ABSTRACT

Objective:

To analyze the pulmonary function after pneumonia in children over 3 years old.

Methods:

This was an observational study recruiting children discharged from Beijing Children′s Hospital, Capital Medical University between January 1, 2016 and December 31, 2017 with the first diagnosis of pneumonia who were re-examined for pulmonary function within 0.5 to 2.0 years follow-up at outpatient department.Medical records during hospitalization, clinical information, pulmonary function and/or chest imaging examination were collected for analyzing lung function and relevant risk factors.

Results:

A total of 159 eligible patients who were followed up at the outpatient department were recruited, involving 100 patients receiving the lung function examination, and among them, 46 had abnormal lung function.There was no significant correlation between the gender and the pulmonary function after pneumonia ( χ2= 0.975, P=0.323). No correlation was found between the pulmonary function and pneumonia pathogens ( χ2=0.549, P=0.908). Children with severe pneumonia ( χ2=5.154, P=0.023) and abnormal chest imaging after pneumonia ( χ2=4.464, P=0.035) were more likely to have lung dysfunction.Among 74 children over 6 years old, there were 45 cases(60.81%) had pulmonary dysfunction after pneumonia, manifesting as the reduced forced expiration volume in one second (FEV 1), forced vital capacity (FVC), forced expiratory flow at 50% vital capacity, forced expiratory flow at 75% vital capacity, maximum mid-expiratory flow and FEV 1/FVC%.

Conclusions:

Lung dysfunction may occur after pneumonia, manifesting as small airway dysfunction, obstructive ventilation dysfunction and mixed ventilation dysfunction.The gender and etiology of pneumonia are not correlated with lung dysfunction after pneumonia.Children with severe pneumonia and continuous imaging abnormalities are more likely to have lung dysfunction.
