[Preoperative and Intraoperative Electrophysiological Monitoring During Neurosurgery]

Area of Science:

• Neurosurgery
• Neurology
• Surgical Technology

Background:

• Intraoperative neuromonitoring is essential for enhancing safety during complex neurosurgical procedures.
• Motor-evoked potentials (MEPs) and somatosensory-evoked potentials (SSEPs) are the primary techniques employed.
• Effective neuromonitoring requires careful selection of techniques based on individual patient cases.

Purpose of the Study:

• To provide a comprehensive overview of the practical applications of intraoperative neuromonitoring.
• To classify the different types of motor-evoked potentials (MEPs) used in neurosurgery.
• To highlight the importance of pre-operative communication regarding monitoring strategies and high-risk procedures.

Main Methods:

• Classification of MEPs into transcranial, direct cortical, and subcortical stimulation.
• Description of the selection criteria for MEPs based on surgical case specifics.
• Discussion of common intraoperative troubleshooting scenarios for neuromonitoring.

Main Results:

• MEPs and SSEPs are the most frequently utilized neuromonitoring techniques.
• The choice of MEP stimulation method is highly dependent on the specific neurosurgical case.
• Effective troubleshooting is key to maintaining the integrity of intraoperative monitoring.

Conclusions:

• Intraoperative neuromonitoring, particularly MEPs and SSEPs, significantly contributes to patient safety in neurosurgery.
• A clear understanding of MEP classification and application is vital for surgical teams.
• Proactive communication and case-specific planning are crucial for successful intraoperative neuromonitoring.
