Acute Pain, Spinal Stenosis Lumbar
Conditions
Brief summary
The investigators aim to compare the postoperative analgesic efficacy of the classical erector spinae plane block and the modified erector spinae plane block in the management of postoperative analgesia after lumbar disc surgery.
Detailed description
Lumbar spinal stenosis may lead to variable signs and symptoms such as low 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 reduces opioid-related side effects and is associated with earlier mobilization, shorter hospital stay, and improved patient satisfaction. In patients undergoing lumbar disc surgery, the classical erector spinae plane block and the modified erector spinae plane block provide effective analgesia for postoperative pain control.
Interventions
OTHERThe Classical Erector Spinae Plane Block
The erector spinae plane block will be performed under ultrasound guidance before the induction of general anesthesia.
OTHERModified Erector Spinae Plane Blocks
Modified erector spinae plane blocks will be performed under ultrasound guidance before the induction of general anesthesia.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Opioid consumption | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Perioperative pain intensity | 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'). |
| Quality of recovery 15 scale | 24 hours after surgery | Postoperative Quality of Recovery 15 in Turkish scale |
| Postoperative nausea and vomiting | 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). |
