Tres nuevas estrategias para mejorar la precisión de la estimulación vestibular calórica monotérmica

Abstract

Resumen Objetivo Encontrar una forma de estimar el valor de paresia canalicular (PC) a traves de la estimulacion vestibular calorica monotermica (EVCM) que pueda utilizarse en cualquier laboratorio, controlando el error que se produce al utilizarla. Metodo Se incluyo en este estudio a 2.304 pacientes de nuestro servicio a los cuales se les realizo una videonistagmografia con pruebas caloricas entre 2003 y 2011. El calculo de la PC se realizo de 3 formas diferentes: utilizando los valores de las 4 estimulaciones caloricas (forma bitermica) o exclusivamente con los 2 valores de una misma temperatura (formas monotermica caliente y fria respectivamente). Se estudiaron 3 estrategias para mejorar la precision de la EVCM: analisis de variables que empeoran la prediccion, delimitacion de un area gris de prediccion deficiente y localizacion de un punto de separacion entre sanos y enfermos de maxima utilidad. Resultados 1) Corregir la formula de Jongkees con el valor del nistagmo espontaneo permite incluir como candidatos a la EVCM a sujetos con nistagmo espontaneo o inversion nistagmica. 2) Establecer una zona gris de prediccion deficiente evita aproximadamente el 38% de las estimulaciones bitermicas realizadas, con una sensibilidad y especificidad del 95%. 3) La maxima utilidad de la EVCM se obtiene al considerar como funcion vestibular normal la de sujetos con valores de EVCM caliente menores o iguales al 16%, suponiendo patologica una asimetria mayor del 20%. Conclusion Las nuevas herramientas estadisticas permiten a los clinicos tomar decisiones que afecten al manejo de sus pacientes basados en los resultados de la EVCM.
