Anesthesia mystery: why do some patients relax again after reversal?
NCT ID NCT04048655
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looks at a puzzling event where some patients' muscles relax again after being reversed from anesthesia. Researchers will monitor 120 adults having elective surgery to see how often this happens. The goal is to understand the phenomenon better, not to test a new treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Neostigmine
- What this could lead to
- If successful, this study could help anesthesiologists better understand and prevent unexpected muscle relaxation after surgery.
- What could go wrong
- This is an observational study, not a treatment trial. It only measures how often a phenomenon occurs, so it won't directly lead to a new therapy.
