Seizure occurring during neurosurgery

A seizure occurring during neurosurgery is an acute, paroxysmal neurological complication characterized by abnormal, excessive, and synchronous electrical discharges of cerebral cortical neurons during a cranial operative procedure This condition primarily affects the central nervous system in neurosurgical patients, occurring under general anesthesia or during awake craniotomy with functional cortical mapping Pathophysiologically, it is triggered by direct mechanical manipulation, cortical elec...

A seizure occurring during neurosurgery is an acute, paroxysmal neurological complication characterized by abnormal, excessive, and synchronous electrical discharges of cerebral cortical neurons during a cranial operative procedure Pathophysiologically, it is triggered by direct mechanical manipulation, cortical electrical stimulation, acute cerebral ischemia, regional hypoxia, or abrupt shifts in intracranial pressure and local neurochemical homeostasis Clinically, these events manifest either ...

This condition primarily affects the central nervous system in neurosurgical patients, occurring under general anesthesia or during awake craniotomy with functional cortical mapping Pathophysiologically, it is triggered by direct mechanical manipulation, cortical electrical stimulation, acute cerebral ischemia, regional hypoxia, or abrupt shifts in intracranial pressure and local neurochemical homeostasis

Clinically, these events manifest either as overt motor activity, such as focal or generalized tonic-clonic convulsions, or as subclinical electrographic discharges accompanied by acute physiological instability, including sudden arterial hypertension, tachycardia, increased brain swelling, or elevated end-tidal carbon dioxide
