When to use what airway device given a scenario / When to use

what ventilation device given a scenario: Non-Rebreather -

ANSWER- Used for patients that require more than 6L of

oxygen, and can be used with a nebulizer for maximum

efficiency.

When to use what airway device given a scenario / When to use

what ventilation device given a scenario: BVM - ANSWERBLS airway that is used initially before an advanced airway, and

connected to one if one is placed.

TX of a patient in anaphylaxis when epinephrine has failed to

improve the patient's condition and he/she is deteriorating -

ANSWER- If 0.3mg IM 1:1000 Epi does not work, peripheral

perfusion isn't good enough to circulate the medication! IV EPI:

1:10,000 is the only solution to get the epinephrine to the

patient.

Know the advantages and disadvantages of a surgical vs needle

cricothyrotomy. Which one is the quickest to perform? -

ANSWER- Once established, surgical cricothyroidotomy has a

number of advantages over use of a cannula - provision of a

definitive airway (protection by a cuffed tube) being just one.

Despite this, the technique is used far less frequently. This may

be due to fears about the complication of hemorrhage.

Research suggests that needle cricothyroidotomy can provide

effective ventilation in the presence of increasing airway

obstruction. The failure of the needle systems in the presence of

upper airway obstruction results from inadequate exhalation via

the narrow 1.5mm lumen of the 13G cannula. Which can lead

to:

Barotrauma/pneumothorax = from over-inflation*

Bleeding

Subcutaneous emphysema

Survey data from the prehospital and hospital settings show the

needle airway to be the most frequently used emergency

cricothyroidotomy method, whereas the surgical airway is rarely

used.

Assessment findings in a patient with a spontaneous

pneumothorax - ANSWER- Shortness of breath, sudden onset of

sharp chest pain, pallor, tachypnea, diaphoresis.

Severe symptoms include tachycardia, AMS, cyanosis,

decreased breath sounds on the affected side.

Best method to protect a patient's airway who vomits each time

you try to intubate - ANSWER- Inadequate depth of anesthesia

or unexpected responses to surgical stimulation may evoke

gastrointestinal motor responses, such as gagging or recurrent

swallowing, increasing gastric pressure over and above LOS

pressure facilitating reflux.

In the setting of aspiration, regurgitation occurs three times more

commonly than active vomiting. An unprotected airway,

excessively light depths of anesthesia, and one or more

predisposing risk factors for aspiration combine to significantly

increase the risks of aspiration.

A summary of the available strategies for reducing aspiration

risk:

Reducing gastric volume (NRB instead of BVM)

Second-generation supra-glottic airway devices

Cricoid pressure

Rapid sequence induction

Position (left lateral, head down or upright)

What are the advantages / disadvantages of tracheal intubation

vs using an extraglottic airway device? - ANSWER- Insertion of

a supraglottic airway device is simpler and faster than tracheal

intubation, and proficiency requires less training and ongoing

practice.

Tracheal intubation is a more complex skill than supraglottic

airway device insertion and requires 2 practitioners, additional

equipment, and good access to the patient's airway

The strategy of using a supraglottic airway device first also

achieved initial ventilation success more often. Although

regurgitation and aspiration occurred with similar frequency

overall, regurgitation and aspiration during or after advanced

airway management were significantly more common in the

supraglottic airway device group. Conversely, patients in the

tracheal intubation group were significantly more likely to

regurgitate and aspirate before advanced airway management,

possibly due to less frequent use of advanced techniques to

secure the airway in this group and the increased time required

for tracheal intubation compared with insertion of a supraglottic

airway device.
