Acerca de la investigación
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.
Leer la descripción completa
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.

Qué evalúan los investigadores
Estas medidas indican qué se estudia. No prueban que un tratamiento funcione.
Medidas principales
Opioid consumption
Plazo: 24 hours
In the postoperative period, patients will be given opioids according to their pain density with a patient-controlled device, and the daily Morphine consumption in Patient Controlled Analgesia device will be collected and compared between groups.
Medidas secundarias
Perioperative pain intensity
Plazo: 24 hours
Changes in the Numerical Rating Scale (NRS) will be recorded at rest and during movement. The participant's baseline NRS will be recorded, followed by measurements before and after neuraxial positioning and up to 24 hours post-surgery.
The NRS is a unidimensional measure of pain intensity in adults. It is a segmented numerical version of the Visual Analog Scale (VAS) where the participant selects a whole number (0-10) that best represents the intensity of their pain. The 11-point numerical scale ranges from '0' representing one end of the pain spectrum (e.g. 'no pain') to '10' representing the other end (e.g. 'worst imaginable pain').
Postoperative nausea and vomiting
Plazo: 24 hours
Postoperative nausea and vomiting (PONV):
During follow-up, patients who experience nausea or vomiting will be evaluated using a verbal descriptive PONV scale (0=None, 1=Mild nausea, 2=Moderate nausea, 3=Single episode of vomiting, 4=More than one episode of vomiting).
Quality of recovery 15 scale
Plazo: 24 hours after surgery
Postoperative Quality of Recovery 15 in Turkish scale. The QoR-15 (Quality of Recovery-15) questionnaire is a simple and practical tool used to assess postoperative recovery.
It consists of 15 items, each scored on a numeric scale from 0 to 10, resulting in a total score ranging from 0 to 150.
Based on the total score, postoperative recovery is categorized as follows:
136-150: Excellent recovery
122-135: Good recovery
90-121: Moderate recovery
0-89: Poor recovery
