Electrocorticogram changes during corpus callosotomy for uncontrolled symptomatic generalized epilepsy

Dexmedetomidine for Electrocorticography in Patients With Lennox-Gastaut Syndrome Presenting for Epilepsy Surgery: A Case Report

We report the anesthetic management of 2 patients with Lennox-Gastaut syndrome presenting for respective epilepsy surgery with intraoperative electrocorticography. Electrocorticography is a useful tool to guide the localization of the epileptogenic focus for surgical resection in epilepsy surgery. Drug interactions, proconvulsant or anticonvulsant activity of the anesthetics, and anesthetic influence on intraoperative electrocorticography are the primary concerns to be addressed in these patients. We observed that dexmedetomidine-based anesthesia facilitates intraoperative electrocorticography monitoring. Dexmedetomidine, by decreasing the requirements of other anesthetic agents, offers better recovery profile and pain relief with minimal respiratory depression in patients undergoing disconnective epilepsy surgeries.
