To evaluate the efficacy of a real-time artificial intelligence (AI)-assisted glottic recognition and alignment guide feature in channel-type video laryngoscopy for reducing time to intubation (TTI) among novice operators (resident physicians with 5 or fewer prior human endotracheal intubations).
Secondary objectives include assessing first-pass success rate (FPS), POGO score, frequency of attending physician verbal advice or intervention, and perioperative complications, as well as exploratorily evaluating the impact of AI assistance on the initial learning curve across consecutive intubation attempts.
Safety,Efficacy
Outcome Name: Time to Intubation (TTI)
Definition: Time elapsed (in seconds) from the passage of the video laryngoscope blade through the dental arch until the first ring mark on the endotracheal tube passes between the vocal folds (confirmed by capnography ETCO2 waveform).
Timepoint: During the intubation procedure (each case)
1. First-Pass Success (FPS) Rate: Proportion of successful endotracheal intubation achieved on the first blade insertion without direct physical assistance or manual intervention by the attending physician. [Timepoint: Immediately after each attempt]
2. Percentage of Glottic Opening (POGO) Score: Visualized percentage of the glottic opening . [Timepoint: During the intubation procedure]
3. Frequency of Attending Physician Verbal Advice: Number of standardized verbal cues or instructions provided by the attending physician during the attempt. [Timepoint: During each attempt]
4. Perioperative Complication Rate: Incidence of hypoxemia (SpO2 less than 93 percent), dental injury, oral bleeding, or esophageal intubation. [Timepoint: From the end of intubation until extubation or PACU admission]
5. Learning Curve: Changes in time to intubation (TTI) across consecutive intubation attempts (1st to 6th cases per resident) and the interaction between AI assistance and consecutive attempt order (AI x attempt number). [Timepoint: During data analysis after completion of all cases]

Treatment
| Device,equipment |
Endotracheal intubation is performed using a channel-type video laryngoscope with real-time AI glottic recognition and alignment guide features enabled (ON).
Endotracheal intubation is performed using a channel-type video laryngoscope with AI-assisted features disabled (OFF), displaying standard video laryngoscopy imagery.
