简要总结
This prospective observational study aims to evaluate whether upper airway ultrasound measurements can improve the prediction of difficult airway compared with conventional anthropometric assessments. Adult patients undergoing elective procedures requiring airway management will be included. Ultrasound parameters such as tongue thickness, anterior neck soft tissue thickness, and hyomental distance will be measured before airway intervention. Standard clinical predictors (Mallampati score, thyromental distance, neck circumference, etc.) will also be recorded. The primary objective is to determine the diagnostic accuracy of ultrasound-based measurements in predicting difficult laryngoscopy and intubation. The study seeks to provide evidence supporting the integration of upper airway ultrasound into routine pre-anesthetic airway evaluation.

研究组 & 干预措施
Single Cohort
This cohort includes all adult participants undergoing airway evaluation with upper airway ultrasound and standard anthropometric measurements. No interventions are applied; participants are observed prospectively to assess the predictive value of ultrasound parameters for difficult airway.
结局指标
主要结局
Diagnostic accuracy of ultrasound airway measurements for predicting difficult mask ventilation
时间窗: Preoperative assessment (within 1 hour before induction of anesthesia)
Evaluation of the sensitivity, specificity, and area under the ROC curve (AUC) of ultrasound-based airway measurements-tongue thickness, hyoid-to-skin distance, and epiglottis-to-skin distance-in predicting difficult mask ventilation. These ultrasound parameters will be compared with conventional anthropometric airway assessment tests to determine their predictive performance.
