Q

Asthma:

Pathophysiology?

A
  • 1) Airway hyperresponsiveness
    • Muscle constriction, edema, mucous production
    • “Late phase” reaction at 4-12 hours - inflammatory cells and mediator
    • Air trapping –> dead space ventilation –> V/Q mismatching
  • 2) Chronic inflammation

Rings and slings

Gastroesophageal reflux

Cardiac disease

30
Q

Therapy for asthma?

A
  • Albuterol (nebulized if severe, puffs if not)
  • Ipratropium (anticholinergic bronchodilator–less potent than albuterol–always used in conjuction with albuterol)
  • Corticosteroids
  • MgSO4
  • Parenteral ß-agonists (epinephrine or terbutaline)
31
Q

Side effects of albuterol:

A

Tachycardia

Hypokalemia

32
Q

When asthma patient needs to be admitted:

A

O2 requirement

Persistent respiratory distress (Need for treatments < Q4 hours)

Air leak

Underlying high risk factors ED visit last 24 hours

33
Q

Instructions to parents if the asthma patient is D/Ced home:

A

Observe 60-90 min after last treatment

“Action Plan”

STEROIDS

  • Oral 2 mg/kg per day for 4 days
  • Inhaled corticosteroids?

Educate

Follow-up with primary doctor

34
Q

Most likely diagnosis?

A

Bronchiolitis

35
Q
  1. Typical Pathophysiology of Bronchiolitis?
  2. Other viral causes?
  3. Bacteria?
  4. Season?
  5. Peak age?
  6. Oldest age?
A
  1. Usually due to RSV (85% of cases)
  2. Other viruses (RIPAM)
  3. Mycoplasma
  4. Winter and early spring
  5. Peak incidence in 2-8 month olds
  6. May be seen up to 2y/o
36
Q

What is the patho process of bronchiolitis?

A

RSV invades nasopharyngeal epithelium

Cell to cell transfer to lower airways

Cell death and sloughing

Mucous production

Airways edema and mucous plugging

37
Q

Role of airway hyperresponsiveness in bronchiolotis?

In which patients does apnea occur?
