Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| number of the patients with successful nasotracheal intubation and scoring difficult intubation scale | half an hour | Nasotracheal intubation assisted by a video-stylet may be performed in patients undergoing oro-maxillo-facial surgery following induction of anesthesia (fentanyl 2 micro-gram/kg, thiamylal 5 mg/kg, cis-atracurium 0.2 mg/kg and propofol 1 mg/kg) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| time to intubate | 10 minutes | time of Intubating the nasotracheal tube (NT) from selected nostril to trachea is continuously calculated but separately into two parts. part one: from termination of mask ventilation and mask removed from face, to the NT tip on the nasopharynx. part two: advancing NT from nasopharynx, through vocal cord into trachea, to present of 3 end tidal carbon dioxide waveforms. |
Other
| Measure | Time frame | Description |
|---|---|---|
| postoperative nasal bleeding, sore throat and hoarseness | 2 days | Events of intubating related nasal bleeding are recorded on selected nostril and oral cavity at 3 minutes post-intubation and post-operatively. Incidences of sore throat and hoarseness are evaluated before patients out of recovery room and the following morning |
