Maintenance and surgical considerations
Maintenance should ensure that the patient does not move once in Mayfield pins and patient will be able to participate in a basic neurological exam upon emergence.
Inhaled anesthetics should be avoided due to dampening of neuromonitoring signals. Reasonable considerations would be TIVA (propofol/remifentanil) or a combination of propofol/sevoflurane.
If MEP, EMG, or BAERs are needed, then patient cannot be fully paralyzed. Generally must maintain 2+ twitches on TOF monitoring. Vecuronium infusions should be considered for smoother signaling monitoring. If SSEPs or EEG, then patient can be fully paralyzed.
As these are painful procedures, consider titrating fentanyl up to 5 mcg/kg.
