Summary

This multicenter, randomized, controlled study aims to compare the analgesic efficacy of Quadro Iliac Plane Block (QIPB) and Erector Spinae Plane (ESP) Block in lumbar vertebra surgeries. The study will evaluate postoperative pain management, opioid consumption, side effects, hospital stay duration, and patient satisfaction. Patients scheduled for single-level lumbar disk herniation surgery will be randomized to receive either the QIPB or ESP block before awakening from anesthesia. Pain scores will be measured at multiple postoperative time points, and opioid consumption will be monitored using patient-controlled analgesia (PCA). The study seeks to identify the most effective and safe method for postoperative pain management in lumbar surgeries.

Interventions

PROCEDURE

Quadro Iliac Plane Block (QIPB)

The Quadro Iliac Plane Block (QIPB) will be performed pre-awakening in patients undergoing lumbar vertebra surgeries. Using a low-frequency convex ultrasound transducer (2-6 MHz), the spinal process will be identified at the L3 level in a prone-positioned patient. The transducer will be moved laterally to locate the transverse process within the erector spinae muscle and then rotated to the parasagittal plane to identify the Quadratus Lumborum Muscle (QLM) attachment to the iliac crest. A 22G x 100 mm block needle will be advanced under ultrasound guidance, and 50 mg (0.25%) bupivacaine will be injected bilaterally into the fascia beneath the QLM. This technique is designed to provide effective postoperative pain control by blocking the nerves in the quadratus lumborum plane.

PROCEDURE

Erector Spinae Plane Block (ESP)

The Erector Spinae Plane Block (ESP) will also be performed pre-awakening. A linear ultrasound probe will be placed transversely at the level of the L3 vertebra to visualize the transverse process. A block needle will be advanced under ultrasound guidance until it touches the transverse process, after which the needle will be withdrawn 1 mm. Fifty milligrams (0.25%) bupivacaine will then be administered bilaterally. The ESP block aims to provide postoperative analgesia by blocking sensory nerves in the erector spinae plane.
