Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) and Short Laryngologic Surgery

Completed · Not applicable

Conditions studied: Laryngologic Surgical Procedures

In brief

The purpose of this study is to investigate whether selected, short laryngologic surgical procedures can be safely and potentially more effectively performed without the use of endotracheal tube or jet ventilation, under completely tubeless conditions. The patient's gas exchange will be supported by rapid insufflation of high-flow oxygen through specialized nasal cannulae: the so called Transnasal Humidified Rapid- Insufflation Ventilatory Exchange (THRIVE).
