NCT07348419 | Recruiting

• 1 other identifier: OMUKAEK 2025/279
• Study Type: interventional
• Target: 70
• Locations: 1 country
• Sites: 1

Brief Summary

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.

Conditions

Acute Pain; Spinal Stenosis

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

• Postoperative nausea and vomiting

  24 hours

• Quality of recovery 15 scale

  24 hours after surgery

Study Arms (2)

Active Comparator: Group QİPB

OTHER

The Quadro-iliac plane block will be performed 30 minutes before lumbar spine surgery

Other: Quadro-iliac plane block

Active Comparator: Group TLİP

OTHER
