Study summary

Anesthesiologists get a course on localizing the cricothyroid membrane on a human using ultrasonography. Thereafter their ability to localize the cricothyroid membrane with either palpation or ultrasonography, in a randomised fashion, is tested.

Read the detailed description

The ability to localize the cricothyroid membrane on patients before airway management is crucial in order to be able to follow the difficult airway algorithms.

Studies have show a high failure rate when anesthesiologists rely on palpation.

In this study Anesthesiologists get an e-learning course, get literature to study , and get a theoretical course and a hands-on course in using ultrasound for localizing the cricothyroid membrane. . Thereafter their ability to localize the cricothyroid membrane with either palpation or ultrasonography, in a randomised fashion, is tested.
