How often can nebulized adrenaline be repeated for severe croup management?

Nebulized adrenaline is an effective treatment for severe croup as it helps to reduce airway swelling and improve breathing by causing vasoconstriction in the upper airway. The recommended frequency for administration of nebulized adrenaline, when used in the management of severe croup, is every 30 minutes as needed. This timing allows for adequate spacing between doses, while still providing timely relief from respiratory distress.

Repeated doses more frequently than every 30 minutes could lead to a higher risk of potential side effects, such as tachycardia or hypertension, which can arise from the systemic effects of adrenaline. Therefore, adhering to the established guideline of every 30 minutes helps strike a balance between effective symptom relief and patient safety.
