Nerve block may cut opioid use for cancer pain
NCT ID NCT07211386
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a nerve block called the erector spinae plane block can reduce abdominal pain in people with gastrointestinal cancer. Researchers will compare opioid use and hospital stay length between 25 patients who get the block and a matched group who received standard care. The goal is to see if this procedure can offer effective pain relief with fewer opioids.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- erector spinae plane block (a nerve block procedure)
- What this could lead to
- If it works, this could offer a non-opioid option for managing severe abdominal pain in people with gastrointestinal cancer.
- What could go wrong
- This is a small, early study with only 25 participants, so results may not apply to everyone. The nerve block may not provide enough pain relief for all patients.
