Brief summary

Tracheal intubation in operating room for patients at risk of difficult intubation remains a critical event. The aim of this study is to determine whether Nasal High Flow Therapy by nasal cannula Optiflow® administered before and during intubation is more efficient than the standard care for pre-oxygenation and oxygenation during anticipated difficult intubation

Detailed description

This study will be designed as followed: Patients will be randomized in 2 groups: * Preoxygenation during 4 minutes with High Flow Nasal Cannula (60l/min FiO2 = 1) before and during intubation. The device will be maintained in place throughout the intubation procedure (including fiber-optic or laryngoscopic) in order to achieve oxygenation. * Or Standard Preoxygenation during 4 minutes with FIBROXY® (Fiber-optic intubation) or standard facial mask (Laryngoscopic intubation), at FiO2=100%. FIBROXY mask will be maintained in place during the fiberoptic procedure. Standard facial mask, will be removed after the crash induction.

Interventions

DEVICEPreoxygenation with high flow therapy by nasal cannula

Preoxygenation during 4 minutes with High Flow Nasal Cannula (60l/min FiO2 = 1) before fiber-optic or laryngoscopic intubation. The device will be maintained in place throughout the intubation procedure in order to achieve oxygenation.

DEVICEPreoxygenation by standard Facial mask

* For Fiber-optic intubation: patients will receive a 4 minutes FIBROXY facial mask preoxygenation with FiO2=100%. The FIBROXY facial mask will be maintained in place during the intubation procedure. * For Laryngoscopic intubation: patients will receive a 4 minutes standard facial mask preoxygenation with FiO2=100%. The standard facial mask will be removed after crash induction to proceed to intubation.

Design outcomes

Primary

MeasureTime frameDescription
Incidence of desaturation below 95% or manual facial mask reventilation during ETI procedure.4 minutesTo determine whether High-Flow nasal cannula used for preoxygenation and oxygenation during intubation, is more efficient than standard care during difficult intubation. This outcome will be assessed from the beginning of the preoxygenation period to the end of orotracheal intubation by monitoring the pulse oxymetry.

Secondary

MeasureTime frameDescription
Improvement of quality of preoxygenation4 minutesduration of proceedings
Reduction in side effects incidence related to intubation6 hours
Morbi-mortality during surgery.6 hoursPer and postoperative complication rate
