Can a body scanner save lives in the ICU?
NCT ID NCT07142083
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study compares two ways of giving fluids to patients in the intensive care unit after major surgery. One group gets fluids based on a daily body scan that measures water inside and outside cells, while the other group gets fluids based on standard checks like blood pressure and urine output. The main goal is to see if the scan-guided approach lowers the chance of death within 28 days. About 80 patients will take part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Bioelectrical Impedance Analysis (Body Composition Monitor device)
- What this could lead to
- If successful, this could show that using a simple body scan to guide fluids saves more lives in the ICU after major surgery.
- What could go wrong
- This is a small, early-stage study with only 80 patients, so results may not apply widely. The device might not improve outcomes over standard methods.
