Official title
Comparison of the Postoperative Analgesic Efficacy of the Quadro-Iliac Plane Block and the Classical Thoracolumbar Interfascial Plane Block in Single-Level Lumbar Disc Surgery: A Prospective Randomized Controlled Trial
Overview
The investigators aim to compare the postoperative analgesic efficacy of the classical thoracolumbar interfascial plane block and the Quadro-iliac plane block for postoperative analgesia management after lumbar disc surgery.
Detailed description
Lumbar spinal stenosis can lead to variable signs and symptoms such as back pain, radiating pain to the lower extremities, and reduced walking capacity. Lumbar disc surgery itself causes significant pain due to extensive dissection and muscle retraction during the procedure. A multimodal analgesic approach is preferred for postoperative pain management after lumbar spine surgery. The addition of regional anesthesia techniques can reduce opioid-related side effects and is associated with earlier mobilization, shorter hospital stay, and improved patient satisfaction.
For patients undergoing lumbar disc surgery, the classical thoracolumbar interfascial plane (TLIP) block and the Quadro-iliac plane block (QIPB) provide effective analgesia for postoperative pain control.
Interventions
- Other Quadro-iliac plane block
Quadro-iliac plane block will be performed under ultrasound guidance before the induction of general anesthesia. - Other Classical thoracolumbar interfascial plane block
Classical thoracolumbar interfascial plane block will be performed under ultrasound guidance before the induction of general anesthesia.
Primary outcome measures
- Opioid consumption [Time frame: 24 hours]
Secondary outcome measures (3)
- Perioperative pain intensity [Time frame: 24 hours]
- Postoperative nausea and vomiting [Time frame: 24 hours]
- Quality of recovery 15 scale [Time frame: 24 hours after surgery]
