Abstract: 【Objectives】 To analyze the clinical features in the recovery phase of mycoplasma pneumoniae pneumonia(MPP) with pulmonary atelectasis complication and to evaluate the factors of sequelae may occur after mycoplasma pneumoniae pneumonia by analysis of the examinations of high-resolution computed tomogramphy (HRCT) and pulmonary function. 【Methods】 109 cases of pediatric MPP with pulmonary atelectasis complication had been selected from 1 166 patients who were treated in Beijing Pediatric Hospital between May 2006 and May 2007.After telephone appointments and parental authorizations,thirty-six children were examined with HRCT and/or with pulmonary function after an interval of 1.0 to 1.4 years. 【Results】 1)The incidence of pediatric MPP with pulmonary atelectasis complication in hospitalized patients was no significant difference in age distributions (P>0.05).2) 23 patients had been identified with abnormal lung appearance by using HRCT imaging in 36 cases of pediatric MPP with pulmonary atelectasis complication,corresponding to a rate of 63.9%.3)The patients were divided into "Abnormal HRCT Group" and "Normal HRCT Group" according to their HRCT examinations.Comparative studies were carried out between two groups,and showed significant differences (P<0.05) in age distribution,duration of fever and cough.There was a significant difference in the therapeutically effect of fiber-optical bronchoscope-assisted washing treatment between the group within 20 days and more than 20 days of illness (P<0.05).4) The pulmonary functions in 27 cases were still abnormal with obstruction of ventilation function in 16 cases and with complexed/mixed ventilation functional obstructions with blocking as primary obstacle in 1 case. 【Conclusions】 Careful follow-up is important for mycoplasma pneumonia in younger children or fever and cough is longer.Early applying the fiber-optical bronchoscope-assisted washing treatment may reduce the sequelae.The pulmonary function should be examined with regular.
