Comparison of Two Airway Devices in Paediatric Patients With Difficult Airway

If Flexible Intubation Video Endoscope® (FIVE) will be used, the appropriate endotracheal tube is loaded into the bronchoscope and made ready. The number of attempts and duration of successful intubation were recorded by a non-blinded research assistant. The stopwatch was started when the FFB started to pass through the patient's mouth/nose, and as soon as the ventilation of the lungs was confirmed by the end tidal carbon dioxide trace, the stopwatch was stopped and this time was recorded as the successful intubation time. The time between passing FFB through the mouth/nose and obtaining the best glottic view was recorded as the best glottic visualization time. The endotracheal tube passage time was defined as the intubation time minus the best glottic visualization time and recorded. Complications during the procedure were recorded.

If GlideScope® Titanium is to be used, a 50-60° angle is applied with the appropriate stylet, and the appropriate one from 3 pediatric blade sizes is selected according to the clinical experience of the relevant practitioner. The number of attempts and duration of successful intubation were recorded by a non-blinded research assistant. The stopwatch was started as soon as the videolaryngoscope started to pass through the patient's mouth, and the stopwatch was stopped as soon as the ventilation of the lungs was confirmed by the end tidal carbon dioxide trace, and this time was recorded as the successful intubation time. The time between passing the videolaryngoscope through the mouth/nose and obtaining the best glottic view was recorded as the best glottic visualization time. Endotracheal tube transit time was defined as intubation time minus best glottic visualization time and recorded. Complications during the procedure were recorded.
