Summary

This randomized controlled trial aims to evaluate the effect of ultrasound-guided external oblique intercostal (EOI) fascial plane block on postoperative pain control and recovery in pediatric patients undergoing otoplasty with rib cartilage graft under general anesthesia. Participants aged 13 to 18 years will be randomly assigned to receive either EOI block with 0.2% ropivacaine or no block. Primary outcome is total opioid consumption within 24 hours after surgery. Secondary outcomes include NRS pain scores, incentive spirometry performance, incidence of atelectasis, and patient satisfaction.

Interventions

PROCEDURE

Ultrasound-guided External Oblique Intercostal (EOI) Fascial Plane Block

Under general anesthesia, a linear ultrasound probe (6-13 MHz) is placed transversely at the 8th-9th intercostal space along the anterior axillary line. A 22-gauge, 50-80 mm needle is advanced in-plane into the fascial plane between the external oblique and intercostal muscles. After confirming correct needle placement, 0.2% ropivacaine 0.5 mL/kg (maximum 30 mL) is injected. The procedure is performed at the end of otoplasty with rib cartilage graft to provide postoperative analgesia.

PROCEDURE

Standard postoperative pain management (no EOI block)

Participants will not receive the EOI block. All other perioperative management, including general anesthesia and postoperative intravenous patient-controlled analgesia (IV-PCA) with fentanyl, will be identical to the experimental group.
