Identification of Airway Structures Necessary for Airway Access Via the Skin

NCT02613429 | Completed

• 1 other identifier: Seventh floor 15/1
• Study Type: interventional
• Target: 42
• Locations: 1 country
• Sites: 2

Brief Summary

Literature shows that anaesthetists have a low success-rate when trying to access the airway percutaneously in case of failed ventilation and intubation. The study will investigate anaesthetists ability to locate the trachea and the thyroid cartilage and the cricoid cartilage in patients, using different methods including application of ultrasonography.

Conditions

Upper Airway Obstruction

Outcome Measures

Primary Outcomes (1)

• time to identify the structures necessary for percutaneous airway acess

  two minutes after initiation of the attempt to identify the airway structures

Study Arms (2)

Cranial horizontal

ACTIVE COMPARATOR

identification of the airway by from the cranial end. Marking of the airway, including the cricothyroid membrane, on the skin, by starting the examination from the cranial end at the level of the thyroid catilage , horizontally and thereafter moving caudally

Behavioral: identification of the airway by from the cranial end

caudal longitudinal

ACTIVE COMPARATOR

identification of the airway from the distal end. Marking of the airway, including the cricothyroid membrane, on the skin, by starting the examination caudally, and then moving cranially

Behavioral: identification of the airway from the distal end

Interventions

identification of the airway by from the cranial end BEHAVIORAL

The airway is identified with inspection and imaging technique (ultrasound) by placing the ultrasound transducer over the thyroid cartilage and from there moving distally

Cranial horizontal

identification of the airway from the distal end BEHAVIORAL

The airway is identified with inspection and imaging technique (ultrasound) by placing the ultrasound transducer over the distal trachea and moving cranially

caudal longitudinal
