Q

What is the tx plan for CHF?

A
  1. Adequate oxygenation and ventilation
  2. Nitroglycerin (reduces preload/BP)
  3. Morphine Sulfate (decreases preload/anxiolysis)
  4. Diuretic (Furosemide MC, Bumetanide can also be used)
  5. +/- Dobutamine (Not commonly used)

26
Q

The following CT results show what condition? Which side is more severe?

A

Pulmonary embolism

Left= saddle PE (usually fatal)

27
Q

How do you tx a pt w/ a PE?

A
  1. Anticoagulation
    • Heparin
    • Coumadin
    • Lovenox
    • Rivaroxaban (Xeralto)
    • if anticoag CI: vena caval filter
  2. +/- Thrombolytics for massive PE if not contraindicated (major bleed w/in 6 mo, recent surgery, suspected aneurysm, etc)
    • Streptokinase
    • Urokinase
    • Alteplase (Activase) tPA–> only one FDA approved
  3. +/- embolectomy (if massive PE w/ CI to fibrinolysis)
  4. +/- catheter directed thrombolysis (if CI to fibrinolysis)
28
Q

How would you tx a pt w/ a massive PE?

A
  1. Anticoagulation
    • Heparin, Coumadin, Lovenox, Rivaroxaban
    • Venal caval filter if CI to anticoag
  2. Thrombolytics
    • Streptokinase
    • Urokinase
    • Alteplase (Activase) tPA--> only one FDA approved
  3. +/- Embolectomy if CI to fibrinolysis
  4. +/- Catheter directed thrombolysis if there are contraindications to the other treatments
29
Q

How do you tx a massive PE with contraindications to fibrionlysis or unstable after fibrinolysis?

A
  1. Anticoagulation
  2. Embolectomy
30
Q

What is Catheter directed thrombolysis used to tx and what meds are used?

A

Massive PE

  1. —Alteplase infused over 4 hours
  2. —Begin heparin infusion (no bolus) after alteplase completed
31
Q

How do you tx asthma/COPD in the ED?

A
  1. Beta agonist- Albuterol
    • via MDI or nebulizer (both have equal efficacy but prob use nebulizer in ED b/c easier)
  2. Ipratropium Bromide (given w/ albuterol)
  3. Corticosteroids
    • Dexamethazone, Methylprednisolone, Prednisone
    • high dose steroids not recommended
  4. Magnesium sulfate (for severe exacerbations)
  5. Heliox (MCly used in peds but not usually recommended)
  6. +/- Ketamine (conscious sedation)
  7. +/- Epinephrine (studies show no better than albuterol)
32
Q

Would you give a beta agonist continuously or intermitently in a severe asthma/COPD exacerbation seen in the ED?

A

continuous

33
Q

What med is no longer recommended in the tx of asthma/COPD exacerbations?

A

Theophylline

(b/c of narrow therapeutic window and many side effects)

34
Q

instead of using a beta agonist, Ipratroprium bromide and corticosteroids to tx asthma/COPD in the ED, what else can be used?

A

Non-invasive ventilation:

BiPAP- bilevel positive airway pressure (pt usually comes in on CPAP and is switched over to BiPAP b/c this is more physiologically normal)

(for moderate-severe dyspnea but no need for intubation)

35
Q

When should FB aspiration ALWAYS be considered?

A

In kids w/ unilateral wheezing and persistent sxs that don’t respond to bronchodilators

36
Q

What does the following CXR show?

(this is very subtle and probably won’t be on the exam)

A

Hyperexpansion of the R lung due to FB aspiration

37
Q

Where is this FB? Why?

A

Esophageal FB in the Thoracic inlet =

  • Thoracic inlet b/c at the level of the clavicles, site of anatomical change from skeletal to smooth mm, also transition of cricopharyngeum mm
  • Esophageal b/c coin is flat, and posterior to trachea (black line on right pic)

(test question)

38
Q

Where is this FB?

A

Esophageal FB

(b/c can see trachea/black line to the left)

39
Q

Where is this FB

(this is tricky, prob won’t be question)

A

Esophageal FB (b/c below bifurcation of the trachea)

Thoracic inlet, mid or GE junction

40
Q

Where is this FB located?

A

Right mainstem bronchi

41
Q

What is concerning about this FB?

A

It is a button battery! Can cause necrosis and burn hole through structure

MUST BE REMOVED

42
Q

How do you tx FB aspiration in a conscious patient?

A

Ask “are you choking” and “may I help you”

if pt can answer then let them cough, if can’t then perform the heimlich maneuver

43
Q

How do you tx a FB aspiration in an infant/child?

A

place infant stomach down across your forearm and give 5 quick, forceful blows on the infants back w/ the heel of your hand

44
Q

How do you tx a FB aspiration in an unconscious patient? What should you not do?

(do NOT perform blind finger sweep)

Q

You are evaluating a 56 year old male with history of colon cancer, on chemotherapy, who presents w/ SOB. Vitals: 90/40, 123, 28, 87% RA, 101.1. You give IV fluids, O2 and monitor. CXR is negative. What is your next step?

Order CT

CT shows BI PE so give anticoagulation
