Review Meta AnalysisAlpha2 -receptor agonists as adjuvants for brachial plexus nerve blocks - a systematic review with meta-analyses.
We review the efficacy and safety of dexmedetomidine and clonidine as perineural or systemic adjuvants for brachial plexus blocks (BPB). ⋯ Alpha2-receptor agonists used as adjuvants for BPBs lead to a prolonged duration of analgesia, with dexmedetomidine as the most efficient. Alpha2-receptor agonists were associated with increased risk of cardiovascular adverse events. The quality of evidence was low to very low.

Patients undergoing spine surgery may experience substantial postoperative pain. The aim of this systematic review is to examine the clinical efficacy of a newly introduced regional anesthetic block, the erector spinae plane block (ESPB), for adults undergoing posterior spine surgeries. ⋯ Current evidence is insufficient to support the widespread use of ESPB for spine surgery. More studies are warranted to confirm or refute its role in clinical practice.
