Intraoperative Neurophysiological Monitoring

Abstract

In the early days of intraoperative monitoring, either custom-made equipment or equipment taken from the clinical testing laboratory of the neurophysiological animal laboratories was used in the operating room. Now, there is specialized equipment commercially available for nearly all needs of intraoperative monitoring. This means that the persons who perform monitoring and intraoperative neurophysiology do not need to know as much about recording and stimulating equipment as they once did. However, knowledge about the basic function of the equipment that is used for intraoperative monitoring enables optimal use of the equipment and is important for troubleshooting. The equipment now commonly utilized for intraoperative neurophysiology is capable of appropriate signal processing, has several ways of filtering the recorded responses, and has many options for displaying the potentials recorded. The user must have sufficient knowledge, however, about the basis for filtering and signal averaging to use these methods in optimal ways.

Notes

  1. 1.

    The decibel scale is a logarithmic measure of ratios, such as the ratio between the amplitude of the output and that of the input; thus, it is a measure of attenuation or amplification. For voltage ratios, it is defined as 20 log10 E o/E i, where E i is the input voltage and E o is the output voltage, an attenuation of 3 dB means that the output is 0.707 times the input, a 6 dB attenuation means that the output voltage is half of the input, a 10 dB attenuation means that the output is 0.3 of the input, a 20 dB attenuation means that the output is 0.1 of the input, and so on.
