HYPOXIA
When managing the airway of patients with difficult airways, all three devices can be used to achieve high intubation success rates, but the video stylet and flexible videoscope provide a better view of the vocal cords and are superior to the video laryngoscope in terms of the first-pass intubation success rate. The use of a video stylet has the advantage of a relatively shorter intubation time, allowing successful intubation in a shorter time and reducing the patient’s hypoxia time. Therefore, when anesthesiologists faced with a difficult airway, a video stylet should be the first choice, and if the airway is still not under control, a flexible videoscope should be used.
