Laryngoscopes

Types of Layryngoscopes, glideoscopes

QuestionAnswer
What is a Laryngoscope An instrument used to examine the larynx and to facilitate intubation of the trachea.
what are the two main components of a Laryngoscope? Handle and Detachable blade.
what agency is responsible for standards of the fiberoptic laryngoscope? ASTM
Why does the layngoscope handle have a rough gripped handle? helps improve grip
what is the power source for light? batteries
How is the light source energized? when the base and the handle are locked together.
Most blades form a --------- angle with handle when ready for use Right
video laryngoscopy is also know as------- indirect laryngoscopy
what do you call the rigid component inserted into the patients mouth? Blade
blades are metal and reusable. T/F TRUE
Blades are plastic and disposable? t/f TRUE
Light source can be Fiberoptic or Bulb lamp.T/F True
WHat is the main function of the blade? It compresses the tongue and soft tissue into the lower jaw.
What is the purpose of the flange? To deflect soft tissue to improve view of larynx. To push the tongue out of the way.
How many types of laryngoscope blades are there? 2
Name the two major types of laryngoscope blades? Straight and Curved
Name the curved Blade. MAC- Blade
Name 4 modifications to the MAC-Blade 1. Oxiport 2. Fink- Reduced flange hieght 3.Bullard-Guifforda- No Flange 4.Tull- Suction port/channel
What kind of blade will you use on this population of patients-Rheumatoid Arthritis, and TMJ? Bizzari-Guifforda
Describe the vision macintosh Blade It is concave at midpoint of the blade, allowing superior visualization without changing technique.
Upsher low Profile blade is used for patients with a small mouth. It has a low flange and it is a fairly straight blade. T/F True
What is the difference between the Wisconsin and WisHipple Blade? Wisconsin has no curve on end of flange versus the WisHipple which has a larger and straighter flange.
What is unique about the Mccoy Blade? It has a lever with which to move the tip of the blade upward.
What is the advantage of the Mccoy blade? It can be used in patients with decreased cervicalROM,C.spine injuries, limited mouth openings.
When is the Robert Shaw blade used? During nasal intubation.
Is the Robert Shaw blade curved or straight? Straight.
What population of patients do you use the Robert Shaw blade? Infants and children.
The magill forceps are used during nasal intubation. T/F True
Do not clean Laryngoscopes after use. T/F FALSE
What are five complications of direct laryngoscopy Dental injury, cardiovascular response, damage to soft tissues and nerves, malfunctioning of laryngoscope, injury to cervical spine.
Dental Injury as a result of laryngoscope use includes? Damage of upper incisors
Damage of Soft tisuues as a result of laryngoscope use include? Abrasions, Hematomas,lacerations of soft tissues, lingual nerve injury, massive tongue swelling, pharygneal esophageal perforation.
A patient has a cervical apinal injury, how will the SRNA fascilitate laryngoscopy and subsequent intubation safely? The SRNA has several options and will use the MILS, CLM- Blade, Bullard scope, Glideoscope, lightwand and or a Fiberoptic scope
List 6 advantages of using indirect or video laryngoscope. 1. Fasciliting intubation of an awake patient 2.unstable c.spines. 3. Difficult airways 4. Tracheobronchial lavage, removal of foreign body 5. Evaluation of airway anatomy after trauma, burn, angioedema, and prolonged intubation 6.Evaluation of ETT p
What type of nerve blocks are performed for a fiberoptic intubation? Name 3. Trans-tracheal block, Superior laryngeal nerve block, and glossopharyngeal nerve block.
Where is the needle inserted in a transtracheal block? Cricothyroid membrane
For a superiorlaryngeal block where is 2ml of Lidocaine injected? Base of thyroid cartillage
Where is 2ml of lidocaine injected for a glossopharyngeal block? Base of tonsilar pillar
Ovassapian airway is placed before airway is anesthetized? T/F fALSE- Placed AFTER!
What are the components of a fiberoptic scope? Light source, handle and flexible insertion tube.
Fiberoptic light source has a HIGH potential for fires? T/F FALSE- Fires are rare with this source of light
At what point is the ETT threaded over the fiberoptic scope? Right before intubation and not sooner.
Inside diameter of ETT should be------mm larger than diameter of cord for oral intubation 1
Inside diameter of ETT should be ------- mm larger than insertion cord for nasal intubation. 2
What is the most fragile part of the fiberoptic scope? The fiber bundles- They are easily damaged
The fiberoptic scope has an optional feature on its working channel. Name 4 functions of this feature. 1. Suctioning, 2. Injection of water, 3.Inssuflation of Oxygen 4. Passage of instruments
LOC is associated with loss of muscle tone that supports the tongue and epiglottis. T/F True
I will not administer a vasoconstrictor if I plan a nasal intubation. RIGHT OR WRONG Wrong- Nasal passages are very vascular, a vascoconstrictor minimizes bleeding.
The body of the scope is held in------- Dominant Hand
There is a need to align the oral, laryngeal and pharyngeal axis when using a glideoscope> T/F False
Give 3 reasons when a Bullard Laryngoscope be used? During difficult intubations, c-spine injury, limited mouth opening
What is the difference between a Bullard laryngoscope and a Fiberoptic scope? The Bullard is rigid and the fiberoptic scope is flexible.
When using the Light wand, what anatomical structure lights up to indicate entrance into the trachea? Midline of Thyroid prominence.
While using the Light wand the SRNA notices that the light has disappeared, what is this an indication of? The SRNA has intubated the esophagus. Retract the tube till light is seen again.
Name 6 contrindications to the use of the lighted intubation stylet or Light wand. 1. Scar tissue 2. Flexion contracture 3.Excesive adipose tissue 4. edema 5. Inability to darken the work area. 6.Bulb covered with blood/secretions.
