Comparison of Central Versus Peripheral Placement of Local Anesthetic

Not Applicable

Completed

• Conditions: Hand Surgery; Forearm Surgery; Elbow Surgery; Wrist Surgery
• Interventions: Procedure: Peripheral placement of local anesthesia; Procedure: Central placement of local anesthesia

• Registration Number: NCT00699244
• Lead Sponsor: Vanderbilt University

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.
