  Purpose

When patients have spinal surgery, electrodes are placed on the body to measure motor evoked potentials (MEP) and somatosensory evoked potentials (SSEP). Many hospitals only use IV anesthesia because they feel that measuring MEP and SSEP is easier using IV anesthesia. At this hospital the investigators typically use inhaled anesthesia and are able to successfully measure MEP and SSEP. This is a study to find out if one method of anesthesia is better than the other for measuring MEP and SSEP.

Primary Outcome Measures:
  • Amplitude Required to Elicit the MEP [ Time Frame: at time of surgery ] [ Designated as safety issue: No ]
    Compare the data obtained from neuromonitoring including the amplitude required to elicit the MEP from patients receiving general anesthesia with an inhalational anesthetic agent to those receiving total intravenous anesthesia (TIVA).


Secondary Outcome Measures:
  • Amplitude of the SSEPs [ Time Frame: day of surgery ] [ Designated as safety issue: No ]
    SSEPs (somatosensory evoked potentials) are most commonly elicited by bipolar transcutaneous electrical stimulation applied on the skin over the trajectory of peripheral nerves of the upper limb (e.g., the median nerve) or lower limb (e.g., the posterior tibial nerve), and then recorded from the scalp. The amplitude is the voltage of the electrical stimulation recorded.

  • Latency of the SSEP's [ Time Frame: day of surgery ] [ Designated as safety issue: No ]
    SSEPs (somatosensory evoked potentials) are most commonly elicited by bipolar transcutaneous electrical stimulation applied on the skin over the trajectory of peripheral nerves of the upper limb (e.g., the median nerve) or lower limb (e.g., the posterior tibial nerve), and then recorded from the scalp. Latency is the time interval between the stimulation and response.
