A volunteer study to determine the anatomical distribution of injectate, the extent of sensory block, and the pharmacokinetics of ropivacaine following Erector Spinae Plane (ESP) blocks.
This study will recruit healthy volunteers to determine the effect of a peripheral nerve block. The participants will get an injection in their back muscle after an intravenous line is placed in their hand or arm. After the injection they will have two MRI done at 30 and 90 minute time intervals. A half tablespoon of blood also will be taken through the IV line already placed 6 times during the study period starting just before to Peripheral nerve block placement up to four hours post injections. They will be discharged from the study after half an hour of the last blood sample. During this whole process they will be monitored for their blood pressure, oxygen saturation and other effects related to the procedure.
