Question 1
Which inhaled anesthetic causes the GREATEST suppression of cortical evoked potentials at equivalent concentrations?
Correct Answer:
Isoflurane
Question 2
Nitrous oxide specifically affects evoked potentials by:
Correct Answer:
Reducing amplitude of cortical responses, particularly affecting MEPs significantly
Question 3
The optimal anesthetic protocol for intraoperative neurophysiological monitoring (IONM) when MEP monitoring is required is:
Correct Answer:
Total intravenous anesthesia (TIVA) with propofol and remifentanil, avoiding NMB
Question 4
How do opioids affect intraoperative evoked potentials?
Correct Answer:
They have minimal effect on SSEPs, MEPs, and BAEPs at clinical doses
Question 5
Etomidate transiently increases SSEP amplitudes because it:
Correct Answer:
Decreases synaptic inhibition in the somatosensory cortex
