Randomized Controlled Trial
Effects of quadratus lumborum block regional anesthesia on postoperative pain after colorectal resection: a randomized controlled trial.
Postoperative pain following colorectal surgery is associated with a significant use of opioids. Recently, regional anesthesia, such as the posterior quadratus lumborum block (QL2), has been proposed to improve pain relief and reduce opioid use. However, the benefit of the QL2 on postoperative pain control remains controversial. ⋯ We did not observe a reduction in postoperative opioid administration at 24 h with a posterior quadratus lumborum block regional anesthesia in patients undergoing elective colorectal surgery.

Randomized Controlled Trial
Transverse vs. parasagittal in-plane approaches in ultrasound-guided paravertebral block using a microconvex probe: A randomised controlled trial.
Several approaches have been proposed for ultrasound-guided thoracic paravertebral block, but the best approach remains unclear. ⋯ There were no clinically significant differences between approaches for continuous ultrasound-guided thoracic paravertebral block using a microconvex probe, and both approaches achieved a high rate of correct catheter placement.

Randomized Controlled Trial
Prospective Single-Blinded Randomized Controlled Trial Comparing Pericapsular Injection Versus Lumbar Plexus Peripheral Nerve Block for Hip Arthroscopy.
Hip arthroscopy has become the standard for the operative treatment of symptomatic femoroacetabular impingement. Given the high levels of postoperative pain associated with hip arthroscopy, optimal analgesia is critical to ensure patient comfort and safety after discharge. ⋯ ClinicalTrials.gov ID: NCT03244631.
