Video-intuboscopy gives a video display of the view from the tip of the tracheal tube during conventional laryngoscopy, and was developed particularly to assist the immediate management of unexpected difficult intubation. A lightweight, malleable video-optical intubation stylet transmits the view from the stylet tip onto a monitor. It is inserted in the tracheal tube before starting anaesthesia, and the view from the tracheal tube tip enables the anaesthetist to verify tracheal tube position in the trachea. During difficult intubation the video view is used to guide the tracheal tube into the trachea. When used to allow confirmation of tracheal placement, the system did not interfere with conventional intubation procedures. The method showed the subglottic airway, gave immediate confirmation of tracheal tube position, and aided teaching and supervision. The method was used to guide intubation in two patients with unanticipated grade 3 laryngoscopic views. Intubation was simple, rapid and atraumatic, without the need for head, neck or laryngeal manipulation. Tracheal placement was instantly confirmed using the video view from the stylet tip. Clinical studies are required to define the value of this new intubation technique.
视频喉镜检查可在传统喉镜检查过程中显示气管导管尖端的视野，其开发的目的尤其在于协助处理意外的困难插管。一种轻巧、可塑形的视频光学插管探条将探条尖端的视野传输到监视器上。在开始麻醉前将其插入气管导管，气管导管尖端的视野能让麻醉医生确认气管导管在气管内的位置。在困难插管时，视频视野用于引导气管导管进入气管。当用于确认气管插管位置时，该系统不会干扰传统的插管操作。该方法显示了声门下气道，能立即确认气管导管位置，并有助于教学和监督。该方法用于指导两名喉镜视野意外为3级的患者进行插管。插管操作简单、迅速且无创，无需对头、颈或喉部进行操作。使用探条尖端的视频视野可立即确认气管插管位置。需要进行临床研究来确定这种新插管技术的价值。
