Airway Rotation Pre-Test

The most sensitive criteria to predict a difficult intubation is:
Mallampati 3
History of previous difficult intubation
Head and neck extension less than 50% from neutral
Neck circumference of 30 cm
Emergent intubation
The following is a correct statement regarding the straight (Miller) blade vs. a curved (Macintosh) blade:
The Macintosh blade is easier to operate, while the Miller blade provides a better view of the vocal cords.
The Macintosh blade is the preferred blade to expose the laryngeal inlet in infants and children during tracheal intubation
The Macintosh blade is straight, and it is passed so that the tip lies beneath the laryngeal surface of the epiglottis
The Miler blade is rarely used in modern anesthesia pratice
Miller blades only comes in sizes 1, 2 and 3
The recommended amount of cuff volume for a size #4 LMA is:
up to 20 mL
Up to 30 mL
Up to 40 mL
Up to 50 mL
Up to 60 mL
The incidence of unexpected difficult ventilation/intubation is higher in what population?
Infants
Adolecents
Elderly
Pregnancy
Diabetics
-What is the the recommended surgical approach to a cannot ventilate/ cannot intubate scenario and exhaustion of other possibilities:
Percutaneous Crycothyroidotomy
Open Crycothyroidotomy
Tracheostomy
Transtracheal Jet Ventilation
All of the above
After preoxygentation RSI fails. You obtain a grade III/IV view. What is the next best step?:
Use a gum elastic bougie
)Place an LMA
Change blades
Cricothyrotomy
Retrograde wire intubation
The least sensitive method to detect correct ETT placement in the trachea is:
Fogging and humidification of the tube
Auscultation of chest
Presence of exhaled CO2
Outward movement of the chest upon inspiration
Hemodynamic response at intubation (tachycardia and hypertension)
A patient with prior history of radiation to the head and neck presents to the OR in severe respiratory distress. Which of the following is the most appropriate technique to secure the airway?:
Sleep FOB intubation
Retrograde intubation
Intubation via ILMA under local anesthesia
Awake tracheostomy under local anesthesia
Awake FOB under local anesthesia
Each of the following is a recommended maneuver in the Non-emergent ASA Difficult Airway algorithm branch except:
Classic LMA
Fastrach LMA
Fiberoptic Intubation
Transtracheal Jet-ventilation
Light Wand
Regarding difficult mask ventilation the following is true:
It is always associated with difficult Laryngoscopy and Intubation
Very common in people > 40 years of age
It is common in the elderly people without teeth
It is more common in adolecents
Is not an indication to call for help
