Background: Status dystonicus is characterized by frequent or prolonged severe episodes of generalized dystonia. The phenomenology, etiology, and outcome is heterogenous and poorly characterized, making a standardized management approach challenging. We characterized demographics of children with status dystonicus in British Columbia admitted to the pediatric intensive care unit (PICU), management patterns, and outcomes. Methods: Clinical records at our PICU were searched via ICD-10 codes. We included cases admitted 2014-2024 who had dystonia severity grade 3-5, dystonia worse than baseline, and age >30 days old. Results: Seventy-nine records were screened; 41 admissions from 19 unique patients were included. Mean age was 7.6±4.2 years; 53% were female. Most unique patients had a genetic etiology (n=8, 42%). The presenting complaint per admission was often not dystonia (n=24, 59%); infection was the most common trigger (n=23, 56%) followed by pain (n=6, 15%). Patients received several anti-dystonia medications (mean 6.9±2.5), including clonidine, benzodiazepines, ketamine, and others. Mean PICU stay was 11.0±10.8 days; 37% had multiple PICU admissions. Two patients (4.9%) died from status dystonicus complications. Conclusions: Status dystonicus is a life-threatening emergency commonly triggered by pain and infection in patients with dystonia. Given the considerable morbidity and mortality, multi-disciplinary teams should consider standardized treatment guidelines for these complex patients.
