Comparison of the Postoperative Analgesic Effects of Intrathecal Morphine and Bi-level Erector Spinae Plane Block in Liver Transplantation Donors

Not applicable Interventional Ankara Etlik City Hospital · NCT07123740

This will try spinal (intrathecal) morphine versus a bi-level erector spinae plane block to reduce pain and opioid use in living liver donors after hepatectomy.

What this trial studies

This interventional study compares two regional anesthesia techniques—intrathecal morphine (ITM) and a bi-level erector spinae plane block (ESPB)—for postoperative pain control in living liver donors. Participants who meet inclusion criteria will receive one of the two analgesic approaches around the time of donor hepatectomy. Outcomes will include postoperative pain scores, perioperative opioid consumption, and procedure-related adverse effects. The goal is to determine which technique provides better pain relief and fewer opioid-related problems to support faster recovery.

Who should consider this trial

Good fit: Ideal candidates are living liver donors aged 18–65 years with ASA physical status I–II and a BMI of 18–30 kg/m2 who are cleared for donor hepatectomy at the enrolling center.

Not a fit: Patients outside the age or BMI ranges, with ASA III or higher, bleeding diathesis, or other contraindications to neuraxial or regional anesthesia are unlikely to qualify or benefit from this comparison.

Why it matters

Potential benefit: If successful, the preferred technique could improve immediate postoperative pain control, reduce opioid requirements, and speed recovery for living liver donors.

How similar studies have performed: Regional techniques such as intrathecal morphine and erector spinae plane blocks have shown reduced postoperative pain and opioid use in various surgeries, but direct head-to-head data in living liver donors are limited.
