Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Infrared guidance first

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

Group Type EXPERIMENTAL

Tracheal intubation by endoscopy with flexible bronchoscope

Intervention Type PROCEDURE

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

Infrared guidance last

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

Group Type ACTIVE_COMPARATOR

Tracheal intubation by endoscopy with flexible bronchoscope

Intervention Type PROCEDURE

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
