Randomized Controlled Trial
Less painful ESWL with ultrasound-guided quadratus lumborum block: a prospective randomized controlled study.
Objectives: Extracorporeal shock wave lithotripsy (ESWL) has been widely used for the treatment of urinary tract stones and is usually administered as an outpatient procedure, although the vast majority of patients do not tolerate it without sedoanalgesia. The quadratus lumborum block (QLB) is a newly-defined technique for abdominal surgery. The aim of this study was to evaluate the analgesic efficacy of ultrasound-guided QLB in ESWL. ⋯ The fragmentation success rate was significantly higher in Group QLB than in Group C (19/20 vs 14/20, respectively, p = 0.046). Patient satisfaction was also higher in Group QLB (p = 0.011). Conclusions: This study shows that QLB provided adequate analgesia for ESWL and that it reduced extra opioid consumption significantly compared to the control group.
