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

NCT06701864 | Completed

• 1 other identifier: F-22064259-3
• Study Type: interventional
• Target: 61
• Locations: 1 country
• Sites: 1

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.

Conditions

Identification of the Cricothyroid Membrane; Airway Management

Keywords

Airway Management; Ultrasound; Palpation; Cricothyroid membrane

Outcome Measures

Primary Outcomes (1)

• Correct identification of the cricothyroid membrane within a minute

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

  Within 1 minute during procedure

Secondary Outcomes (1)

• Correct identification of the sagittal plane within the airway

  Within 1 minute during procedure

Study Arms (2)

Palpation

ACTIVE COMPARATOR

digital palpation used to identify the cricothyroid membrane

Diagnostic Test: Palpation

Ultrasound

EXPERIMENTAL

Ultrasonography (either "String of pearls" or TACA approach) used to identify the cricothyroid membrane

Diagnostic Test: Ultrasound

Interventions

Palpation DIAGNOSTIC_TEST

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

Palpation

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

Ultrasound

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: NONE
• Purpose: DIAGNOSTIC
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: Principal investigator

Model Details: 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
