Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) Could Decrease the Incidence of Oxygen Desaturation During Suspension Laryngoscopy: a Randomized Controlled Trial (Optilaryngo)

Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) Could Decrease the Incidence of Oxygen Desaturation During Suspension Laryngoscopy: a Randomized Controlled Trial

Suspension laryngoscopy is realised during apnea. In effect, surgeons are in the mouth of the patient and we can't have access at the aiways.

So investigators like to use a Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) to increase time of apnea and decrease the impact of oxygen desaturation.

Inclusion Criteria:

• suspension laryngoscopy

Exclusion Criteria:

• THRIVE contraindication:
• epistaxis
• undrained pneumothorax
• Recent gastroesophageal surgery (1months)
• Skull Fractures
