Clinical Trial Summary

Ambu AuraGain, I-gel, Air-Q intubating laryngeal airway are the most commonly used supraglottic airway. In children, they can be used as intubation conduits. However, there has been no guideline for optimal insertion depth of endotracheal tube through those supraglottic airway. In this study, the investigators will measure the distance from grille of those supraglottic airways to glottis using fiberoptic bronchoscope in children undergoing anesthesia. This distance allows us to predict an appropriate depth of endotracheal tube when it should be inserted through each supraglottic airway.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The distance from grille to glottis	The distance from grille to glottis is measured using fiberoptic bronchoscopy	30 seconds after each supraglottic airway insertion
Secondary	FOB view	score 1: no visible glottis, score 2: visible glottis and anterior epiglottis, score 3: visible glottis and posterior epiglottis, and score 4: only glottis visible	30 seconds after each supraglottic airway insertion
Secondary	Ventilation score	no air leak in airway pressure of 15 cmH2O / bilateral chest wall movement/ normal waveform of capnography	30 seconds after each supraglottic airway insertion
