Intraoperative Monitoring
Also written as: IOM — Intraoperative Monitoring
Real-time neurological function assessment during brain tumor surgery to guide safe resection and prevent deficits.
Full Definition
Intraoperative monitoring encompasses various techniques used during brain tumor surgery to assess neurological function in real-time, enabling surgeons to maximize tumor resection while preserving critical brain functions. Methods include motor evoked potentials, somatosensory evoked potentials, direct cortical stimulation, and speech testing during awake procedures. These monitoring techniques provide immediate feedback about the functional status of eloquent brain areas, allowing surgeons to adjust their approach dynamically. Proper documentation includes baseline values, changes during surgery, and final functional assessments.
Usage
Usage note: Document specific monitoring modalities used and any functional changes observed.
