To help determine if there is improved pain relief when a device that makes an arm muscle move (nerve stimulator) is used to place a needle in the area above the collarbone to prevent feeling of pain (anesthesia) of the upper arm.


The Investigators will use the assessment of onset of motor and sensory block Q 5 minutes to distinguish the difference between blocks performed with ultrasound guidance with or without a nerve blockade monitor.
