Infrared Transillumination of the Front of the Neck

Not Applicable
Completed
Conditions
Tracheal Intubation
Interventions
Procedure: Tracheal intubation by endoscopy with flexible bronchoscope
Registration Number
NCT03930550
Lead Sponsor
Rigshospitalet, Denmark
Brief Summary

Infrared light is applied to the front of the neck of patients for awake flexible optical intubation. The infrared light can be detected by the camera at the tip of the flexible video-bronchoscope. The flexible scope is introduced into the trachea with or without the aid of the blinking infra red light and the ease of placement of the flexible scope is studied.

Detailed Description

The investigators study patients for anaesthesia who will need endotracheal intubation and in whom the intubation is predicted to become difficult so that an awake flexible-video-scope-guided intubation is chosen.

Infrared guidance firstTracheal intubation by endoscopy with flexible bronchoscopeIn this arm the infra red guidance is applied to the first passage of the flexible scope to the trachea. The second passage of the flexible scope is without the infrared light
Infrared guidance lastTracheal intubation by endoscopy with flexible bronchoscopeIn this arm NO infra red guidance is applied to the first passage of the flexible scope to the trachea. The second passage of the flexible scope is with the infrared light as guide
Primary Outcome Measures
NameTimeMethod
Fraction of cases where the blinking light is seen before the vocal cords are seen1 day of the procedure

The flexible scope is entered into the airway twice, . It is noted from watching the videos of the procedures if the blinking light or the vocal cords are seen first -

Secondary Outcome Measures
NameTimeMethod
Fraction of cases where the blinking light is seen from the teeth, the mouth, the pharynx and the larynx and the fra fraction of cases where the vocal cords are seen from the teeth, the mouth, the pharynx and the larynx1 day of the procedure

The flexible scope is entered into the airway twice, one time with and one time without the blinking light on the front of the neck. It is noted from watching the videos of the procedures if the blinking light or the vocal cords are seen first - and from which anatomical location it is seen.

Time from the tip of the flexible scope passes the teeth until vocal cords are seen1 day of the procedure

Time measured from the tip of the flexible scope passes the teeth until the vocal cords are seen
