Outcomes
Primary Outcomes
number of the patients with successful nasotracheal intubation and scoring modified intubation difficulty scale
Time Frame: half an hour
Nasotracheal intubation is assisted by a video-stylet may be performed in patients undergoing Limited Mouth Opening following induction of anesthesia (fentanyl 2 micro-gram/kg, thiamylal 5 mg/kg) and is facilitated by cis-atracurium 0.2 mg/kg administration. propofol 1 mg/kg intravenously to blunt hemodynamic responses while intubation. a modified intubation difficulty scale to evaluate the difficulty of fiber-scope guided or trachway assisted nasotracheal intubation
Secondary Outcomes
- time to intubate(half an hour)
