Which pain block works best for hernia repair?
NCT ID NCT05565365
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared two ultrasound-guided nerve blocks—transversalis fascia plane block and erector spinae plane block—for pain relief after inguinal hernia repair. Forty-three men undergoing open hernia surgery received one of the two blocks before the procedure. The goal was to see which block better reduces postoperative pain, measured using a standard pain scale.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bupivacaine
- What this could lead to
- If one block works better, it could improve pain control after hernia surgery, helping patients recover more comfortably.
- What could go wrong
- This is a small, completed study with only 43 men. Results may not apply to women or other surgeries, and individual responses to the blocks can vary.
