Palpation Versus Ultrasonography for Identifying the Cricothyroid Membrane of Distorted Neck-anatomy

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.

About this study

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.

The test persons are randomized to use other palpation or ultrasonography. All attempts are video-taped.

Treatment and study plan

Palpation

Diagnostic Test

Identification of the cricothyroid membrane using PALPATION, a procedure used to prepare for front of neck airway access

Ultrasound

Diagnostic Test

Identification of the cricothyroid membrane, using ULTRASONOGRAPHY with either the "String of pearls" or TACA aproach as chosen by the participant , a procedure used to prepare for front of neck airway access

Primary outcomes

  1. Correct identification of the cricothyroid membrane within a minute

    Time frame: Within 1 minute during procedure

    The fraction of correct identifications of the location of the cricothyroid membrane

Secondary outcomes

  1. Correct identification of the sagittal plane within the airway

    Time frame: Within 1 minute during procedure

    The fraction of identifications that were within the sagittal boundaries of the trachea
