Q

Epinephrine ADULT
1mg/mL= 1:1,000
0.1mg/mL= 1:10,000

A

Cardiovascular collapse:

-IV infusion (0.5mcg/kg/min) of 1mg/mL epi when present despite repeated epi IM doses & at least 60mL/kg isotonic fluid boluses

Prepare infusion by mixing 1mg 1mg/mL epi in 250mL NS (4mcg/mL)

Profound bradycardia w/ signs of hemodynamic instability:

-IV/IO infusion of 0.02 - 0.2mcg/kg/min 1mg/mL epi titrated to a MAP>65

-Or IV/IO push dose 10-20mcg boluses (1-2mL) every 2min titrated to a MAP>65
-Prep push dose by adding 1mL of 1mg/mL epi to 9mL of NS; results in 10mcg/mL concentration

Shock unresponsive to IV fluids or Cardiogenic shock w/ signs of fluid overload:

-IV/IO infusion 0.05 - 0.3mcg/kg/min

Cardiac arrest:

-Give 1mg of 0.1mg/mL IV/IO every 5min. Follow each dose with a 20mL flush & elevate arm for 10-20 sec after each dose
