What are video laryngoscopes used for?

Videolaryngoscopy is a relatively new technology developed to improve the success rate of tracheal intubation. A high-resolution micro camera mounted on the tip of a curved blade connected to small portable digital monitor improves the view of the vocal cords and subsequently the success rate of direct laryngoscopy.

What are video laryngoscopes?

Video laryngoscopes (VLs) and optical stylets (OS) are rigid devices that allow indirect laryngoscopy, or visualization of the vocal cords and related airway structures without a direct line of sight.

How are laryngoscopes used?

Direct laryngoscopy uses a tube called a laryngoscope. The instrument is placed in the back of your throat. The tube may be flexible or stiff. This procedure allows the doctor to see deeper in the throat and to remove a foreign object or sample tissue for a biopsy.

How is video laryngoscopy done?

Video laryngoscopy is the premise of fiberoptic intubation. Fiberoptic intubation involves threading an endotracheal (ET) tube over the shaft of a flexible fiberoptic scope. The scope is passed through the mouth or the nose of the patient, into the pharynx, and through the vocal folds into the patient’s trachea.

Is video laryngoscopy direct or indirect?

Indirect laryngoscopic methods include rigid fiberoptic laryngoscopy and rigid video laryngoscopy, both of which are potentially useful modalities for management of the difficult airway and may bridge a gap between direct laryngoscopy and other established techniques such as flexible fiberoptic intubation.

What sizes do laryngoscopes come in?

A standard laryngoscope handle or a flexible fiberoptic cable connected to a light source powers the fiberoptic light source. This laryngoscope is manufactured in three sizes: adult, pediatric, and pediatric long. The adult size, with a blade that is 2.5 cm wide, is suitable for children older than 10 years.

Which laryngoscope is most commonly used?

C-MAC laryngoscope
The C-MAC laryngoscope is the most extensively studied of these and is associated with shorter intubation times and greater ease of use, compared with other VLs,234,235 which is possibly due to laryngoscopists’ familiarity with the use of a Macintosh-style blade (Fig. 44.26).

What are the types of laryngoscopes?

The three kinds of laryngoscopy are:

  • indirect laryngoscopy.
  • fiber-optic (flexible) laryngoscopy.
  • direct laryngoscopy.

What is the difference between direct and indirect laryngoscopy?

Direct laryngoscopy is the method currently used for tracheal intubation in children. It occasionally offers unexpectedly poor laryngeal views. Indirect laryngoscopy involves visualizing the vocal cords by means other than obtaining a direct sight, with the potential to improve outcomes.

How do I know my laryngoscope size?

The blade length excluding the base is measured by placing the proximal blade at the child’s upper incisor teeth with the blade tip extending to the angle of the mandible. If the blade tip is within 1 cm proximal or distal to the angle of the mandible, it is an appropriate blade length for intubation.
