What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: During videolaryngoscopy using a McGrath videolaryngoscope
Secondary outcomes (8)
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).
Measured: During videolaryngoscopy
POGO (percentage of glottic opening)
POGO (percentage of glottic opening, from 0% to 100%) is recorded.
Measured: During videolaryngoscopy
Intubation time
Intubation time is defined as time from laryngoscope insertion into the oral cavity to first EtCO₂ detection
Measured: During videolaryngoscopy
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.
Measured: During videolaryngoscopy
Occurrence of dental contact with the laryngoscope blade
Dental contact was defined as contact between the laryngoscope blade and the patient's teeth during videolaryngoscopy.
Measured: During videolaryngoscopy
Occurrence of palatopharyngeal mucosal injury.
Palatopharyngeal mucosal injury in the soft palate and oropharynx is evaluated using a video laryngoscope.
Measured: After completion of tracheal intubation
Need for lifting force or laryngeal pressure for laryngeal exposure
Need for lifting force or laryngeal pressure for laryngeal exposure is recorded.
Measured: During videolaryngoscopy
Need for lifting force or laryngeal pressure for advancement of the tube into the glottis
need for lifting force or laryngeal pressure for advancement of the tube into the glottis is recorded.
Measured: During videolaryngoscopy
