Brief 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 and after 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.
Hard data of the monitors will be extracted and analyzed to evaluate any possible correlation between the position of the patient and brain monitoring results. Participants will then have to answer a short questionnaire after surgery about their memories before and after the anesthesia.
