Adult Sepsis: How is Push-Dose Epinephrine prepared and administered?

• A. 1 mL of 1:10,000 Epi/9 mL Normal Saline (1 mL every 30 seconds)
• B. 1 mL of 1:1000 Epi/9 mL Normal Saline (every 10 seconds)
• C. 2 mL of 1:10,000 Epi/9 mL Normal Saline (every 60 seconds)
• D. 0.5 mL of 1:10,000 Epi/9 mL Normal Saline (every 15 seconds)

Answer: (A)

Push-dose epinephrine is used to rapidly and titrably raise blood pressure in hypotensive adults (like sepsis) by giving small, controlled boluses. The standard preparation is a 1:10,000 epinephrine dilution: take 1 mL of 1:10,000 epinephrine and add it to 9 mL of normal saline, creating a 10 mL syringe with about 10 micrograms per milliliter. Each 1 mL dose then delivers roughly 10 micrograms. Administering 1 mL every 30 seconds provides quick, incremental pressor effect to support perfusion while a continuous IV vasopressor is arranged, allowing careful titration and reducing the risk of overshooting blood pressure or provoking tachyarrhythmias. Using a more concentrated solution (such as 1:1000) would deliver much more epinephrine per dose and increase danger, while larger or differently dosed amounts (like 2 mL or 0.5 mL) would misalign with the typical 10 mcg per dose target and disrupt safe titration.
