Erector Spinae Plane Block Versus Thoracic Epidural Analgesia for Open Liver Resection

2026년 6월 8일 업데이트: Nguyen Toan Thang

Comparison of Postoperative Analgesic Efficacy Between Erector Spinae Plane Block and Thoracic Epidural Analgesia in Open Hepatectomy: A Randomized Controlled Trial

Background: Open liver resection is associated with severe postoperative pain. While thoracic epidural analgesia (TEA) is considered the gold standard for pain control, its clinical application is often limited by postoperative coagulation profile derangement, which increases the risk of epidural hematoma. Continuous erector spinae plane block (ESPB) has emerged as a promising, safer alternative with a lower risk of bleeding complications. Objective: This study aims to compare the postoperative analgesic efficacy, safety profiles, and impacts on respiratory function between ultrasound-guided continuous ESPB and TEA in patients undergoing elective open liver resection. Hypothesis: The investigators hypothesize that continuous ESPB using a programmed intermittent bolus (PIB) regimen is non-inferior to TEA regarding 72-hour postoperative pain scores at rest, while offering superior hemodynamic stability and fewer technique-related risks.

연구 개요

상세 설명

This is a randomized, controlled, parallel-group, non-inferiority clinical trial conducted at Bach Mai Hospital. Eligible patients scheduled for elective open liver resection will be randomly allocated into one of two groups at a 1:1 ratio: 1. ESPB Group (n = 30): Patients will receive bilateral erector spinae plane catheters placed at the T7 level under ultrasound guidance prior to anesthesia induction. A bolus of 20 mL Ropivacaine 0.2% will be administered on each side. Postoperative analgesia will be maintained for 72 hours using a Programmed Intermittent Bolus (PIB) regimen of Ropivacaine 0.1%: 24 mL every 3 hours on the right side and 12 mL every 3 hours on the left side. 2. TEA Group (n = 30): Patients will receive a thoracic epidural catheter inserted at the T7-T8 interspace. An initial bolus of 10 mL Ropivacaine 0.1% will be given, followed by a continuous basal infusion of Ropivacaine 0.1% at 5-8 mL/h for 72 hours. Multimodal Analgesia: All patients in both groups will receive a standardized general anesthesia protocol and systemic multimodal analgesia, including intravenous paracetamol (1 g every 6 hours) and nefopam (20 mg every 6 hours). Outcomes Evaluation: The primary outcome is the postoperative pain intensity measured by the Numerical Rating Scale (NRS) at rest 24 hours after surgery. Secondary outcomes include NRS pain scores at rest and during coughing at multiple time points up to 72 hours, cumulative 24-hour morphine consumption, hemodynamic parameters, and incidence of adverse events (e.g., hypotension, postoperative nausea and vomiting, hematoma, or catheter failure)
