Rigshospitalet

Status: Completed

Conditions: Identification of the Cricothyroid Membrane; Airway Management

Treatments: Diagnostic Test: Palpation; Diagnostic Test: Ultrasound

Study type: Interventional

Funder types: Other

Identifiers

NCT06701864

Details and patient eligibility

About

Participants will be anesthesiologists, who will identify the cricothyroid membrane on a silicone model of the neck with either palpation or ultrasonography.

The participants can choose either the "String of pearls" or Thyroid-Airline-Cricoid-Airline (TACA) for the ultrasonographic method to be used .

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