Minimum effective volume of lidocaine for double-injection ultrasound-guided axillary block.
The aim of this study was to determine the minimum effective volume of lidocaine 1.5% with epinephrine 5 μg/mL in 90% of patients (MEV90) for double-injection ultrasound-guided axillary block (AXB). ⋯ For double-injection ultrasound-guided AXB, the MEV90 of lidocaine 1.5% with epinephrine 5 μg/mL is 5.5 and 23.5 mL for the musculocutaneous nerve and perivascular injection, respectively. Further dose-finding studies are required for other concentrations of lidocaine, other local anesthetic agents, and other techniques for ultrasound-guided AXB.

Outcomes of shoulder surgery in the sitting position with interscalene nerve block: a single-center series.
Several case reports have raised serious concerns about the safety of shoulder surgery in the beach-chair position, related to global cerebral hypoperfusion. We summarize our experiences with 15,014 cases of shoulder arthroscopy over an 11-year period. Our primary aim was to evaluate the incidence of intraoperative or immediate postoperative neurologic events and secondarily to relate other perioperative complications. ⋯ This retrospective study suggests that intraoperative or immediate postoperative stroke is rare when surgery is conducted in beach-chair position in conjunction with regional anesthesia, propofol sedation, and spontaneous respiration via natural airway.
