Is FDA regulated | No |
Health authority | United States: Institutional Review Board |
Study type | Interventional |
The primary objective of this prospective, descriptive study is to evaluate the success rate of the retroclavicular brachial plexus block and catheter placement in 60 adult patients undergoing hand, wrist, or forearm surgery. The investigators will also evaluate any difficulties performing the procedure, the onset time and distribution of the block, incidence of adverse events, and patient's acceptance of the block.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Success Rate | Success rate will be defined as the number of patients with anesthesia or analgesia in all five nerves below the elbow (median, ulnar, radial, musculocutaneous, median nerve of the forearm). | 20 minutes after nerve block completed | No |
Secondary | Motor Function | Strength of muscles innervated by radial, median, ulnar, musculocutaneous, and axillary nerves | 20 minutes after nerve block completed | No |
Secondary | Complication of Procedure | Pneumothorax, Horner's syndrome, Symptomatic phrenic nerve palsy, Local anesthesia toxicity, block failure, catheter dislodgement. | From nerve block completion to patient's arrival in PACU, with an expected average duration of 3 hours | Yes |
Secondary | Followup of Block Resolution | Pain/Bruising/Infection at injection site, Unresolved paresthesias/weakness of operative arm, Preferences for Future Surgery | 48-96 hours post Retroclavicular Brachial Plexus Block | No |
