Palpation Versus Ultrasonography for Identifying the Cricothyroid Membrane in Case of a Laterally Deviated Larynx: A Randomized Trial
Primary resultResult — go to the resultRelative risk 21.8 95% CI 3.1–151.0Authors' conclusion
Identification of the cricothyroid membrane in a model of an obese neck with midline deviation of the trachea was more often successful with ultrasound compared to palpation.
