Airway Management, Identification of the Cricothyroid Membrane
Conditions
Keywords
Airway Management, Ultrasound, Palpation, Cricothyroid membrane
Brief summary
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.
Detailed description
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.
Interventions
DIAGNOSTIC_TESTPalpation
Identification of the cricothyroid membrane using PALPATION, a procedure used to prepare for front of neck airway access
DIAGNOSTIC_TESTUltrasound
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

Intervention model description
Randomised to either palpation or ultrasonography The participants are thus randomised to use either palpation or to use ultrasonography to DIAGNOSE the position of the cricothyroid membrane
