What is the preferred method to deliver bronchodilators to a child during an acute asthma attack?

• A. Inhaled bronchodilator via spacer with mask or spacer with MDI
• B. Nebulized bronchodilator without spacer
• C. Oral bronchodilator
• D. Intravenous bronchodilator

Answer: (A)

Delivering the bronchodilator directly to the lungs in a way a child can use reliably is essential for rapid relief. A spacer with a metered-dose inhaler achieves this best because it decouples actuation from inhalation, so the child can breathe in more easily and effectively, even if coordination isn’t perfect. The spacer increases the amount of medicine reaching the lower airways and reduces deposition in the mouth and throat, making the dose more efficient.

Using a mask with the spacer is especially helpful for younger children who can’t form a good seal around an inhaler, allowing quick, effective delivery during an acute attack. Inhaled therapy via spacer is fast, convenient, and well-suited to the emergency setting or at home.

Nebulized bronchodilators can be used when a spacer isn’t feasible or the child can’t use an inhaler well, but they are more time-consuming and resource-intensive, with similar overall effectiveness. Oral bronchodilators act systemically and have slower onset, which is less desirable for rapid relief. Intravenous bronchodilators are reserved for severe or life-threatening scenarios when inhaled methods aren’t possible.

So the preferred approach is an inhaled bronchodilator delivered via a spacer with mask or spacer with a metered-dose inhaler.
