In warm shock (sepsis or anaphylaxis), which intervention is indicated to restore perfusion?

• A. Fluids
• B. Positioning
• C. Antibiotics
• D. Vasopressors

Answer: (D)

Warm shock from sepsis or anaphylaxis is driven by widespread vasodilation that lowers arterial pressure and impairs organ perfusion. The key to restoring perfusion is raising the mean arterial pressure, which is best achieved with vasopressors. These medications tighten the blood vessels, increase systemic vascular resistance, and elevate MAP, thereby improving blood flow to organs. Fluids help by increasing circulating volume, but vasopressors address the main issue—the vasodilated state that keeps perfusion (MAP) low. In sepsis, norepinephrine is a common first-line vasopressor; in anaphylaxis, epinephrine serves a similar role with added bronchodilatory effects. Antibiotics, while essential for sepsis, and positioning or other supportive measures don’t restore perfusion as directly or rapidly as vasopressors in this scenario.
