Potenciales evocados visuales en cuidados intensivos

Abstract

El objeto de este trabajo es comprobar si los potenciales evocados visuales en los pacientes hospitalizados en la unidad de cuidados intensivos (UCI) y bajo sedación varían en sus parámetros de amplitud y latencia, según se realicen con los ojos abiertos o cerrados. Se realizaron ocho potenciales evocados visuales en pacientes hospitalizados en la UCI, con alteración de su estado de conciencia por sedación farmacológica, sin compromiso neurológico; según la historia clínica y las patologías de tratamiento no eran de origen neurológico. No se encontraron diferencias en cuanto a los parámetros de amplitud y velocidad de conducción (latencia) cuando se realizaban con los ojos abiertos y cerrados. Sin embargo llama la atención la mejoría en la velocidad que oscila alrededor de 1 % y que si bien clínicamente no altera el resultado final de normalidad si representa un incremento de 1,5 ms de conducción nerviosa al realizarse con los ojos cerrados. Los potenciales evocados pueden continuar realizándose sin tener en cuenta la postura de los párpados en los pacientes bajo sedación en UCI, teniendo así la certeza de que los datos obtenidos reflejan la integridad de la vía visual en sujetos que por su estado de conciencia no pueden colaborar con otros datos clínicos.
