Patient Positioning and Its Influence on BIS, NOL, and Cerebral Oxygenation in Anesthetized Patients
64 participantsStarted 2025-08
Plain-language summary
The goal of this observational study is to find out how changes in body position during surgery might affect brain monitoring results in patients who are under general anesthesia.The main question it aims to answer is:
\- Does patient positioning have an impact on Bispectral Index (BIS) and Nociception Level (NOL) index monitoring (which are values of awareness in anesthesized patients).
Participants will undergo their surgery as planned, except for these extra features:
* Extra monitors placed to check brain activity, pain response, and brain oxygen levels.
* Before the surgery, while the patient is asleep, the patient's table will be moved into two different positions for 2 minutes each to see if the values on the monitor change.
Participants will then have to answer a short questionnaire after surgery about their memories before and after the anesthesia.

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?

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?
