Diagnostic Accuracy of Ultrasound Measurements of Anterior Neck Soft Tissue in Determining a Difficult Airway.

Context: Airway management in the emergency department is challenging because conventional screening tools cannot be applied. Therefore, a rapid noninvasive means of identifying a difficult airway will be advantageous for emergency physicians.

Aims: The aim of this study is to examine the association between ultrasound measurements of anterior neck soft tissue and difficult airway as judged by the Cormack Lehane grading.
