Yonsei University40 enrolled

Overview

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.

Outcomes

Primary Outcomes

The adequacy of nasotracheal tube tip location in neutral, extended and flexed neck position

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).

Time frame: 1 minute after nasotracheal intubation

Secondary Outcomes

The adequacy of nasotracheal tube cuff location in extended and flexed neck position

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.

Time frame: 1 minute after nasotracheal intubation

The adequacy of nasotracheal tube length

whether the tube cuff cannot be located 3cm below the vocal cords owing to short length of nasotracheal tube.

Time frame: 1 minute after nasotracheal intubation
