Distributive Shock
The most common cause of distributive shock is sepsis, followed by anaphylactic, toxicologic, adrenal, and neurogenic causes. Septic shock is multifactorial, with hypovolemic, cardiogenic, and distributive components.
Children with sepsis come in two varieties: warm shock and cold shock.
Distributive Shock: Act
Warm shock is due to peripheral vascular dilation, and is best treated with norepinephrine.
Cold shock is due to a child’s extreme vasoconstriction in an attempt to compensate. Cold shock is the most common presentation in pediatric septic shock, and is treated with epinephrine.
