This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This research study is investigating how blood pressure levels during general anesthesia affect blood flow to your brain. Researchers will use special MRI imaging to measure brain blood flow while your blood pressure is adjusted during your planned surgery. The goal is to understand what blood pressure targets work best to protect your brain during anesthesia.
During surgery under anesthesia, it's important to maintain enough blood flow to the brain to prevent confusion and cognitive problems after surgery. Currently, doctors use general blood pressure targets that may not be ideal for every patient. This study aims to find better, personalized blood pressure targets that protect brain function during surgery.

You will undergo your planned surgery as scheduled under general anesthesia. During your surgery, researchers will use special MRI imaging (a non-invasive scanning technique) to measure blood flow in your brain while your anesthesia team carefully adjusts your blood pressure. The study involves one MRI session during your surgical procedure, with no additional visits or follow-up appointments required beyond your normal surgical care.
