High Flow Nasal Cannula for Safe Apnea

Effect of High-flow Nasal Oxygenation on Safe Apnea Time in Children With Open Mouth

This is a prospective randomized controlled trial comparing high flow nasal cannula and buccal oxygenation as method of oxygenation during apnea in children.

This is a prospective randomized controlled trial comparing two oxygenation methods for prolongation of apnea time in children aged 0 to 10 years old.

This study measures time for the pulse oximetry drop from 100% to 92% after oxygenation with 100% oxygen, applying high flow nasal cannula or buccal oxygen insufflation via an oral Ring-Adair-Elwyn endotracheal tube connected to oxygen.

Inclusion Criteria:

• Children under 11 years old undergoing general anesthesia with American Society of Anesthesiologists Physical Status 1 or 2.

Exclusion Criteria:

• Refusal of enrollment from one or more legal guardians of the patient
• Plan of usage of supraglottic airway device as airway maintenance device
• Presence of upper respiratory tract infection of lung disease
• Premature infants younger than postconceptual age of 40 weeks
• Anticipation of difficult bag-mask ventilation due to facial anomaly or micrognathia
• Other conditions that are considered inappropriate for the study
