Ultrasonography Versus Palpation for Identification of the Cricothyroid Membrane

Not Applicable

• Conditions: Airway Obstruction
• Interventions: Procedure: Marking of the cricothyroid membrane after Palpation; Other: Marking the cricothyroid membrane after ultrasound

• Registration Number: NCT02975791
• Lead Sponsor: Rigshospitalet, Denmark

Brief Summary

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. In an obese volunteer

Detailed Description

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.

The purpose is to advise a propriety method for preanesthetic identification. In an obese volunteer

Arm && Interventions

Group	Intervention	Description
palpation	Marking of the cricothyroid membrane after Palpation	Marking the cricothyroid membrane after ultrasound The intervention is to mark the cricothyroid membrane in order to know exactly where it is in case that it should be needed fur emergency cricothyrotomy. The doctors mark the cricothyroid membrane with a pen after using palpation for identification.
