To clarify, residents will have only one attempt opportunity each for direct laryngoscopy and in-direct video assisted laryngoscopy. If, after the first unsuccessful attempt, the attending anesthesiologist will take one more attempt respectively for the direct and in-direct views. Between laryngoscopy attempts, the intubator will achieve easy patient ventilation before the next attempt is made. The number of attempts (maximum 4 total) measured as either the reinsertion of the blade or endotracheal tube) and the intubation time (time the laryngoscope blade enters the mouth until 1st capnograph breath) will also be recorded. If unsuccessful, the direct laryngoscopy/ flexible fibreoptic laryngoscopy will be performed to intubate the trachea. If more than 4 attempts (two maximum for each type of laryngoscopy) were needed or if the anesthesiologist discontinued use of the video laryngoscope, the case will be deemed a failure. The subjective level of difficulty (from 0 = Extremely Easy to 5 = Extremely Difficult) in the performance of intubation will also be recorded.
