Which nerve block eases kidney surgery pain best? a Head-to-Head trial
NCT ID NCT07726550
First seen Jul 24, 2026 · Last updated Jul 24, 2026
Summary
This trial compares two ultrasound-guided nerve block techniques—erector spinae plane block and modified external oblique intercostal plane block—for controlling pain after open kidney surgery. Sixty adults scheduled for elective open nephrectomy will receive one of the two blocks before surgery, and researchers will measure pain scores, opioid use, and side effects over the first 24 hours. The goal is to see which approach provides better pain relief and recovery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- two ultrasound-guided nerve block procedures: erector spinae plane block and modified external oblique intercostal plane block, using bupivacaine
- What this could lead to
- If one nerve block proves superior, it could become the preferred method for managing pain after open kidney surgery, potentially reducing opioid use and improving recovery.
- What could go wrong
- This is a small, early-stage trial with only 60 participants, so results may not apply to all patients. Both techniques are already in use, so the difference may be small.
