The document discusses a laryngoscope, which is a thin tube with lights and lenses used to examine the larynx (voice box). It describes two main types - the curved Macintosh blade and straight Miller, Wisconsin or Foregger blades. Laryngoscopy can be used to treat vocal cord or throat issues by removing growths or using lasers. The sizes range from 1.3cm blades for infants to 2.5cm for adults over 10 years old. Laryngoscopes are inserted into the side of the mouth and used to sweep the tongue to view the epiglottis and insert an endotracheal tube into the trachea. Complications can include inadequate ventilation, aspiration, hypertension

5. WHAT IS LARYNGOSCOPE?
▪ A laryngoscopy (lair-in-GAHS-kuh-pee) is a test healthcare providers
perform to examine your larynx (voice box).
▪ They perform this test with a laryngoscope, a thin tube with lights,
lens and video cameras that help them to look closely at your larynx.
▪ Laryngoscopes may have tools your provider can use to remove tissue
from your larynx.

6. TYPES OF LARYNGOSCOPE:
▪ 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).

7. LARYNGOSCOPE USED FOR:
▪ Laryngoscopy can be used to treat some problems in the vocal cords
or throat.
▪ For example, long, thin instruments can be passed down the
laryngoscope to remove small growths (tumors or polyps) on the vocal
cords.
▪ A small laser on the end of a laryngoscope can also be used to burn
away abnormal areas.

8. SIZE OF LARYNGOSCOPE:
▪ LARYNGOSCOPE:
An endoscope for visually examining the interior of the larynx.
▪ Size:
The adult size, with a blade that is 2.5 cm wide, is suitable for children
older than 10 years. The pediatric version (newborn to age 2 years) has a
blade 1.3 cm wide that extends 0.6 cm beyond the fiberoptics. This blade
is recommended for use in neonates, infants, and smaller children.

9. SIZES:

10. INSERT LARYNGOSCOPE:
▪ To the left, then the blade is smoothly advanced to the epiglottis. The
laryngoscope is then inserted in the right side of the mouth, and the
blade is then used to sweep the tongue.

11. COMPLICATIONS:
▪ Complications of laryngoscopy include:
▪ Inadequate ventilation
▪ Loss of airway
▪ Aspiration
▪ Hypertension (HTN),
▪ Dysrhythmias
▪ Eye trauma
▪ Dental trauma
▪ Laryngospasm
▪ Bronchospasm
▪ Perforation of the airway or esophagus
▪ Bleeding, Edema, and Airway obstruction.
