View on ClinicalTrials.gov →
Summary
The aim of this study is to compare the analgesic efficacy of ultrasound-guided (USG) lumbar Erector Spinae Plane Block (ESPB) performed by an anesthesiologist versus a "free-hand" ESPB performed intraoperatively by the surgeon in patients undergoing Unilateral Biportal Endoscopic Discectomy (UBE). The investigators hypothesize that Us-guided would provide more effective analgesia, and USG-guided application might provide more precise local anesthetic spread.
