In a child with distributive (warm) septic shock, which hemodynamic profile best describes the expected findings?

• A Low cardiac output, high SVR, cold extremities
• B Low cardiac output, low SVR, cold extremities
• C High cardiac output, high SVR, warm extremities
• D High cardiac output, low SVR, warm extremities, wide pulse pressure ✓

Explanation

Distributive (warm) septic shock is characterized by vasodilation with low systemic vascular resistance (SVR), resulting in a compensatory rise in cardiac output, warm extremities, and a wide pulse pressure (due to low diastolic pressure). This contrasts with cold shock, which features low cardiac output and high SVR with cold, mottled extremities. Recognition of the shock subtype guides vasoactive drug selection.
