研究概览
简要总结
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.
详细描述
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.

结局指标
主要结局
Fraction of cases where the blinking light is seen before the vocal cords are seen
时间窗: 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 -
次要结局
- 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)
- Time from the tip of the flexible scope passes the teeth until vocal cords are seen(1 day of the procedure)
