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

Conditions

• Analgesia

Interventions

Type	Name	Description
OTHER	Ultrasound-Guided Trans-muscular QLB	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
OTHER	Ultrasound-Guided Posterior Lumbar Plexus (Psoas Compartment) Block	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
