About this trial
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.

Trial outcomes
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.
Time frame
During videolaryngoscopy using a McGrath videolaryngoscopeSecondary outcomes
1
Operator-rated difficulty of tracheal tube advancement
The operator rates the subjective difficulty of advancing the endotracheal tube into the trachea using a 10-cm visual analogue scale (0 = extremely easy, 10 = extremely difficult).
Time frame
During videolaryngoscopy2
POGO (percentage of glottic opening)
POGO (percentage of glottic opening, from 0% to 100%) is recorded.
Time frame
During videolaryngoscopy3
Intubation time
Intubation time is defined as time from laryngoscope insertion into the oral cavity to first EtCO₂ detection
Time frame
During videolaryngoscopy4
modified intubation difficulty scale
The mIDS score is evaluated based on parameters such as the number of intubation attempts, number of operators, number of alternative intubation techniques, POGO score, requirement for lifting force or laryngeal pressure, and position of the vocal cords during intubation. The score ranges from 0 to 17. Higher scores mean difficult intubation.
