Clinical analysis of 4 430 cases of lobar pneumonia in children

Objective To explore the epidemiological characteristics,clinical manifestations,and pathogens of lobar pneumonia in children in recent years so as to provide reference for its diagnosis and treatment.Methods We made a statistical analysis of the clinical data,laboratory and imaging findings of 4 430 cases of lobar pneumonia in children hospitalized in Xi'an Children's Hospital between January 1,2009 and December 31,2011 to explore the outbreak season,gender-age correlation,pathogens,and imaging features of children lobar pneumonia.Results The incidence of children lobar pneumonia was significantly higher in winter than in the other seasons,in 0-3 age group than the other groups,and in boys than in girls(all P0.05).Serum virus antibodies were detected in 72.78% of the children and positive Mycoplasma pneumoniae antibodies were detected in 47.13%.Chest CT examination showed a higher incidence of bilateral lesions than that of unilateral ones(P0.05).Conclusion Lobar pneumonia in children occurs more often in winter,in children aged 0-3 years old,and in boys.Viral infection accounts for the largest proportion of the etiology,followed by Mycoplasma pneumoniae infection.Lung imaging shows that bilateral lesions are the most common.
