Intraoperative Monitoring

How Intraoperative Monitoring Works

IOM relies on a few coordinated techniques working together throughout a procedure:

• Baseline recording. Before the surgical work begins, the IOM team establishes a baseline reading of nerve function to compare against everything that follows.
• Continuous tracking. Signals are monitored throughout the procedure and checked against that baseline in real time, flagging changes in strength, timing, or pattern before they become a lasting injury.
• Stimulation and response. Specific points along a nerve pathway are stimulated, and the resulting response is recorded to confirm the pathway remains intact, even while the surgeon is actively operating nearby.
• Direct communication with the surgeon. Findings are relayed to the surgical team as they happen, allowing real-time decisions informed by direct neurological feedback rather than visual assessment alone.

IOM works best as a continuous conversation between the monitoring team and the surgeon rather than a passive recording tool running in the background.

Experience Extra Protection With IOM

For procedures involving the brain, spine, spinal cord, or peripheral nerves, even small and unintended changes in pressure or position can affect nerve function. Intraoperative monitoring gives GNI’s surgical team an additional layer of protection against post-operative complications by providing continuous, objective information about nervous system function throughout the case.

This technology reflects the same philosophy that runs through every aspect of care at Georgia Neurosurgical Institute: the more information a surgical team has access to in real time, the better equipped they are to protect the patient. IOM is one of several tools, alongside robotic guidance and advanced imaging, that GNI’s surgeons use to bring an added measure of precision and safety to complex procedures.
