Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Local Anesthetic Via Catheter

30mL of Lidocaine (local Anesthetic) will be injected via a perineural catheter at hour 0.

Group Type ACTIVE_COMPARATOR

Local Anesthetic given via perineural catheter for infraclavicular nerve block.

Intervention Type PROCEDURE

Patients will be randomized to receive 30mL of Lidocaine via Catheter for an infraclavicular nerve block on one side (right or left) and via needle on the other side. Sensory and strength will be tested following local anesthetic administration.

Local Anesthetic Via Needle

30mL of Lidocaine (local Anesthetic) will be injected via a needle at hour 0.
