Axis Neuromonitoring Axis Neuromonitoring

If you are a patient preparing for surgery, you may be wondering about Intraoperative Neuromonitoring.  Intraoperative Neurophysiological Monitoring (IONM) or Intraoperative Monitoring is a technique that is used to reduce the risk of neurological injuries or damage to a patient during surgery which may not be evident until after an operation. IONM records electrical responses from sensors placed on the patient's body and monitors the functional integrity of the body's neural network. The information provided by IONM allows a surgeon to perform a safer and more controlled surgery for the patient.

We’ve prepared some information here for your research into IONM.

What is neuromonitoring?

Your body has its own electrical system. Only instead of fuses and wires, yours is created of neuro pathways with unique neurological responses.

Intraoperative Neuromonitoring (IONM) keeps tabs on how these neuro pathways are reacting to electrical stimulations in real time as the surgeon operates. If the technologist notices a change in response time or strength, the surgeon can be notified and take corrective action.

What is the process?

Electrodes are attached to your body in various places depending on the procedure being performed. A technologist will use these electrodes to send electrical impulses through your body in order to monitor nerve pathways. The speed and intensity of the signals are constantly compared to established standards.

Who uses the information?

Your technologist uses a special computer to read these signals throughout your surgery. In addition, another physician reviews your neural data in real time via telemedicine. If anything changes in your nerve pathways, they can immediately inform the surgeon so the problem can be identified and corrected.

What is telemedicine?

Thanks to the Internet and other information technologies, physicians can now help patients remotely. This is great for patients because it eliminates distance barriers and improves access to medical services. During your surgery, one of our remote physicians monitors the real time data reported from your technologist from an offsite location. This means you have two sets of expert eyes keeping track of your neuro pathways, one right next to you and one in another location.

How do I prepare for neuromonitoring?

Prior to surgery, you’ll discuss your medical history with an Axis technologist. If you have any questions or concerns about our services, share them. Also, remember to mention any special medical conditions you may have, like:

  • Pacemaker
  • Metal implants
  • Seizures
  • Stroke
  • Previous surgeries

The Day of Surgery

To help prepare our patients for their upcoming surgeries, we created this short video.  It illustrates the role AXIS Neuromonitoring plays the day of surgery.
