sonographic evaluation airway

Details and patient eligibility

About

the aim of this study was to evaluate the accuracy of different ultrasonographic parameters and clinical tests to predict difficult airway assessment.

Ultrasonographic parameters were: hyo-mental distence, tongue width, skin to epiglottis distence and skin to hyoid bone distence. these parameters were recorded and their predictive acurracy was studied.

Ultrasonographic parameters were: hyo-mental distence, tongue width, skin to epiglottis distence and skin to hyoid bone distence. these parameters were recorded and their predictive acurracy was studied.

This study analyzed a sample size of 200 patients undergoing elective or urgent surgery under general anesthesia and recieving neuromuscular blocking agent before laryngoscopy.

the correlation between ultrasonographic parameters and difficult laryngoscopy was studied
