What Is Croup? What Causes It?

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Croup is a common respiratory condition that primarily affects children, characterized by acute upper airway obstruction. It is most frequently observed in young children and is known for causing a distinctive barking cough, hoarseness, and stridor, which is a high-pitched wheezing sound resulting from turbulent airflow in the upper airway1.

Causes of Croup

Croup is typically caused by viral infections, with the parainfluenza virus being the most common culprit. Other viruses that can lead to croup include respiratory syncytial virus (RSV), adenovirus, and influenza. These viral infections lead to inflammation and swelling of the larynx, trachea, and bronchi, which results in the characteristic symptoms of croup1.

Treatment Approaches

The treatment of croup often involves the administration of steroids, such as dexamethasone, which are well-established in reducing airway inflammation and improving symptoms. The effects of steroids typically begin within 30 minutes of administration1. Additionally, recent research has explored the use of environmental interventions, such as exposure to outdoor cold air, as a complementary treatment. A study found that a 30-minute exposure to outdoor cold air (<10°C) can significantly reduce the intensity of croup symptoms, particularly in cases of moderate severity, when used alongside oral dexamethasone1.

In summary, croup is a viral-induced condition causing upper airway obstruction in children, with treatment options including steroids and potentially beneficial environmental interventions like cold air exposure.
