Apneic oxygenation with high-flow nasal oxygen during intubation in hypoxemic ICU patients
Official title: Apneic Oxygenation With High-flow Nasal Oxygenation After Preoxygenation With Noninvasive Ventilation Before Intubation in Hypoxemic Patients in Intensive Care Unit.
Run by University Hospital, Tours · NCT07189338 · Data updated 2026-11-12
This study tests whether using high-flow nasal oxygen during the pause between laryngoscopy and successful intubation helps prevent severe low oxygen levels in ICU patients with hypoxemic respiratory failure.

Is this trial a fit for you?
✓Likely a good fit
Adults in the ICU with hypoxemic acute respiratory failure who require orotracheal intubation and can undergo non-invasive preoxygenation.
✕Probably not a fit
Patients who do not desaturate readily or who have contraindications to HFNO or NIV-based preoxygenation may experience no added benefit.

What this trial studies
This interventional study compares apneic oxygenation with high-flow nasal oxygen (HFNO) to usual care during intubation in adults with hypoxemic acute respiratory failure in the ICU. Eligible participants will be randomized to receive HFNO-apneic oxygenation between laryngoscopy and the moment of successful intubation, or to preoxygenation with non-invasive ventilation without HFNO during the procedure. Outcomes focus on the incidence of severe hypoxemia surrounding intubation, with attention to safety during the apnea and hypoventilation phases. The trial aims to determine if HFNO-apneic oxygenation can reduce hypoxemic events and potentially improve stability during airway management in this high-risk population. Prior data suggest potential benefit of apneic oxygenation in emergency settings, but evidence in hypoxemic ICU patients remains to be clarified.
Why it matters
Potential benefit: If successful, the approach could reduce severe hypoxemia during intubation and improve patient safety in the ICU.
How similar studies have gone: Previous meta-analyses suggest potential reductions in hypoxemia with apneic oxygenation, but results are heterogeneous and ICU-specific evidence is needed.

Show full inclusion / exclusion criteria
Inclusion Criteria: * Patient admitted in the ICU * Indication of orotracheal intubation for Hypoxemic acute respiratory failure defined by: * One sign of acute respiratory distress (respiratory rate \>25/min, dyspnea or the use of accessory respiratory muscle) * AND a PaO2/FiO2 ≤ 200 mmHg (measured or calculated FiO2) within 6 hours before the decision of intubation. For the calculation of FiO2, the FiO2 will be estimated by: FiO2 = 0.21 + 0.03 x (flow of oxygen) (Coudroy, Thorax 2020) * Informed consent from the patient or relatives. An emergency procedure will be possible when necessary. Exclusion Criteria: * \< 18 years old * Need for emergent intubation (i.e. cardiac arrest) * Contraindication to non-invasive ventilation for preoxygenation * Known allergy or contraindication to one of the induction drugs * SpO2 device specific for the study not available * Patients without any healthcare insurance scheme or not benefiting from it through a third party, * Persons under law protection, namely minors, pregnant or breastfeeding women, persons deprived of their liberty by a judicial or administrative decision * Previous participation in the study
