RESUMO
Resumen Las crisis convulsivas tienen una alta incidencia en la etapa neonatal, representando la principal manifes tación de disfunción neurológica. Ciertas condiciones fisiológicas del cerebro neonatal facilitan su aparición. Su diagnóstico puede ser un reto debido a que su semio logía no es tan clara comparado con niños mayores, y además, es necesario la confirmación por medio de EEG continuo o aEEG. Su reconocimiento oportuno es muy importante para un adecuado tratamiento y así evitar un impacto negative en el pronóstico a largo plazo. En la siguiente revisión, recapitulamos la fisiopatología, las causas y la clasificación de las crisis convulsivas neo natales, además de su correcto abordaje y las mejores opciones terapéuticas para su tratamiento dependiendo de la causa.
Abstract Seizures have a high incidence in the neonatal stage, being the main manifestation of neurological dysfunc tion. Certain physiological conditions of the neonatal brain facilitate its appearance. Its diagnosis can be a challenging because its semiology is not as clear as in older children, furthermore, confirmation by either EEG or aEEG is necessary. Its timely recognition is very im portant for adequate treatment and thus avoid a nega tive impact on the long-term outcome. In the following review, we recapitulate the pathophysiology, causes, and classification of neonatal seizures, as well as their correct approach and the best therapeutic options for their treatment depending on the cause.
RESUMO
El estatus epiléptico (SE) en pediatría es una emergencia neurológica ya que presenta morbimortalidad. Existen diferencias con los adultos y su reconocimiento puede ser más difícil especialmente a edades tempranas. Se han precisado distintas etapas en el SE y se ha acortado el tiempo en su definición, lo anterior con el objetivo de dar opciones terapéuticas más precoces. Existen diversos protocolos terapéuticos y en todos ellos las benzodiazepinas constituyen la primera etapa, incluyendo la terapia pre-hospitalaria que si es bien realizada puede evitar la progresión al SE en un paciente con una crisis epiléptica. En estatus refractario y super refractario la evidencia es menor y el rol de los anestésicos es protagónico con la necesidad de un manejo integral en una unidad de cuidados intensivos pediátricos (UCIP) y con un monitoreo electroencefalográfico continuo (cEEG), este último resulta ser un recurso limitado especialmente en el sistema público. Palabras Claves: estado epiléptico, monitoreo EEG continuo, pacientes pediátricos, anticonvulsivantes.
Status epilepticus (SE) in pediatric patients is a neurological emergency because it is associated to morbidity and mortality. There are differences between children and adults, making its recognition harder, especially in early ages. Different stages have been defined in SE and the time has been shortened in its definition, with the aim to give earlier therapeutic options. There are several protocols and in all of them benzodiazepines are the first option, even in the pre-hospital scenario, which, if managed well, can avoid progression to SE in a patient with an epileptic seizure. In refractory SE the evidence is poor and the role of anesthetics is more important with the need for an comprehensive management in a pediatric intensive care unit (PICU) and with continuous electroencephalographic monitoring (eEEG), the latter being a limited resource especially in our public health system. Key words: Status epilepticus, pediatric patients, continuous EEG monitoring, antiepileptic drugs.
RESUMO
INTRODUÇÃO: O estado de mal epiléptico (EME) é subdiagnosticado, especialmente as formas clínicas com sinais motores sutis ou apenas com alteração da consciência. É uma emergência neurológica que necessita diagnóstico imediato e a tratamento agressivo e para prevenir lesão neuronal. OBJETIVOS: Revisar, discutir e propor protocolo para o tratamento desta condição. METODOLOGIA: A literatura foi selecionada a partir de pesquisa nas bases de dados MEDLINE e PUBMED. RESULTADOS: Propomos um protocolo utilizando diazepam, fenitoína, fenobarbital, midazolam, thiopental e pentobarbital ainda nos casos refratários topiramato ou levetiracetam. CONCLUSÕES: Um protocolo estruturado para a investigação da etiologia e tratamento do EME é necessário e possibilita melhores chances de evolução dos casos.
INTRODUCTION: Status epilepticus (SE) is an under recognized medical emergency, especially subtle SE or clinical presentation mostly with conscience disturbance (nonconvulsive SE). It is a medical emergency that requires immediate and aggressive diagnoses and treatment. OBJECTIVES: Review, discuss and a protocol suggestion for treatment. METHODOLOGY: Literature publication was selected from MEDLINE and PUBMED. RESULTS: A protocol with diazepam, phenytoin, phenobarbital, midazolam, thiopental and pentobarbital, including topiramate and levetiracetam for refractory cases was proposed. CONCLUSIONS: A standardized protocol for SE work-up and treatment is useful and probably improves outcome.
