Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Video laryngoscopy
-The video laryngoscope is a device used during the induction of anesthesia to assist with endotracheal intubation. It consists of a handle with a screen and a blade. During intubation, the video laryngoscope blade is inserted into the patient's mouth to visualize the glottis and vocal cords on the screen. This visualization helps guide the endotracheal tube into the trachea.
-It is typically a one-time process per intubation attempt. The procedure duration can vary but generally takes about 30 seconds to a minute.
-To make this study pragmatic and feasible, intubations can be performed by either a consultant anaesthetist or by trainees who are supervised by a consultant anaesthetist.
-Adherence to proper technique and use of video laryngoscope is monitored through procedural documentation.

Comparator / control treatment
Direct laryngoscope
- The direct laryngoscope is a traditional device used during the induction of anesthesia for endotracheal intubation. It consists of a handle and a blade. Unlike the video laryngoscope, which relies on a camera and screen for visualization, the direct laryngoscope provides a direct line of sight.
-The direct laryngoscope procedure is typically a one-time process per intubation attempt and can take about 30 seconds to a minute.
-To make this study pragmatic and feasible, intubations can be performed by either a consultant anaesthetist or by trainees who are supervised by a consultant anaesthetist.
-Adherence to proper technique and use of video laryngoscope is monitored through procedural documentation.
