Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Sniffing group
Before intubation, the patient's shoulder is supported by a 5cm pillow to make neck flexion with extension of atlanto-occipital joint, confirming that the external auditory meatus and sternal notch plane are horizontal and aligned. Then, nasotracheal intubation is performed with a reinforced tube (Mallinckrodt Medical, Dublin, Ireland) using video-laryngoscope (AceScope, AceMedical, Seoul, Korea).
Head position
Before nasotracheal intubation, patient's head is positioned to one of three positions according to assigned group: sniffing, neutral or flexed position.
Neutral group
Before intubation, the patient's head is placed without a pillow on the bed. Then, nasotracheal intubation is performed with a reinforced tube (Mallinckrodt Medical, Dublin, Ireland) using video-laryngoscope (AceScope, AceMedical, Seoul, Korea).
Head position
Before nasotracheal intubation, patient's head is positioned to one of three positions according to assigned group: sniffing, neutral or flexed position.
Flexed group
Before intubation, the patient's neck is flexed with pads until the chin touches the chest. Then, nasotracheal intubation is performed with a reinforced tube (Mallinckrodt Medical, Dublin, Ireland) using video-laryngoscope (AceScope, AceMedical, Seoul, Korea).
