Clinical Trial Summary

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.
