Some Common Problems and Pitfalls in Intraoperative Monitoring of Evoked Potentials
This chapter reviews and suggests remedies for some of the common problems and pitfalls that may be encountered when sensory evoked potentials are recorded in the operating room to monitor the auditory and somatosensory system, and when electromyographic potentials are recorded intraoperatively for monitoring of cranial motor nerves.
In a new discipline such as that encompassing the use of evoked potentials in intraoperative monitoring, problems and pitfalls are many. Therefore this chapter naturally cannot provide complete coverage of what can go wrong in the operating room and how recordings can be misinterpreted, but it must instead focus on a small sample of the problems that can be encountered by the neurophysiologist performing intraoperative monitoring of evoked potentials.
