Palpation Versus TACA- Ultrasonography for Identifying the Cricothyroid Membrane in Case of a Laterally Deviated Larynx

Not Applicable

Not yet recruiting

• Conditions: Airway Management
• Interventions: Diagnostic Test: Ultrasonography with TACA approach; Diagnostic Test: Palpation

• Registration Number: NCT06092229
• Lead Sponsor: Rigshospitalet, Denmark

Brief Summary

test persons, anaesthesiologists will identify the cricothyroid membrane on a silicone model of the neck with either palpation or ultrasonography.

The ultrasonographic method to be used is the Thyroid-Airline-Cricoid-Airline (TACA) approach.

The larynx-model is deviated to one of the sides to simulate a patient with neck pathology

Detailed Description

test persons, anaesthesiologists will identify the cricothyroid membrane on a silicone model of the neck with either palpation or ultrasonography.

The ultrasonographic method to be used is the Thyroid-Airline-Cricoid-Airline (TACA) approach.

The larynx-model is deviated to one of the sides to simulate a patient with neck pathology.

The test persons are randomised to use other palpation or ultrasonography. Al attempts are video-taped
