Which type of anesthesia is considered best for electrocorticography in the operating room?

The use of desflurane for anesthesia during electrocorticography (ECoG) is considered optimal due to its unique pharmacokinetic profile. Desflurane has a rapid onset and offset of action, which allows for precise control over anesthetic depth. This is especially valuable during ECoG, a procedure that requires real-time monitoring of brain activity while minimizing the effects of anesthesia on the cerebral function.

Desflurane enables quick adjustments to the depth of anesthesia, permitting clearer assessments of brain responses when stimulating cortical areas. Its low solubility in blood results in faster recovery times, making it advantageous for procedures where neurological evaluation is critical. The ability to rapidly adjust anesthetic depth is particularly important in ECoG to maintain the balance between adequate anesthesia and the ability to elicit and monitor electrical activity from the brain.

In contrast, other anesthetics such as sevoflurane, isoflurane, and propofol, while effective for general anesthesia, do not provide the same level of quick adjustability and may have more profound impacts on brain activity monitoring when compared to desflurane. This makes desflurane the preferred choice for this specific type of monitoring and surgical procedure.
