Summary

This study aims to evaluate the effect of high-flow nasal oxygenation on safe apnea time for children undergoing general anesthesia, with their mouth open.

Description

Oxygenation via high-flow nasal cannula is gaining popularity in various clinical settings. It is known to increase apnea time for apneic patients including children. However, high-flow nasal cannula is known to be ineffective when the patient's mouth is kept open.

When trying to intubate the patient during induction of anesthesia, the patient should be apneic with administration of neuromuscular blocking agent, and the mouth should be open for introduction of laryngoscope.

We designed a prospective randomized controlled study to evaluate the effect of high-flow nasal oxygenation in the aforementioned setting for trying to intubate the patient.
