Arms & Interventions
conventional laryngoscopy
experimental conventional laryngoscopy group: laryngoscope is used to assist for nasotracheal intubation.
Intervention: conventional laryngoscopy (Device)
video-stylet
experimental video-stylet group:video-stylet is used to guide nasotracheal tube into trachea
Intervention: video-stylet (Device)
Outcomes
Primary Outcomes
number of the patients with successful nasotracheal intubation and scoring difficult intubation scale
Time Frame: 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 Outcomes
- time to intubate(10 minutes)
