This prospective randomized controlled trial evaluated the analgesic efficacy of ultrasound-guided erector spinae block (ESPB), thoracic paravertebral block (PVB), and quadratus lumborum block (QLB) in 48 patients undergoing open renal surgeries. All block techniques significantly reduced postoperative pain and opioid consumption compared to systemic analgesia, with QLB showing the greatest opioid-sparing effect (8.0 ± 2.5 mg).
Key findings
- VAS scores were significantly lower in all block groups compared to the control group at all-time points (p < 0.001).
- Total morphine consumption was highest in the control group (25.0 ± 4.5 mg) and lowest in the QLB group (8.0 ± 2.5 mg) (p < 0.001).
- Patient satisfaction was significantly higher in the block groups, particularly in the QLB group.
Why it matters
Effective postoperative analgesia is crucial for recovery after open renal surgeries. This study highlights the benefits of regional anesthesia techniques in reducing opioid requirements and improving patient satisfaction, which can enhance recovery protocols.
