Study ID
NCT06566664
Status
Enrolling By Invitation

Conditions

  • Pain Management
  • Pain Syndrome

Eligibility Criteria

ALL
Age
18 Years - N/A

Interventions

  • B Braun HNS 12 nerve stimulator — DEVICE
    Nerve stimulator that is traditionally used for nerve localization during block placements.
  • B Braun HNS 12 nerve stimulator sham control — DEVICE
    Stimulator will be placed and turned on, but the grounding electrode will not be connected to prevent nerve stimulation.

Study Details

Peripheral nerve blocks are routinely used and highly successful for intra-operative anesthesia and post-operative pain management. Nerve blocks are guided using either neurostimulation as a means to localize the right nerve or by ultrasound guidance or combining the 2 methods. The purpose of this study is to assess whether electrical stimulation improves nerve block quality, beyond its simple purpose of nerve localization.

Arms

  • Experimental: Ultrasound-guided brachial plexus block with peripheral nerve stimulation
    Patients will receive a brachial plexus catheter with ultrasound guidance as per standard of care, with additional use of the B. Braun HNS 12 nerve stimulator during the loading dose of local anesthesia to maintain a gentle twitch.
  • Sham Comparator: Ultrasound-guided brachial plexus block without peripheral nerve stimulation
    Patients will receive the brachial plexus catheter in the same way the first arm would, and the B Braun nerve stimulator will be placed in the same way, but the ground electrode will not be connected to the patient.

Primary Outcome Measure

Onset of sensory block [ Time Frame: Within 1 hour after the block placement ]
