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

NCT05679128 | Unknown

• 1 other identifier: Devtrach1
• Study Type: interventional
• Target: 60
• Locations: 0 countries
• Sites: N/A

Brief Summary

test persons, anaesthesiologists will identify the cricothyroid membrane on a silicone model of the neck with either palpation or ultrasonography. The larynx-model is deviated to one of the sides to simulate a patient with neck pathology

Conditions

Airway Management

Outcome Measures

Primary Outcomes (1)

• Correct identification of the cricothyroid membrane within a minute

  The fraction of identifications of the location of the cricothyroid membrane made by the participants, that is actually correct. ie the succesrate of correct identification.

  1 minute

Secondary Outcomes (1)

• Time taken to identification of the estimated location of the cricothyroid membrane.

  up to 3 minutes

Study Arms (2)

palpation

ACTIVE COMPARATOR

digital palpation used to identify the cricothyroid membrane

Diagnostic Test: identification of the cricothyroid membrane using Palpation

ultrasonography

EXPERIMENTAL

Ultrasonography used to identify the cricothyroid membrane

Diagnostic Test: Identification of the cricothyroid membrane using ultrasonography

Interventions

identification of the cricothyroid membrane using Palpation DIAGNOSTIC_TEST

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

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: NONE
• Purpose: DIAGNOSTIC
• Intervention Model: PARALLEL
• Sponsor Type: OTHER

• PI Title: Head of Airway Management development, Consultant anaesthesiologist

Model Details: randomised to either "palpation" or "ultrasonography" The participants are thus arandomised to use either "palpation" or to use "ultrasonography" to DIAGNOSE the position of the cricothyroid membrane
