PatientIntraoperative Monitoring
Intraoperative neuromonitoring is an assortment of monitoring tools or techniques that may be used by your surgeon to evaluate the function of your nervous system at various points during your surgery. These tools record brain waves produced in response to several types of stimulation including small electrical pulses applied to the nerves, flashes of light to the eyes and clicks of sound to the ears. Muscles are also monitored for abnormal electrical activity that might suggest injury to the nerve connected to them. Ongoing brain activity can be measured using electroencephalography (EEG). There are no lasting side effects from this monitoring. It does, however, allow your surgeon to assess the integrity of the part of the nervous system that he or she is working on or near to. This, in turn, allows for a quick response to evidence of injury or dysfunction.
