Analysis of etiology and pathogenesis of diagnosis and treatment ideas
The main cause of children's cough is the feeling of exogenous evil, among which the feeling of wind evil is the main one. The book "Living Young Heart Book Cough" points out: "Cough patients are divided into several types, but they are divided into cold and heat, which are relieved with the syndrome. In junior high school, they were not injured by a cold. " It is pointed out that cough is mostly caused by exogenous factors. In addition, the weakness of lung and spleen is the main internal cause of the disease.
The pathological change of cough is located in the lung, which often involves the spleen. The pathological mechanism is lung failure. The lung is fine and dirty, clear in nature and qi, clear in throat, clear in nose, covered with fur, controlling qi and breathing. Exogenous pathogens enter from the nose, mouth or fur, and the pathogens invade the lungs, and the lungs are unaware of it, and cough occurs due to dereliction of duty. Children's spleen is often deficient, spleen deficiency produces phlegm, which accumulates in the lungs, or chronic cough does not heal, which damages vital qi and can be turned into internal injury and cough.
1. The main reason for feeling external evil is feeling wind evil. Wind pathogen causes disease, the first attack is lung defense, and the pathogen enters the lung, the lung collaterals are blocked, and the lung qi is blocked, leading to cough. Wind is the length of all diseases, and other exogenous pathogens often attack the human body with the wind. If the wind is accompanied by cold evil, wind-cold binds the lungs, and the lung qi loses its propaganda, you will see frequent coughing, severe itching in the pharynx, and white and thin sputum; If wind and heat are mixed, wind and heat invade the lungs, and the lungs lose their benefits, it will cause uncomfortable cough and sticky phlegm.
2. Phlegm heat accumulates in the lungs. Children's lung and spleen are weak, qi is not good for body fluid, and phlegm is easy to breed. If the food is accumulated with internal heat, or the heart and liver are hot, or the exogenous pathogenic heat is lost, the semen becomes phlegm, and the phlegm and heat are combined, which is blocked in the airway and the lung qi is not smooth, resulting in cough with more phlegm, thick and yellow phlegm, which is not easy to cough up.
3. Children with phlegm-dampness accumulating in the lungs are often spleen-deficient, vulnerable to breast-feeding and wind-cold, which makes the spleen lose its health, and water-dampness can't be transformed into body fluid. Shui Gu can't be transformed into subtle body fluid, so it turns into phlegm and hides in the lungs. The lungs are too delicate to apply body fluid, which turns into phlegm and blocks the airway. If the lungs are not healthy and the qi is not smooth, it will cause cough and phlegm, and the phlegm is white and thin.
4. Children with lung-qi deficiency are deficient in congenital endowment and weak in constitution, or cough caused by exogenous factors lasts for a long time, which will lead to lung-qi deficiency, weak temper, poor transport and transformation, insufficient qi, endogenous sputum and accumulation in lung collaterals, resulting in persistent cough, cough weakness and thin phlegm.
5. Children with lung yin deficiency have tender lungs. If the cough is caused by exogenous factors, if it does not heal for a long time, it will fall in love with positive deficiency and evil excess, heat will hurt lung and body fluid, and yin and body fluid will be damaged. Yin deficiency leads to internal heat, which damages lung collaterals, or yin deficiency leads to dryness, resulting in persistent cough, dry cough without phlegm and hoarse voice.
Although there are many reasons for children's cough, its pathogenesis is one, all of which are caused by lung involvement and lung failure. Exogenous cough begins in the lung, and endogenous cough can be caused by lung disease or other diseases involving the lung.
