External oblique intercostal (EOI) block to reduce pain after otoplasty with rib cartilage graft

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized controlled trial at Seoul National University Children's Hospital will assign 13–18-year-old patients undergoing otoplasty with rib cartilage graft to receive either an ultrasound-guided external oblique intercostal (EOI) fascial plane block with 0.2% ropivacaine or no block in addition to standard anesthesia and postoperative care. The primary outcome is total opioid consumption in the first 24 hours after surgery. Secondary outcomes include numeric rating scale pain scores, incentive spirometry performance, incidence of atelectasis, and patient satisfaction. The study will determine whether adding the EOI block improves early pain control and respiratory recovery after chest-wall harvest for otoplasty.
