Effect of Continuous Supraglottic Oxygen Insufflation Via Video Laryngoscope Blade on Apneic Oxygenation During Tracheal Intubation Under General Anesthesia

Starting soon · Not applicable

Conditions studied: Apneic Oxygenation

In brief

This study is a prospective, randomized controlled clinical trial aimed at investigating the efficacy and safety of a novel oxygenating video laryngoscope blade during apneic oxygenation for intubation under general anesthesia. Hypoxemia is prone to occur during anesthesia induction, which can lead to severe complications. Apneic oxygenation is an important method to prolong the safe apnea time, but existing oxygen delivery modalities have limitations in applicability. Although the laryngeal oxygen delivery approach combined with video laryngoscopy has theoretical advantages, clinical evidence is insufficient. Therefore, this study was conducted.
