Non-inferiority of Continuing Oral Intake Versus Fasting in Patients With Acute Respiratory Failure
France754 participantsStarted 2025-02-05
Plain-language summary
Fasting in intensive care is mainly studied in mechanically ventilated patients or those in the weaning phase. Recent research challenge the common assumption of fasting and suggests that continuing enteral nutrition before extubation may be beneficial. Fasting is also practiced before procedures (e.g., tracheostomy, endoscopy) or surgeries, based on anesthetic guidelines. Yet, no data address fasting in non-intubated ICU patients with acute respiratory failure, despite frequent caloric deficits and inadequate nutritional intake.
Aspiration risk often justifies fasting, but studies indicate that swallowing reflexes remain intact in patients receiving high-flow nasal oxygen or non-invasive ventilation. Moreover, although intubation carries a 2-5.9% aspiration risk, rapid sequence induction mitigates this, questioning the necessity of preventive fasting. Despite its prevalence, this practice lacks scientific validation and guideline support.
Patient discomfort is also significant. Hunger and thirst are major sources of distress, and evidence from anesthesiology suggests that allowing fluid intake pre-anesthesia reduces discomfort. Extrapolating these findings to ICU patients could improve well-being.
In conclusion, fasting in ICU patients may contribute to discomfort, dehydration, and malnutrition, while its protective benefits remain uncertain. We hypothesize that maintaining oral intake does not increase the risk of intubation or aspiration-related complications.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
