Distance From the Glottis to the Grille in Children

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.

Treatment and study plan

fiberoptic bronchoscope

Procedure

Distance from grille (the end of shaft in supraglottic airway) to glottis is measured using FOB

Other names: FOB

Primary outcomes

  1. The distance from grille to glottis

    Time frame: 30 seconds after each supraglottic airway insertion

    The distance from grille to glottis is measured using fiberoptic bronchoscopy

Secondary outcomes

  1. FOB view

    Time frame: 30 seconds after each supraglottic airway insertion

    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

  2. Ventilation score

    Time frame: 30 seconds after each supraglottic airway insertion

    no air leak in airway pressure of 15 cmH2O / bilateral chest wall movement/ normal waveform of capnography
