The Effect of Bevel Direction on the Pathway of the Nasotracheal Tube

Not Applicable

Completed

• Conditions: Epistaxis; Intubation Complication

• Registration Number: NCT03740620
• Lead Sponsor: Seoul National University Hospital

Brief Summary

In this study, the subjects are divided into two groups (group I: intervention group = the nasotracheal tube inserted with the bevel of the nasal tube facing the direction of the patient's head, and Group II: conventional group = the bevel of the tube toward the left side of the subject). After the endotracheal tube is introduced, a flexible endoscope is used to evaluate whether the tube is located below the inferior turbinate, i.e. in the lower pathway.

Detailed Description

Primary outcome

* incidence of tracheal tube passing through the lower pathway (beneath the inferior turbinate and immediately above the nasal floor of the nostril) Secondary outcome

* intubation time

* incidence of epistaxis

* severity of bleeding

* Resistance during Insertion of the tracheal tube

Primary Outcome Measures

Name	Time	Method
incidence of the tube in lower pathway	right after completion of the intubation	incidence of tracheal tube passing through the lower pathway (beneath the inferior turbinate and immediately above the nasal floor of the nostril)

Secondary Outcome Measures

Name	Time	Method
intubation time	from the start of the intubation to the completion of the intubation, which is confirmed by the appearance of end-tidal CO2 curve, up to 60 seconds	time to complete endotracheal intubation
incidence and severity of epistaxis	right after completion of the intubation	incidence and severity of epistaxis
