Name Time Method Incidence of Difficult Intubation <br/ ><br>Timepoint: Number of difficult tracheal intubations as a percentage (%) among all the cases of tracheal intubations done in the study population using the criteria for difficult intubation. <br/ ><br>Tracheal intubation was classified as difficult if one or more of the criteria was present. <br/ ><br>1)Cormack Lehane classificaton 3-4 <br/ ><br>2)Use of intubating aids like bougie, Frova, Mccoy Laryngoscope, alternative technique of intubation <br/ ><br>3)Laryngoscopy attempts more than 2 <br/ ><br>4)Laryngoscopy time more than 5 minutes <br/ ><br> <br/ ><br> <br/ ><br>
- Secondary Outcome Measures
Name Time Method Evaluate key predictors out of ten for Difficult intubation and its validityTimepoint: Predictive accuracy asessed by calculating sensitivity, specificty, and positive predictive value of each predictor. Independent key predictors for difficult intubation were derived using logistic regression analysis <br/ ><br>
