Mycoplasma infection is another pathogenic organism distinguished from bacterial viruses, and most infections in children are characterized by high fever and cough, especially at night. Its clinical manifestations are mainly fever, most infants and young children with high fever, ordinary drugs for bacterial and viral infections are basically ineffective; lung auscultation and radiograph results are often inconsistent, in other words lung auscultation is not different, but the radiograph is the manifestation form of bronchitis pneumonia. Blood tests for mycoplasma infection as well as clinical symptoms of the baby are used to confirm the diagnosis. The treatment of mycoplasma infection in children is as follows: 1, the drug of choice for mycoplasma infection is azithromycin, if the infant is more sensitive to the drug, there is obvious nausea, vomiting or even allergic symptoms, you can change other macrolides such as roxithromycin. 2.The effect of taking 1~2 courses of treatment is not very good, and even the symptoms of bronchitis appear, intravenous azithromycin is needed for treatment. 3.If the cough is prolonged, it may be secondary to an allergic cough, so oral anti-allergy medication such as montelukast sodium is needed, and it can also be treated with budesonide and terbutaline nebulization at the same time. 4. During the fever, the child should wear loose clothing to facilitate perspiration, and at the same time cooperate with physical cooling by wiping the armpits, forehead and groin with a warm towel; if the home temperature allows, you can cooperate with a warm bath for physical cooling. When the body temperature exceeds 38.5℃, it is still necessary to give ibuprofen or acetaminophen to reduce fever. It is important to eat small and frequent meals and not to eat overly greasy food, which can easily aggravate the gastrointestinal tract. Eating more foods rich in vitamin C, such as oranges, kiwis and tomatoes, is beneficial to the recovery of the disease, and foods such as lily of the valley and lotus seed soup and pear stew with Sichuan scallops are also beneficial to the recovery of the child’s cough.
