Hidden danger after anesthesia: could lingering muscle relaxants harm recovery?
NCT ID NCT07758868
First seen Aug 11, 2026 · Last updated Aug 12, 2026 · Updated 1 time
Summary
This study investigates how often muscle relaxants used during general anesthesia remain in the body after surgery, a condition called residual neuromuscular blockade. It will follow 160 adults aged 18-90 who are scheduled for post-anesthesia care unit admission after elective surgery. Using a device that measures nerve response, the study aims to see how common this lingering effect is and whether it leads to complications or longer recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If this study succeeds, it could highlight the need for routine quantitative monitoring to reduce postoperative breathing complications and improve recovery.
- What could go wrong
- As an observational study, it cannot prove cause and effect. The findings may not apply to all surgical patients, and the incidence could vary with different monitoring techniques.
