The aim of the study is to determine whether preoperative ultrasound assessment of of the upper airway can predict difficult laryngscopy in emergency surgical obese patients , by analysis correlations between ultrasound measurements of anterior cervical soft in the upper airway, and the Cormack-Lehane grade. And evaluate its role in confirming the endotracheal placement The secondary objective was to determine whether clinical screening tests are independent predictors of difficult airway.
Validity of ultrasonography in predicting difficult laryngoscopy and confirming endotracheal intubation in obese emergency surgical patients
