Supraclavicular Versus Combined Block for Ulnar and Median Distribution Hand Surgery

NCT01625208 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

No results posted yet for this study

Summary

This study will examine how successfully nerves are blocked or frozen for hand surgery. Traditionally, the nerves are frozen at the base of the neck, just above the clavicle or collarbone (the supraclavicular block). This is mostly successful by itself, and provides anesthesia of the entire arm. Occasionally, an additional nerve block is required further down the arm, as the supraclavicular block may have missed a segment, or it is taking too long to come on. In this study the investigators will compare the traditional technique, with a similar but lower volume supraclavicular block plus an immediate low volume block of one nerve further down the arm (the ulnar or median nerve block, depending on which digits are being operated on). The investigators will compare success rates, speed of onset, procedural comfort and length of time of weakness and numbness, plus any adverse events.
