Diagnosis of mycoplasma pneumonia is based on the following:

(1) Persistent cough, more frequent, no obvious positive signs in the lungs, but X-ray examination has patchy or large shadows, X-ray lesions are obvious, which is the most important feature of the disease.

(2) The white blood cell count is mostly normal or slightly reduced.

(3) The use of penicillin, streptomycin, and sulfonamides is ineffective, but erythromycin can significantly reduce symptoms or shorten the course of the disease.

(4) The titer of serum cold agglutination was increased, more than 1:32, the positive rate was 50%~70%, and the cold agglutinin began to appear at the end of the first week after the onset of the disease, reaching a peak in 3~4 weeks, and disappearing in 2~4 months. Both bacterial (including tuberculosis) and viral infections are negative, so tuberculosis, bacterial, and viral pneumonia can be ruled out.

(5) Isolation of pathogens: mycoplasma is cultured from sputum, nasal and throat swabs of children, but it takes more than 10 days, so it has little clinical significance.

(6) Serum specific antibody determination, including fluorescent antibodies, complement fixation and hemagglutination inhibition, etc., are helpful for diagnosis, but are not used as routine examinations. Medication: Erythromycin or tetracycline are effective, but because infants and children before 8 years of age take too much tetracycline, it can cause teeth to become permanent yellow-brown, and enamel dysplasia of deciduous and permanent teeth is also common, and can even temporarily hinder bone growth and affect liver and kidney function. For the treatment of this disease, erythromycin is the first choice for children, 20~40mg/kg·day, divided into 4 oral doses, and the course of treatment is up to 2 weeks, which can improve clinical symptoms, reduce lung shadows, and shorten the course of the disease. In severe cases, erythromycin can be added intravenously, 20~30mg/kg·day to 5% glucose, the ratio of medicine to sugar concentration is 1mg:1ml, and the drip rate should be slow, so as not to stimulate local blood vessels and cause phlebitis. If the gastrointestinal reaction of erythromycin is obvious, you can take digestive drugs.!
