Using erector spinae plane block catheters with intrathecal morphine for pain relief after liver surgery

Erector Spinae Plane Block Catheters: The Role in Acute Postoperative Pain After Hepatic Resection With Intrathecal Morphine

Phase 4 Interventional University of California, San Diego · NCT04849455

This study is testing if using special catheters for pain relief along with morphine can help people recovering from liver surgery feel less pain and recover faster compared to standard pain management.

What this trial studies

This clinical trial aims to evaluate whether the addition of erector spinae plane (ESP) catheters enhances postoperative pain management in patients undergoing hepatic resection when combined with intrathecal morphine. The study compares the effectiveness of this multimodal analgesic approach against standard pain management without ESP catheters. By providing a continuous infusion of local anesthetic through the ESP catheters, the trial seeks to improve pain control, reduce opioid consumption, and facilitate quicker recovery and mobilization. The research is particularly focused on addressing the challenges of pain management in patients with limited options due to coagulopathy or decreased metabolism.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old who are scheduled for hepatic resection and can provide informed consent.

Not a fit: Patients who may not benefit include those with severe hepatic disease, chronic high-dose opioid use, or significant allergies to the study medications.

Why it matters

Potential benefit: If successful, this approach could significantly improve postoperative pain control and recovery for patients undergoing liver surgery.

How similar studies have performed: While the use of ESP blocks is gaining traction, this specific combination with intrathecal morphine for hepatic resection is relatively novel and has not been extensively tested in prior studies.
