Recurrent respiratory tract infections are those with a certain number of respiratory tract infections per year or more, depending on the age group, and excluding those associated with lung, tracheal and cardiac congenital malformations, gastroesophageal reflux and other diseases. The main clinical features are cold, milk moth, cough, pneumonia and wheezing in a period of repeated infections for a long time. I. Etiology and pathogenesis The recurrent respiratory tract infections in children are mostly due to the deficiency of positive energy and lack of solidity outside the body, resulting in repeated exposure to external evil, evil toxins for a long time, slightly healed and made, repeatedly. Insufficient endowment, weak constitution If the parents are weak and sickly or suffer from various diseases during pregnancy, or the child is born prematurely, multiple births, weak fetus, after birth, the muscles and bones are tender and timid, the couples are lax, and they are not resistant to the invasion of the incorrect gas in nature, and they are sick when they feel it. Improper feeding, inappropriate care Manual feeding or premature weaning due to insufficient breast milk, or partial feeding, anorexia, malnutrition, the spleen and stomach transport power is weak, the intake of dietary essence is insufficient, the function of the internal organs is not healthy, the spleen and lung Qi deficiency, vulnerable to external attacks. The wind and sun are rarely seen, and the wind and cold are not tolerated. Outdoor activities are too little, sunlight is not enough, the skin is soft, the guard is not solid, the adaptability to the cold is weak, like the grass and trees in the shade, the flowers in the greenhouse, soft and brittle and not resistant to wind and cold. Once the shape of cold drinking cold, cold immediately occurred, or others cold, a dye that disease. After the disease and easy to occur after the transmission. Inappropriate use of drugs, damage to vital energy After the cold, over-serving the agent of relieving the table, damage to the Wei Yang, so that the table Wei Qi deficiency, Ying and Wei, Ying Yin can not keep and sweat, Wei Yang can not be outside the easy to feel. Inappropriate use of drugs depletes the child’s vital energy, causing a decrease in resistance and repeated exposure to evil. After the attack of external evil, due to the weakness of the right qi, evil toxins often can not be cleared, stay in the lane, once the cold or fatigue, the new sense of susceptibility, the retention of evil within the hair; or no new sense, the old disease rekindled, the evidence again. In short, children’s internal organs are delicate, the skin is weak, the fence is loose, the yin and yang two qi are relatively young and weak, and the children with repeated sensations are more deficient in the lungs, spleen and kidneys, the external function is weak, the resistance to external evil is poor; coupled with the cold and warmth cannot be self-regulated, once biased, the six evil spirits, whether from the skin and hair into, or from the mouth and nose, are affected by the lungs. The changes in the growth and decline of positive and negative causes the occurrence of recurrent respiratory tract infections in children. Clinical diagnosis Diagnostic points (1) 0~2 years old children, more than 10 respiratory infections per year, including more than 3 lower respiratory infections; 3~5 years old children, more than 8 respiratory infections per year, including more than 2 lower respiratory infections; 6~12 years old children, more than 7 respiratory infections per year, including more than 2 lower respiratory infections. (2) The second upper respiratory tract infection should be at least 7 days apart from the first one. (3) If the number of upper respiratory tract infections is insufficient, the number of, lower respiratory tract infections can be added; the opposite is not true. Need to be observed for 1 year. Identification and treatment Identifying ideas The identification of this disease focuses on the clear understanding of the changes of the evil and the positive. During the period of infection, the main focus is on the actuality of evil; during the extension period, the main focus is on the deficiency of evil; during the recovery period, the main focus is on the deficiency of evil. At the beginning, there are mostly external symptoms, so we should identify the difference between wind-cold, wind-heat, external cold and internal heat, the difference between accumulation of phlegm and phlegm, and the pathological mechanism of the original deficiency and the actual symptoms. In the recovery period, when the evil is temporarily winning and the evil is temporarily receding, the key is no longer the evil but the deficiency of the lungs, spleen and kidneys, which is the main deficiency of the lungs, spleen and kidneys. The treatment method In the respiratory tract infection attack period, should be treated according to different diseases, while paying due attention to the physical characteristics of the child is deficient. During the extension period, the main focus should be on supporting the righteousness and eliminating the evil. In the recovery period, it is important to consolidate the root, either by replenishing the qi and fixing the surface, or by transporting the spleen and the camp, or by tonifying the kidneys and strengthening the bones. This section, the recovery period treatment is the main, at this time to seize the opportunity to supplement, so that “ positive energy within, evil can not dry ” to achieve the effect of reducing the reduction of attacks. Fourth, prevention and conditioning prevention (1) pay attention to environmental and personal hygiene, indoor air circulation, frequent outdoor activities, change clothes at any time, gradually adapt to climate change, avoid too cold and too hot. (2) Develop good living habits, ensure sufficient sleep and intake of rich nutrients. (3) Do not go to public places during the flu epidemic. When there are cold patients at home, use vinegar to fumigate the room: use 2~5ml of vinegar per cubic meter of space, add 1~2 times of water, put it in a container and heat it until it is all gassed. Use it once a day for 3~5 days. (4) Actively prevent and treat various chronic diseases, such as vitamin D deficiency rickets, malnutrition, anemia, etc. (5) Timely preventive vaccination of various vaccines or oral preventive sugar pills (such as polio sugar pills, etc.) to enhance the body’s ability to resist disease. (6) Chinese herbal medicine Astragalus 6 to 9 g daily for 2 to 3 months. (1) The appetite of children with recurrent respiratory tract infections is mostly reduced, so a small number of meals can be given with an easily digestible and highly nutritious diet. (2) Children with fever often sweat after their body temperature drops, so they should be replaced with dry and warm clothes in time and bathed regularly. (3) Keep the respiratory tract open and remove nasal secretions frequently. Maintain a proper body position and do not put pressure on the airway. (4) For those who cough and sputum is not easy to get out, parents should be frequently instructed to pat the back of the child; when the sputum is too sticky, the humidity in the room should be increased to 60% to 65% and sufficient water should be supplied; inhalation of warm and moist gas can dilute the sputum to facilitate its discharge. (5) Gargle with silver flower licorice water or physiological saline 2 to 3 times a day until the condition is basically stable.
