ABSTRACT

Introducción: El estado epiléptico superrefractario (EESR) es una entidad neurológica con una importante morbimortalidad, en la que se dispone de pocas opciones terapéuticas. La sedación inhalatoria con isoflurano es un tratamiento de uso compasivo actualmente en las unidades de cuidados intensivos españolas. Existe poca documentación sobre su utilidad en el tratamiento del estado epiléptico refractario y superrefractario, pero parece ser una alternativa terapéutica útil y segura para esta patología. Casos clínicos: Este artículo es una revisión de tres casos de EESR tratados con isoflurano. Se evaluó el control de las crisis epilépticas por isoflurano mediante monitorización electroencefalográfica. Otras variables evaluadas han sido el tiempo transcurrido hasta el control de las crisis, la supervivencia, el resultado funcional y la aparición de complicaciones secundarias al isoflurano. En los tres casos revisados, el isoflurano se mostró efectivo para el control de las crisis epilépticas en pacientes afectados por EESR. El control de las crisis epilépticas se logró rápidamente, y se pudo titular fácil y rápidamente la mínima dosis que obtenía el patrón burst-suppression. A pesar del control de la epilepsia, se objetivó una elevada mortalidad (66,66%). Esto se explica tanto por la mortalidad del EESR como por las patologías subyacentes de los pacientes fallecidos. El uso de isoflurano no presentó complicaciones. Conclusión: Con los resultados obtenidos, es factible pensar que el uso de isoflurano no se relaciona con las lesiones en el sistema nervioso central descritas en otros artículos, y se puede considerar que este tratamiento es efectivo y seguro para el control del EESR.(AU)


Introduction: Super-refractory status epilepticus (SRSE) is a neurological condition with an important morbidity and mortality rate, for which few therapeutic options are available. Inhalation sedation with isoflurane is currently a compassionate-use treatment in Spanish intensive care units. Little has been written about its usefulness in the treatment of refractory and super-refractory status epilepticus, but it appears to be a useful and safe therapeutic alternative for this condition. Case reports: This article reviews three cases of SRSE treated with isoflurane. The capacity of isoflurane to control seizures was assessed by electroencephalographic monitoring. Other variables assessed were time to seizure control, survival, functional outcome and occurrence of complications secondary to isoflurane. In the three cases reviewed, isoflurane proved to be effective for seizure control in patients affected by SRSE. Seizure control was accomplished quickly and the minimum dose required to obtain a burst-suppression pattern was titrated easily and rapidly. Despite controlling epilepsy, high mortality was observed (66.66%). This is explained by both the mortality of SRSE and the underlying pathologies of the patients who died. The use of isoflurane did not give rise to any complications. Conclusion: With the results obtained, it is feasible to think that the use of isoflurane is not related to lesions in the central nervous system reported in other articles, and this treatment can be considered effective and safe for the control of SRSE.(AU)

ABSTRACT

Objective. To compare oxygen saturation index (rSO2) obtained simultaneously in two different brachial muscles. Design. Prospective and observational study. Setting. Intensive care unit. Patients. Critically ill patients with community-acquired pneumonia. Interventions. Two probes of NIRS device (INVOS 5100) were simultaneously placed on the brachioradialis (BR) and deltoid (D) muscles. Variables. rSO2 measurements were recorded at baseline (ICU admission) and at 24h. Demographic and clinical variables were registered. Pearson's correlation coefficient was used to assess the association between continuous variables. The consistency of the correlation was assessed using the intraclass correlation coefficient (ICC) and Bland–Altman plot. The predictive value of the rSO2 for mortality was calculated by ROC curve. Results. Nineteen patients were included with an ICU mortality of 21.1%. The rSO2 values at baseline and at 24h were significantly higher in D than in BR muscle. Values obtained simultaneously in both limbs showed a strong correlation and adequate consistency: BR (r=0.95; p<0.001; ICC=0.94; 95% CI: 0.90–0.96; p<0.001), D (r=0.88; p=0.01; ICC=0.88; 95% CI: 0.80–0.90; p>0.001) but a wide limit of agreement. Non-survivors had rSO2 values significantly lower than survivors at all times of the study. No patient with rSO2 >60% in BR died, and only 17.6% died with an rSO2 value >60% in D. Both muscles showed consistent discriminatory power for mortality. Conclusion. Both BR and D muscles were appropriate for measuring rSO2 (AU)


Objetivo. Comparar el índice de saturación tisular de oxígeno (rSO2) medido de forma simultánea en 2 diferentes músculos braquiales. Diseño. Estudio prospectivo, observacional. Ámbito. Servicio de Medicina Intensiva. Pacientes. Críticos con neumonía comunitaria. Intervenciones. Dos sensores con tecnología NIRS (INVOS™ 5100) fueron ubicados de forma simultánea en los músculos braquiorradial (BR) y deltoides (D). Variables. Las mediciones del rSO2 se efectuaron al ingreso (basal) y a las 24h. Se registraron los datos demográficos y clínicos. La correlación de Pearson se utilizó para estudiar la asociación entre variables continuas. La concordancia de la correlación fue valorada mediante el coeficiente de correlación intraclase (ICC) y el análisis de Bland-Altman. El valor predictivo de rSO2 para mortalidad fue calculado mediante curva ROC. Resultados. Se incluyeron 19 pacientes con una mortalidad de 21,1%. El valor basal y a las 24h de rSO2 fue significativamente mayor en D respecto del BR. Los valores obtenidos de forma simultánea en ambos miembros evidenciaron una buena correlación y una adecuada concordancia: BR (r=0,95; p<0,001. ICC=0,94; IC 95%: 0,90-0,96; p<0,001), D (r=0,88; p=0,01. ICC=0,88; IC 95%: 0,80-0,90; p<0,001), así como un amplio rango de concordancia. Los fallecidos presentaron valores de rSO2 significativamente menores que los supervivientes en todos los momentos del estudio. Ningún paciente con rSO2>60% en BR falleció, y solo el 17,6% fallecieron con un rSO2>60% en D. Ambos músculos evidenciaron un buen poder de discriminación para mortalidad. Conclusiones. Tanto el músculo BR como el D fueron apropiados para la medición del rSO2 (AU)
