简要总结
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.
详细描述
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.

结局指标
主要结局
To evaluate the relationship between preoperative ultrasonographic airway measurements and the VIDIAC score.
时间窗: During videolaryngoscopic intubation
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.
