NCT07626905

Brief Summary

This study is a single-center, prospective, randomized interventional clinical trial designed to evaluate the effect of the jaw thrust maneuver on glottic visualization, tracheal tube delivery, and overall intubation characteristics during videolaryngoscopic intubation under general anesthesia.

Outcome Measures

Primary Outcomes (1)

  • Need for additional maneuvers for tracheal tube advancement

    Requirement for additional maneuvers to advance the endotracheal tube into the trachea after glottic entry will be recorded. Additional maneuvers are defined as any maneuver required to facilitate tracheal tube advancement after glottic entry, including tube rotation, tube withdrawal and re-advancement, blade repositioning, or external laryngeal manipulation.

    During videolaryngoscopy using a McGrath videolaryngoscope

Secondary Outcomes (8)

  • Operator-rated difficulty of tracheal tube advancement

    During videolaryngoscopy

  • POGO (percentage of glottic opening)

    During videolaryngoscopy

  • Intubation time

    During videolaryngoscopy

  • modified intubation difficulty scale

    During videolaryngoscopy

  • Occurrence of dental contact with the laryngoscope blade

    During videolaryngoscopy

  • +3 more secondary outcomes
