BACKGROUND: Status epilepticus (SE) is a neurological emergency requiring rapid, stepwise treatment. In Japan, the Guidelines for the Treatment of Pediatric Status Epilepticus 2023 (GL2023) were published; however, real-world practice following their publication remains unclear.
METHODS: We conducted a nationwide, cross-sectional web-based survey of pediatric neurologists between January and March 2025. One representative from each institution reported institutional practices for the in-hospital management of pediatric SE. Institutions were stratified by annual SE case volume (≥20 vs. ≤19 cases). General management strategies, antiseizure medication selection, electroencephalography (EEG) utilization, and approaches to refractory and super-refractory SE (RSE and SRSE) were analyzed.
RESULTS: A total of 136 institutions responded. Most institutions reported referring to GL2023 and initiating first-line treatment within 10 min of hospital arrival. Midazolam was the most commonly used first-line drug, with widespread use of non-intravenous routes. Phenytoin or fosphenytoin remained the most commonly selected second-line drug, followed by phenobarbital. For RSE, anesthetic coma therapy with midazolam and barbiturates was used at comparable frequencies. Overall, antiseizure medication selection did not differ by institutional case volume. In contrast, institutions managing ≥20 cases annually more frequently reported having institution-specific protocols, utilizing EEG in the emergency department, administering repeat doses of benzodiazepines, and having experience with advanced therapies for SRSE.
CONCLUSIONS: Pediatric SE management in Japan emphasizes rapid treatment and flexible administration routes. Institutional experience is associated with differences in EEG utilization, protocol development, and SRSE management. Further improvement will require continued evidence generation, timely treatment implementation, and reduction of institutional disparities.
