Flashcards in Pulmonary Emergencies Deck (119):

Air way obstruction is most common in _________.

Children, children 1-3 yo are most susceptible. They more frequently place things in their mouths and lack molars for properly grinding their food. They are often running or playing at the time of aspiration.


What is the most common food item aspirated?



After foreign body aspiration where can the foreign body settle? Which place is the most common

The FB can settle into 3 anatomical sites, the larynx, trachea or bronchus. 80-90% of aspirated FBs become lodged in the bronchi (the right one being most common).


Where are larger foreign bodies more likely to be lodged?

The trachea or larynx


How do patients with laryngeal foreign bodies present?

Present with airway obstruction and hoarsness or aphonia


How do patients with tracheal foreign bodies present?

Present with coughing and can also demonstrate wheezing similar to asthma


How do patients with bronchial foreign bodies present?

Present with cough, unilateral wheezing and decreased breath sounds. Only 65% of patients have all 3.


Foreign body evaluation:

Two view CXR, findings that may be suggestive would be: unilateral hyperexpansion and lobar atelectasis or pneumonia


Suspected FB aspiration requires ____________. (Treatment)

bronchoscopic evaluation (aka: broncoscopy)


Angioedema is aka a _____________

Hypersensitivity reaction/allergic reaction


What are possible drug mediated hypersensitivity reactions?

ACE inhibitors and ASA


How do we treat angioedema?

Treat with antihistamines, steroids +/- epinephrine


What are the various etiologies of airway obstruction?

FB aspiration, Angioedema, Burns/Trauma, Mass (cancer) or Infectious (Croup, Epiglottitis and Peritonsillar Abscesses)


What are the symptoms of Croup?

Barking cough, stridor, prodromal URI symptoms


How do we treat Croup?

Single dose dexamethasone (PO or IM). Epinephrine indicated in moderate to severe cases.


____________ is the pathogen most commonly identified with epiglottitis. It causes a _____________ presentation.

H. influenza b; more severe


Lesser pathogens associated with epiglottitis:

Staph and Strep


What is the gold standard for the diagnosis of epiglottitis?

fiberoptic laryngoscopy


Besides the gold standard for diagnosis for epiglottitis, what are other diagnostic criteria?

lateral soft tissue neck x-rays are up to 90% sensitive.

Think thumbprint sign!


What is the treatment for epiglotittis?

Children are more likely to require airway protection, awake fiberoptic intubation is ideal.

Begin 3rd gen. cephalosporin + vancomycin or clindamycin


Who is more likely to develop a Retropharyngeal abscess?

Increasingly more common in adults.


What are the most common organisms associated with Retropharyngeal abscess?

Typically polymicrobial: anaerobes, Staph are most common flora


How does a patient with a Retropharyngeal abscess present?

Classically presents with sore throat, neck pain/stiffness, dysphagia and “hot-potato” voice


How do we diagnose a Retropharyngeal abscess?

On normal lateral soft tissue neck X-ray, soft tissue anterior to C1-C4 should be < 40% of the diameter of the adjacent vertebral body. Widening of this space suggests infection.


What is the treatment for a Retropharyngeal abscess?

Treatment is IV antibiotics and operative I and D


What is Ludwig’s Angina?

A progressive infection of the connective tissues of the floor of the mouth and neck which begins in the submandibular space.


What is the pathophysiology of Ludwig’s Angina?

Most commonly caused by infection originating in the area of the 2nd or 3rd molars


What is the patient presentation of Ludwig’s Angina?

Exam reveals bilateral submandibular swelling, elevation of the tongue, dysphonia


What is the treatment for Ludwig’s Angina?

Airway should be secured, preferably via fiberoptic guidance. Antibiotic coverage for oral flora, e.g. ampicillin-sulbactam, clindamycin.


How is a Peritonsillar Abscess diagnosed?

Diagnosed on the basis of infero-medial displacement of the infected tonsil with resulting uvular deviation. Needle aspiration confirms the diagnosis and is therapeutic.


Peritonsillar Abscess Treatment:

Larger abscesses may require I and D by ENT. Typical antibiotic coverage is amoxicillin/clavulanate, clindamycin also commonly utilized.


