Anaesthesia for Cortical Stimulation Guided Epileptic Foci Removal: A Case Report

A 15yr old patient with diagnosis of frontal gliosis having refractory seizures, on treatment with antiepileptics was admitted for cortical stimulation guided removal of epileptic foci. The craniotomy was done and a 32 grid subdural electrode was placed to identify the ictal onset zone with cortical stimulation to identify the functional areas. The patient received the relaxant for intubation after which the mapping and further stimulation was done with continuous infusion of dexmedetomidine. After the surgery the pre-resection evaluation was done for the epileptic foci and after two days the patient was again taken for surgery and the corresponding foci was resected.
