Impact Statement: Ultrasound-guided Brachial Plexus Nerve Blocks (BPNBs) using Ropivacaine and Dexmedetomidine have been proven to shorten the block’s onset, prolong the duration of action, and enhance the analgesic efficacy.

Background: Ultrasound-guided Brachial Plexus Nerve Blocks (BPNB) are commonly used as an alternative to general anesthesia. Research suggests that adding Dexmedetomidine 1mcg/kg to 15ml of 0.5% ropivacaine shortens the onset and prolongs the duration of the block.

Methods: A concise search strategy was implemented to identify suitable studies using Cumulative Index to Nursing and Allied Health (CINAHL) and PUBMED. Eleven articles remained, of which 6 studies met all the specifics of the literature review objectives. A virtual educational module was delivered to Florida International University’s alumni CRNAs, along with a pre and post survey to evaluate gained knowledge.

Results: Of the 8 total participants (N = 8), 50% (n = 4) demonstrated gained knowledge, 25% (n = 2) had no change, and 25% (n = 2) exhibited a decrease in understanding. The results are neither favorable nor unfavorable. Discussion: There was a significant improvement on the likelihood of considering perineural dexmedetomidine. The small sample size, the project’s cybernetic dependence, and the virtual aspect of delivery were limitations of this project.

Conclusion: Considering the ambiguity of the results and the project’s limitations, it is recommended that further research is conducted to educate, guide, and possibly alter current practice standards.
