Cricothyroid Membrane, Ultrasound
Neck Position and Ultrasound Landmark of Cricothyroid Membrane
Cricothyroid membrane (CTM) localization is a critical step prior to emergent surgical airway access. Ultrasound-guided localization of the CTM on the skin of the neck had been suggested prior to induction of general anesthesia…

Airway Obstruction
Ultrasonography Versus Palpation for Identification of the Cricothyroid Membrane
After a structured teaching program anaesthetists are educated in identifying the cricothyroid membrane with ultrasonography. Thereafter their ability to do so is compared with their ability to do so with palpation.
