About this 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.

Parallel

Treatments tested in this trial

  • Continuous Erector Spinae Plane block

    Procedure/Surgery

    Patients will receive ultrasound-guided continuous bilateral erector spinae plane block at the T7 level with a programmed intermittent bolus (PIB) regimen of Ropivacaine 0.1% (18 mL/3h on the right side and 18 mL/3h on the left side) for 72 hours postoperatively, combined with systemic multimodal analgesia

  • Thoracic Epidural Analgesia (TEA)

    Procedure/Surgery

    Patients will receive a thoracic epidural catheter inserted at the T7-T8 interspace with a continuous basal infusion of Ropivacaine 0.1% at a rate of 5-8 mL/h for 72 hours postoperatively, combined with systemic multimodal analgesia

Trial outcomes

Primary outcomes

1

Postoperative Pain Intensity at Rest at 24 Hours

Postoperative pain intensity evaluated using the Numerical Rating Scale (NRS), where 0 represents no pain and 10 represents the worst imaginable pain. The score will be recorded at rest exactly 24 hours after the completion of the surgery

Time frame
At 24 hours postoperatively

Secondary outcomes

1

Cumulative Morphine Equivalent Consumption

The total amount of intravenous morphine equivalents (in milligrams) administered as rescue analgesia to the patient during the first 24 hours after surgery

Time frame
From 0 to 24 hours postoperatively
2

Postoperative Pain Intensity at Rest and During Coughing up to 72 Hours

Pain intensity scores assessed using the Numerical Rating Scale (NRS, 0-10) both at rest and during coughing at multiple scheduled postoperative time intervals

Time frame
At 0, 1, 3, 6, 12, 48, and 72 hours postoperatively
3

Incidence of Postoperative Complications and Adverse Events

The percentage of patients experiencing technique-related complications (such as local hematoma, catheter dislodgement, block failure) or opioid-related side effects (including postoperative nausea and vomiting, pruritus, urinary retention), as well as pulmonary complications (atelectasis, pneumonia) and hemodynamic instability (hypotension, bradycardia)

Time frame
Up to 72 hours postoperatively
4

Time to Gastrointestinal Recovery

Evaluation of bowel function recovery, measured by the time (in hours) from the end of surgery to the first passage of flatus (first anal exhaust), and the time (in hours) to the first tolerance of oral intake (solid or liquid food)

Time frame
Up to 72 hours postoperatively
