Sedation and Pain (The Effect of IV Sedation on Pain Perception)

June 24, 2014 updated by: Michael Froelich, University of Alabama at Birmingham
The investigators propose to evaluate the potential effect of sedation on pain perception in two ways, by asking for a participant's pain rating(subjective) and by evaluating a subject's brain activation using fMRI(objective).

Detailed Description

We propose to contrast and compare the effect of propofol and midazolam, two GABA-related sedative drugs, and dexmedetomidine, an alpha-2 adrenergic agonist, on pain perception in human volunteers by asking a participant to rate their pain and by evaluating a subject's brain activation using fMRI.
