Do two muscle monitors tell the same story?
NCT ID NCT07739862
First seen Jul 31, 2026 · Last updated Jul 31, 2026
Summary
This study looks at whether two different devices, acceleromyography and electromyography, give matching readings of muscle recovery after anesthesia. It involves adults having gallbladder surgery who receive muscle relaxants. By measuring the train-of-four ratio with both devices at the end of surgery, researchers hope to see if they agree closely enough to guide safe breathing tube removal.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Simultaneous acceleromyography and electromyography monitoring
- What this could lead to
- If these devices agree well, doctors could rely on either one to safely decide when to remove a breathing tube after surgery, potentially reducing complications.
- What could go wrong
- This is a small observational study, and the two devices might not always agree, which could limit how broadly the findings apply. There are no new treatments being tested.
