Design outcomes

Primary

MeasureTime frame
The primary outcome is the time to intubation. This is defined as the time from gripping the laryngoscope until registration of three waves of expired CO2. TTI will be measured in seconds using a stopwatch. In case of repeated attempts, the stop watch will continue to run until successful endotracheal intubation is confirmed.Timepoint: End of intubation.—

Secondary

MeasureTime frame
1.Rate of successful intubation: 2.Number of attempts needed for successful intubation 3.Need for use of optimisation manoeuvres (BURP) 4.The Cormack and Lehane grade at laryngoscopy 5.Percentage of difficult intubations in each group: 6.The occurrence of complications (visible trauma to lip or oral mucosa or blood on the laryngoscope). Timepoint: End of intubation.—
