About this trial
This prospective observational study aims to evaluate the relationship between preoperative ultrasonographic airway measurements and the Video-Intubation Difficulty Assessment Classification (VIDIAC) score in adult patients undergoing endotracheal intubation under general anesthesia. The study will investigate whether airway ultrasound parameters can predict difficult videolaryngoscopic intubation and assess their association with the Cormack-Lehane classification, intubation time, and other airway management outcomes.

To evaluate the relationship between preoperative ultrasonographic airway measurements and the VIDIAC score.
The relationship between preoperative ultrasonographic airway measurements and the Videolaryngoscopic Intubation and Difficult Airway Classification (VIDIAC) score will be evaluated in adult patients undergoing videolaryngoscopic intubation. The simplified VIDIAC score classifies patients as easy (-1 or 0), moderate (1), hard (2), or severe (≥3), with higher scores indicating greater videolaryngoscopic intubation difficulty. Correlations between ultrasonographic airway measurements and the VIDIAC score will be analyzed.

Incidence of Difficult Videolaryngoscopic Intubation
The incidence of difficult videolaryngoscopic intubation will be determined using the Videolaryngoscopic Intubation and Difficult Airway Classification (VIDIAC) score. The simplified VIDIAC score is classified as follows: easy (-1 or 0), moderate (1), hard (2), and severe (≥3), with higher scores indicating greater videolaryngoscopic intubation difficulty. Patients classified as having difficult videolaryngoscopic intubation according to the predefined VIDIAC criteria will be identified, and the incidence will be calculated.

Cormack-Lehane Grade
The Cormack-Lehane Grading System will be used to assess the laryngeal view obtained during videolaryngoscopic intubation. The scale ranges from Grade I to Grade IV (minimum: Grade I; maximum: Grade IV), where higher grades indicate poorer laryngeal visualization and greater difficulty with tracheal intubation. The recorded grade will be analyzed for its association with preoperative ultrasonographic airway measurements and the VIDIAC score.
Time frame

Intubation Time
The duration of videolaryngoscopic intubation, measured from insertion of the videolaryngoscope into the oral cavity until successful placement of the endotracheal tube.
Time frame

First-Attempt Intubation Success Rate
The proportion of patients successfully intubated on the first videolaryngoscopic attempt without the need for additional intubation attempts.
