Comparing two types of nerve blocks for pain management after lumbar surgery
Official title: Comparison of the Effects of Thoracolumbar Interfascial Plane Block and Quadro Iliac Plane Block on Postoperative Opioid Consumption After Lumbar Microsurgery: A Randomized Controlled Trial
Run by Medipol University · NCT06851533 · Data updated 2026-11-12
This study is testing two different nerve block techniques to see which one helps people have less pain and use fewer opioids after lumbar surgery.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 to 80 who are scheduled for lumbar microdiscectomy and have an ASA physical status of I to III.
✕Probably not a fit
Patients with known allergies to local anesthetics, significant drug allergies, or pre-existing psychiatric or neurological disorders may not benefit from this study.

What this trial studies
This study evaluates the effectiveness of two regional anesthesia techniques, the Thoracolumbar Interfascial Plane (TLIP) block and the Quadro Iliac Plane Block, in reducing postoperative opioid use following lumbar microdiscectomy. The research aims to determine which method provides better pain control and fewer opioid-related side effects, such as nausea and respiratory depression. Patients aged 18 to 80 scheduled for this surgery will be included, and their postoperative pain levels will be assessed using a Numeric Rating Scale. The study seeks to enhance patient recovery by minimizing opioid consumption through effective pain management strategies.
Why it matters
Potential benefit: If successful, this study could lead to improved pain management techniques that reduce reliance on opioids after lumbar surgery.
How similar studies have gone: While there is limited evidence directly comparing these two specific nerve block techniques, regional anesthesia has shown promise in improving postoperative pain management in similar contexts.