What is Aspiration pneumonitis?

Aspiration pneumonitis represents an acute, chemical lung injury resulting from the inhalation of gastric contents.


What is the pathophysiology of Aspiration pneumonitis?

It occurs when a patient inhales material from the oropharynx that is colonized by upper airway flora.


Diagnosing Aspiration pneumonitis:

Consider this diagnosis in patients with even transient alterations in level of consciousness resulting from dementia, delirium, seizures, CVAs, drug intoxication or head trauma.

Includes impairment of gag reflex, coughing, ciliary movement, and immune mechanisms, all of which aid in removing infectious material from the lower airways.


Who is most likely to develop Aspiration pneumonitis?

Most commonly occurs in individuals with chronically impaired airway defense mechanisms.


Causative organism of Aspiration pneumonitis:

Once thought to be primarily caused by anaerobic organisms but newer data suggests typical URI flora are more common
• S. pneumoniae
• S. aureus
• H. influenzae

Hospital-acquired cases are more likely to involve Staph, Pseudomonas


How is aspiration pneumonitis treated?

Prophylactic antibiotics generally not recommended in case of aspiration pneumonitis. No role for corticosteroids.

Treat aspiration pneumonia as you would pneumonia based on the setting it was contracted in (community vs. healthcare-associated).

In addition, anaerobic coverage is typically used to complement traditional pneumonia treatment.


What is Hyperventilation?

Not limited to tachypnea-may also refer to abnormally deep respirations.


What causes hyperventilation?

While anxiety is a very common cause of this presentation, must consider organic etiologies:
• PE, along with other causes of hypoxemia
• Pain
• Acidemia (i.e. DKA)
• Obstructive lung disease
• Interstitial lung disease
• Sepsis
• Salicyclate overdose


How do we treat hyperventilation?

Treatment depends on underlying etiology. Consider administration of a benzodiazepine in the ED once organic illness excluded.


T/F: Pulmonary embolisms need to be diagnosed early. They are easy to diagnose but can be life threatening.

False, PE is traditionally difficult to diagnose. Missed diagnosis results in a large number of malpractice claims. Fear of missing the diagnosis results in frequent (negative) testing-with potential negative outcomes for patients.


PE triad:

Hypercoagulability, Stasis, Vessel injury


Risk Factors for a PE

Hypercoagulability, Venous Stasis, Venous Injury


What puts a person at risk for Hypercoagulability?

- Malignancy

- Nonmalignant thrombophilia: Pregnancy, Postpartum status (<~4wk), Estrogen/ OCP’s, or Genetic mutations (Factor V Leiden, Protein C & S deficiency, Factor VIII, prothrombin mutations, AT-III deficiency).


What puts a person at risk for Venous Stasis?

Bedridden status, Recent cast or external fixator and Long-distance travel


What puts a person at risk for Venous Injury?

Recent surgery requiring general anesthesia or Recent trauma (especially the lower extremities and pelvis).


Pathophysiology of a Pulmonary Embolism:

Venous emboli (typically from the lower extremities) may become dislodged from their site of origin, embolizing to the pulmonary arterial circulation or, paradoxically to the arterial circulation through a patent foramen ovale.

Pulmonary vascular resistance abruptly increases, causing increased RV wall tension and RV dilation and dysfunction

Elevated troponin and BNP predict mortality. Progressive right heart failure is the usual immediate cause of death from PE.


What is the Clinical Presentation of a Pulmonary Embolism?

Most common symptoms present in patients with proven PE: Dyspnea (84%), Chest Pain, pleuritic (74%), Anxiety (59%), Cough (53%).

The Classic Triad: (Hemoptysis, Dyspnea, Pleuritic Pain). Not very common (Occurs in less than 20% of patients with documented PE).


How do we diagnose a PE?

Using vital signs, history and physical and chest X-ray, determine your pretest probability (PTP) of PE.

1. High PTP: Patients in whom PE can be reliably excluded only by imaging
2. Low-Moderate PTP: Patients safe for exclusion via negative D-dimer
3. Patients with such low pretest probability that no testing is indicated


EKG findings in a patient with a PE:

Moderate to severe PE results in increased PA and RV pressures, resulting in evidence of right heart strain on the EKG.

