Intubation
Conditions
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.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Need for additional maneuvers for tracheal tube advancement | During videolaryngoscopy using a McGrath videolaryngoscope | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Operator-rated difficulty of tracheal tube advancement | During videolaryngoscopy | 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). |
| POGO (percentage of glottic opening) | During videolaryngoscopy | POGO (percentage of glottic opening, from 0% to 100%) is recorded. |
| Intubation time | During videolaryngoscopy | Intubation time is defined as time from laryngoscope insertion into the oral cavity to first EtCO₂ detection |
| modified intubation difficulty scale | During videolaryngoscopy | 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. |
| Occurrence of dental contact with the laryngoscope blade | During videolaryngoscopy | Dental contact was defined as contact between the laryngoscope blade and the patient's teeth during videolaryngoscopy. |
| Occurrence of palatopharyngeal mucosal injury. | After completion of tracheal intubation | Palatopharyngeal mucosal injury in the soft palate and oropharynx is evaluated using a video laryngoscope. |
| Need for lifting force or laryngeal pressure for laryngeal exposure | During videolaryngoscopy | Need for lifting force or laryngeal pressure for laryngeal exposure is recorded. |
| Need for lifting force or laryngeal pressure for advancement of the tube into the glottis | During videolaryngoscopy | need for lifting force or laryngeal pressure for advancement of the tube into the glottis is recorded. |
