“…For sep SSC the reproducibility was better than with halothane anaesthesia, which is currently used in the authors' clinic for recording sep . In anaesthetised human beings, balanced anaesthesia with nitrous oxide in oxygen, narcotic infusions and muscle relaxants are used for the recording of somatosensory evoked potentials (Worth and others 1982, Hahn and Latchaw 1983, Brown and others 1984, Pathak and others 1984).…”

Sufentanil and nitrous oxide anaesthesia for the recording of transcranial magnetic motor evoked potentials in dogs

et al. 1996

Transcranial magnetic motor evoked potentials were recorded from the extensor carpi radialis muscle of the forelimbs and from the cranial tibial muscle of the hindlimbs of anaesthetised dogs. The dogs were premedicated with droperidol and fentanyl and a light plane of anaesthesia was induced and maintained with sufentanil and nitrous oxide. The potentials recorded under sufentanil and nitrous oxide anaesthesia were suppressed in comparison with baseline recordings under droperidol and fentanyl sedation: their latencies were significantly increased and their amplitudes significantly decreased (P < 0.05). However, the potentials could be recorded reliably in all the dogs and with very good reproducibility. This narcotic anaesthesia also allowed sensory evoked potentials to be recorded reliably.

“…After cleaning and lightly abrading the areas of contact, gold cup electrodes were prepared with conductive paste, and placed at the scalp at C3' and C4' (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) International System) with Fpz as the reference site. Recording surface electrodes were also placed over C2 (Cervical-2), Erb's point (supraclavicular fossa), and on the medial aspect of the upper arm in the axillary region; reference site for these areas was at the ipsilatera1 tips of the shoulders.…”

The dermatomally stimulated somatosensory evoked potential is an essentially painless, noninvasive procedure that can add useful information to the diagnosis of the site and extent of brachial plexus injuries. In this study, 13 patients with unilateral brachial plexus injuries who had previously undergone conventional electromyographic testing underwent somatosensory evoked potential recording with median, ulnar, radial, musculocutaneous nerve and C5, C6, C7, C8 and T1 dermatomal stimulation. There was no significant difference in the peak latencies, interpeak latencies, or amplitudes of the major peaks between the normal values and the values from the affected levels. However, analysis for absence or presence of major peaks from side-to-side was useful in supporting the data from electromyographic and radiologic studies, as well as in providing more specific information as to the level of injury and extent of injury in two of the cases. The accurate diagnosis can provide the information needed to determine patient treatment as well as plan the rehabilitation program of the patient. The dermatomal somatosensory evoked potential can be a useful supplement to the assessment of the patient with a brachial plexus injury.
