“…Changes in evoked responses can result from technical, positional, pharmacologic, physiologic, or surgical causes. 2,10 Morphology of the recorded waveform depends both on the site used for stimulation and the site used for recording. The amplitude and latency of the waveform can be analysed to provide functional neurologic assessment.…”

“…Loss of or change in the waveform can indicate the need for modification of surgical strategy, patient positioning, and/or patient physiologic management in order to prevent or minimise neurologic system injury. 7,10 Somatosensory evoked potentials SSEP is the most commonly used evoked potential monitoring modality in the operating room. An electrical stimulus is applied to a peripheral nerve, typically median or ulnar nerve and posterior tibial nerve for upper and lower limbs respectively to elicit a response.…”

Neuromonitoring is used during surgery to assess the functional integrity of the brain, brain stem, spinal cord, or peripheral nerves. The aim of monitoring is to prevent permanent damage by early intervention when changes are detected in the monitor. Neuromonitoring is also used to map areas of the nervous system in order to guide management in some cases. The best neuromonitor remains the awake patient. In the conscious state, the function of individual parts of the nervous system and the complex interactions of its different parts can be assessed more accurately. However, most surgical procedures involving the nervous system require general anaesthesia. Procedures that require neuromonitoring can have changes in their monitored parameters corrected by modifying the surgical approach or by having the anaesthesiologist manipulate the parameters under their control. An ideal neuromonitor would be one that is specific for the parameter of interest, and gives reliable, reproducible, or continuous results.
