Ultrasonic Deep Brain Stimulation During Anesthetic Sedation

University of Michigan·interventional·Posted Aug 10, 2022·Updated Mar 12, 2025

In Brief

A Phase 2 clinical trial evaluating Low-intensity focused ultrasound pulsation (LIFUP) and Functional Magnetic Resonance Imaging (fMRI) using Propofol for Mental Function. Completed, enrolled 13 participants across 1 site.

Detailed Summary

The purpose of this study is to see if mental functions take place during different levels of anesthesia. The researchers expect to gain a deeper understanding of mental function during different levels of anesthesia, and to evaluate if the use of ultrasonic brain stimulation accelerates return to consciousness.

Interventions

Low-intensity focused ultrasound pulsation (LIFUP)device

LIFUP will be used to stimulate specific brain regions and assess their causal involvement in the control of conscious state and contents.

Functional Magnetic Resonance Imaging (fMRI) using Propofolcombination

Propofol will be administered by intravenous infusion. All anesthesia equipment, supplies, and drugs will be provided by anesthesiologists from the University of Michigan Health System. The researchers will manually control the infusion of propofol to achieve target effect-site concentrations
