Brief summary

Does ultrasound increases the success rate and if there is a difference in success rate between placing the local anesthetic centrally versus peripherally.

Detailed description

A comparison of the infraclavicular placement of local anesthetic either centrally (posterior cord) vs peripheral placement (lateral or medial cord) using ultrasound guidance. This will be done to determine if ultrasound increases the success rate and if there is a difference in success rate between placing the local anesthetic centrally versus peripherally.
