Changes in Density Spectral Array of BIS VISTA Monitoring System in Epilepsy Surgery

Abstract

We report the case of a patient with drug resistant epilepsy scheduled for amygdalohippocampectomy (AHS). During this type of surgery, Density Spectral Array (DSA) belonging to the Bilateral Bispectral Index (BIS) VISTATM Monitoring System (BVMS) was used. DSA, but no BIS trend, was helpful to detect differences in the power spectrum between both cerebral hemispheres during propofol- remifentanyl-dexmedetomidine anesthesia. This case provides novel evidence to support the clinical utility of DSA in monitoring depth of anaesthesia and sedation.
