简要总结
Difficult tracheal intubation is considered the most important cause for morbidity and mortality during induction of anesthesia. Recently, video laryngoscopy (VL) has been widely used in cases of difficult intubation as it has shown to produce better visualization of the anatomical airway structures. . The advanced optical system and its light source (high intensity light-emitting diodes) led to a clear view of the vocal cord and enabled the operator to overpass the tip of laryngoscope blade to reach into the vallecula under vision. video stylet possesses the advantages of both rigid and flexible intubation endoscopes . It is composed of rigid unchanneled metal stylet with 4 cm flexible dynamic tip at which there is light source and mini size video camera. It is connected to the monitor screen to display the images on it, giving a direct view of vocal cord and upper tracheal rings and so it helps in cases of anticipated difficult intubation . It can accommodate size 6.0 endotracheal tube or greater.
