The purpose of the study is to investigate the effect of tube rotation on passage of the tracheal tube through the nasopharynx into the oral cavity in nasotracheal intubation.
This prospective randomized controlled study was approved by IRB of our institute.
Patients requiring nasotracheal intubation will be screened for eligibility of the study. Then, patients will be randomized to one of two groups; (group I: tube advancement in neutral / group II: tube advancement with the tube counter-clockwise rotated). After induction of anesthesia and muscle relaxation, the preformed nasal RAE (Ring-Adair-Elwyn) tube will be inserted via a nostril approximately 3-4 cm. Next, an anesthesiologist will advance the tube, with it neutral, continuously into the oral cavity of the patients in Group I, while the anesthesiologist will advance the tube, with it rotated counter-clockwise in 90 degree, into the oral cavity of the patients in Group II. After the tube will be placed in the oral cavity, the anesthesiologist will perform nasotracheal intubation with Magill forceps. After that, an investigator will check occurrence of epistaxis due to nasotracheal intubation and its severity with a fiberoptic bronchoscope. After obtainment of all data, investigators will analyze incidence of epistaxis and its severity between two groups.
| Arm | Type | Interventions | Description |
|---|---|---|---|
| Rotation | Experimental | Procedure: nasotracheal intubation | For nasotracheal intubation, the nasal RAE tube will be inserted with it rotated by 90 degrees in counter-clockwise direction for patients in the 'Rotation' arm. |
| Neutral | Active comparator | Procedure: nasotracheal intubation | For nasotracheal intubation, the nasal RAE tube will be inserted without tube rotation for patients in the 'Neutral' arm. |
