Infrared Transillumination of the Front of the Neck (IRRIS)

Rigshospitalet

Status: Completed

Conditions: Tracheal Intubation

Treatments: Procedure: Tracheal intubation by endoscopy with flexible bronchoscope

Study type: Interventional

Funder types: Other

Identifiers

NCT03930550

H-18038322 IRRIS

Details and patient eligibility

About

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.

Full 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.

24 participants in 2 patient groups

Infrared guidance first

Experimental group

Description:

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

Treatment:

Procedure: Tracheal intubation by endoscopy with flexible bronchoscope

Infrared guidance last

Active Comparator group

Description:

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

Treatment:

Procedure: Tracheal intubation by endoscopy with flexible bronchoscope