• Tachycardia
• Q wave in lead III
• Precordial T wave inversions


EKG in association with PEs

Limited sensitivity and specificity


Chest X-Ray

• Primary utility lies in identification of alternative explanation for patient’s symptoms (i.e. pneumothorax)
• Westermark's sign
• A dilation of the pulmonary vessels proximal to the embolism along with collapse of distal vessels, sometimes with a sharp cutoff.
• Hampton’s Hump
• A triangular or rounded pleural-based infiltrate with the apex toward the hilum, usually located adjacent to the hilum.
• Neither are commonly observed


What are the Wells Criteria?

Clinical evidence of DVT
PE most likely diagnosis
Immobilization > 3d; surgery within 4 wk
Prior DVT or PE
Active malignancy


Wells Score of 4 or greater suggest the patient should undergo imaging, score less than 4 implies D-dimer testing is appropriate first step in diagnosis



PE Rule-Out Criteria

Identifies a very low risk population for which the authors advocate no testing for PE
• Low clinical suspicion for PE in addition to:
• Age < 50 years
• Pulse < 100 bpm
• SaO2 > 94%
• No prior PE or DVT
• No unilateral lower extremity edema
• No hemoptysis
• No use of exogenous estrogen
• No trauma or surgery within 4 weeks



• If high pretest probability, proceed directly to CT scanning
• If low-moderate pretest probability, obtain D-dimer as first step in workup
• If D-dimer is below cutoff, PE is effectively excluded
• If D-dimer is elevated, proceed to CT scanning



• Fibrin split product
• Circulating half-life of 4-6 hours
• Quantitative test have 80-85% sensitivity, and 93-100% negative predictive value
• False Positives:
Pregnant Patients Post-partum < 4 weeks
Malignancy Surgery within 1 week
Advanced age > 80 years Sepsis
Hemorrhage CVA
AMI Collagen Vascular Diseases
Hepatic Impairment


Chest CT

• Advantages
• Noninvasive and rapid
• May provide alternative diagnosis
• Disadvantages
• Costly
• Risk of contrast nephropathy
• Risk of radiation


Alternative Strategies

• If concerns regarding risks of CT preclude this modality, may consider:
• V/Q Scan (limited availability at some institutions)
• Lower extremity venous dopplers (if DVT identified, anticoagulation is indicated anyway)
• Empiric treatment if sufficiently high pretest probability



• Anticoagulation
• Low molecular weight heparin (e.g. enoxaparin 1 mg/kg IV/SC bid)
• Unfractionated heparin (bolus with subsequent drip)
• Recent guidelines support preferential use of LMWH (no need for monitoring PTT)
• Works though activation of antithrombin III, resulting in inhibition of proteases necessary for coagulation cascade. Clot resolution will take days/weeks
• Consideration of thrombolysis/mechanical clot removal
• Definitely indicated in patients with hypotension
• Consider in patients with RV dysfunction on echo, elevated troponin/BNP
• IVC filter placement in patients with contraindication to anticoagulation or recurrent thrombus despite adequate anticoagulation


Traditional Stratification of PE Severity

• Massive PE
• Defined as PE resulting in systemic hypotension
• 5% of patients diagnosed with PE
• 30-60% mortality
• General consensus that lysis is indicated if no contraindications
• Submassive PE
• 95% of patients
• Mortality rate of <5%
• Most patients will go on to have an unremarkable course, require only anticoagulation if no contraindication


Means of Risk-Stratifying Patients with Submassive PE

• Markers of RV Dysfunction
• Echocardiography (best method, but limited availability)
• Biomarkers (Good sensitivity, limited specificity)
• Troponin
• Patients with abnormal RV function may benefit from more aggressive treatment (thrombolytics)


Acute Respiratory Distress Syndrome:

Accumulation of fluid in alveoli of lungs with resulting severe hypoxia, with non-cardiac etiology.

• Should be obtained in patients with status asthmaticus or patients with no prior history of wheezing
• BMP - useful for those on continuous nebulizers to monitor K+
• CBC - little/no utility (WBC increase with left shift is expected within 2 hours of steroid administration)



• In general, patients presenting to the ED should receive corticosteroids
