What is the recommended fluid bolus before administering push dose epinephrine?

• A. 1-2 liters IV fluid bolus, aiming for MAP ≥ 65 mmHg and SBP ≥ 90 mmHg
• B. 250 mL
• C. 3-4 liters
• D. No fluids

Answer: (A)

In shock management, securing adequate preload before starting vasopressor therapy is key. A fluid bolus helps restore venous return and improve stroke volume so that pressors can more effectively raise mean arterial pressure. The recommended amount is a 1–2 liter IV crystalloid bolus, with a goal of achieving a mean arterial pressure of about 65 mmHg (and SBP around 90 mmHg) to ensure sufficient organ perfusion.

Giving only a small volume, like 250 mL, may not be enough to improve perfusion in a vasopressor-requiring patient. On the other hand, large-volume resuscitation (3–4 liters) can risk fluid overload and complications such as pulmonary edema, especially in patients with cardiac or renal issues. Not giving fluids at all ignores volume status and can make vasopressors less effective.
