Ultrasound Guided Local Anesthetic Block: Thoracolumbar Interfascial Plane

"All participants will have two injections at the same vertebral level on each side of the back. Each injection will consist of four 5cc incremental injections with aspiration prior to each 5cc of injectate of 0.5% Ropivicaine. . Each side of the back will be injected with 20cc of .05% Ropivicaine. Ultrasound will be used in real time to guide the needle.~1. Ultrasound images will be saved using the nomenclature TLIP Anatomy~2. Photos will only include surface anatomy of the low-to-mid back.~3. Participants will be assessed for evidence of adverse reaction to local anesthesia (tinnitus, disorientation, or perioral numbness) with each 5cc dose of local anesthetic. If any adverse reactions are noted the dosing will be stopped."
