Registered outcomes9
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Percentage of Glottic Opening (POGO) Score in the Sniffing Position Versus the LeHeR Position | During video laryngoscopy, approximately 2-10 minutes after induction of general anesthesia | Percentage (0-100%) of the glottic opening visible from the anterior commissure to the interarytenoid notch during video laryngoscopy; higher values indicate a better view. Each patient is assessed first in the sniffing position and then after 45° left head rotation (LeHeR), and the paired scores are compared within the same patient. |
| Secondary | Fremantle Score | During endotracheal intubation, from first laryngoscopy until confirmed tracheal intubation | Three-part score describing video laryngoscopic intubation: view (full / partial / none), ease (1 = easy, 2 = modified, requiring adjuvant maneuvers or devices, 3 = failed), and device (video laryngoscope type and blade size). |
| Secondary | Number of Intubation Attempts | During endotracheal intubation, from first laryngoscopy until confirmed tracheal intubation | Total number of laryngoscopy attempts required for successful endotracheal intubation. |
| Secondary | Intubation Time | During endotracheal intubation, from first laryngoscopy until confirmed tracheal intubation | Time in seconds from passage of the video laryngoscope blade between the lips to the appearance of the first end-tidal carbon dioxide waveform on capnography. |
| Secondary | Number of Participants Requiring Adjuvant Maneuvers or Devices | During endotracheal intubation, from first laryngoscopy until confirmed tracheal intubation | Number of participants requiring BURP, external laryngeal manipulation, stylet or bougie, cuff inflation/deflation, or return of the head to the sniffing position to achieve intubation. |
| Secondary | Number of Participants With Airway Trauma | From first laryngoscopy until 5 minutes after intubation | Number of participants with signs of airway trauma, defined as blood on the video laryngoscope blade or endotracheal tube, or lip, dental or oropharyngeal mucosal injury. |
| Secondary | Heart Rate | Baseline (before induction), after induction, and at 1, 3 and 5 minutes after intubation | Heart rate (beats/min) |
| Secondary | Mean arterial pressure | Baseline (before induction), after induction, and at 1, 3, 5 and 10 minutes after intubation | Mean arterial pressure (mmHg) |
| Secondary | Peripheral Oxygen Saturation | Baseline (before induction), after induction, and at 1, 3, 5 and 10 minutes after intubation | Peripheral Oxygen Saturation (sPO2) |
