Epistaxis, Intubation Complication
Conditions
Keywords
epistaxis
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
Interventions
PROCEDUREBevel facing the cephalad direction of the patient
The bevel of the nasotracheal tube facing cephalad direction of the patient
PROCEDUREBevel facing leftward of the patient
The bevel of the nasotracheal tube facing the left side of the patient

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