Objective:To comprehensively analyze the clinical characteristics,classification of causes,treatment methods,and outcomes of pediatric convulsions in the emergency department,providing a scientific basis for the diagnosis and treatment of pediatric convulsions and optimizing emergency management for these cases.Methods:The clinical data of 18 217 children with convulsions in the emergency department of Capital Institute of Pediatrics' Children's Hospital from January 1,2016 to December 31,2020 were retrospectively analyzed.Results:A total of 18 217 children were admitted to the emergency department due to convulsions,accounting for 2.3% of all visits.Among them,58.7% cases were male and 41.3% cases were female,with an average age of (2.00±0.03) years.The main age was 1 to 3 years old (54.2%).Generalized convulsions were the primary type (82.3%),with focal seizures accounting for 17.7%.Most convulsions lasted less than 5 minutes (82.4%),and approximately 55.2% of the patients could self-resolve.Febrile convulsions were the primary cause (69.2%),followed by benign convulsions with mild gastroenteritis (11.7%) and epilepsy (10.5%).Regarding treatment,54.0% of the children recovered without medication.In the triage system of "three zones and four levels," the usage rate of anticonvulsants in the red zone was 93.1%,with 21.6% requiring combined treatment.After treatment,48.2% of the children returned home,92.2% showed improvement or recovery,and the mortality rate was extremely low at only 0.03%.Conclusion:Febrile convulsions are the main cause of pediatric convulsions in the emergency department,and an efficient triage system play an important role in improving treatment response.Different treatment zones and outcomes vary,providing important reference for optimizing emergency management.
