About this study

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time Until First Pain Medication Post-operatively

Secondary outcomes (1)
  1. Pain Score on Post Operative Day 1

    pain score on post operative day 1 was measured on a scale 1-10. higher scores correlates with more severe pain. score range is from '0' (no pain) to 10 (pain as severe as it can be)

    Measured: 1 day postoperative
