About

Since the introduction of real-time ultrasound (US) capabilities, ultrasound technology has been adopted and incorporated into daily practice by many medical and surgical specialties. Using US to help assess the difficult airway constitutes just yet another valuable application of this versatile technology . Since many anesthesia providers had already acquired proficiency in US techniques in US guided vascular access and regional nerve blocks, using US to evaluate the airway could be learned and mastered without too much difficulty. Ultrasound of the upper airway may prove to become a useful adjunct to conventional clinical assessment tools, as it has been successful in visualizing the relevant anatomy and critical structures of the airway..

Full description

The study is cross sectional observational study in which obese patients will be assessed using conventional clinical methods of airway assessment and by using US for the same patient before induction of anesthesia then correlated to the Cormack-Lehane finding after induction of anesthesia..

Enrollment: 78 estimated patients
