RESUMEN
INTRODUCTION: Febrile seizures are one of the most frequent reasons why patients visit the healthcare specialist. Up until now, patients with complex febrile seizures (CFS) have been hospitalised, bearing in mind the higher percentages of epilepsy and acute complications that were classically reported. Today there are studies that back the idea of being less invasive in the management of these patients. AIMS. To describe the characteristics of patients hospitalised due to CFS and to propose a new protocol to be followed in dealing with such cases. PATIENTS AND METHODS: The medical records of patients hospitalised because of CFS (January 2010-December 2013) were analysed retrospectively. Epidemiological and clinical data are presented, together with information from complementary tests and about development. RESULTS: CFS account for 4.2% of all neuropaediatric cases of admittance to hospital in (67 patients). Mean age at the time of the event: 25 months. A pathological family history existed in 47% of cases, and 31% had a previous personal history of febrile seizures. The CFS lasted less than five minutes in 54% of patients; there were also recurrences, most of them with a total of two crises and during the first day (CFS due to recurrence are the most frequent). None of the complementary tests that were carried out were of any use as a diagnostic aid during the acute phase. During their follow-up, five patients presented complications. Patients with a family history of febrile seizures presented a higher risk of epilepsy or recurrence (p = 0.02), with no significant differences as regards age, number of seizures, febrile interval, epileptic status or type of CFS. CONCLUSIONS: The CFS are not associated with greater acute complications, and the complementary examinations do not allow high-risk patients to be distinguished at an early stage. Hospitalising them could be avoided in the absence of other clinical signs and symptoms, and thus be limited to selected cases.
TITLE: Crisis febriles complejas: debemos cambiar nuestro modo de actuacion?Introduccion. Las convulsiones febriles son una de las causas mas frecuentes de consulta. Hasta ahora, los pacientes con convulsiones febriles complejas (CFC) deben ingresar, dado el mayor porcentaje de epilepsia y complicaciones agudas descrito clasicamente. En la actualidad hay estudios que apoyan ser menos invasivos en el abordaje de estos pacientes. Objetivo. Describir las caracteristicas de los pacientes ingresados por CFC y proponer un nuevo protocolo de actuacion. Pacientes y metodos. Analisis retrospectivo de historias clinicas de ingresados por CFC (enero de 2010-diciembre de 2013). Se ofrecen datos epidemiologicos, clinicos, pruebas complementarias y evolucion. Resultados. Las CFC suponian un 4,2% de los ingresos de neuropediatria (n = 67). Edad media al evento: 25 meses. El 47% tenia antecedentes familiares patologicos, y el 31%, antecedentes personales de convulsion febril previa. En el 54% de los pacientes, la CFC duro menos de cinco minutos; hubo recurrencia, la mayoria con un total de dos crisis y durante el primer dia (las CFC por recurrencia son las mas frecuentes). De las pruebas complementarias realizadas, ninguna de ellas sirvio como apoyo diagnostico en el momento agudo. Durante su seguimiento, cinco pacientes presentaron complicaciones. Los pacientes con antecedentes familiares de convulsiones febriles presentan mayor riesgo de epilepsia o recurrencia (p = 0,02), sin diferencias significativas respecto a la edad, numero de crisis, intervalo de fiebre, estado epileptico o tipo de CFC. Conclusiones. Las CFC no asocian mayores complicaciones agudas; las exploraciones complementarias no permiten discriminar precozmente a los pacientes de riesgo. Su ingreso podria evitarse en ausencia de otros signos clinicos y limitarse a casos seleccionados.
