NCT07348523 | Recruiting

• 1 other identifier: OMUKAEK 2025/247
• Study Type: interventional
• Target: 60
• Locations: 1 country
• Sites: 1

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.

Conditions

Acute Pain; Spinal Stenosis Lumbar

Outcome Measures

Primary Outcomes (1)

• 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.

  24 hours

Secondary Outcomes (3)

• Perioperative pain intensity

  24 hours

• Quality of recovery 15 scale

  24 hours after surgery

• Postoperative nausea and vomiting

  24 hours

Study Arms (2)

Active Comparator: Group K-ESP

ACTIVE COMPARATOR

The erector spinae plane block will be performed 30 minutes before lumbar spine surgery.

Other: The Classical Erector Spinae Plane Block

Active Comparator: Group M-ESP

ACTIVE COMPARATOR

The modified erector spinae plane block will be performed 30 minutes before lumbar spine surgery.

Other: Modified Erector Spinae Plane Blocks

Interventions

The Classical Erector Spinae Plane Block OTHER

The erector spinae plane block will be performed under ultrasound guidance before the induction of general anesthesia.

Active Comparator: Group K-ESP

Modified Erector Spinae Plane Blocks OTHER

Modified erector spinae plane blocks will be performed under ultrasound guidance before the induction of general anesthesia.

Active Comparator: Group M-ESP
