ICU fasting tradition questioned: new study tests if eating before intubation is safe
NCT ID NCT06510972
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether patients with severe breathing problems in the ICU should be allowed to eat or drink before they need a breathing tube. Currently, patients are often kept fasting to prevent food from entering the lungs, but this can cause discomfort and malnutrition. The study will compare two groups: one that continues eating and one that fasts, to see if eating increases the risk of needing a tube or dying within 96 hours. About 754 adults in intensive care will take part.
