Summary

Transnasal humidified rapid-insufflation ventilatory exchange(THRIVE), or also termed high flow nasal oxygenation (HFNO) is a method of supplying heated, humidified high concentrations of oxygen via nasal cavity. The purpose of this study is to investigate the effect of HFNO on gastric insufflation in paralyzed anesthetized patients undergoing laryngologic surgery.

Detailed description

HFNO can be used during intraoperative period. HFNO reduces the risk of desaturation and prolongs the safe apnea time, compared with conventional oxygenation. In laryngeal microsurgery, HFNO therapy make possible to perform tubeless anesthesia, providing perfect exposure of structure of the vocal cords. HFNO have a risk for low level of positive pressure can make gastric distension, but gastric reflux or aspiration were not occurred during rapid sequence induction for emergency operation. The purpose of this study is to investigate the effect of HFNO on gastric insufflation in paralyzed anesthetized patients undergoing laryngologic surgery.
