A 7-year-old girl is brought to the emergency department experiencing an acute severe asthma exacerbation. She is visibly distressed with supraclavicular retractions, scattered wheezing, and an oxygen saturation of 89% on room air. Arrange the following interventions in the most appropriate stepwise order of priority and escalation, from the immediate first step to the appropriate step for refractory symptoms.
- 1Apply supplemental oxygen
- 2Administer nebulized albuterol
- 3Administer systemic corticosteroids
- 4Administer intravenous magnesium sulfate
Cevap
The correct sequence is: Apply supplemental oxygen, followed by nebulized albuterol, then systemic corticosteroids, and finally intravenous magnesium sulfate for refractory symptoms.
The initial management of a severe pediatric asthma exacerbation prioritizes reversing immediate life threats. Correcting hypoxemia with supplemental oxygen is the absolute first step. This is followed immediately by inhaled short-acting beta-agonists (like albuterol) to rapidly reverse bronchospasm. Systemic corticosteroids are administered next to target the underlying inflammation, though their clinical effect takes hours to manifest. Finally, if the patient does not respond adequately to these initial measures and remains in severe distress, adjunctive therapies such as intravenous magnesium sulfate are indicated.
