Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Tracheal intubation of critically ill patients is associated in the intensive care unit (ICU) with significant complications and morbidity. Patient desaturation is one of the most common complications that may lead to cardiac arrest despite pre-intubation oxygenation. Preoxygenation can be improved by the use of non-invasive ventilation, but this technique can be cumbersome to implement in the context of urgent intubation and more importantly it does not insure oxygenation during intubation. High flow nasal cannula oxygen therapy is a technique that has been shown to improve patient oxygenation in the context of acute hypoxemic respiratory failure. It bears the potential to be of clinical benefit in the setting of tracheal intubation in the ICU to ensure patient safety. The purpose of this study is to compare pre- and per-intubation (during intubation) oxygenation with either a conventional high FiO2 oxygen bag reservoir facemask (current standard practice) or high flow nasal cannula oxygen therapy (new practice to be implemented in our ICU).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Pre-oxygenation is ensured in our ICU with a high FiO2 nonrebreathing facemask, except in patients already under high flow nasal cannula oxygen therapy because of acute hypoxemic respiratory failure. A nasal catheter is positioned to ensure a low oxygen flow during laryngoscopy. Whether or not all patients should benefit from high flow nasal cannula oxygen therapy for pre-oxygenation remains unknown. In order to improve quality of care delivered to our patients and in anticipation of a change in our practice, we decided to record prospectively oxygen parameters during and immediately of intubation using a facemask and to compare them with parameters obtained in patients intubated after our change in practice. The change of practice consists in the systematic use of high flow nasal cannula oxygen therapy to ensure pre and during procedure (tracheal intubation)oxygenation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

conventional high FiO2 bag reservoir facemask

this group of patients is intubated according to our current practice that requires the use of a high FiO2 nonrebreathing with bag reservoir facemask to ensure preoxygenation in patients requiring tracheal intubation. a small nasal catheter is inserted just before laryngoscopy to ensure a low oxygen flow to allow oxygenation during laryngoscopy.

No interventions assigned to this group

high flow nasal cannula oxygen

we wish to change our standard practice of preoxygenation and expand our use of high flow nasal cannula oxygen therapy to the tracheal intubation setting. Currently, used of high flow oxygen nasal cannula oxygen therapy to ensure oxygenation during intubation is limited to the patients already under high flow nasal cannula oxygen. the change of practice consists in the systematic use of high flow nasal cannula oxygen therapy in all patients requiring tracheal intubation in the ICU.
