Study Summary
Interventional pain procedures have diagnostic, prognostic and therapeutic value. It is well-documented that the reference standard for identifying a pain generator is a low-volume block performed with local anesthetic, with or without steroid. Many factors may increase the false positive (FP) rate of diagnostic and prognostic nerve blocks; however, the use of sedation is the most controversial and remediable. Proponents of sedation argue that it has little effect on the rate of positive diagnostic blocks, and may even reduce the false-negative rate. The purpose of this study is to determine the effect of intravenous sedation on pain relief and the "false-positive rate" after diagnostic nerve blocks.
Primary Outcome
pain diary using 0-10 scale, with 0 being no pain and 10 being the worst pain imaginable
