Infrared Transillumination of the Front of the Neck

Rigshospitalet, Denmark24 enrolled

Overview

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.

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.

Interventions

Tracheal intubation by endoscopy with flexible bronchoscopePROCEDURE

A blinking infrared light source is placed on the anterior neck at the level of the cricothyroid membrane to serve as a guide to facilitate finding the way to the trachea

Outcomes

Primary Outcomes

Fraction of cases where the blinking light is seen before the vocal cords are seen

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 -

Time frame: 1 day of the procedure

Secondary Outcomes

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

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 frame: 1 day of the procedure

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

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

Time frame: 1 day of the procedure
