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.
Two basic styles of laryngoscope blade are currently commercially available: the curved blade and the straight blade. The Macintosh blade is the most widely used of the curved laryngoscope blades, while the Miller blade is the most popular style of straight blade.
Also Know, how do you use a Miller blade? Much like a Mac, you place the blade into the corner of the mouth, and advance it along the groove between the tongue and the tonsil (“paraglossal”). Then, however, things go a little differently.
Similarly, it is asked, how do I know what size laryngoscope blade I need?
II. Preparation: Estimated blade size selection
- With Laryngoscope Blade held next to patient’s face. Blade should reach between lips and Larynx (or lips to angle of jaw)
- Better to choose a blade too long than too short. Estimate 1 cm longer than needed.
- Video Laryngoscopy Blade (e.g. Glidescope)
What is a laryngoscope blade used for?
The anterior commissure laryngoscope is frequently used by otolaryngologists for visualization of the glottis. It is a rigid, tubular, straight-blade laryngoscope with a distally located, recessed light source. This design permits enhanced visualization by preventing the tongue from obscuring the field of view.
Why do we use laryngoscope?
Doctors sometimes use a small device to look into your throat and larynx, or voice box. This procedure is called laryngoscopy. They may do this to figure out why you have a cough or sore throat, to find and remove something that’s stuck in there, or to take samples of your tissue to look at later.
How many types of laryngoscope are there?
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. Indirect Laryngoscopy: Insertion of the endotracheal tube by a method of indirectly visualizing the vocal cord, either using a video camera or optics (mirrors).
How do you sterilize a laryngoscope blade?
Place cleaned blades in, hospital approved, high–level disinfectant solution that is prepared and maintained according to manufacturer’s recommendation. Set the timer for 8 minutes per manufactures recommendations to allow for blade exposure. Thoroughly rinse blades by fully immersing in potable water.
How does a laryngoscope work?
A laryngoscopy is an exam that gives your doctor a close-up view of your larynx and throat. Air passing through your larynx and over the vocal folds causes them to vibrate and produce sound. This gives you the ability to speak. A specialist known as an “ear, nose, and throat” (ENT) doctor will perform the exam.
Is laryngoscopy painful?
Laryngoscopy is relatively painless, but the idea of having a scope inserted into the throat can be a little scary for kids, so it helps to understand how a laryngoscopy is done.
What is DL Scopy?
Direct laryngoscopy is a procedure to examine the larynx. You may have problems with your voice, swallowing, or breathing. A microscope and/or laser is used to do a detailed examination of all the parts of your larynx, including your vocal cords.
What size laryngoscope blade should be used to intubate a newborn?
A laryngoscope with a straight blade (size 1 [10 cm] for term infants and larger pre term infants, size 0 [7.5 cm] for premature infants < 32 w or 00 [6cm] for extremely low birth weight infants) is preferred. Some experienced operators use curved blades.
Who invented the GlideScope?

Why is a straight laryngoscope blade recommended for intubating a child?
The straight Miller laryngoscope blade is traditionally recommended for intubation in infants, due to the large size and flexibility of the infant epiglottis. Two photographs of the laryngeal view were taken with each blade: one while lifting the epiglottis and one while lifting the tongue base.
