简要总结
After Institutional Ethical Committee approval, 100 patients will be enrolled ion the study. Patients will be allotted into two groups(Group C for CMAC and Group T for Truview). All the patients will be premeditated with glycopyrrolate 4mcg/kg, midazolam 10mcg/kg , ondansetron 0.15mg/kg, fentanyl 2mg/kg. Patients will be induced with propofol 2mg/kg and neuro muscular blocking agent vecuronium 0.1mg/kg. Patients will be ventilated with oxygen and nitrous oxide (1:1 ratio) and sevoflurane 2% for initial 4mins, followed by ventilation with 100% oxygen for 1 mins before intubation. Manual inline stabilisation will be applied by the investigator to simulate difficult intubation scenario and the patients will be intubated nasotracheally using either of the laryngoscope. Time taken for intubation will be noted. Patients will be followed up for 24hrs post extubation.
