Conditions
Summary
This prospective, randomized, double-blind study evaluates the analgesic effectiveness of the ultrasound-guided Quadro-Iliac Plane (QIP) block in patients undergoing primary total hip arthroplasty. The QIP block is a recently described fascial plane block. Patients will be randomized to receive either a QIP block with local anesthetic or a sham block with saline. The primary outcome is 24-hour opioid consumption. Secondary outcomes include motor block, dermatomal sensory assessment, pain scores, rescue analgesic requirement, quality of recovery (QoR-15), and opioid-related side effects.

Interventions
An ultrasound-guided Quadro-Iliac Plane block performed in the preoperative period. At the level of the iliac crest, 40 mL of a solution containing 0.25% levobupivacaine and 5 µg/mL epinephrine is injected into the fascial plane between the erector spinae muscle and the quadratus lumborum muscle under aseptic conditions.
A sham block performed using the same ultrasound-guided technique in the preoperative period. At the level of the iliac crest, 40 mL of 0.9% NaCl is injected into the fascial plane between the erector spinae muscle and the quadratus lumborum muscle under aseptic conditions.
