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

Seoul National University

Status: Completed

Conditions: Epistaxis; Intubation Complication

Treatments: Procedure: Bevel facing leftward of the patient; Procedure: Bevel facing the cephalad direction of the patient

Study type: Interventional

Funder types: Other

Identifiers

NCT03740620

Details and patient eligibility

About

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.

Full 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

Enrollment: 68 patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• a patient who will take operation which needs nasotracheal intubation under general anesthesia

---

68 participants in 2 patient groups

intervention group

Active Comparator group

Description:

In the intervention group, a nasotracheal tube is inserted into the nostril with the bevel of the tube facing the cephalad direction of the patient.

Treatment:

Procedure: Bevel facing the cephalad direction of the patient

conventional group

Active Comparator group

Description:

In the conventional group, a nasotracheal tube is inserted in a usual way, i.e., with the bevel of the tube facing the left side of the patient.

Treatment:

Procedure: Bevel facing leftward of the patient
