简要总结
The investigators propose to test the hypothesis that when placing a perineural catheter for a continuous peripheral nerve block, injecting the initial local anesthetic bolus via the insertion needle results in a faster-onset sensory block than injecting the initial bolus via the perineural catheter. The study results will help define the optimal local anesthetic bolus introduction technique-needle versus catheter-for peripheral nerve blocks when placing a perineural catheter.

结局指标
主要结局
Sensory Level
时间窗: 120 minutes
EKG pads will be positioned in the 5 major nerve distributions distal to the elbow, ensuring placement is equivalent bilaterally. The primary endpoint will be the time, in minutes, until all 5 nerve territories record \> 60 mA, or 120 minutes-whichever occurs first-since 60 mA is estimated to be equivalent to a surgical incision.
次要结局
- Grip Strength(120 Minutes)
- Sensory level for individual nerves(120 Minutes)
