis and larynx) infections, referred to as “upper respiratory tract” and lower respiratory tract (trachea, bronchi, capillary bronchi, respiratory capillary bronchi, alveolar tube and alveoli) infections, referred to as “lower respiratory tract”.) The diagnosis of recurrent respiratory tract infections in children was formulated in 1987 at the National Pediatric Academic Conference, refer to the following table: Yang Weiwei, Department of Pediatrics, Jining Hospital Age (years) Number of occurrences of upper sensation/year Number of occurrences of lower sensation/year: 0 — 2 7 3, 3 — 5 6 2, 5 — 12 5 2 Note: The time interval between the first and second illness is at least 7 days. Second, the factors that cause recurrent respiratory infections in children 1, their own lack of positive energy: insufficient endowment (mother sick during pregnancy, nutritional imbalance, etc., affecting the normal growth and development of the fetus), improper feeding resulting in nutritional deficiencies or the impact of other diseases, improper use of drugs to deplete the positive energy. 2, life and living care is not appropriate: some parents love their children too much, and they are accommodating and indulgent children picky food, partial food, snacking, eating fat, sweet, raw and cold, which damage the spleen and stomach; or dress too warm, “will raise too warm”, so that the children’s Yang Qi more hyperactive, depleting Yin liquid. The basic pathogenesis of recurrent respiratory tract infections in children is considered by Chinese medicine to be the deficiency of lung and spleen qi, the lack of solidity outside the body, and the stagnation of the stomach and intestines. As most children nowadays are only children with superior living conditions, their parents spoil them with indulgence and indulge them with fatty, sweet and thick food, or indulge their preferences, such as partial food and food cravings, resulting in damage to the spleen and stomach, stagnation of food, internal stagnation in the middle and stomach, accumulation without transformation, accumulation of heat for a long time, and internal heat induces external sensation. And there are children with a weak spleen and stomach, or after the disease is out of order, feeding and conditioning inappropriate, transport and transformation is weak, stagnant diet is not eliminated, spleen deficiency and stagnation as a result of each other, forming a vicious circle, day after day lung and spleen weakness, the body’s resistance to decline, more susceptible to external sensations. Fourth, preventive measures 1, life and living care, reasonable regulation of diet ancient people say: “If you want children to be safe, often suffer three hunger and cold”, “milk expensive sometimes, food expensive”, therefore, to children according to the temperature of cold and warm at any time to increase or decrease clothing; strengthen the diet of children To strengthen the diet of children, correct bad eating habits, eat more vegetables and fruits, meat and vegetables with reasonable mix, less snacks, should not overeat, food should be light and nutritious. 2, Chinese medicine prevention years of clinical experience has confirmed the close relationship between endogenous stagnation and the onset of recurrent respiratory tract infections in children. Clinical observation shows that recurrent respiratory infections induced by stagnation in the spleen and stomach of children can account for 50% to 60% of the total incidence. The method of eliminating food stagnation and resolving stagnation is divided into two types of treatment according to the different physical conditions and symptoms of the children, namely, food stagnation and heat and spleen deficiency and stagnation. It can improve the child’s physical condition, significantly improve the child’s resistance and reduce the attacks of recurrent respiratory tract infections, which reflects the essence of “treating the disease before it happens” and “treating the disease at the root” of Chinese medicine. “It can significantly improve the number, duration, type of disease, symptoms and signs of the child.
