Summary
Intraoperative flash visual evoked potentials (FVEPs) can be used to monitor the integrity of
the visual pathway in real-time during surgeries, and is to prevent the damage and
deterioration of visual function caused by visual pathway damage, which is the key method of
intraoperative monitoring of visual function.
Spinal surgery in the prone position may compress the eyeball and reduce the blood supply of
the ophthalmic artery, which is still one of the main causes of postoperative visual
impairment. Intraoperative FVEPs monitoring is easily affected by inhale anesthetics, and
there is little studies on the effect of intravenous-inhalation balanced anesthesia on FVEPs
monitoring. Desflurane wakes up quickly, which is conducive to the recovery of early
respiratory function and orientation, and early neurological evaluation. This study aims to
compare the effects of desflurane-propofol balanced anesthesia and desflurane pure inhalation
anesthesia on the amplitude and latency of FVEPs during spinal surgery under the same
sedation depth monitored by bispectral index (BIS) monitoring.
