In Brief

A Phase 4 clinical trial evaluating Ropivacaine and Epinephrine for Distribution of Ropivacaine in Erector Spinae Plane Block. Completed, enrolled 12 participants across 1 site.

Detailed Summary

The primary objectives of this study are to define the extent of dermatomal anesthesia and anatomical spread of injectate (as defined by MRI imaging) that is provided by an ESP block at the T5 level, using twenty milliliters of 0.5% ropivacaine. The secondary objectives include: 1) the measurement of changes in hemodynamic parameters associated with the ESP block, 2) the duration of sensory effects provided by ropivacaine with or without epinephrine, 3) the venous plasma concentration of ropivacaine associated at various time intervals after completion of the ESP block.
