Intraoperative Neuromonitoring (IONM)

As a safeguard to reduce the risk of stroke or paralysis, WakeMed offers a type of monitoring during surgery called intraoperative neuromonitoring. This type of nervous system monitoring is typically done during the following procedures:

  • Spinal surgery/scoliosis or tumors
  • Aneurysms
  • Vascular procedures
  • Acoustic neuroma surgery
  • Carotid endarterectomy
  • ENT surgeries involving facial nerves

Learn what to expect from intraoperative neuromonitoring
During surgery, electrodes are placed on the nerves nearby the surgical site or in some cases on the patient’s wrists, ankles, head and shoulders. As surgery progresses, the nerves are stimulated using a small electric current to test if they are functional. The impulses are transmitted and shown as waves on a screen so that the surgeon can track any changes in nerve function. If the waveforms change, then the surgeon can adjust the procedure to protect from damaging the nerves.

Intraoperative neuromonitoring is performed in the WakeMed’s specialized Neurosurgical Operating Suites and at other WakeMed locations where these procedures are performed.
