Brain activity and sedation during anesthesia

This early-stage study checks how brain activity changes when the median nerve is gently stimulated while you’re under general anesthesia with propofol. It may help researchers better understand brain–nerve connections and improve how these signals are measured.

This study looks at how your brain waves change during general anesthesia. It might help doctors understand the best way to keep you safely asleep during surgery.

This trial compares two ways of giving sedation (sleepy medicine) during a procedure to restore normal heart rhythm in people with atrial fibrillation. One method uses a special brain monitor to guide sedation doses, while the other uses standard clinical judgment. The goal is to see if the brain monitor helps keep you safer and more comfortable.

This study uses brain scans (fMRI) to see if people who are lightly sedated can still think or respond. Researchers want to understand 'covert consciousness' during sedation with two common medicines, dexmedetomidine and ketamine.

This study tests a new bedside monitoring system that tracks brain activity in ICU patients who are on a breathing machine and receiving sedative medications. It aims to help doctors better manage sedation and improve patient care.

This study uses focused ultrasound to stimulate a deep brain region and see if it can help people wake up faster from anesthesia. Healthy volunteers will be sedated and monitored while the ultrasound is applied.
