About

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?

Full 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.
