Study Overview
Brief Summary
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.
Detailed Description
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.

Outcomes
Primary Outcomes
Dermatomes With Complete Motor Block of the Upper Extremities at 30 Minutes
Time Frame: 30 minutes post block
dermatomes (with full motor block) will be the outcome measure The investigators will be assessing changes between muscle strength in the myotomal distribution of the upper limb corresponding to the dermatome region of the brachial plexus following supraclavicular block, using the MRC power scale (medical research council scale, 0-5), with strength values obtained at time zero (initiation of the block), and to compared to subsequent measurements in 5 minute intervals until the final measurement at 30 minutes following the block.
Secondary Outcomes
No secondary outcomes reported
