3: Status Asthmaticus Flashcards
1
Q
What are the 3 treatment goals for status asthmaticus?
A
- Correction of significant hypoxemia with supplemental oxygen.
- Severe cases with alveolar hypoventilation require mechanically assisted ventilation.
- Rapid reversal of airflow obstruction with repeated or continuous administration of an inhaled beta2-agonist.
- Early administration of systemic corticosteroids (e.g., oral prednisone or intravenous methylprednisolone) suggested in asthma that fails to respond promptly and completely to inhaled beta2-agonists.
- Reduction in the likelihood of recurrence of severe airflow obstruction by intensifying therapy with a short course of systemic corticosteroids is helpful.
