Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) and Laser Laryngeal Surgery
March 11, 2020 updated by: Vladimir Nekhendzy, Stanford University
The Safety and Efficacy of the Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) for Laser Laryngeal Surgery
The purpose of this study is to investigate whether laser laryngeal surgery can be safely and potentially more effectively performed without the use of tracheal intubation 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 cannula: the so called Transnasal Humidified Rapid- Insufflation Ventilatory Exchange (THRIVE).

Time Frame: Induction, 10, 20, 30, 40m following induction, spontaneous ventilation (approximately 1 hour), recovery room (approximately 1 hour)
|
The pH range is 0 to 14, with 7 being neutral.
A pH of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

Stroke Volume Index (SVI)
Time Frame: Induction, 10, 20, 30, 40m following induction, spontaneous ventilation (approximately 1 hour)
|
Stroke volume - the volume of blood ejected from a ventricle at each beat of the heart, equal to the difference between the end-diastolic volume and the end-systolic volume.
The stroke volume index is a method of relating the stroke volume to the size of the person by dividing the stroke volume by the body surface area (BSA) (m^2).
|
Induction, 10, 20, 30, 40m following induction, spontaneous ventilation (approximately 1 hour)

|
Cardiac index: A cardiodynamic measure based on the cardiac output, which is the amount of blood the left ventricle ejects into the systemic circulation in one minute, measured in liters per minute (l/min).
Cardiac output is indexed to a patient's body size by dividing by the body surface area (m^2) to yield the cardiac index.
