Anaesthesia management in epilepsy surgery with intraoperative electrocorticography

Area of Science:

• Neurosurgery
• Neurology
• Anesthesiology

Background:

• Epilepsy surgery is a key treatment for drug-resistant epilepsy.
• Accurate identification of the epileptogenic zone is crucial for surgical success.
• Non-invasive methods may be inconclusive, necessitating invasive techniques like intraoperative electrocorticography.

Observation:

• Intraoperative electrocorticography (iEEG) guides epilepsy surgery by mapping the epileptogenic zone.
• Anesthetic agents can potentially interfere with iEEG recordings.
• Careful selection of anesthetics is vital for accurate iEEG interpretation.

Findings:

• This case review focuses on identifying anesthetic drugs suitable for epilepsy surgery involving iEEG.
• Understanding drug effects on iEEG is essential for surgical planning and execution.

Implications:

• Optimizing anesthetic choices can improve the reliability of iEEG in epilepsy surgery.
• This knowledge aids neurosurgeons and anesthesiologists in achieving better patient outcomes.
• Further research into anesthetic-EEG interactions is warranted for epilepsy treatment.
