Objective To analyse the changes and clinical significance of pulmonary function in children with mycoplasma pneumoniae pneumonia(MPP) during acute and convalescent periods. Methods A total of 60 children aged 3 to 10 years with acute MPP in Yan'an People's Hospital were selected as observation group from June 2015 to June 2017,and 60 healthy children were selected as control group at the same time.All children took routine pulmonary function test,and the observation group was followed up to the recovery period(on the third weeks after the onset). Results The indexes of pulmonary function ventilation(FVC,FEV1,FEV1/FVC,PEF,MEF75,MEF50,MEF25,MMEF) in the acute stage of MPP were significantly lower than those in normal control group(t=-6.719,-6.835,-1.754,-6.171,-6.926,-5.661,-6.889,-6.874,P<0.05).And all indexes in the recovery period obviously increased than the acute stage.Compared with the normal control group,FVC,FEV1,FEV1/FVC and PEF in the recovery period of MPP children recovered basically,while MEF75,MEF50,MEF25 and MMEF were still lower(t=-2.306,-1.995,-3.305,-2.557,P<0.05). Conclusions The pulmonary function of MPP children have different degrees of damage in the acute stage.All the indexes of large airway in the recovery period are basically recovered,but the indexes of small airway still not rise to the normal level.Therefore,it is necessary to dynamically monitor lung function in clinical practice,which is of great significance in the evaluation and prognosis of treatment of MPP children.
