Propofol:
Induction Agent. Bolus will decrease amplitude of cortical responses but used as an infusion will not affect cortical SSEPs to any large degree.
Etomidate:
Induction agent. Will increase cortical response amplitude
Ketamine:
Induction Agent. Will increase cortical response amplitude
Inhalation Agents:
Gases: At .75-1 MAC will decrease amplitude and increase SSEPs. Agents also abolish TcMEP responses greater than 0.5 MAC.
