Summary

This study aims to compare the analgesic efficacy of two different ultrasound-guided nerve blocks-the External Oblique Intercostal Block (EOIB) and the Subcostal Transversus Abdominis Plane (TAP) block-in patients undergoing minimally invasive hepatectomy. All participants will receive standardized general anesthesia and perioperative care at Seoul National University Hospital. Following anesthesia induction, patients will be randomly assigned to receive either an EOIBor a subcostal TAP block with 0.375% ropivacaine to provide regional pain relief. Postoperative pain will be managed using a combination of scheduled non-opioid analgesics and a fentanyl-based patient-controlled analgesia (PCA) device. The primary objective is to evaluate which regional technique more effectively reduces cumulative opioid consumption during the first 24 hours after surgery. Additionally, the study will assess pain intensity using the Numerical Rating Scale (NRS), the incidence of postoperative nausea and vomiting, and the overall recovery profile, including the time to first ambulation.

Conditions

  • Hepatectomy

Interventions

PROCEDURE

External Oblique Intercostal Block

Following the induction of general anesthesia, patients in this group will receive an ultrasound-guided bilateral external intercostal fascial plane block. A total of 40 mL of 0.375% ropivacaine (20 mL per side) will be injected into the plane between the external intercostal muscle and the internal intercostal muscle at the T6-7 or T7-8 level.

PROCEDURE

TAP Block

Following the induction of general anesthesia, patients in this group will receive an ultrasound-guided bilateral subcostal transversus abdominis plane block. A total of 40 mL of 0.375% ropivacaine (20 mL per side) will be injected into the fascial plane between the internal oblique and transversus abdominis muscles along the subcostal margin.
