NIRS is used to monitor cerebral oxygenation and assess cerebral function during surgeries involving the aortic arch.
TIVA is preferred as it has less impact on neurophysiological signals compared to inhalational anesthetics.
Baseline recordings are taken before any surgical intervention to provide a reference for detecting changes during surgery.
EEG is critical for assessing the functional integrity of the cortex by monitoring electrical activity in the brain.
A significant drop in SSEPs can indicate potential ischemic injury to the neural pathways being monitored.
The type of anesthesia can significantly influence the quality of neurophysiological monitoring signals.
NIOM during vascular surgeries aims to continuously monitor the integrity of neural pathways to prevent ischemic damage.
SSEPs are used to monitor the integrity of the spinal cord during AAA repair to detect potential ischemic injury.
A sudden loss of MEPs could indicate potential neural injury, requiring immediate attention from the surgical team.
Continuous EEG monitoring helps detect changes in cortical activity that may indicate ischemia or other complications.
TCD ultrasonography is used to monitor blood flow velocities in cerebral arteries, helping to assess cerebral perfusion.
