Neck Position and Ultrasound Landmark of Cricothyroid Membrane

Canada58 participantsStarted 2018-11-09

Plain-language summary

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 so that a marked entry point can be used to quickly establish emergent front of neck access if required. In this prospective observational study, the investigators aim to determine the potential for migration of the CTM markings in the sagittal plane during neck repositioning.
