Summary

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.

Who is the study for?
This trial is for individuals with Complex Regional Pain Syndrome who need nerve blocks for surgery or pain management. Specific eligibility criteria are not provided, so it's important to contact the study organizers for detailed requirements.
What is being tested?
The study tests if using the B Braun HNS 12 nerve stimulator improves the quality of nerve blocks compared to a sham (fake) control. It aims to determine whether electrical stimulation does more than just help find the right nerve during block placement.
What are the potential side effects?
Potential side effects are not explicitly mentioned but may include discomfort from electrical stimulation and risks typically associated with peripheral nerve blocks such as infection, bleeding, or nerve damage.

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: Ultrasound-guided brachial plexus block with peripheral nerve stimulationExperimental Treatment1 Intervention
Patients will receive a single shot brachial plexus block with ultrasound guidance as per standard of care, with additional use of the B. Braun HNS 12 nerve stimulator for duration of block placement.
Group II: Ultrasound-guided brachial plexus block without peripheral nerve stimulationPlacebo Group1 Intervention
Patients will receive the single shot brachial plexus block in the same way the first arm would, and the B Braun nerve stimulator will be placed in the same way, but not turned on.
