During an operation, surgeons often employ various activities such as intraoperative monitoring (IOM) to achieve the ideal goal of saving lives. However, in cases related to the nervous system an IOM subdivision process called Neuromonitoring or Electrophysiologic monitoring is often employed.
It provides a monitoring purpose that notifies the anesthesia specialist and operating neurologist of an approaching injury so that they can adjust the course of treatment in time to avoid irreversible harm.
This is sometimes used to create and locate neuron regions to help provide technical management. It is a strategy that is employed to reduce possible risks associated with the neural network.
Continue reading as this article provides you with information about the meaning of intraoperative neuromonitoring (IONM), its basics, clinical application, and its technical future directions.
What’s Intraoperative Neuromonitoring?
One of the medical procedures that entails constant checks of brain and neuronal activities during neural operations is known as intraoperative neuromonitoring (IONM). This procedure aids in the structural presentation of the sensorium and also illustrates its likely associated impairments.
Its main objective is to maintain the neurological system’s ideal nature, most especially the central nervous system (CNS) and the peripheral nerve. In addition, IONM provides neurophysiological data, which presents safer and more comprehensive processes that can be executed by the neurologist.
Basics of Neuromonitoring: What you need to know?
In many medical procedures, neuromonitoring has become the standard and has taken the place of intraoperative wake-up testing in spinal surgery. However, there are no evaluating terms and standards of care as most monitoring teams and surgeons choose their methods. Below are its basics:
Objective: During an operation, neuromonitoring is often used to obtain nerves’ electrical potentials produced by their axons. This is carried out to prevent and identify problems before escalating and to reduce any possible complications.
Methods: there are various methods used for surgical neuromonitoring. These are:
Electromyography (EMG): is used for recording muscular activities.
Electroencephalography (EEG): is utilized for measuring brain activity.
Motor Evoked Potential (MEP): This is often used forevaluating motor pathway function.
Somatosensory Evoked Potentials (SSEP): To track sensory pathways integrity.
Application: Neuromonitoring in surgery is often applied in different ways to a wide range of neurological problems eg. Cranial neurosurgery, interventional radiological procedures, Orthopedic spinal correction, stroke, hypoxic-ischemic injury, meningitis, etc.
Procedure: To measure brain reactions, perfectly placed electrodes are applied to the patient, and baseline values are recorded before the commencement of the surgical operation. Throughout the process, there is always proper evaluation, and a swift reaction is often taken whenever there is a baseline alteration.
Teamwork: There is always a cordial interaction between Neurologists, surgeons, and anesthetic teams to obtain current data about brain activity. With this obtained data, the surgical team needs to discuss possible steps and plans among themselves that will help in direct clinical decision-making.
Continuous Evaluation: As the operation continues, there is always a concurrent check that makes the surgeons quickly identify any possible variation in nerve function to make any necessary corrections.
Cutting-Edge Applications in Neuromonitoring Clinical Settings
With the rapid changes and developments in today’s neuromonitoring technology, significant advances have been made in the medical world. These modern techniques in clinical settings have improved immediate nervous system diagnosis and protection. Here are some conspicuous examples:
Advanced Intraoperative MRI: During surgeries, an intraoperative radiological imaging device provides structural or regional images that aid quick nervous detection by neurologists. These magnetic resonated images facilitate easy access to various modifications in the brain or spinal cord.
Optical Coherence Tomography (OCT): The images of some complex optical regions like the optic nerve, and retina can be obtained at high quality. It has been put to use many times to diagnose and manage diabetes’s effect on the retina in conditions like glaucoma and retinopathy.
High-Resonance Image: The application of neuromonitoring in surgeries provides an exceptional method for surgeons to craft comprehensive preoperative planning. Most of the time, it grants fast access to complications during operations with its additional high-resonating imaging features.
Neural stimulation Technique: It comprises advanced methods that use magnetic or electrical stimulation to modify the neuronal response. Also, this technique is often used to map and protect important brain circuits.
Mechanical Alarming System: This is one of the most important innovative applications of surgical neuromonitoring that improves responsiveness. This system automatically identifies and notifies surgical teams of possible problems with the help of AI algorithms.
Clinical Application of Neuromonitoring in Surgery
The application of surgical neuromonitoring methods involves a wide range of healthcare processes that improve patients’ outcomes. Some of its vital applications in medics are:
Surgeries on the brain: Neuromonitoring helps evaluate and protect vital cranial functions during brain surgeries, reducing the possibility of neurological implications. It is used during brain tumor removal and epileptic surgery.
Spinal Cord Surgery: Intraoperative neuromonitoring plays an exceptional role in countless surgeries related to the spine. Some of these are laminectomy, spinal decompression, and fusion. IONM also acts as a protective medium for the spine to evaluate nerve fibers during surgeries.
Musculoskeletal surgery: In conditions related to the skeletal system (joint, suture, or skull) the use of neuromonitoring in surgery is of great significance. Some orthopedic surgeries like laminectomy and kyphoplasty are special operations where electrophysiology monitoring methods can be employed.
Complicated Pediatric Operations: The nervous system in children with complicated medical conditions such as scoliosis and spinal tumors, is monitored to avoid neuronal growth retardation.
Otolaryngological Operations: Intraoperative neuromonitoring helps maintain important neural structures during head and neck surgeries, such as the removal of an auditory neuroma or treatments involving the seventh cranial nerve.
Future Directions in Neuromonitoring Technology
In recent years, there have been countless growth and advancements in the use of surgical neuromonitoringtechnology. However, It is believed that technically neuromonitoring in surgery will progress in several important areas in the future. Such as:
AI Integration: Neuromonitoring devices may improve immediate data processing by using AI algorithms. This might lead to quicker and more accurate neurological signal clarifications, which would help surgeons make instant critical decisions.
Multifunctional Technique: A more enhanced view can be achieved via the combination of different IONM methods. A technique that encompasses an all-in-one (coupling of EMG, EEG, MEP, and SSEP) neuromonitoring in surgery will serve a great function for surgeons.
Digital Assessment and Telesurgery: A more technologically developed neuromonitoring can create a telesurgical approach whereby non-physical surgeons will have the opportunity to operate.
Mobile Access: In the future, the use of wireless surgical neuromonitoring devices can be invented creating an effective medium for tracking the medical progress of a patient. This can also result in easy integration of surgical equipment, enhancing a more versatile operative room.
Neuromonitoring technological advancements have transformed surgical procedures in clinical settings by providing immediate evaluation and nervous system protection. By improving patient outcomes, these advancements mark the beginning of an inventive age in neurosurgery and spine therapies.
