Spinal3
Recordings of SEPs to stimulation of the ulnar nerves at the wrists are useful for intraoperative monitoring when the mid-cervical spinal cord or parts of the brachial plexus are at risk. (medscape.com)
Ulnar nerve SEPs are preferred to median nerve SEPs for assessing the lower cervical spinal cord, especially during intraoperative monitoring when this part of the spinal cord is at risk, because the ulnar nerve originates from spinal roots C8-T1, whereas the median nerve originates from C6-T1. (medscape.com)
These systems are also adaptable for other types of surgical monitoring (i.e., spinal surgery) by creating appropriate software templates. (evokedpotential.com)
Clinical2
SEPs are used for clinical diagnosis in patients with neurologic diseases, to evaluate patients with sensory sympotoms that might be psychogenic, for prognostication in comatose patients, and for intraoperative monitoring during surgeries that place parts of the somatosensory pathways at risk.

Head1
Ultrasonography may be supplemented with CT scanning and/or MRI of the head to monitor for compression of the foramen magnum. (medscape.com)
Electrical1
The equipment should include an isolated electrical stimulator that can be precisely controlled at low levels, differential amplifiers of a good quality, filters to reduce noise, a multichannel oscilloscope to dis- play the signal (at least four-channel), an audio monitor, and the ability to permanently store and printout data.
