Airway Assessment Flashcards
Name these structures.
Give 6 indications for intubating a patient.
- Airway protection (protect from gastric secretions, etc)
- Maintenance of patent airway
- Application of positive pressure ventilation
- Maintenance of adequate oxygenation
- Deliver predictable FiO2
- Provide PEEP
List 6 good reasons to use just a mask for a case.
- It is good because no instrumentation of the airway is required, therefore you avoid trauma and CV stimulation.
- Difficult airway not present
- Sugeon does not to access head and neck
- No airway bleeding/ secretions
- Case is short in duration
- No table position change/ head available
What has to be present for a good mask ventilation?
You must be able to make a good seal between the mask and the face to overcome upper airway obstruction. Any obstruction should be easily relieved by airway/ chin lift.
Give 6 good airway assessment questions you should ask your patient?
- Previous anesthesia Hx with airway management
- Difficulty with prior anesthetics/ intubations
- Past awake or fiberoptic intubation
- Severe sore throat or dental damage
- Co-existing disease (goiter, ever had a tracheostomy, ever had a neck dissection)
- surgical history that may affect airway management
List 11 co-morbidities a patient may have that would affect airway management.
- Lesions of the larynx
- Thyroid disease
- Cancer
- GERD
- Diabetes
- Sleep Apnea
- Obesity
- Genetic disorders
- Rheumatoid arthritis
- Musculoskeletal
- Scleroderma
T or F. If a patient has had a tracheostomy there is always some stenosis and fibrosis of the airway.
True
Name 4 past surgeries that may affect airway management.
- Tracheostomy or scar
- Neck dissection
- UVPP
- Cervical neck instrumentation (fusion)
What is Standard I of the AANA?
A practitioner should perform a thorough and complete pre-anesthesia assessment.
What is Standard III of the AANA?
The practioner formulates a patient specific plan for anesthesia care.
Which airway measurement is directly related to the size of the tongue?
Mallampati score
Mandibular Protrusion Test. This is an example of which class?
Mandibular Protrusion Test. This is an example of which class?
Mandibular protrusion test. Which class is this?
How would you test neck range of motion in your pre-op patient?
Full ROM should be 90-165 degrees
How many teeth do we have?
We have 32 teeth. 16 on top and 16 on the bottom. Start counting from Right upper jaw and around and then down in a circle.
What 6 things do you want to assess in the dental assessment?
- poor dentition
- loose teeth
- chipped teeth
- capped
- removable bridges
- dentures
What information does the Mallampati exam give us?
It relates the size of the base of the tongue to the oral cavity
The Mallampati test gives us visualization of:
- pharyngeal structures
- soft palate
- fauces
- uvula and pillars
How do you perform the Mallampati exam?
Pt sitting up with head in a neutral positon opens mouth wide, but does not say AHHHHH (phonation can inappropriately elevate the soft palate)
What Mallampati class is this airway?
Class 1. The entire uvula, pillars, fauces, and soft and hard palate are visible.
What Mallampati class is this airway?
Class 2. Only part of the uvula, fauces, and soft and hard palate are still visible.
What class is this airway?
Class 3. Only the base of the uvula is visible. along with the soft and hard palates. no fauces or pillars visible.
