What is IONM?
Intraoperative Neuromonitoring (IONM) is the evaluation of your neural function during your surgical procedure.
The purpose of IONM is to protect your nervous system. The real-time information of IONM helps prevent neurological injury (damage to the brain, spinal cord, or nerves). Incase neurological injury does occur, the real-time feedback from IONM allows your surgical team to quickly respond to minimize long-term post-operative damage. IONM provides an additional layer of safety for both you and your surgeon.
Nerve signal changes are monitored and immediately reported by a trained IONM technologist using computerized equipment, allowing your surgeon to incorporate this information into his or her surgical decision-making process.
Why has your surgeon recommended IONM?
- Identification of important neural structures in the operative field during your surgery
- Detection of signal deviation allowing the surgeon to avoid damage to neurological function
- Modification of procedure or surgical pathway to avoid/reduce neurological damage
- Monitor recovery of pre-existing or peri-surgical neurological abnormalities
- Improved safety in surgical procedures
Surgical Procedure is the manual or instrumented physical intervention of body structure to treat a disease condition or injury.
The development of advanced surgical techniques and surgical tools have over time transformed surgery from a risky “art” into a scientific discipline capable of treating many diseases and conditions.
Intraoperative Neuromonitoring is one of the latest surgical tools which has become a standard of care for improved safety and surgical outcomes in surgeries involving neural structures.

On the day of your surgery
- Based on your medical history and your pre-op neurological functioning and motor strength the surgical team decides the modality and guidelines that need to be followed for IONM during the surgical procedure and you are accordingly prepared for the IONM process
- You do not need any special preparations for use of IONM during your surgery.
- After you are asleep under anesthesia, special needle sensors will be placed on your body which continuously provide signals to the computerized IONM system displaying relevant information to the IONM technologist.
- The IONM technologist interprets any deviations in signal and provides instant feedback to the surgical team to make appropriate decisions for a safer surgical procedure.
- On completion of surgery, all the needle sensors are removed.
Ask Your Doctor About Neuromonitoring
- IONM is provided at the request of your surgeon as an additional safety measure
- IONM provides reliable real time information on your neural function during complex surgeries involving neural tissue.
- Your surgeon will decide use of IONM based on the procedure planned for your condition.
- Please consult your doctor for any information on and benefits from IONM during your surgical procedure.
