Validity of ultrasonography in predicting difficult laryngoscopy and confirming endotracheal intubation in obese emergency surgical patients

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.

Inclusion Criteria:

• Adult obese patients (BMI>35) of both sex aged from 18 to 60 years undergoing urgent surgeries under general anasthesia with tracheal intubation.

Exclusion Criteria:

• . Patients with removable upper dentures, upper airway pathology, cervical spine fractures, full stomach, maxillofacial trauma or unstable patients and pregnant women will be excluded from the study
