Summary

Difficulty in managing the airway is the single most important cause of major anesthesia-related morbidity and mortality. The currently used clinical method of predicting airway difficulty used by anesthetists is limited and not very highly sensitive or specific. Any additional bedside method that increases its specificity and sensitivity would be valuable. This project is designed to study and measure the tongue thickness and oral cavity height by using an ultrasound scan and comparing them with the same measurements obtained by CT scan. These will also be compared to a more complicated measurements used in previous studies to investigate any correlation with the currently used clinical methods. This information will help us decide if ultrasound may help Anesthesiologists assess difficulties in airway management in a more accurate, precise and reliable simpler method.

Conditions

  • Ultrasound Airway Imaging in Determining the Oral Cavity and Tongue Size

Interventions

OTHER

Ultrasound scan

Ultrasound scanning examinations will be performed twice (pre-CT scan and post CT-scan). Each examination will be performed by two observers who are blinded to each other's measured values.Patients will be asked to place a small sip of water (20 mL)in their mouth and keep the mouth open during the imaging. A second ultrasound examination of each patient by the two observers will be performed after the CT-scan.
