Identification of Airway Structures Necessary for Airway Access Via the Skin

Identification of Airway Structures Necessary for Airway Access Via the Skin to be Used in Case of Failure to Maintain Oxygenation With Non-invasive Methods

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.

Study Overview

• Status: Completed
• Conditions: Upper Airway Obstruction
• Intervention / Treatment: Behavioral: identification of the airway by from the cranial end; Behavioral: identification of the airway from the distal end

Detailed Description

Literature shows that anaesthetists have a low success-rate when trying to access the airway percutaneously in case of failed ventilation and intubation.

The researchers will investigate anaesthetists ability to locate the trachea and the thyroid cartilage and the cricoid cartilage of a healthy subject with different methods including application of ultrasonography.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Cranial horizontal; 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; The airway is identified with inspection and imaging technique (ultrasound) by placing the ultrasound transducer over the thyroid cartilage and from there moving distally
Active Comparator: caudal longitudinal; 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; The airway is identified with inspection and imaging technique (ultrasound) by placing the ultrasound transducer over the distal trachea and moving cranially
