This study aims to compare the analgesic efficacy of supra-iliac anterior quadratus lumborum block (SA-QLB) and pericapsular nerve group (PENG) block in patients undergoing total hip arthroplasty (THA).
Total hip arthroplasty (THA) is one of the most common elective orthopedic procedures, performed to restore mobility, alleviate pain and improve quality of life in patients with degenerative hip joint disease. Its rate is projected to further increase with aging of the population worldwide.
Pericapsular nerve group (PENG) block is a fascial block targets periarticular sensory branches derived from the femoral, obturator and accessory obturator nerves innervating the anterior hip capsule.
The ultrasound-guided quadratus lumborum block (QLB) is a regional anesthetic technique with many described approaches: the lateral QL (QL1) block, the posterior QL (QL2) block, and the anterior QL (transmuscular) block.

| Measure | Description | Time Frame |
|---|---|---|
| Degree of pain | Each patient will be instructed about postoperative pain assessment with visual analog scale (VAS). VAS (0 represents "no pain" while 10 represents "the worst pain imaginable") | 12 hours postoperatively |
| Measure | Description | Time Frame |
|---|---|---|
| Total morphine consumption | Rescue analgesia of morphine will be given as 3 mg bolus if the VAS > 3 to be repeated after 30 min if pain persists until the visual analog scale (VAS) < 4. VAS will be assessed at post-anesthesia care unit (PACU), 2, 4, 6, 12, 24, and 48 h postoperatively. | 48 hours postoperatively |
