Effects of Desflurane-propofol Balanced Anesthesia on Visual Evoked Potentials Monitoring
China70 participantsStarted 2022-07-20
Plain-language 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.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
