Duration of Analgesic Effect for Ultrasound Guided Supraclavicular Blocks With the Addition of Buprenorphine to Local Anesthetic Solution

Stopped early · Not applicable

Conditions studied: Regional Block for Pain Control, Supraclavicular Block, Ultrasound Guided Block, Block Additive

In brief

The patients included will be those who have already agreed to have a brachial plexus nerve block for surgery. A flip of the coin will decide who gets and additive called buprenorphine in their block or not. They will both contain the same amount and type of numbing medicine. The goal will be to see if the additive extends the life of the pain control portion of the ultrasound guided supraclavicular nerve block.
