• Conditions: Nasotracheal Intubation

• Registration Number: NCT04499222
• Lead Sponsor: Yonsei University

Brief Summary

The aim of this study is to evaluate the appropriateness of the two kinds of nasotracheal tube (PORTEX POLAR \[Smiths Medical International, Hythe, United Kingdom\], Mallinckrodt TaperGuard \[Covidien, Ireland\]) depth in neutral, extended and flexed neck position when the upper border of the cuff of endotracheal tube is located 3cm below the vocal cords in neutral neck position.

Primary Outcome Measures

Name	Time	Method
The adequacy of nasotracheal tube tip location in neutral, extended and flexed neck position	1 minute after nasotracheal intubation	1. whether the tube tip is located above the carina in neutral, extended and flexed neck position when the upper border of the cuff of endotracheal tube is fixed 3cm below the vocal cords (in neutral neck position).; 2. the distance from the carina to the tube tip in neutral, extended and flexed neck position when the upper border of the cuff of endotracheal tube is fixed 3cm below the vocal cords (in neutral neck position).

Secondary Outcome Measures

Name	Time	Method
The adequacy of nasotracheal tube cuff location in extended and flexed neck position	1 minute after nasotracheal intubation	whether the tube cuff is located below the vocal cords in extended and flexed neck position when the upper border of the cuff of endotracheal tube is fixed 3cm below the vocal cords in neutral neck position.
The adequacy of nasotracheal tube length	1 minute after nasotracheal intubation	whether the tube cuff cannot be located 3cm below the vocal cords owing to short length of nasotracheal tube.
