Manejo y factores de riesgo de mortalidad del estatus epiléptico: estudio retrospectivo / Status epilepticus management and mortality risk factors: A retrospective study

Introducción: El estatus epiléptico (SE, por sus siglas en inglés) es una urgencia neurológica con altas tasas de mortalidad. En este estudio analizamos el manejo del SE e identificamos factores de riesgo de mortalidad en los que realizar intervenciones de mejora o modificaciones en los protocolos de actuación hospitalarios. Métodos: Retrospectivamente se analizaron los datos demográficos de tratamiento y pronóstico de 65 pacientes (59 [44,5-77] años, 53,8% mujeres) que ingresaron en un hospital terciario cumpliendo los criterios de SE de la ILAE 2015, durante un periodo de 18 meses. Resultados: Treinta (46,2%) pacientes tenían antecedentes de epilepsia. Las causas más frecuentes de SE fueron enfermedad cerebrovascular (27,7%) e infección sistémica (16,9%). Se registraron desviaciones respecto al tratamiento habitual: la administración de las benzodiazepinas como primer fármaco solo en 33 (50,8%) pacientes, la combinación de 2 benzodiazepinas en 7 (10,8%) pacientes y el uso off-label de lacosamida en 5 (7,7%) pacientes. El electroencefalograma (EEG) fue realizado únicamente en 26 (40%) pacientes y solo 5 EEG (7,7% de pacientes) en las primeras 12 h. La tasa de mortalidad fue del 21,5%. Ictus agudo y complicaciones cerebrovasculares se asociaron con mortalidad, mientras que epilepsia previa e ingreso en la unidad de cuidados intensivos (UCI) fueron factores de buen pronóstico (p < 0,05). Conclusiones: Para mejorar el manejo del SE y reducir la tasa de mortalidad, sería recomendable implementar actividades formativas dirigidas a los profesionales del departamento de urgencias, así como el ingreso electivo en la UCI para pacientes con factores de riesgo (primera crisis epiléptica, con ictus agudo o complicaciones cardiovasculares).

Introduction: Status epilepticus (SE) is a neurological emergency with relatively high mortality rates. In this study, we analysed the management of SE and identified mortality risk factors that may be addressed with educational interventions or modifications to hospital protocols. Methods: In this retrospective study, we analysed demographic, treatment, and outcome data from 65 patients (mean age, 59 years [range, 44.5-77]; 53.8% women) who were admitted to our tertiary hospital during an 18-month period and met the 2015 International League Against Epilepsy criteria for SE. Results: Thirty patients (46.2%) had history of epilepsy. The most frequent causes of SE were cerebrovascular disease (27.7%) and systemic infection (16.9%). The following deviations were observed in the administration of the antiepileptic drugs: benzodiazepines were used as first option in only 33 (50.8%) patients; the combination of 2 benzodiazepines was recorded in 7 cases (10.8%); and lacosamide was used as an off-label drug in 5 patients (7.7%). Electroencephalography studies were performed in only 26 patients (40%); and only 5 studies (7.7% of patients) were performed within 12 hours of seizure onset. The mortality rate was 21.5%. Acute stroke and cerebrovascular complications were associated with higher mortality rates, while previous history of epilepsy and admission to intensive care were related to better prognosis (P <.05). Conclusions: To improve SE management and reduce mortality rates, training activities targeting emergency department physicians should be implemented, together with elective intensive care admission for patients with multiple mortality risk factors (eg, absence of history of epilepsy, acute stroke, or cardiovascular complications).
