Infrared Transillumination of the Front of the Neck
- 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.

- Arm && Interventions
Group Intervention Description Infrared guidance first Tracheal intubation by endoscopy with flexible bronchoscope In 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 last Tracheal intubation by endoscopy with flexible bronchoscope In 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
Name Time Method Fraction of cases where the blinking light is seen before the vocal cords are seen 1 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
Name Time Method 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 larynx 1 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 seen 1 day of the procedure Time measured from the tip of the flexible scope passes the teeth until the vocal cords are seen
