WebThere is little risk of seizures during general anesthesia because anesthetic agents inhibit the firing of neurons, although the anesthetic sevoflurane can rarely precipitate seizures. ... There is generally no increased risk of seizures upon awakening from anesthesia if AEDs have been taken. • If even a single AED dose cannot be given orally ... WebBecause the neuronal signals must pass multiple synapses from the primary, secondary, and tertiary regions of the brain to reach the higher order regions, the anesthetic’s small effects on each synapse add up, so that the effect on rCBF is only observed at the more sensitive higher order regions.
