Comparison of analgesic efficacy of pericapsular group of nerve block versus anterior quadratus lumborum block in adult patients undergoing unilateral hip arthroplasty: A comparative randomized controlled trial
Authors' conclusion
There was no difference in the perioperative opioid consumption, pain scores, and adverse event rates between the pericapsular nerve group block and anterior quadratus lumborum block in adult patients undergoing unilateral hip arthroplasty.
Study context
- Population
- Adults >18 years undergoing elective unilateral total hip arthroplasty under spinal anesthesia, tertiary care center
- Participants
- 92 adults
- Comparison
- PENG block vs anterior QL block
- Primary endpoint

Primary result
As reported in the abstract
Total fentanyl consumption · 24 h
P = 0.617
Further findings
Time to first rescue analgesia · similar in both groups
P = 0.120
NRS pain scores at rest and on movement (0–24 h)
- No difference in pain scores
Safety
- No difference in intraoperative hemodynamic changes or PONV
