Introduction: This article focuses on EEG findings during general anesthesia with a sevoflurane-based technique. Inhaled ether anesthetics have complex effects on the CNS and, despite widespread use, their mechanism of action is not fully understood. While the primary hypnotic effect is the result of increased GABA-A activity, sevoflurane’s effects are much more widespread. … [Read more...] about EEG Signature(s): Sevoflurane

SNACC Medically Challenging Case: Anesthetic considerations & challenges during neuromonitoring in a patient with cervical spinal cord AVM
Introduction: Intraoperative neuromonitoring (IONM) provides valuable data for managing patients with spinal cord arteriovenous malformations (AVMs). Previous literature shows that patients who are not treated for their spinal cord AVMs can experience lasting and progressive disabilities.1 The use of IONM and provocative testing, such as the pre-embolization lidocaine … [Read more...] about SNACC Medically Challenging Case: Anesthetic considerations & challenges during neuromonitoring in a patient with cervical spinal cord AVM
EEG Case: Nociceptive EEG Changes under General Anesthesia
Introduction: Prior Electroencephalogram (EEG) articles have focused on the pharmacologic effects of ketamine, propofol, and nitrous oxide on intraoperative EEG. This article shifts the focus to nociceptive EEG changes occurring under general anesthesia. These EEG changes include beta arousal, delta arousal, and alpha dropout.1 Beta arousal refers to increased power in the … [Read more...] about EEG Case: Nociceptive EEG Changes under General Anesthesia

SNACC Medically Challenging Case: Functional Pituitary Macroadenoma: Anesthetic Considerations
Introduction Functional pituitary macroadenomas, although rare,1 present a unique challenge for anesthesiologists. These tumors, arising from the anterior pituitary gland, exhibit an expansive growth pattern (often exceeding 10 mm in diameter) and have the potential for endocrine dysregulation. Their functional nature further complicates the perioperative management, as … [Read more...] about SNACC Medically Challenging Case: Functional Pituitary Macroadenoma: Anesthetic Considerations
