Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

High flow

Apply high-flow nasal oxygenation during apnea with open mouth after adequate preoxygenation. Resume bag-mask ventilation when pulse oximetry drops to 92% or pre-set apnea time has expired.

Group Type EXPERIMENTAL

Apnea with high-flow nasal cannula

Intervention Type DEVICE

Application of oxygenation with high-flow nasal cannula with a rate of 2L/kg/min

Control

Apply nothing during apnea with open mouth after adequate preoxygenation. Resume bag-mask ventilation when pulse oximetry drops to 92% or pre-set apnea time has expired.

Group Type ACTIVE_COMPARATOR

Apnea

Intervention Type OTHER

Apnea without any application of oxygenation
