First seen Jun 26, 2026 · Last updated Jul 10, 2026 · Updated 2 times
Summary
This study tests whether a numbing injection called a TAP block can lower the amount of pain medication needed after lower spine surgery. 80 adults scheduled for anterior lumbar fusion will be randomly assigned to receive either the TAP block or a placebo. Their pain and medication use will be tracked for 3 days after surgery.

- Active substance
- Levobupivacaine
- What this could lead to
- If it works, this could offer a way to reduce pain and the need for strong painkillers after spine surgery.
- What could go wrong
- This is a small, early-stage trial with only 80 people. The nerve block may not reduce pain significantly, and there is a small risk of side effects like allergic reaction or infection.
