Exclusion criteria
* history of gastroesophageal reflux disease (GERD) * congenital or acquired abnormalities of the upper airway such as tumor, polyp, trauma, abscess, inflammation, infection, or foreign bodies * previous airway surgery; increased risk of aspiration * coagulation disorders * previous history of difficult intubation or conditions with expected difficult airway including Mallampati classification ≥ 3 or thyromental distance \< 6.5 cm * Using the other intubation devices beyond the direct laryngoscopy such as lighted stylet or fiberoptic bronchoscopy * symptoms of sore throat or upper respiratory tract infection * expected to place nasogastric tube during perioperative period * requiring nasotracheal intubation
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| incidence of postoperative sore throat (POST) | until one day after surgery | ask patients whether they have sore throat after surgery |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Oropharyngeal injury | 2 hours and 24 hours after surgery | assessed by direct visualization of the oropharyngeal cavity with regard to the location such as pharyngeal wall, uvula, vallecular, tonsillar fossa and pillars and presence of hyperemia, edema, hematoma, or any other lesions |
| respiratory symptoms | 1 week after the surgery | At the 1 week postoperative follow-up phone call, patients would be asked if they have upper respiratory symptoms such as cough, sputum, sore throat or fever. And if so, they would be checked if they diagnosed following diseases, common cold, tonsillitis, pneumonia or any other possible respiratory infectious diseases. |
| severity of postoperative sore throat (POST) | When arriving at postanesthesia care unit (PACU) and thereafter 2, 4, and 24 hours after the surgery | The severity of POST was evaluated on a 4-point-scale : 0, no sore throat; 1, mild sore throat (complained of sore throat only upon inquiry); 2, moderate sore throat (complained of sore throat on his/her own); 3, severe sore throat (change of voice or hoarseness, associated with throat pain) |
