Age group characteristics of clinical features and use of epinephrine in children with anaphylaxis who visited emergency department

Methods: We performed a retrospective chart review of 138 children who visited a tertiary care hospital ED from January through December 2018, and were discharged with anaphylaxis as the diagnosis. Anaphylaxis was defined according to the National Institutes of Allergy and Infectious Disease criteria. The children were divided into 4 age groups; infants (< 1 year), preschoolers (1-5 years), schoolers (6-11 years), and adolescents (12-18 years). Clinical features and epinephrine use were compared among the age groups.
