Nasotracheal intubation
Brief summary
The goal of this prospective randomized study is to compare the effect of nasal tip lifting during nasotracheal intubation. The question the investigators are trying to answer is: If the nasal tip is tilted, will the E-tube be more likely to enter the lower passage during nasal intubation?
Detailed description
There are three nasal turbinates inside the nasal cavities. Each nasal cavity is divided into four spaces from these nasal turbinates, but the two spaces separated by the upper nasal turbinate are too narrow to be clinically meaningful. So when performing nasotracheal intubation, the tube enters one of the two spaces in low part divided into the lower turbinate. The middle turbinate, unlike others, a large number of blood vessels and nerves are distributed. Therefore, less hemorrhage might occurs when the tracheal tube enters into the lower pathway below the lower turbinate because the tube would not scratching the middle turbinate. The hypothesis of this study is that the method 'sniffing position and nasal tip lifting' increases possibility to enter into lower pathway when the tube enters the nasal cavity. The purpose of a present study was to investigate the effect of 'sniffing position & nose' on the intranasal route of the tube.
Interventions
PROCEDURESniffing position
All procedure is done under sniffing position.
PROCEDURENasal tip lifting
Before inserting the endotracheal tube to patient's nose, the researcher lift up the nose tip.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of patients with nasal endotraheal tube in the lowest nasal pathway. | Through study completion, an average of 1 year | After the endotracheal intubation is completed, the experimenter confirms by a fiberoptic bronchoscope which path the endotracheal tube is located. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Nasal bleeding | Through study completion, an average of 1 year | After nasotracheal intubation, the researcher confirm there is nasal bleeding or not. And if bleeding observed, the experimenter would check the amount. |
| Intubation time | Through study completion, an average of 1 year | Check the time from initiation of insertion of E-tube to finish passing nasal path and to finish intubation. |
