Study & Design

• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Speed of intubation. This will be measured using a stop-watch (seconds) by one of the study investigators who is also an anaesthetist.[At time of intubation, immediately after induction of anaesthesia. Intubation is predicted to take 30-60 seconds.]

Secondary Outcome Measures

Name	Time	Method
Incidence of difficult tracheal intubation. This will be assessed by the anaesthetist performing the intubation. Difficulty of intubation will be assessed via the intubation difficulty score (IDS) which is a validated measure of the difficulty of intubation.[At time of intubation, immediately after induction of anaesthesia.];Laryngoscopic view will be assessed by the established Cormack/Lehane grading system. This grading system applies grades to the view depending on how much of the larynx is seen.[At time of intubation, immediately after induction of anaesthesia.];Incidence of complications will be assessed when one of the study investigators reviews the patient in recovery ie. after they have woken up from surgery.[At the end of the procedure];Success rate of intubation will be calculated by dividing attempts at intubation by successful intubation.[At time of intubation, immediately after induction of anaesthesia.]
