Quadro-Iliac Plane Block for Analgesia After Lumbar Microdiscectomy

Recruiting now · Not applicable

Conditions studied: Pain Management

In brief

This study will evaluate whether ultrasound-guided quadro-iliac plane block provides better postoperative pain control than local infiltration analgesia in patients undergoing single-level lumbar microdiscectomy. Adult patients scheduled for elective single-level lumbar microdiscectomy will be randomly assigned to receive either bilateral quadro-iliac plane block plus patient-controlled analgesia or local infiltration analgesia plus patient-controlled analgesia. The main outcome of the study will be total fentanyl consumption during the first 24 hours after surgery. Pain scores, need for rescue analgesia, opioid-related side effects, patient satisfaction, and recovery quality will also be evaluated.
