Respiratory tract infection is a common disease in pediatric patients, and it is normal for it to occur several times a year, but if there are more than 3 pneumonias or frequent respiratory tract infections >6 times a year, it is called recurrent respiratory tract infection, which is clinically associated with loss of appetite, night sweats, weight loss, yellowing, and mental lethargy. Recurrent respiratory tract infections are not an independent disease, but a group of clinical syndromes that occur due to the following factors: (1) the tenderness of the respiratory tract mucosa in children is susceptible to infection; (2) the systemic immune defense function of children is not well developed, i.e., low resistance; (3) many children have underlying diseases, such as allergic asthma, rhinitis and other allergic constitution; (4) related to nutritional status, vitamin and trace element deficiency; (5) (5) Repeated use of antibiotics, resulting in dysbiosis secondary to immune deficiency; (6) Environmental factors such as atmospheric pollution, passive smoking, environmental changes and cross-infection after admission to nursery. Treatment measures: (1) Active search and treatment of the underlying disease, more active search for the cause of recurrent pneumonia children, with special attention to premature birth, bronchopulmonary dysplasia, various types of immunodeficiency diseases, asthma, foreign bodies and severe pneumonia after, timely and clear diagnosis, take effective measures to achieve remission or cure; (2) regular anti-infective treatment to remove the foci suitable for the incubation of bacteria; (3) appropriate application of (3) appropriate application of immunomodulators; (4) correction of malnutrition, vitamin and trace element deficiency, etc. Acupoint injection therapy is a unique therapy guided by the basic theory of TCM to stimulate the therapeutic effects of meridians and acupoints, combined with the pharmacological effects of drugs and injection methods of modern medicine. It plays a superimposed role of combining acupuncture points, needles and drugs. In addition, the effect of immunomodulators on acupuncture points can also act on the body through the nervous system and neurohumoral system, stimulating the body’s ability to resist disease and producing powerful therapeutic effects. Treatment of recurrent respiratory tract infections in children starts with strengthening the child’s own resistance.
