Brief summary
Whether trans muscular QLB provides postoperative analgesia compared with LPB after thigh lift surgery
Detailed description
Adequate analgesia after spiral thigh reduction (thigh lift) is essential for early mobilization and patient satisfaction. Quadratus lumborum block (QLB) has shown analgesic efficacy comparable to lumbar plexus block (LPB) for hip area surgery with potential advantages in motor-sparing and safety
Interventions
With the patient lateral decubitus position, a low-frequency curvilinear probe in the 'Shamrock' view at L2-L4. In-plane posterior-to-anterior needle advancement through the Quadratus lumborum to the interfascial plane anterior to QL and posterior to Psoas major. Inject 30 mL Bupivacaine 0.25% after negative aspiration and hydrodissection to confirm proper spread . Then the patient will be turned to the other side, and the block will be done with the same technique
Lateral decubitus, Shamrock view to identify the Psoas compartment; in-plane needle advancement to the Psoas compartment adjacent to the transverse process. Inject 30 mL of Bupivacaine 0.25% in 5 mL increments, aspirating frequently. This will be done in the same position for both sides

Study design
Masking description
Computer-generated randomization in variable blocks; allocation sealed in opaque envelopes. Blocks performed by an anesthesiologist not involved in postoperative assessment. Patients and outcome assessors are blinded. Drape and opaque dressings conceal injection sites for both groups to preserve blinding
Intervention model description
Prospective, randomized, parallel-group, double-blind, clinical trial. Primary endpoint: time for first analgesic request postoperatively. Key secondary endpoints: 24-hour opioid consumption (oral morphine equivalents), pain on movement at 6/12/24 hours, time to first ambulation, postoperative nausea/vomiting (PONV), block performance time, and block-related complications. Hypothesis: QLB is non-inferior to LPB for 24-hour pain scores and will yield less motor weakness
