What is the recommended management for a child diagnosed with asthma during exercise?

The appropriate management for a child diagnosed with asthma who experiences symptoms during exercise is the use of a bronchodilator prior to engaging in physical activity. Short-acting beta-agonists (SABAs), which are commonly used bronchodilators, work by relaxing the muscles of the airways, allowing for easier airflow and reducing bronchoconstriction that can occur during exercise. Using the bronchodilator approximately 15-30 minutes before exercise can effectively prevent exercise-induced bronchoconstriction, enabling the child to participate in physical activities with a lower risk of asthma symptoms.

In contrast, the other management options do not align with best practices for asthma management in the context of exercise. Oral steroids are typically indicated for more severe or chronic inflammation and are not used as a preventative measure for exercise-induced symptoms. Complete avoidance of physical activity is not advisable as it can lead to decreased physical fitness and an overall negative impact on the child's well-being. Antihistamines are generally used for allergic reactions and may not be effective in preventing asthma symptoms related to exercise. Therefore, the use of a bronchodilator is the most appropriate and effective strategy for managing asthma during physical activity.
