ESP Block Vs. QIPB for Lumbar Stabilization Surgery
Sponsor: Antalya City Hospital
Summary
This randomized clinical trial aims to evaluate and compare the analgesic efficacy and functional outcomes of the quadro-iliac plane block (QIPB) and the erector spinae plane block (ESPB) in patients undergoing lumbar stabilization surgery. The primary outcome is the Numeric Rating Scale (NRS) within the first 48 hours after surgery. Secondary outcomes include postoperative total opioid consumption, incidence of quadriceps motor block, time to first ambulation, block performance time, falls, length of hospital stay, block-related complications (hematoma, local anesthetic systemic complications, vascular puncture, and infection), patient satisfaction assessed using a Likert scale, and incidence of postoperative nausea and vomiting.

Quadro iliac Plane Block
Participants allocated to the QIPB group will receive an ultrasound-guided quadro-iliac plane block after the induction of general anesthesia. Following standard aseptic preparation, 30 mL of 0.25% bupivacaine will be administered into the target fascial plane under ultrasound guidance after confirming the absence of blood on aspiration.
