Distributive shock in children is most often due to:

• A. Sepsis
• B. Hypovolemia
• C. Cardiogenic failure
• D. Traumatic injury

Answer: (A)

Distributive shock happens when the blood vessels enlarge and blood pools peripherally, causing a relative drop in effective circulating volume and impaired tissue perfusion. In children, the most common trigger for this vasodilatory state is infection progressing to sepsis. The inflammatory response releases mediators that cause widespread vasodilation and increased capillary permeability, leading to the characteristic distribution of blood flow seen in distributive shock. While dehydration or blood loss (hypovolemia), pump failure (cardiogenic shock), or traumatic injury can cause shock, they do so mainly through reduced volume or impaired heart function rather than primary systemic vasodilation. Sepsis therefore best explains distributive shock in pediatric patients.
