What is the commonly used laryngoscope?

curved Macintosh blade
The most common laryngoscope blade used for intubation in adults is the curved Macintosh blade (Figure 34-4). This is inserted into the right side of the mouth to displace the tongue laterally. The tip of the blade sits in the vallecula and is lifted forward to elevate the epiglottis and expose the laryngeal inlet.

What are two types of laryngoscope blades?

The laryngoscope blade’s design has many forms, and the two most commonly used blades are the Macintosh and Miller blades, which are curved and straight, respectively. The Macintosh blade is easier to operate, while the Miller blade provides a better view of the vocal cords.

What is the difference between direct and indirect laryngoscopy?

Direct Laryngoscopy: Insertion of the endotracheal tube by a method of directly visualizing the vocal cords. Examples: Macinotosh blade, Miller Blade. Indirect Laryngoscopy: Insertion of the endotracheal tube by a method of indirectly visualizing the vocal cord, either using a video camera or optics (mirrors).

Which laryngoscope is used for pediatrics?

Flexible laryngoscopy: The doctor uses a flexible laryngoscope (a thin, flexible instrument that lights and magnifies images) for a better view of the larynx and vocal cords. Often, doctors can do this in the office after giving a child numbing medicine.

What are the parts of laryngoscope?

The laryngoscope blade itself consists of 3 components: a spatula, which passes over the lingual surface of the tongue; a flange, which is used to direct or displace the tongue; and a tip, which is designed to lift the epiglottis either directly or indirectly (Fig.

What is a Miller blade?

The Miller laryngoscope is a straight blade designed to obtain a view of the vocal cords by directly lifting the epiglottis. It has useful application in ‘floppy’ airways making it popular within paediatric anaesthesia. The Miller laryngoscope is the most commonly used blade today.

Why Miller blade is used in pediatrics?

The Miller (straight) laryngoscope blade is regarded as the preferred blade to expose the laryngeal inlet in infants and children during tracheal intubation.

Why is Miller laryngoscope used in children?

The straight Miller laryngoscope blade is traditionally recommended for intubation in infants, due to the large size and flexibility of the infant epiglottis.

Why straight laryngoscope is used in pediatrics?

Throughout the development of curved and straight blades for pediatric use it has been appreciated that, because of the unique upper airway anatomy of the infant and small child, the straight blade laryngoscope is superior in elevating the tongue, removing it from the field of view to facilitate a better visualization …

What is Magill blade?

Ivan Whiteside Magill (1888-1986). Irish-born anaesthetist, responsible for much of the innovation and development of modern anaesthesia. Helped found the Association of Anaesthetists and professional exams in anaesthesia. The blade is U-shaped in cross section. It is the most commonly used straight blade.

What is laryngeal blade?

Laryngoscope blades are used as the primary tool for examination of the interior of the larynx and for placement of an endotracheal tube. Main Feature: The Miller Laryngoscope Blade . . . The most popular of the straight types.

How do I choose a laryngoscope blade?

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.

Who is the father of laryngoscopy?

Dr. Benjamin Guy Babington, inventor of the laryngoscope. Babington presented his laryngoscope to the Hunterian Society in 1829, and published his report in The London Medical Gazette, Volume 3, page 555, London, 1829.
