New study tests better pain relief after liver surgery
NCT ID NCT03238430
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at two methods to control pain after liver surgery: continuous wound infiltration with a local anesthetic (ropivacaine) and a single spinal injection of morphine. The goal was to see which approach reduces the need for additional morphine and lowers the chance of chronic pain at 3 and 6 months after surgery. A total of 186 patients took part, and the results could help improve recovery after liver operations.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ropivacaine and intrathecal morphine
- What this could lead to
- If successful, this could show that one of these methods is better at controlling pain after liver surgery, reducing the need for morphine and lowering the risk of long-term pain.
- What could go wrong
- This is a completed Phase 2/3 trial with 186 participants, so results are available but may not apply to all patients. The study compares existing techniques, so no breakthrough is expected.
