Clinical Questions Flashcards

1
Q

What are the mainstay characteristic of pulmonary hypertension?

A

Continuous high blood pressure in the PULMONARY arterities

normal pulmonary artery pressure (PAP) = 8 - 20 mmHg

PH = or > 25 mmHg with normal fluid status

Q

What are the different PH groups?

A

Group 1 = PAH - due to factors like heredity, drugs, HIV, liver disease
(or no cause called primary or idiopathic)

Group 2 = PH due to left heart disease

Group 3 = PH due to lung diseases

Group 4 = chronic thromboembolic pulmonary hypertension (mainly in pulmonary embolism survivors)

Group 5 = PH with unclear mechanism

Q

What is the pathophys of PAH?

A

Imbalance in substances like: vasoconstrictors (Thrombozane A2 and Endothelin-1) are increased and vasodilator (Prostaglandins) are decreased.

When not treated, the high blood pressure in the pulmonary vasculature can lead to pulmonary artery cell wall thickening and scarring which causes the RIGHT ventricle to work harder at pumping out blood === HEART FAILURE

PMH:

Doctors also said her PAP was 45 mmHg. A right catherization was performed, and the vasoreactivity test showed a decrease to 35 mmHg. What is a good treatment recommendation for the PAH?

A

Oral CCB - nifedipine, amlodipine, diltiazem

NOT verapamil (too much negative inotropic effect)

Q

A 12 yo patient presents with wheezing and chest tightness which began while playing frisbee at a park. This patient has asthma and is currently on a ProAir rescue inhaler. She usually has wheezing at least 4 times a month but rarely twice in one week does she need her rescue inhaler. How would you treat her asthma symptoms?

A

Step 2:
Already has rescue inhaler…

Add on a low-dose ICS for maintenance like:
-Betaclomethasone (QVAR) 200 mcg daily
-Budesonide (Pulmicort) 400 mcg daily
- Fluticasone (Flovent or Arnuity) 250 mcg daily
- Mometasone

Q

A 9 yo patient presents with wheezing and chest tightness which began while asleep. This patient has asthma and is currently on a ProAir rescue inhaler and Pulmicort 90 mcg 2 inh BID. She usually has wheezing 5 days of the week and wakes up with chest pain 2-3x per week needing her rescue inhaler. How would you classify and treat her asthma symptoms?

A

Uncontrolled asthma!!!
- switch Pulmicort to to Symbicort (with formoterol) for her maintentance inhaler

-switch Pulmicort to Advair or Breo or Dulera

**may also which rescue inhaler to low ICS + formoterol
