The goal of this clinical trial is to learn if smart pill bottles can be used as a tool to optimize data collection in clinical trials by increasing the quality of data collected and limiting the associated cost. The main questions it aims to answer are:
Is the use of smart pill bottles a feasible method of data collection in clinical trials in terms of patient adherence.
Is the data collected by the smart pill bottles of higher quality than that collected through human resources? What is the impact of the use of smart pill bottles on the costs involved in clinical trials ?
Researchers will collect data on postoperative opioid medication consumption with the smart pill bottle and assess the adherence of patients to the device along with the quality of data collected and the costs involved in the process.
Participants will:
Use the smart pill bottle to consume opioid medication following surgery for 3 months At the end of the 3 month period, the group will have filled out surveys detailing their opioid consumption, surgical pain and other relevant information.

Glucagon-like peptide-1 agonists (GLP-1RA) are a family of medications used for diabetes and weight loss. One of their effect is to slow down stomach emptying. The goal of this study is to evaluate the effect of GLP-1RA on the effectiveness of fasting before a scheduled surgery.
The question it aims to answer is: does this kind of medication increase the risk of having food or too much liquid in the stomach before a scheduled surgery, even if the minimum 6 hour fast is done?
For this project, researchers will use gastric ultrasound to compare participants already taking one of these medications as part of their home treatment to participants who are not taking them. Gastric ultrasound is a simple bedside exam using an echography machine that takes less than 5 minutes to do.
Participants will:
-Have a gastric ultrasound performed on them before their surgery

The goal of this observational study is to explore the variability of the concentration at the effect site (Ce) of propofol to reach deep anesthesia (DA) during induction of general anesthesia in adults.
The investigators hypothesized that there is a great variability in this Ce that could be precisely explained by
* Electroencephalographic (EEG) features available prior to induction of anesthesia
* Cognitive performance
* Patients characteristics Participants will undergo preoperative cognitive testing and awake EEG. Then, induction of general anesthesia will be performed using continuous infusion of propofol. The Ce at which Deep anesthesia is observed will be recorded.
