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.
