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.
Patients aged 18-70 years,
Classified as ASA physical status I-III,
Scheduled to undergo single-level lumbar spinal surgery under general anesthesia
Who agree to participate in the study by providing written informed consent
History of bleeding diathesis or current anticoagulant therapy
Known allergy or hypersensitivity to local anesthetics or opioid medications
Infection at the planned block injection site
Previous lumbar spine surgery
Parallel
The Classical Erector Spinae Plane Block
Other interventionThe erector spinae plane block will be performed under ultrasound guidance before the induction of general anesthesia.
Modified Erector Spinae Plane Blocks
Other interventionModified erector spinae plane blocks will be performed under ultrasound guidance before the induction of general anesthesia.
Opioid consumption
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.
Perioperative pain intensity
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
Postoperative Quality of Recovery 15 in Turkish scale
Postoperative nausea and vomiting
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).
