Brief summary
either uses a bougie or nasogastric tube to assist the nasotracheal tube passing the nasal cavity, nasopharynx, oropharynx and advanced into the trachea
Detailed description
In oro-maxillo-facial surgery, it is a common practice for patients receiving general anesthesia with nasotracheal intubation to widen the surgical field and to ease undergoing surgery. However, a nasotracheal tube blindly passing through the nasal cavity may easily result in nasal cavity and oropharynx damages. In addition, the advancement of the tube from oropharynx into trachea may assist by either using magic forceps or cuff inflation technique. The aim of the study is to investigate either use a bougie or nasogastric tube to assist the nasotracheal tube passing the nasal cavity, nasopharynx, oropharynx, and advanced into the trachea. Patients were randomized into three groups by using either bougie or nasogastric tube to facilitate nasotracheal tube sliding through into trachea from assigned nostril and compared with the control group with a conventional technique. Hemodynamic changes in each time interval, each time taken of tube going through the nasal cavity, tube advanced from oropharynx into trachea were recorded. The incidence of using Magill Forceps to accurately place tube tip into trachea, intubation related side effects and complications were recorded at postoperative time stages.
Interventions
DEVICEbougie
The endotracheal tube is used in the bougie mode under the direct view of the electronic imaging laryngoscope.
DEVICENasogastric(NG) tube
The endotracheal tube is used in the NG tube mode under the direct view of the electronic imaging laryngoscope.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| success rate of tube advancement and successful first tube attempt | 10 minutes | success rate of tube passing through nasal cavity into trachea |
| time taken in tube advancement | 10 minutes | time taken in tube advancement from nostril into trachea in each time interval |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| post-intubation induced hoarseness and sore throat | 2 days | A visiting questionnaire is used to measure the condition of post-intubation, including sore throat, hoarseness, dysphagia, nasal occlusion, nosebleed and nasal pain. The score for the measurement of sore throat, hoarseness, dysphagia is divided into four degrees: none, mild, moderate and severe; on the other hand, The score for the measurement of nasal occlusion, nosebleed and nasal pain is divided into yes or no. All the evaluation will be assessed in the next coming morning after the postoperation. |
