New pain block combo tested for heart surgery recovery
NCT ID NCT07299760
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at two ways to manage pain after coronary artery bypass surgery. All 72 patients received a standard parasternal nerve block, and half also got an additional serratus anterior plane block. Researchers measured pain scores and how much pain medicine patients needed in the first 24 hours after surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bupivacaine (local anesthetic)
- What this could lead to
- If adding the serratus anterior block works better, it could lead to a standard way to reduce pain and opioid use after heart surgery.
- What could go wrong
- This is a small, single-center study with only 72 patients, so results may not apply to everyone. The extra block might not provide meaningful benefit over the standard block alone.
