Randomized Controlled TrialTransmuscular quadratus lumborum block reduces opioid consumption and prolongs time to first opioid demand after laparoscopic nephrectomy.
Robotic and hand-assisted laparoscopic nephrectomies are often associated with moderate to severe postoperative pain. The aim of the current study was to investigate the analgesic efficacy of the transmuscular quadratus lumborum (TQL) block for patients undergoing robotic or hand-assisted laparoscopic nephrectomy. ⋯ Preoperative bilateral TQL block significantly reduced postoperative opioid consumption by 43% and significantly prolonged time to first opioid.

American Society of Regional Anesthesia and Pain Medicine Local Anesthetic Systemic Toxicity checklist: 2020 version.
The American Society of Regional Anesthesia and Pain Medicine (ASRA) periodically updates its practice advisories and associated cognitive aids. The 2020 version of the ASRA Local Anesthetic Systemic Toxicity checklist was created in response to user feedback, simulation studies and advances in medical knowledge. This report presents the 2020 version and discusses the rationale for its update.

Evaluating the spread of costoclavicular brachial plexus block: an anatomical study.
The costoclavicular brachial plexus block is performed deep and posterior to the midpoint of the clavicle. There are limited data evaluating the spread of the costoclavicular brachial plexus block. We performed a cadaveric study to evaluate the spread of injectate after a costoclavicular brachial plexus block. ⋯ This cadaveric study demonstrates that ultrasound-guided injection in the costoclavicular space spreads cephalad to the brachial plexus in the supraclavicular space, consistently reaching the suprascapular nerve and all trunks and cords of the brachial plexus, while sparing the phrenic nerve.
