IV Opioids for Postoperative Pain

We hypothesize that patients who receive a supraclavicular block via Angiocath, placed intra-operatively and dosed post-operatively following neurologic examination, will have lower pain scores, lower use of intravenous morphine equivalents in the post-anesthesia care unit, and lower rates of intervention for post-operative nausea and vomiting. We also hypothesize that patients receiving this nerve block had the same rates of nerve damage as the patients who did not receive a block and that there will be no demonstrable safety concerns with this block.
