Laryngoscope The laryngoscope (Figure 31-3) is a device designed to assist in the visualization of the trachea during intubation. From: Sedation (Fifth Edition), 2010 Related terms: • Tracheal Intubation • Patient • Intubation • Anesthesiologist • Laryngeal Mask • Endotracheal Tube • Laryngoscopy • Videolaryngoscope Jan-Henrik Schiff, ... Carin A. Hagberg, in Benumof and Hagberg's Airway Management, 2013 2Laryngoscope Modifications and Rigid Optical Instruments Laryngoscopes are designed for visualization of the vocal cords and for placement of the ETT into the trachea under direct vision. The two main types are the curved Macintosh blade and the straight blade (i.e., Miller with a curved tip and Wisconsin or Foregger with a straight tip). All blades are available in different sizes for every age of patients. The main injury caused by using laryngoscopes is damage to the teeth. In cases of inadequate visualization of the vocal cords, a change of the patient's head position may lead to success. In some cases, a blade of inadequate size is responsible for intubation failure. An external laryngeal manipulation (e.g., BURP, OELM) may move the vocal cords into the line of vision and facilitate intubation. Obtaining a view of the vocal cords with a conventional laryngoscope requires optimal positioning of the patient. With a flexible fiberscope, positioning is not an issue, and damage to the teeth is less likely. Similarly, with innovations such as the Glidescope video laryngosc...

Direct laryngoscopy is carried out (usually) with the [ citation needed] Indirect laryngoscopy [ ] Indirect laryngoscopy is performed whenever the provider visualizes the patient's vocal cords by a means other than obtaining a direct line of sight (e.g. a mirror). For the purpose of intubation, this is facilitated by fiberoptic bronchoscopes, video laryngoscopes, fiberoptic stylets and mirror or prism optically enhanced laryngoscopes. [ citation needed] History [ ] Some historians (for example, In 1854, the All previous observations of the glottis and larynx had been performed under indirect vision (using mirrors) until 23 April 1895, when autoscope.
