Study Overview
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
Study Design
- Study Type
- Interventional
- Allocation
- Randomized
- Intervention Model
- Parallel
- Primary Purpose
- Other
- Masking
- Triple (Participant, Investigator, Outcomes Assessor)
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

Outcomes
Primary Outcomes
Visual analogue scale score
Time Frame: 24 hours
Visual analogue scale score at 1st,6th,12th and 24 h (where 0 is interpreted as no pain, 1-4 mild pain, 5-6 moderate pain, 7-10 severe pain)
Secondary Outcomes

- Opioid consumption(24 hours)
- Time to walk >30 (meter)(24 hours)
- Performance Time(minutes)
- The number of patients who develop block-related complications(24 hours)
- the patients Satisfaction questionnaire(24 hours)
