Physicians and Hospitals

Intraoperative neurophysiological monitoring (IONM) is designed to warn the surgeon of a problem within the nervous system before it leads to permanent neurological injury. The use of IONM can reduce hospital stay time, allow a faster recovery, and reduce the potential for corrective procedures.

During surgery, IONM uses a variety of electro-physiological monitoring procedures to allow for early warning and the avoidance of injury to the nervous system structures.  IONM allows surgeons and hospitals to offer their patients peace of mind, and show that they are doing everything in their power to produce the best outcome possible for that patient. 

 

Our neurophysiologists are located in the operating room throughout the entire surgery.  They attach electrodes to the patient that monitor important nervous structures.  Our neurophysiologists work as a team with a supervising board certified neurologist who oversees the interpretation of the data gathered during surgery via a real-time, remote connection. 

Types of Surgery

IONM can be used to protect patients in a variety of settings.  Our technologists are trained to monitor:

  • Neurosurgery

  • Orthopedic Surgery

  • ENT/Otolaryngological Surgery

  • Vascular Surgery

  • Cardiothoracic Surgery

 

Modalities

Our neurophysiologists are trained to run the following modalities to ensure patients safety throughout the surgery. Our neurologist/neurophysiologist team recommends which modalities should be run while performing a surgery, but our surgeons are the ultimate decision makers, and can choose to run any modalities they deem necessary. Our technologists offer the following modalities:

   

  • Somatosensory Evoked Potentials (SSEP)

  • Electromyography (EMG), including Pedicle Screw and Direct Nerve Testing

  • Electroencephalography (EEG)

  • Motor Evoked Potentials (MEP)

  • Cranial Nerve EMG, including Facial Nerve Monitoring for ENT Procedures

  • Peripheral Nerve Conduction

  • Transcranial Motor Evoked Potentials (TcMEP)

  • Auditory Brainstem Response (ABR)

  • Phase Reversal

  • Cortical Mapping

  • Lateral Spread


Equipment
We take into consideration the needs of our hospitals and surgeons, and provide our neurophysiologists with the high quality equipment that surgeons prefer. When a certain machine is required for a specific surgery, our team ensures that the machine is present in the OR. Currently, we use the following systems:

 

  • Cadwell Cascade 16 Channel

  • Cadwell Cascade Elite

  • Medtronic NIMS 3.0
