Can muscle loss predict death in the ICU?
NCT ID NCT07280039
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study will follow 386 critically ill patients on breathing machines to see if losing 10% or more of thigh muscle within the first week in the hospital is linked to a higher chance of dying within 28 days. Researchers will use ultrasound to measure muscle size. The goal is to better understand how muscle wasting affects survival in intensive care.
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 successful, this could help doctors identify high-risk ICU patients earlier and guide interventions to prevent muscle loss.
- What could go wrong
- This is an observational study, not a treatment trial. It only looks for a link, not a cause, and results may not apply to all ICU patients.
