  Purpose

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.


Condition
Focus: Localizing the Cricothyroid Membrane Before Airway Management

Study Type: Observational
Study Design: Observational Model: Case-Crossover
Time Perspective: Prospective
Official Title: Comparison of Ultrasound Examination and Palpation to Locate the Cricothyroid Membrane - a Randomized Study

Further study details as provided by Rigshospitalet, Denmark:

Primary Outcome Measures:
  • rate of success of localizing the cricothyroid membrane with ultrasound and palpation [ Time Frame: december 2012 ] [ Designated as safety issue: No ]
    the rate of success is measured


Secondary Outcome Measures:
  • time to localise the cricothyroid membrane with ultrasonography and palpation [ Time Frame: december 2012 ] [ Designated as safety issue: No ]
    time measure for both ultrasonographic and palpation method


Estimated Enrollment: 44
Study Start Date: November 2012
Study Completion Date: December 2012
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts
Palpation
The group using palpation as primary attempt at localizing the cricothyroid membrane
Ultrasonography
The group using ultrasound for their primary approach to localizing the cricothyroid membrane

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.
