Term
Difficult tracheal intubation is when you have to attempt more than 3 times or spend longer than?
Definition
>10 minutes
Term
The nasopharynx is separated from the oropharynx by the ?
Definition
soft palate
Term
the _____ demarcates the border between the oropharynx and hypoharynx
Definition
epiglottis
Term
The vagus nerve provides sensation to the hypharynx via?
Definition
the internal branches of the superior laryngeal nerve
Term
The larynx sits between cervical __ and __
Definition
C3 - C6
Term
the vocal cords are formed by the
Definition
thryoartyenoid ligaments
Term
the narrowest portion of the adult airway is?
Definition
the vocal cords
Term
The trachea begins at cervical __ and extends to the carina which is at T?
Definition
C6 starts cervical and extends to the carina which is at T5
Term
The trachea is ___ cm long and supports by ___ horseshoe shaped cartilages
Definition
Trachea is 10-15 cm long and composed of 16-20 horsehoe cartilages
Term
What mallampati score will the fauces no longer be visible? What else is present for this score?
Definition
A mallampati III the fauces are no longer visible. What you can see is the soft palate, and possible the base of the uvula and hard palate.
Term
Acromegaly patients have a high airway risk for?
Definition
mandibular hypertrophy
Term
The shape of the palate may be predictive of airway complications. What findings are you looking for?
Definition
1. highly arched palates are bad sign
2. narrow palates are a bad sign
Term
What neck shape may make someone more at risk during your airway assessment?
Definition
Short necks and Thick NeckS! Bad finding
Term
Whats the name for the neck movement needed to get all three axis' in alignment for optimal tracheal intubation
Definition
antlanto-occipital extension
Term
normal atlanto-occipital extension
Definition
35 degrees
Term
IF you had to do a cricothyroidotomy and the person does not have a pronounced laryngeal prominence then resort to identifying the cricoid cartilage compared to tracheal rings..whats the difference
Definition
Start at the sternal notch and palpate the tracheal cartilage as you work your way up. The cricoid cartilage will be wider and higher compared to tracheal cartilage.
Term
edentulous means?
Definition
lacking teeth
Term
Mallampati class x? is predictive of difficult facemask ventilation
Definition
Mallampatti class III and IV
Term
the minute ventilation for oxygen (MV02) for an adult with an ideal body weight is?
Definition
3 mL/kg/min
Term
What are some good tenchniques to ensure adequate 100% oxygenation of the entire FRC prior to intubation
Definition
3 minutes of tidal volume breathing 100% or 8 large breaths in 60 seconds is also equivalent.
Term
Limit ventilation pressure of the bag valve mask to less < ___ cm to avoid gastric insufflation
Definition
<20 cm on BVM
Term
An oral airway can cause what bad side effects
Definition
1. larygeal spasms
2. gag reflex
Term
nasal airways are contraindicated in what patients 3x
Definition
1. basilar skull fractures
2. coagulation abnormalities
3. platelet abnormalities
Term
cricoid pressure for better view is also known as?
Definition
Sellick's maneuver
Term
standard intubating blades for adults for the mac and miller are?
Definition
MAC: 3 or 4
Miller: 2 or 3
Term
what property of the tracheal tube allows it to be seen on xray
Definition
the end is radio opaque for visualization during CXR
Term
How far does the tracheal tube go into the trachea?
Definition
You want the top of the cuff to be at 1-2 cm past the vocal cords.
Term
Where should the tip of the tracheal tube lie?
Definition
half way between the vocal cords and carina
Term
ciliary denudation can occur under the cuff after only how long being intubated
Definition
after only 2 hours of intubation
Term
what kind of patient would you consider using a fiberoptic scope for intubation
Definition
known cervical injury
Term
an absolute contraindication to fiberoptic intubation is?
Definition
TIME. Technique requires time to set up.
Term
What drug is important to give prior to fiberoptic intubation to help prevent disrupting video quality? Describe this class of drugs phsyiology
Definition
give an antisialagogue which will decrease saliva. Atropine can do this. Anticholinergics have this affect as well. Glycopyrloate is another option.
Term
how much glycopyrrolate is given to act as a antisialagogue
Definition
0.2 mg IV
Term
What is a cornu? give two examples
Definition
cornu a structure with a shape likened to a horn, in particular.
a horn-shaped projection of the thyroid cartilage or of certain bones (such as the hyoid and the coccyx).
Term
Describe the procedure for transtracheal block, what equipment needed also
Definition
Need a 20 gauge needle attached to a syringe with 4 mL of a local anesthetic. Find the cricothyroid membrane and begin inserting needle slowly while aspirating to identify if you hit a vessel (bad) or aspirate air (Good! thats the goal) When air is aspirated stop and advance catheter and remove needle. Reattach the LA filled syringe and again reconfirm you are in the trachea (you should be able to aspirate air) then rapidly inject LA
Term
What trick can you do to help facilitate nasal fiberoptic intubation which will have less trauma? What size tube do you choose
Definition
warm the ett prior with water. Use a size tube that is 1.5 mm larger than the diameter of the fiberoptic bronchoscope.
Term
what are three methods for anesthetizing a patients upper airway
Definition
1. larynx and trachea local A topicalization
2. Superior laryngeal nerve block
3. transtracheal block
Term
what other device can provide an excellent channel for awake oral fiberoptic intubation
Definition
AN LMA! Since it sits over the larynx it will help facilitate the ETT into the right area.
Term
McGrath scope, glidescope, pentax are examples of what type of laryngoscopes?
Definition
rigid fiberoptic laryngoscopes
Term
The most SNS stimulating thing we do to patients during surgery is?
Definition
laryngoscopy!
Term
what's the difference between a king airway and combitube
Definition
combitube is two proximal lumens with one distal end that has two lumens (a side port and a distal end) It has two cuffs that need to be inflated. Ventilate through the tube that accesses the lungs.
Term
when do you release cricoid pressure after intubation
Definition
ONLY AFTER TUBE IS CONFIRMED
Term
What ASA classifcation would you give a patient with unstable angina
Definition
ASA 4
Term
What ASA classifcation would you give a patient with hepato-renal failure
Definition
ASA 4
Term
