Primary Aim: To determine if there is an optimal scanning technique for ultrasound-guided perineural catheter insertion that will result in the most accurate tip placement in proximity to the target nerve or plexus.
Secondary Aim: To determine if there is an optimal location for ultrasound-guided perineural catheter insertion along a target nerve or plexus that will result in maximum local anesthetic infusion benefits.
