Mycoplasma pneumonia is an acute respiratory infection caused by Mycoplasma pneumoniae with pneumonia, and among the pathogens previously called primary atypical pneumonia, Mycoplasma pneumoniae is the most common. It can cause epidemics, accounting for about 10% of all types of pneumonia, and severe mycoplasma pneumonia can also lead to death. Diagnosis of clinical symptoms such as headache, fatigue, myalgia, nasopharyngeal lesions, cough, chest pain, purulent and bloody sputum, pulmonary x-ray findings, and laboratory tests such as condensation tests are helpful. 1. Medical history and symptoms: the onset is relatively slow, most of them are pharyngitis, bronchitis manifestations, and 10% are pneumonia. Symptoms mainly include chills, fever, fatigue, headache, malaise, irritating dry cough, accompanied by sticky sputum, purulent sputum, and even bloody sputum. There may also be extrapulmonary manifestations such as nausea, loss of appetite, vomiting, diarrhea and arthralgia, myocarditis, pericarditis, hepatitis, peripheral neuritis, meningitis, and skin maculopapular rash. 2. Physical examination findings: nasopharyngeal and conjunctival hyperemia, edema, cervical lymphadenopathy, rash; Chest signs are often subtle, and pulmonary auscultation may show fine crackles, occasional pleural friction rub, and pleural effusion. Treatment of erythromycin, crosssamycin and tetracycline is effective and can shorten the course of the disease. erythromycin 0.5 g every 8 hours; The gastrointestinal reaction of crosssamycin is mild, there are few other side effects, the effect is similar to erythromycin, the dosage is 1.2~1.8g/d, divided oral dose; Tetracycline 0.5 g every 6 hours. Treatment should be continued for 2~3 weeks to avoid recurrence. When the cough is severe, codeine 15~30mg can be used, 3 times a day. The preventive effect of mycoplasma vaccine is inconclusive, and intranasal administration of live attenuated vaccine has a certain preventive effect.
