Anterior quadratus lumborum block at the lateral supra-arcuate ligament versus thoracic paravertebral block for postoperative analgesia after laparoscopic nephrectomy: a randomized non-inferiority trial.

ABSTRACT:

Background

This study compared the analgesic effects of the anterior quadratus lumborum block at the lateral supra-arcuate ligament (QLB-LSAL) and thoracic paravertebral block (TPVB) for laparoscopic nephrectomy to verify whether the new quadratus lumborum block is an efficient technique for managing laparoscopic nephrectomy pain as an alternative to TPVB.

Methods

This study was a prospective randomized noninferiority clinical trial. Before general anaesthesia, 80 participating patients were randomly allocated to receive QLB-LSAL (20 mL of 0.5% ropivacaine) or TPVB (20 mL of 0.5% ropivacaine). The primary outcome was the mean visual analogue scale (VAS) score in the first 24-hafter surgery. The secondary outcomes included the cutaneous sensory block area, intraoperative haem
