EEG changes with carotid sinus baroreflex during carotid endarterectomy.
We describe EEG changes in three patients in whom the carotid sinus baroreflex was precipitated during carotid endarterectomy. In all instances, the EEG showed diffuse attenuation and slowing of the baseline anesthetic pattern in association with bradyvcardia. This can help alert the surgeon to the changes occurring as a result of the cardioinhibitory carotid sinus baroreflex and guide appropriate timely intervention.
