Summary

This prospective, randomized, controlled, assessor-blinded trial will evaluate whether bilateral ultrasound-guided external oblique intercostal block (EOIB) reduces postoperative opioid consumption and improves pain control after laparoscopic cholecystectomy, compared with no block.

Conditions

  • Postoperative Pain
  • Laparoscopic Cholecystectomy

Interventions

OTHER

External oblique intercostal block (EOIB)

Bilateral ultrasound-guided external oblique intercostal block performed under sterile conditions after induction of general anesthesia and before surgical incision. Using an in-plane technique, the block is performed at the level of the 6th rib in the 6th-7th intercostal space. A local anesthetic mixture is injected with a total volume of 15 mL per side (prepared by mixing 0.75% ropivacaine with normal saline).

OTHER

Standard care without regional block

Participants do not receive any regional anesthesia/nerve block (including external oblique intercostal block). All participants receive standard general anesthesia and the same standardized postoperative multimodal analgesia regimen as per protocol, including intravenous patient-controlled analgesia (PCA) with butorphanol.
