ICU fluid tracking under scrutiny: new study questions daily balance numbers
NCT ID NCT07474116
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether daily weight changes or fluid intake/output records are more reliable for managing fluids in ICU patients. Researchers will observe 55 adults in intensive care, comparing their 24-hour fluid balance to actual weight changes. The goal is to improve how doctors make decisions about fluid treatment.
