OBJECTIVES: Tracheal intubation of ICU patients is frequently associated with severe hypoxemia. Although noninvasive ventilation reduces desaturation during intubation of severely hypoxemic patients, it does not allow for per-procedure oxygenation and has not been evaluated in mild-to-moderate hypoxemic patients for whom high-flow nasal cannula oxygen may be an alternative. We sought to compare pre- and per-procedure oxygenation with either a nonrebreathing bag reservoir facemask or a high-flow nasal cannula oxygen during tracheal intubation of ICU patients. DESIGN: Prospective quasi-experimental before-after study (ClinicalTrials.gov: NCT01699880). SETTING: University hospital medico-surgical ICU. PATIENTS: All adult patients requiring tracheal intubation in the ICU were eligible. INTERVENTIONS: In the control (before) period, preoxygenation was performed with a nonrebreathing bag reservoir facemask and in the change of practice (after) period, with high-flow nasal cannula oxygen. MEASUREMENTS AND MAIN RESULTS: Primary outcome was median lowest SpO2 during intubation, and secondary outcomes were SpO2 after preoxygenation and number of patients with saturation less than 80%. One hundred one patients were included. Median lowest SpO2 during intubation were 94% (83-98.5) with the nonrebreathing bag reservoir facemask versus 100% (95-100) with high-flow nasal cannula oxygen (p < 0.0001). SpO2 values at the end of preoxygenation were higher with high-flow nasal cannula oxygen than with nonrebreathing bag reservoir facemask and were correlated with the lowest SpO2 reached during the intubation procedure (r = 0.38, p < 0.0001). Patients in the nonrebreathing bag reservoir facemask group experienced more episodes of severe hypoxemia (2% vs 14%, p = 0.03). In the multivariate analysis, preoxygenation with high-flow nasal cannula oxygen was an independent protective factor of the occurrence of severe hypoxemia (odds ratio, 0.146; 95% CI, 0.01-0.90; p = 0.037). CONCLUSIONS: High-flow nasal cannula oxygen significantly improved preoxygenation and reduced prevalence of severe hypoxemia compared with nonrebreathing bag reservoir facemask. Its use could improve patient safety during intubation.
