Ultrasonographic Airway Assessment and VIDIAC Score

2. juli 2026 opdateret af: Samsun University

Evaluation of the Relationship Between Ultrasonographic Airway Measurements, Videolaryngoscopic Intubation Findings, and the Video Intubation Difficulty Assessment Classification (VIDIAC) Score in Adult Patients: A Prospective Observational Study

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.

Detaljeret beskrivelse

Difficult airway management is a major cause of anesthesia-related morbidity and mortality. Airway ultrasonography has emerged as a noninvasive tool for evaluating airway anatomy and may help predict difficult intubation. The Video-Intubation Difficulty Assessment Classification (VIDIAC) score is a recently developed and standardized method for assessing videolaryngoscopic intubation difficulty.

This prospective, observational, single-center study aims to evaluate the relationship between preoperative ultrasonographic airway measurements and the VIDIAC score in adult patients undergoing elective surgery under general anesthesia. Ultrasonographic measurements, including tongue depth, tongue thickness, hyomental distance, hyoid depth, hyoid width, and distance from skin to epiglottis, will be obtained before anesthesia induction.

Videolaryngoscopic intubation will be performed by anesthesiologists blinded to the ultrasound findings, and the VIDIAC score will be recorded. The study will assess the correlation between ultrasonographic airway measurements and the VIDIAC score, as well as the ability of these measurements to predict difficult videolaryngoscopic intubation.

Foranstaltningsbeskrivelse
Tidsramme
Incidence of Difficult Videolaryngoscopic Intubation
Tidsramme: During videolaryngoscopic intubation
The incidence of difficult videolaryngoscopic intubation will be recorded and analyzed according to the VIDIAC score. Patients meeting the predefined criteria for difficult videolaryngoscopic intubation will be identified, and the frequency of difficult intubation will be calculated.
During videolaryngoscopic intubation
Cormack-Lehane Grade
Tidsramme: During videolaryngoscopic intubation
The Cormack-Lehane grade obtained during videolaryngoscopic intubation will be recorded and analyzed to evaluate its relationship with preoperative ultrasonographic airway measurements and the VIDIAC score.
During videolaryngoscopic intubation
Intubation Time
Tidsramme: During videolaryngoscopic intubation
The duration of videolaryngoscopic intubation, measured from insertion of the videolaryngoscope into the oral cavity until successful placement of the endotracheal tube.
During videolaryngoscopic intubation
First-Attempt Intubation Success Rate
Tidsramme: During videolaryngoscopic intubation
The proportion of patients successfully intubated on the first videolaryngoscopic attempt without the need for additional intubation attempts.
During videolaryngoscopic intubation
Requirement for Additional Airway Maneuvers
Tidsramme: During videolaryngoscopic intubation
The need for additional airway maneuvers during videolaryngoscopic intubation, including external laryngeal manipulation, repositioning, use of a bougie, stylet adjustment, or other adjunctive techniques to facilitate successful intubation.
During videolaryngoscopic intubation
Occurrence of Oxygen Desaturation
Tidsramme: During videolaryngoscopic intubation
The occurrence of oxygen desaturation during videolaryngoscopic intubation, defined as a decrease in peripheral oxygen saturation (SpO₂) below 90%.
During videolaryngoscopic intubation
Number of Intubation Attempts
Tidsramme: During videolaryngoscopic intubation
The total number of videolaryngoscopic intubation attempts required to achieve successful endotracheal intubation. An intubation attempt is defined as insertion of the videolaryngoscope into the oral cavity with the intention of placing the endotracheal tube.
