Long sighing in children is a very common clinical symptom and is often thought by parents to be a sign of “myocarditis” and is often treated by most doctors as “myocarditis” for a series of tests, but after the tests are done, it is not enough for the diagnosis of myocarditis or not at all. The doctor may prescribe some drugs to nourish the heart muscle, and the child often has no effect after a period of application. In fact, a long sigh is not necessarily myocarditis. In clinical practice, only a very small number of people meet the diagnosis of myocarditis, and most of them are caused by physiological disorders. The Chinese medicine has a more appropriate understanding of this, Chinese medicine will be a long sigh is called “good too breath”, too breath is the exhale based deep breathing, and sigh synonymous. Normal people also have intermittent deep breathing, if frequent sighing, it is a pathological state, Chinese medicine is called “good tai breath”. Good Tai Breath is a common clinical symptom in pediatrics, mainly manifested as children often feel short of breath and sigh frequently to relieve chest tightness, which can be seen in many diseases. Chinese medicine has identified the causes of this symptom and divided the symptoms into liver and gallbladder heat, heart qi deficiency, phlegm blocking qi and other types of evidence for treatment, and achieved better results. 1, liver and gallbladder depression heat Children are weak, psychologically unsound, emotionally unstable, lack of external stimulus stress capacity, prone to Qi disorders, dysfunction of the internal organs, that is, internal injury of emotion and will. More often than not, children are obstinate and easily provoked, and if they do not want to, they often cry and fuss, or they are angry and do not speak. Zhu Danxi said: “Children are easily angered, and liver disease is the most common”, and if they are not relieved of their anger, their liver and gallbladder will be injured. Spiritual pivot – bloating theory: “bile bloating, pain under the duress, bitter in the mouth, good tai breath”. Most of the children seen in clinical practice have mental and emotional triggers before the onset of the disease. The treatment should be patient to understand the cause of the child’s long sighing symptoms, and supplemented with medication after appropriate psychological guidance. Commonly used formula such as gentian diarrhea of the liver soup with addition and subtraction, if the mouth is bitter and heavy, the liver and gallbladder is depressed heat, transverse rebellion offending the stomach, add bamboo rhizome, Huang Lian; if the chest is distended and painful, add neem, green peel, heliotrope. For example, a child, female, 8 years old, was good at breathing for two weeks. It is accompanied by chest tightness, dysmenorrhea, bitterness and irritability, and a red tongue with yellow fur. She felt that her teacher had blamed her for the conflict with her classmates, but she was criticized by her teacher. We gave psychological guidance and prescribed a prescription to clear the liver and Qi, clear the heat from the gallbladder: Gentiana 10g, Scutellaria 10g, Radix Bupleurum 10g, Radix Bupleurum 10g, Green Peel 6g, Plantago ovata 10g, Neem 10g, Bamboo Roo 10g, Thicket 10g, Chen Pi 10g, White Peony 6g, Licorice 4g. The symptoms disappeared after three doses of oral administration. 2.Insufficient heart qi The child is weak and has a history of repeated respiratory tract infections, repeatedly feels external evil and damages the heart arteries, resulting in insufficient heart qi and difficulty in stimulating the blood vessels, poor blood flow and unfavorable qi flow, resulting in tai hui chest tightness, shortness of breath and palpitations, weakness and sweating, little movement and tiredness, and lack of color. The treatment is to nourish the heart with qi, commonly used formula such as Shengwasan, Bao Yuan Tang plus or minus. Qi deficiency and sweating plus floating wheat, raw oyster; palpitations and palpitations plus roasted licorice, raw keel; chest pain plus Dan Shen, Yu Jin, red peony. For example, a boy, 12 years old, has been sighing for 2 months. 2 months ago, he had a cold, and more than 10 days later, he had chest tightness and long sighing, and was diagnosed as “myocarditis”, and the treatment was ineffective. In the past 7 days, he had sneezing, breathlessness, chest tightness, palpitations, sweating, and tiredness with little movement. On physical examination, he had a pale white face and a thin white tongue. The prescription is to supplement heart energy: Radix et Rhizoma Ginseng 10g, Radix Astragali 10g, Radix Paeoniae Alba 10g, Radix Medlar 10g, Pericarpium Citri Reticulatae 10g, Fructus Schisandrae 6g, Radix et Rhizoma Longan 10g, Radix oyster 12g, Radix et Rhizoma Glycyrrhiza Uralensis 6g, decocted in water. The child was also instructed to take more rest and avoid strenuous activities. After three doses, the symptoms were relieved and disappeared with six more doses. 3.Phlegm obstructs the qi mechanism Most often seen in children who eat a large amount of food, prefer meat and sweets, and are obese. The spleen of children is often inadequate, such as poor diet and diet preference, the spleen is not healthy, phlegm is generated, “the spleen is the source of phlegm, the lung is the storage of phlegm”, phlegm blocking the qi, so the breath is made, chest tightness and shortness of breath, or cough and phlegm and other symptoms. The treatment is to strengthen the spleen, resolve phlegm, move the qi and lower the rebellion, commonly used formula such as Han Xia Hou Pu Tang plus or minus. If there is a lot of phlegm, add zhebeimu, guavas, dongguaren; chest tightness, add allium, mulberry skin; constipation, rhubarb, lycopodium, heliotrope; heat, add scutellaria, Huanglian. For example, a 7-year-old girl with a month-long sigh, accompanied by cough and sputum for half a month. The child loves meat, eats a lot, is obese, and has constipated stools. One month ago, she developed a good sigh, which was not taken seriously and was not seen. Half a month ago, he developed cough and sputum due to cold, with yellow and sticky sputum, and his tongue and lips were red and his tongue coating was yellow and thick. The prescription was to resolve phlegm and heat, clear heat, regulate Qi and subdue rebellion: Chen Pi 10 grams, Radix Panax notoginseng 6 grams, Poria 6 grams, Scutellaria baicalensis 10 grams, Houpu 10 grams, Huang Lian 6 grams, Guadua 20 grams, Zhe Bei Mu 10 grams, Fried Lycopodium 10 grams, Fried Citrus aurantium 6 grams, Mulberry Peel 10 grams. The child was also instructed to diet, eat lightly, moderate the amount of food and meat, and increase exercise in moderation. After taking three doses, the sighing cough was relieved and the stools became soft and clear, and the symptoms disappeared with five more doses. In conclusion, parents of children with long sighs and certain doctors who are not sufficiently aware of long sighs need to have a more comprehensive understanding of this manifestation, and after doing relevant tests to exclude myocarditis, Chinese medicine identification and herbal treatment can be carried out to avoid unnecessary drug treatment.
