Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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. |
