Intraoperative neurophysiological monitoring
Intraoperative Neurophysiological Monitoring
Intraoperative neurophysiological monitoring (IONM) or intraoperative monitoring is a technique used during surgery to monitor the functional integrity of certain neural structures (e.g., nerves, spinal cord and parts of the brain) to reduce the risk of damage.
Pronunciation
Intraoperative: /ˌɪntrəˈɒpərətɪv/ Neurophysiological: /ˌnjʊərəʊˌfɪziˈɒlədʒɪkəl/ Monitoring: /ˈmɒnɪtərɪŋ/
Etymology
The term is derived from the Latin intra meaning "within", operativus meaning "working", and the Greek neuro meaning "nerve", physio meaning "nature", and logia meaning "study of".
Description
IONM is used to provide real-time feedback to the surgeon about the patient's neurological status during surgery. This can help to prevent damage to the nervous system, which could lead to complications such as paralysis, hearing loss, or other serious consequences.
Techniques
There are several techniques used in IONM, including EEG, EMG, EPs, and others. The choice of technique depends on the type of surgery and the specific neural structures at risk.
