Epi is likely beneficial in traumatic pulseless arrest?

• A. TRUE
• B. FALSE
• C. Only if other drugs fail
• D. Depends on mechanism

Answer: (B)

In traumatic pulseless arrest, the main issue is injury-related shock and reversible trauma causes (bleeding, airway obstruction, tension pneumothorax), not a primary cardiac rhythm problem. Epinephrine’s alpha-adrenergic vasoconstriction raises afterload and can worsen hemorrhage and reduce microcirculatory blood flow when there’s significant blood loss. With limited intravascular volume, this vasoconstriction doesn’t reliably improve perfusion to the heart and brain during CPR and can hinder ROSC. The correct approach is high-quality CPR, rapid hemorrhage control, airway/ventilation management, treatment of reversible trauma causes, and swift transport. So epinephrine is not likely beneficial as a routine intervention in traumatic pulseless arrest.
